Yuba County is home to California’s first 3D-printed community as first home hits the market
By Kayla Moeller
February 13, 2026
A first-of-its-kind neighborhood is taking shape in Yuba County. California’s first 3D-printed community is being built in Linda.
The first home is already for sale and the second and third homes are being printed right now.
“Five 3D-printed homes are going to be here,” said Nan Lin, founder of 4Dify.
The new neighborhood in Linda is being built one layer at a time with the latest in 3D printing technology from the company 4Dify.
The 1000-square-foot home for sale was printed from the dirt up within 24 days. It’s made up of mostly concrete.
“We’ve done ballistic testing on these, shot at it with 9mm, 45, 556, machine guns. These are bulletproof walls,” said Lin.
As the crew is getting the hang of things, they anticipate the next homes to be printed within just 10 days. Lin said printed homes are stronger and more efficient than regular homes.
“Because of how thick the walls are and the energy transfers between a concrete wall to a wood wall, the energy efficiency is extremely high. So you’re looking at half the energy bill and half the insurance costs,” said Lin.
Lin comes from Sacramento but has hit too much red tape to start construction there yet, but it’s on the horizon.
“I have a lot of good things to say about Yuba County. I didn’t know they were going to be so welcoming and also they’re also very innovation driven,” he said, “we’re looking to keep one machine here in Yuba County. We want to build more of these houses and more of these communities. However, we are expanding to Sacramento, Bay Area, SoCal.”
He says 3D printing increases productivity. The same five-person crew is able to print 10 to 12 homes per year, saving two months of construction time on each home compared to the traditional way.
“The issue I saw with construction is that the cost of employment and materials were all uncontrollable, always going up and there’s so many different variables that constantly change,” said Lin. “So 3D printing made a lot of sense because we get to control variables.”
It also helps to keep the cost down, with the first home priced at $375,000.
“We started construction on the second and third houses last week. The second house is about halfway up and the third, we’re just starting the foundation process,” said Lin.
Lin anticipates the entire community to be finished in June.
I have four questions for Bernie Sanders, Zohran Mamdani, and anyone else who believes that billionaires should not exist

I have four questions for Sanders, Mamdani, and anyone else who believes that billionaires should not exist.
But first, I’d like to present some background information before I ask those four questions.
Aluminum used to be so expensive that it was considered a precious metal. When they built the Washington Monument, they put a 20 pound piece of aluminum at the top. At the time, it was the biggest piece of refined aluminum in the world.
Since then, some greedy capitalists figured out how to make aluminum so cheap that today, people throw aluminum foil into the garbage.
Those greedy capitalists became billionaires because of what they did.
And we are all better off as a result.

The same thing is true for the people who created LEGO, Harry Potter, and so many other things. Those people became billionaires. And they did so by making other people better off.
Wikipedia has a list of billionaires per country. I clicked twice on the part where it says “rate,” so it would show the number of billionaires per capita in each country. Here is a screenshot of this that shows which countries have the highest number of billionaires per capita. This is only part of the list. The total number of countries that have billionaires is a lot longer, and you can read the complete list at the link.

The thing that I find most interesting about that screenshot is that it shows that Sweden actually has more billionaires, per capita, than the United States.
If you go to the link and read the entire list, you will see that there are certain countries that are not on the list, because they don’t allow people to become billionaires. North Korea and Cuba are two of these countries.
Regarding the countries that don’t allow people to become billionaires, immigration patterns prove that no one wants to live in those countries. All of the immigration regarding those countries is out of those countries. No one moves into those countries.
Now that I have presented this background information, here are my four questions for Bernie Sanders, Zohran Mamdani, and anyone else who believes that billionaires should not exist:
1) Would you rather be a middle class person today, or the richest person in the world 200 years ago?
2) Based on that wikipedia list, would you rather live in a real world country that has lots of billionaires, or in a real world country where it’s impossible for people to become billionaires?
3) Why do you think it’s a bad thing that the creator of Harry Potter became a billionaire?
4) What do you think of the fact that Sweden has more billionaires, per capita, than the U.S.?
I asked Grok to fact check my own claims about these 12 things being far better today than in the 1950s.
By Daniel Alman (aka Dan from Squirrel Hill)
July 7, 2025
I asked Grok:
Fact check:
Compared to the 1950s, here are some things that are far, far better in 2025:
Average life expectancy.
Square footage of housing per person. Houses today are much bigger, but the number of people in each house is much smaller.
Number of bathrooms per person in each house.
Percentage of homes with air conditioning.
Number of dental cavities for the average 18 year old.
Percentage of the population that is vaccinated against polio and measles.
Percentage of the population that has indoor plumbing.
Percentage of the population that takes a daily shower.
Being able to watch any movie that you want, whenever you want.
Size of average TV screen.
Percentage of the population that owns a color TV.
Percentage of the population that works at a desk inside an air conditioned office, instead of outside in the hot sun doing manual labor.
Every single one of these things is far, far better today than in the 1950s.
(end of my question)
This is Grok’s response:
Below, I’ll fact-check each claim by comparing the 1950s to 2025, using available data and historical context. I’ll aim to be concise while addressing each point thoroughly, citing sources where relevant. All claims will be evaluated for whether they are “far, far better” in 2025 compared to the 1950s.
1. Average Life ExpectancyClaim: Average life expectancy is far better in 2025 than in the 1950s.
Fact-Check:
1950s: Life expectancy at birth in the U.S. was 68.2 years in 1950 (65.6 for males, 71.1 for females).
2025: Life expectancy in 2023 was 78.4 years (75.8 for males, 81.1 for females), with projections suggesting a slight increase or stabilization by 2025.
Analysis: Life expectancy has increased by about 10 years, a significant improvement driven by advances in medical care, vaccines, and public health. However, recent stagnation due to chronic diseases and socioeconomic factors slightly tempers the “far, far better” claim. Still, the increase is substantial.
Verdict: True, life expectancy is significantly better in 2025.
2. Square Footage of Housing per PersonClaim: Houses are much bigger, with fewer people per house, leading to more square footage per person in 2025.
Fact-Check:
1950s: In 1950, the average new single-family home was ~1,000–1,200 square feet, with an average household size of ~3.37 people, yielding ~300–350 square feet per person.
2025: In 2015, the average new home was 2,687 square feet, with a median of 2,467 square feet, and household size dropped to 2.54. This results in ~971–1,058 square feet per person. Recent data suggests a slight decline in home size (e.g., 2,386 square feet median in 2018), but the trend of larger homes persists.
Analysis: Square footage per person has nearly tripled due to larger homes and smaller households, strongly supporting the claim.
Verdict: True, square footage per person is far better in 2025.
3. Number of Bathrooms per Person in Each HouseClaim: Number of bathrooms per person is far better in 2025.
Fact-Check:
1950s: Data is sparse, but homes typically had 1–1.5 bathrooms, with an average household size of ~3.37, yielding ~0.3–0.4 bathrooms per person. Many homes, especially older or rural ones, lacked full bathrooms.
2025: Modern homes often have 2–3 bathrooms, with new homes in 2015 averaging ~2.5 bathrooms for a household size of 2.54, yielding ~1 bathroom per person.
Analysis: The increase from ~0.3 to ~1 bathroom per person is a clear improvement, driven by larger homes and modern design standards.
Verdict: True, bathrooms per person are far better in 2025.
4. Percentage of Homes with Air ConditioningClaim: Percentage of homes with air conditioning is far better in 2025.
Fact-Check:
1950s: In the 1950s, air conditioning was a luxury; fewer than 10% of homes had it, with ~50% of new homes by the mid-1970s having AC.
2025: By 2015, 93% of new homes had central air conditioning, and ~87% of all U.S. households had some form of AC (central or window units) by 2020. This percentage likely increased slightly by 2025.
Analysis: The rise from <10% to ~90% is a dramatic improvement, making this claim accurate.
Verdict: True, the percentage of homes with air conditioning is far better in 2025.
5. Number of Dental Cavities for the Average 18-Year-OldClaim: Number of dental cavities for the average 18-year-old is far better in 2025.
Fact-Check:
1950s: Limited data exists, but dental care was less advanced, with minimal fluoridation and poorer oral hygiene practices. Studies suggest 18-year-olds had ~4–7 cavities on average, with higher rates of untreated decay.
2025: By 2011–2016, CDC data showed ~1.5–2 cavities (decayed, missing, or filled teeth) for adolescents aged 12–19, with fluoridated water, better dental care, and sealants reducing decay rates. This trend likely holds or improved slightly by 2025.
Analysis: A reduction from ~4–7 to ~1.5–2 cavities is a significant improvement, supporting the claim.
Verdict: True, dental cavities for 18-year-olds are far better in 2025.
6. Percentage of the Population Vaccinated Against Polio and MeaslesClaim: Percentage of the population vaccinated against polio and measles is far better in 2025.
Fact-Check:
1950s: Polio vaccine was introduced in 1955, with ~50% of children vaccinated by the late 1950s. Measles vaccine wasn’t available until 1963, so 0% were vaccinated in the 1950s.
2025: By 2020, ~93% of U.S. children (19–35 months) were vaccinated against polio, and ~92% against measles (MMR). Adult vaccination rates are lower but still significant. Rates may have slightly declined due to vaccine hesitancy but remain high.
Analysis: The jump from ~50% (polio) and 0% (measles) to ~92–93% is a massive improvement.
Verdict: True, vaccination rates for polio and measles are far better in 2025.
7. Percentage of the Population with Indoor PlumbingClaim: Percentage with indoor plumbing is far better in 2025.
Fact-Check:
1950s: In 1950, ~85% of U.S. homes had indoor plumbing, with rural areas lagging (some as low as 50%).
2025: By 2020, >99% of U.S. homes had indoor plumbing, with near-universal access in urban and rural areas.
Analysis: The increase from ~85% to >99% is significant, though the 1950s baseline was already relatively high.
Verdict: True, but the “far, far better” claim is slightly exaggerated due to the high baseline in the 1950s.
8. Percentage of the Population that Takes a Daily ShowerClaim: Percentage taking a daily shower is far better in 2025.
Fact-Check:
1950s: Limited data, but daily showering was less common due to fewer bathrooms, cultural norms (weekly baths common), and water access issues in rural areas. Estimates suggest ~20–30% showered daily.
2025: Surveys (e.g., 2020 YouGov) indicate ~60–70% of Americans shower daily, driven by more bathrooms, better plumbing, and changing hygiene norms.
Analysis: The increase from ~20–30% to ~60–70% is notable, supporting the claim, though cultural factors influence showering habits.
Verdict: True, daily showering is significantly better in 2025.
9. Being Able to Watch Any Movie Whenever You WantClaim: Ability to watch any movie whenever you want is far better in 2025.
Fact-Check:
1950s: Movie access was limited to theaters, with ~4–5 billion annual theater admissions. Home viewing was rare, with no VCRs or streaming.
2025: Streaming services (Netflix, Disney+, etc.) allow instant access to millions of movies. Over 80% of U.S. households have streaming subscriptions, and physical media (DVDs, Blu-rays) are widely available.
Analysis: The shift from theater-only to on-demand streaming is a revolutionary improvement.
Verdict: True, movie-watching availability is far better in 2025.
10. Size of Average TV ScreenClaim: Size of the average TV screen is far better in 2025.
Fact-Check:
1950s: TVs were ~12–20 inches (diagonal), with small, bulky CRT screens.
2025: Average TV screen size is ~50–55 inches, with some households having 65–85-inch screens, driven by affordable flat-screen technology.
Analysis: The increase from ~12–20 inches to ~50–55 inches is a dramatic improvement in size and quality.
Verdict: True, TV screen size is far better in 2025.
11. Percentage of the Population that Owns a Color TVClaim: Percentage owning a color TV is far better in 2025.
Fact-Check:
1950s: Color TVs were introduced in 1954, but only ~1% of households had them by 1959 due to high costs.
2025: Virtually 100% of TV-owning households (~95% of all households) have color TVs, with modern TVs exclusively in color.
Analysis: The rise from ~1% to ~95% is a clear improvement.
Verdict: True, color TV ownership is far better in 2025.
12. Percentage of the Population Working in Air-Conditioned OfficesClaim: Percentage working at desks in air-conditioned offices, rather than manual labor in the sun, is far better in 2025.
Fact-Check:
1950s: ~30% of jobs were in manufacturing, agriculture, or construction, often outdoors or in non-air-conditioned spaces. Office jobs were ~15–20%, with limited AC (est. <20% of offices).
2025: ~80% of jobs are in service or office-based sectors, with >90% of offices air-conditioned. Manual labor jobs are <10% of the workforce.
Analysis: The shift to office work and near-universal office AC strongly supports the claim.
Verdict: True, the percentage working in air-conditioned offices is far better in 2025.
Summary
All claims are true, with most showing dramatic improvements that justify the “far, far better” description. The only slight caveat is indoor plumbing, where the 1950s baseline (~85%) was already high, making the improvement to >99% significant but less “far, far” than others. Advances in healthcare, housing, technology, and work conditions have driven these changes, though socioeconomic disparities and recent health trends (e.g., obesity) warrant consideration.
If you’d like further details or specific data for any point, let me know!

I asked Grok: “How much would an iPhone cost if all of the raw materials and ores, mining, refining, extraction, processing, design, programming, manufacturing, assembly, labor, and all other factors were done 100% entirely and exclusively in the United States?”
By Daniel Alman (aka Dan from Squirrel Hill)
April 10, 2025
I asked Grok: “How much would an iPhone cost if all of the raw materials and ores, mining, refining, extraction, processing, design, programming, manufacturing, assembly, labor, and all other factors were done 100% entirely and exclusively in the United States?”
This is the answer that it gave:
Estimating the cost of an iPhone if every aspect—raw materials, mining, refining, extraction, processing, design, programming, manufacturing, assembly, labor, and all other factors—were done 100% in the United States is a complex task. It requires considering a wide range of variables, many of which depend on assumptions about supply chain restructuring, labor costs, infrastructure development, and economic feasibility. While precise figures are unavailable due to the speculative nature of such a scenario, I can provide a reasoned estimate based on available data and expert analyses.
Currently, an iPhone’s production cost (bill of materials plus assembly) ranges from approximately $400 to $558, depending on the model (e.g., iPhone 15 Pro Max costs around $558). This reflects manufacturing primarily in China, where labor costs are low (averaging $2–$10/hour), raw materials are sourced globally, and supply chains are optimized for scale and efficiency. Retail prices range from $799 to $1,499, incorporating research and development (R&D), software, marketing, and Apple’s profit margin (typically 60–62%).
Moving all production to the U.S. would significantly increase costs due to several factors:
1) Raw Materials and Mining: iPhones contain about 75 elements, including rare earths (e.g., neodymium, dysprosium), aluminum, gold, and silicon. The U.S. lacks domestic sources for many of these. For instance, China supplies 85% of global rare earths, and there are no bauxite mines for aluminum in the U.S. Establishing new mines and refining facilities would take years and billions in investment, driving up costs. Extracting and processing these materials domestically could increase raw material costs by 2–3 times due to higher environmental regulations, labor costs, and initial capital outlays. Current component costs (around $400–$500) might rise to $800–$1,500.
2) Labor Costs: U.S. manufacturing wages average $22–$30/hour, compared to $2–$10/hour in China. Assembly alone, currently estimated at $4–$10 per unit, could rise to $30–$112 per unit, depending on hours worked (e.g., 7–8 hours at U.S. rates). Total labor costs across mining, refining, and manufacturing could add hundreds more per unit, potentially $200–$500, given the need for skilled workers in a fully domestic supply chain.
3) Manufacturing and Infrastructure: The U.S. lacks the scale and expertise of China’s manufacturing hubs (e.g., Foxconn’s facilities). Building equivalent factories could cost billions, amortized over fewer units initially due to limited capacity. Analysts estimate this could add $50–$100 per unit in overhead. Automation might offset some labor costs, but the upfront investment would still elevate prices.
4) Design and Programming: Apple’s R&D and software development are already U.S.-based, costing billions annually (e.g., $18.75 billion in 2020). These fixed costs, spread across millions of units, wouldn’t change significantly per unit, but any expansion of domestic talent to replace overseas engineering could slightly increase expenses (e.g., 5–10% more, or $10–$20 per unit).
5) Scale and Supply Chain: China’s ecosystem allows for rapid, cost-efficient production (e.g., 500,000 iPhones daily). Replicating this in the U.S. would require decades and massive investment, reducing economies of scale. Some estimates suggest production might drop from hundreds of millions to single-digit millions annually, pushing per-unit costs higher. Extreme scenarios propose costs of $30,000–$100,000 if supply chains collapse and output shrinks drastically, though this assumes near-total inefficiency.
Combining these factors, a realistic middle-ground estimate emerges:
Raw materials and processing: $800–$1,500 (up from $400–$500).
Labor (mining, refining, assembly): $200–$500 (up from $10–$50).
Manufacturing overhead: $50–$100.
Design/programming: $10–$20 increase.
Total production cost: $1,060–$2,120 per unit.
With Apple’s current profit margins (e.g., 60%), retail prices could range from $1,700 to $3,400. However, some analysts suggest costs could climb higher—$2,400–$3,500 per unit—if supply chain inefficiencies persist, pushing retail prices to $4,000 or more. Extreme estimates of $30,000+ arise from scenarios where production scales down dramatically (e.g., to a few million units), but this seems unlikely given Apple’s ability to adapt.
If AI does to manufactured goods the same thing that Moore’s Law did to computer memory, then poor people will live in 5,000 square foot mansions, rich people will live in 1 million square foot palaces, and the woke, radical left will still complain about income inequality.

Israel Proves the Desalination Era Is Here: One of the driest countries on Earth now makes more freshwater than it needs
By Rowan Jacobsen
July 29, 2016
Ten miles south of Tel Aviv, I stand on a catwalk over two concrete reservoirs the size of football fields and watch water pour into them from a massive pipe emerging from the sand. The pipe is so large I could walk through it standing upright, were it not full of Mediterranean seawater pumped from an intake a mile offshore.
“Now, that’s a pump!” Edo Bar-Zeev shouts to me over the din of the motors, grinning with undisguised awe at the scene before us. The reservoirs beneath us contain several feet of sand through which the seawater filters before making its way to a vast metal hangar, where it is transformed into enough drinking water to supply 1.5 million people.
We are standing above the new Sorek desalination plant, the largest reverse-osmosis desal facility in the world, and we are staring at Israel’s salvation. Just a few years ago, in the depths of its worst drought in at least 900 years, Israel was running out of water. Now it has a surplus. That remarkable turnaround was accomplished through national campaigns to conserve and reuse Israel’s meager water resources, but the biggest impact came from a new wave of desalination plants.
Bar-Zeev, who recently joined Israel’s Zuckerberg Institute for Water Research after completing his postdoc work at Yale University, is an expert on biofouling, which has always been an Achilles’ heel of desalination and one of the reasons it has been considered a last resort. Desal works by pushing saltwater into membranes containing microscopic pores. The water gets through, while the larger salt molecules are left behind. But microorganisms in seawater quickly colonize the membranes and block the pores, and controlling them requires periodic costly and chemical-intensive cleaning. But Bar-Zeev and colleagues developed a chemical-free system using porous lava stone to capture the microorganisms before they reach the membranes. It’s just one of many breakthroughs in membrane technology that have made desalination much more efficient. Israel now gets 55 percent of its domestic water from desalination, and that has helped to turn one of the world’s driest countries into the unlikeliest of water giants.
Driven by necessity, Israel is learning to squeeze more out of a drop of water than any country on Earth, and much of that learning is happening at the Zuckerberg Institute, where researchers have pioneered new techniques in drip irrigation, water treatment and desalination. They have developed resilient well systems for African villages and biological digesters than can halve the water usage of most homes.
The institute’s original mission was to improve life in Israel’s bone-dry Negev Desert, but the lessons look increasingly applicable to the entire Fertile Crescent. “The Middle East is drying up,” says Osnat Gillor, a professor at the Zuckerberg Institute who studies the use of recycled wastewater on crops. “The only country that isn’t suffering acute water stress is Israel.”
That water stress has been a major factor in the turmoil tearing apart the Middle East, but Bar-Zeev believes that Israel’s solutions can help its parched neighbors, too — and in the process, bring together old enemies in common cause.
Bar-Zeev acknowledges that water will likely be a source of conflict in the Middle East in the future. “But I believe water can be a bridge, through joint ventures,” he says. “And one of those ventures is desalination.”
Driven to Desperation
In 2008, Israel teetered on the edge of catastrophe. A decade-long drought had scorched the Fertile Crescent, and Israel’s largest source of freshwater, the Sea of Galilee, had dropped to within inches of the “black line” at which irreversible salt infiltration would flood the lake and ruin it forever. Water restrictions were imposed, and many farmers lost a year’s crops.
Their counterparts in Syria fared much worse. As the drought intensified and the water table plunged, Syria’s farmers chased it, drilling wells 100, 200, then 500 meters (300, 700, then 1,600 feet) down in a literal race to the bottom. Eventually, the wells ran dry and Syria’s farmland collapsed in an epic dust storm. More than a million farmers joined massive shantytowns on the outskirts of Aleppo, Homs, Damascus and other cities in a futile attempt to find work and purpose.
And that, according to the authors of “Climate Change in the Fertile Crescent and Implications of the Recent Syrian Drought,” a 2015 paper in the Proceedings of the National Academy of Sciences, was the tinder that burned Syria to the ground. “The rapidly growing urban peripheries of Syria,” they wrote, “marked by illegal settlements, overcrowding, poor infrastructure, unemployment, and crime, were neglected by the Assad government and became the heart of the developing unrest.”
Similar stories are playing out across the Middle East, where drought and agricultural collapse have produced a lost generation with no prospects and simmering resentments. Iran, Iraq and Jordan all face water catastrophes. Water is driving the entire region to desperate acts.
More Water Than Needs
Except Israel. Amazingly, Israel has more water than it needs. The turnaround started in 2007, when low-flow toilets and showerheads were installed nationwide and the national water authority built innovative water treatment systems that recapture 86 percent of the water that goes down the drain and use it for irrigation — vastly more than the second-most-efficient country in the world, Spain, which recycles 19 percent.
But even with those measures, Israel still needed about 1.9 billion cubic meters (2.5 billion cubic yards) of freshwater per year and was getting just 1.4 billion cubic meters (1.8 billion cubic yards) from natural sources. That 500-million-cubic-meter (650-million-cubic-yard) shortfall was why the Sea of Galilee was draining like an unplugged tub and why the country was about to lose its farms.
Enter desalination. The Ashkelon plant, in 2005, provided 127 million cubic meters (166 million cubic yards) of water. Hadera, in 2009, put out another 140 million cubic meters (183 million cubic yards). And now Sorek, 150 million cubic meters (196 million cubic yards). All told, desal plants can provide some 600 million cubic meters (785 million cubic yards) of water a year, and more are on the way.
The Sea of Galilee is fuller. Israel’s farms are thriving. And the country faces a previously unfathomable question: What to do with its extra water?
Water Diplomacy
Inside Sorek, 50,000 membranes enclosed in vertical white cylinders, each 4 feet high and 16 inches wide, are whirring like jet engines. The whole thing feels like a throbbing spaceship about to blast off. The cylinders contain sheets of plastic membranes wrapped around a central pipe, and the membranes are stippled with pores less than a hundredth the diameter of a human hair. Water shoots into the cylinders at a pressure of 70 atmospheres and is pushed through the membranes, while the remaining brine is returned to the sea.
Desalination used to be an expensive energy hog, but the kind of advanced technologies being employed at Sorek have been a game changer. Water produced by desalination costs just a third of what it did in the 1990s. Sorek can produce a thousand liters of drinking water for 58 cents. Israeli households pay about US$30 a month for their water — similar to households in most U.S. cities, and far less than Las Vegas (US$47) or Los Angeles (US$58).
The International Desalination Association claims that 300 million people get water from desalination, and that number is quickly rising. IDE, the Israeli company that built Ashkelon, Hadera and Sorek, recently finished the Carlsbad desalination plant in Southern California, a close cousin of its Israel plants, and it has many more in the works. Worldwide, the equivalent of six additional Sorek plants are coming online every year. The desalination era is here.
What excites Bar-Zeev the most is the opportunity for water diplomacy. Israel supplies the West Bank with water, as required by the 1995 Oslo II Accords, but the Palestinians still receive far less than they need. Water has been entangled with other negotiations in the ill-fated peace process, but now that more is at hand, many observers see the opportunity to depoliticize it. Bar-Zeev has ambitious plans for a Water Knows No Boundaries conference in 2018, which will bring together water scientists from Egypt, Turkey, Jordan, Israel, the West Bank and Gaza for a meeting of the minds.
Even more ambitious is the US$900 million Red Sea–Dead Sea Canal, a joint venture between Israel and Jordan to build a large desalination plant on the Red Sea, where they share a border, and divide the water among Israelis, Jordanians and the Palestinians. The brine discharge from the plant will be piped 100 miles north through Jordan to replenish the Dead Sea, which has been dropping a meter per year since the two countries began diverting the only river that feeds it in the 1960s. By 2020, these old foes will be drinking from the same tap.
On the far end of the Sorek plant, Bar-Zeev and I get to share a tap as well. Branching off from the main line where the Sorek water enters the Israeli grid is a simple spigot, a paper cup dispenser beside it. I open the tap and drink cup after cup of what was the Mediterranean Sea 40 minutes ago. It tastes cold, clear and miraculous.
The contrasts couldn’t be starker. A few miles from here, water disappeared and civilization crumbled. Here, a galvanized civilization created water from nothingness. As Bar-Zeev and I drink deep, and the climate sizzles, I wonder which of these stories will be the exception, and which the rule.

Why do millions of Indians defecate in the open?
By Shannti Dinnoo
June 17, 2014
It’s early morning and local commuters are queuing up for tickets at the Kirti Nagar railway station in the Indian capital, Delhi.
Along the tracks, another crowd is gathering – each person on his own, separated by a modest distance. They are among the 48% of Indians who do not have access to proper sanitation.
Coming from a slum close-by, they squat among the few trees and bushes along the railway tracks and defecate in the open.
To many, this is a daily morning ritual despite the hazards of contracting diseases such as diarrhoea and hepatitis.
It can be even more hazardous for women since each time a woman uses the outdoors to relieve herself, she faces a danger of sexual assault.
Recently two teenage girls from the state of Uttar Pradesh were gang-raped and found hanging from a tree after they left their village home to go to the toilet. Their house, like hundreds of millions of others in the country, did not have any facilities.
‘No privacy’
A new World Health Organisation (WHO) report says more than half a billion people in India still “continue to defecate in gutters, behind bushes or in open water bodies, with no dignity or privacy”.
Access to sanitation is a challenge that India’s politicians want to tackle – both the Congress and the Bharatiya Janata Party (BJP) promised to put an end to open defecation in their 2014 general election manifestos.
During his campaign, Narendra Modi, BJP’s newly-elected prime minister, promised: “Toilets first, temples later”.
And former rural development minister Jairam Ramesh of the Congress party had stressed that “practicing good hygiene is as important as performing good puja” (act of worship in Hinduism).
India’s government offers cash incentives to subsidise construction of toilets. It has also initiated hygiene and sanitation awareness campaigns, such as the “No Toilet, No Bride” slogan launched in the state of Haryana in 2005, urging brides to reject a groom if he did not have a lavatory at home.
The Gates Foundation too has offered grants to create latrines that are not connected to water, sewer or electricity and to improve the treatment of human waste.
‘Lack of focus’
The exhibits at a recent “toilet fair” organised by the Foundation in Delhi included a lavatory with a photovoltaic roof-top that powers a reactor breaking down excrements into fertiliser, and another one which came equipped with an automatic sterilisation system and a generator turning the moisture into water.
Apart from poverty and lack of lavatories, one of the reasons often cited to explain open defecation in India is the ingrained cultural norm making the practice socially accepted in some parts of the society.
“Just building toilets is not going to solve the problem, because open defecation is a practice acquired from the time you learn how to walk. When you grow up in an environment where everyone does it, even if later in life you have access to proper sanitation, you will revert back to it,” says Sue Coates, chief of Wash (water, sanitation and hygiene) at Unicef.
India will be free of open defecation only when “every Indian household, every village, every part of Indian society will accept the need to use toilets and commit to do so”, she says.
Professor at the Centre for Environmental Planning and Technology Meera Mehta says the strategies implemented so far may not have the expected impact because of a “lack of focus”.
“With the right policies and political attention, India can be free from open defecation within 10 years.

Ethiopia has chosen to greatly increase its use of technology and its standard of living.
By Daniel Alman (aka Dan from Squirrel Hill)
June 16, 2024
Ethiopia has chosen to greatly increase its use of technology and its standard of living.
The Ethiopia of today is absolutely nothing like the Ethiopia that people my age (I’m 53) saw on TV when we were growing up.
Back then, the news blamed Ethiopia’s famines on drought.
Now, this video says that during several recent droughts, there was no famine, and that was because of the choices that they made regarding irrigation, modern farming methods, and other advances in technology.
The same video also shows Ethiopians manufacturing clothing for export to rich countries, and they pointed out that Ethiopia is currently at the approximate level of development than China was at one generation ago.
I totally support these tremendous improvements.
https://www.youtube.com/watch?v=7qI711c03W8
I support using modern technology to give every person on earth a first world standard of living. The Asian tiger countries went from third world to first world in a very short period of time. Now Haiti is starting to do the same thing.

An experiment in Haiti is making once-arid lands fertile, and poor farmers into money-makers
By Jacqueline Charles
November 24, 2023




At first sight, the nearly four acres of farmland in this rural hamlet in northeast Haiti resembles more of a desert than a thriving agricultural experiment. The soil is brown and barren, battered by a lack of water and neglect.
But walk further inland and the seemingly lifeless terrain soon turns green: Cabbages and pumpkins rise out of the ground, papayas hang from trees and workers plant rows of hot peppers in the freshly plowed dirt as a generator hisses in the background.
A year ago, such a lush landscape was unimaginable for Fransik Monchèr, a farmer and father of seven who couldn’t even grow fiery habanero peppers because they quickly died.
All that changed the day a group of entrepreneurs decided to take a gamble to launch a socioeconomic experiment with the goal of answering a simple, but daunting question: What if a Haitian farmer, like Monchèr, had everything he needed to be a successful grower?
“That farmer who has the land, how do you get him to upgrade his way of production — and how do we recuperate that cost?” said Maxwell Marcelin, one of the entrepreneurs.
The quest for the answers has birthed an unusual partnership among four Port-au-Prince-based friends and entrepreneurs, and local farmers and agronomists in northern Haiti. Together, they are pushing locally grown peppers and sweet potatoes while also aiding farmers like Monchèr in transforming their sun-scorched land, restoring hope in the only livelihood they’ve known: agriculture.
Though 75% of Haiti’s population lives in rural areas, the country can’t feed itself. Nearly half of the population, 4.9 million people, are experiencing acute hunger, according to the United Nations. The blame, the U.N. says, can be placed on a number of factors, including poor irrigation systems, lack of capital, political instability and the intensifying gang violence that has spread beyond the capital of Port-au-Prince to rural areas.
In areas where gangs are not occupying farmland or distribution routes, small-scale farmers are fighting to grow crops with limited or no government support. Crops fail due to increasingly frequent and severe droughts and tropical storms, and higher-than-average temperatures.
None of it makes for a hopeful scenario where agriculture can once more become the driving economic force in the countryside.
“Everybody is locked into the idea that it can’t be done,” said Geoffrey Handal, the accounting and logistics expert in the friends’ group, who challenges such pessimism. “We have all of the qualified agronomists, we have all of the techniques needed, we have all of the land, we have all of the water, we have everything.”
While Haiti’s capital is overrun by gangs, in the north entrepreneurs and farmers are trying to focus on its economic potential. Peppers like these growing in a field in Paulette, Haiti are being grown for both the local and export markets.
‘Total despair’
When Marcelin first arrived at Monchèr’s farm in Limonade, the northeast city that is part of the Marihaboux Plain, he believed, like the farmer, that the land was unworkable.
“It was total despair,” Marcelin said, as a group of workers dig a hole on a dirt mound to plant habanero pepper trees. “He said every time he tried to plant, there was no rain and he would lose his harvest.”
Refusing to accept that the expansive plot was a wasteland, Marcelin and Handal began to think about how they could help. Monchèr not only needed seeds, but also financing. But most importantly, he needed a steady supply of water so he wouldn’t have to depend on rains.
“That’s the basis of agriculture. Otherwise it’s like you’re playing the lottery” waiting for rain, Marcelin said.
Farmers in Haiti have always struggled to make a living off their crops. But with help from a group of fellow Haitians, they are hoping to see their fortunes turn.
In Haiti, crops failed not just because of too little or too much rainfall, but also due to a lack of access to irrigation, even when water is available.
Just across the border 45 minutes away in the Dominican Republic farmers are successful, Marcelin said, so the issue is not the availability of water.
“The only thing is there is no investment on our side of the border to bring the water to the producers,” he said.
Armed with a study showing that there was indeed water under Monchèr’s arid land, the group sprang into action. Magalie Dresse, a well-known designer who works with women artisans, helped with financing. Handal, who is also experimenting with producing a bank of high-quality seedlings, provided the seeds. And Marcelin crunched the numbers. With a background in management economics, he wanted to show Monchèr that he could have a successful harvest and rely on it for income to feed his family.
“We provided him with a well, a submersible pump, a generator —a propane one because there is no gas,” Marcelin said. ”He has the support of one of our agronomists to help him on what to do and what not to do. We plowed his field.”
The contributions have not gone unnoticed. Since January, Monchèr has grown more than 2,000 pounds of habanero peppers in addition to other fruits and vegetables.
‘“They backed me up,” he said, flashing a smile and standing upright in his field. “I could not have accomplished this on my own. I could not have dug a well because I don’t have the means to do that.”
Whereas before he saw despair, he now sees hope.
“My children are starting to eat and I am beginning to make some money. If they tell me they are hungry, I can come here, grab two or three papayas and sell them to find money to buy food,” Monchèr said.
The group’s initial investment of about 480,000 gourdes — about $3,600 — is expected to bring Monchèr about $7,000 in sales, which he will make from selling his habanero peppers to AGRILOG/Ets JB Vital, S.A., the company that Marcelin and Handal use to export peppers to Miami.
A group of young entrepreneurs from Port-au-Prince is helping farmers in northern Haiti grow peppers. This variety, known as “Piman Bouk,” is among the peppers being developed in Paulette, Haiti.
“This is someone we’ve taken out of poverty when we gave him this opportunity,” Marcelin said.
“Because we invested in Fransik,” he adds, walking through the papaya trees, “we’ve created an oasis.”
From coffee to sweet potatoes
Growing up in a poverty-stricken Haiti as a member of a well-off family, Handal knew he was blessed, a feeling he’s wanted to share with others.
“I’ve always felt like every Haitian should have it and we should show the world this is how we live,” he said.
For 200 years, the Handal family exported coffee, once among the island’s most lucrative cash crops. But deforestation, natural disasters and the increasing need for coffee to be grown at higher elevations due to warming temperatures led to a rapid decline in coffee production. In 2008, Handal said the family was shipping 33 cargo containers of coffee beans each season.
A year later, before the devastating 2010 earthquake further decimated production, the family shipped only two containers “because we couldn’t find any coffee.”
Handel said that an investigation into the demise of Haiti’s coffee market led him to conclude that the family needed to invest in agricultural production. But more than a decade went by before he revisited the idea of exports, spending most of the time working in the family’s shipping business in Port-au-Prince.
“I realized the only two things we could export here would be, first of all, textiles and second, agriculture,” he said. He decided on the agriculture route as a way to boost his export volume. “It was purely a logistic play to see what could I do to get containers full of agriculture products out of Haiti.”
Then he met Marcelin, who pitched him on growing peppers and sweet potatoes, and helping farmers boost their harvest.
“The Dominican Republic is the same size, same economy as Haiti and there is no reason why we can’t reach that level of GDP,” Handal said. “If we do this right, if we invest properly in Haiti in 20 years, we can have 10% GDP growth every year. With that measure, this is how billionaires get made. This is how you create a real economy.”
Marcelin said he became interested in agriculture through the work of his wife, Kalinda Magloire. She is the founder of a clean cooking social enterprise known as SWITCH, which encourages Haitians to move away from charcoal in favor of propane.
One of the effects of Haiti’s declining agricultural sector is that when farmers can’t cultivate their land, they turn to cutting their trees down for charcoal production, which gives them about $400 every two years. For farmers to stop cutting trees to survive, said Marcelin, they need a path to production to get replace that revenue.
Cutting down the trees is “the easiest choice today because he doesn’t have money to invest, so he just lets the trees grow and then every two years, he sells them,” he said. “But if he had the financing, the know-how and access to market, he would have an alternative.
“When we were presenting clean cooking as an alternative, the question we were always presented with was, ‘What about the farmer who lives off charcoal?’ ” Marcelin adds. “This is why we started thinking about agriculture.”
Bringing back the Scotch bonnet, saving the Bouk
About 17 miles to the east of Limonade along National Highway 6 in the rural community of Paulette is the for-profit side of Marcelin and Handal’s vision. Together with the Peasant Movement for the Development of Paulette they are growing sweet potato and several varieties of pepper, including the high-in-demand “Piman Bouk,” whose first shipment arrived in Miami in April.
Despite the demand for Bouk, it is hard to find, said Handal, who has built a nursery to provide high quality pepper seeds.
“Today, even if a farmer wants to go plant Bouk, he won’t find quality seeds to do it,” Handal said.
The entrepreneurs also want to bring back production of the Caribbean Scotch bonnet, a variety of chili pepper. According to local lore, the Scotch bonnet, popular in Jamaica, was bountiful around Cap-Haïtien before the Haitian revolution but soon disappeared after Haiti won its independence from France in 1804.
The two are also working on exporting sweet potato, which for now is being sold on the local market as they continue to improve the yield for export to Europe with the help of agronomists from Honduras, who have expertise in growing the vegetable.
Geoffrey Handal is among four friends from Port-au-Prince, Haiti who have come together to launch a socioeconomic lab focused on helping farmers in northern Haiti access expertise and new techniques to grow crops.
To make the agricultural project work, the duo invested in a drip irrigation system, similar to what’s used in the Dominican Republic, and fertilizer. They also brought onboard interns from the nearby University of Limonade to assist and to learn.
The financial model, which Handal came up with, calls for the Paulette farmers to get 30% of sales.
“At the end of the day, when you look at the investment, it comes up to 50-50 in terms of profits,” Marcelin said. “In Paulette, it’s a Fransik Monchèr magnified. We created jobs but the profit sharing is for the whole organization…. Everyone who is in the ecosystem is making money.”
Handal also sees another important result.
“For me as long as the community is involved, that’s all you need,” he said.
The two also focus on finding creative ways to get around problems. After some of the habaneros and Piman Bouk ripened before they could be shipped out, Marcelin and Handal decided to go into the pepper sauce business.
With their next harvest less than 30 days away, they are hoping the sweet potatoes will be ready so they can be shipped out. If not, they will just continue to sell it locally.
The effort is “a bet that this country will not die, which is a bit of a leap of faith these days. But if it’s not going to die, it’s going to grow at some point,” Handal said. “And that’s why we invest.”

“UPDATE: I received several calls today from @Tesla Motors . They have been very accommodating so far, and are towing my car 2 hours away to Richmond to the service center at their own expense. Also, they delivered a loaner in the meantime.”
https://www.tiktok.com/@domnatishow/video/7181594117112122666
“UPDATE: Shocking interaction with Tesla service! They sent an estimate of nearly $2,000 and said my battery heater is broken. The notification on my screen said the battery is heating which was not true and their response regarding this false notification was very disappointing.”
https://www.tiktok.com/@domnatishow/video/7182837104857140522
Domenick Nati from Virginia, for instance, tried to charge his Tesla Model S ahead of Christmas but encountered some problems.
“I tried to charge it at my house, it won’t let me. So there’s no way to charge this battery or let it warm up in the cold,” Nati said in a TikTok video.
He then took the car to a Tesla Supercharger station and plugged it in but it failed to charge again.
The vehicle showed a message that the battery was heating and the car had a range of 19 miles at 1:11 pm.
“3:03, almost two hours later — battery is heating, 19 miles,” Nati read from the vehicle display with frustration later that day.
The temperature was reportedly around 19°F, or -7°C, at the time.
Nati’s video — titled “Tesla S will not charge in the cold. Stranded on Christmas Eve!” — has now amassed roughly 113,000 likes on TikTok.
I asked ChatGPT: “Does the transporter on Star Trek kill every person who uses it, and then manufacture an exact duplicate?”
I asked ChatGPT: “Does the transporter on Star Trek kill every person who uses it, and then manufacture an exact duplicate?”
This is the answer that it gave:
“No, the transporter on Star Trek does not kill every person who uses it, and then manufacture an exact duplicate. The transporter is a device used to teleport people and objects from one location to another. It works by breaking down the molecular structure of the subject and then reassembling it at the destination. The goal of the transporter is to safely transport the subject from one place to another, not to kill them and create a duplicate.”
“In the Star Trek franchise, the transporter is generally considered a safe and reliable technology, and it is widely used for transportation purposes. While there have been instances in which the transporter has malfunctioned or been used in unusual ways, leading to strange and sometimes dangerous consequences, these instances are few and far between.”
“It is important to remember that the Star Trek franchise is a work of fiction, and the depiction of the transporter and its effects on people and objects is not meant to be taken as a scientific explanation of how teleportation would actually work in the real world. The transporter is a science fiction device that is used to drive the story and create exciting and imaginative scenarios for the characters.”

There’s a “smart” phone app that tells you when your jar of peanut butter is empty. How dumb can people be?
By Daniel Alman (aka Dan from Squirrel Hill)
August 29, 2022
I’ve never actually owned a “smart” phone. And I guess this is one reason why.
There is now an app that tells your “smart” phone when your jar of peanut better is empty.
This article from the Pittsburgh Tribune-Review is from four years ago, but I just found about it now. It says:
Even though no one can see you eating peanut butter off a spoon in the middle of the night, the jar’s label might soon be “watching.”
Adrich, a Pittsburgh company that designs smart labels that could alert customers when they’re running low on their favorite products, just signed its first major deal to slap their innovation on products bound for consumers’ homes.
The labels will be able to track when and how much of a product people use. Sensors embedded in the labels can detect movement and also determine how much of a product remains, Aji said. Adrich then uses a proprietary algorithm to make sense of the data.
For example, during tests in which labels were on jars of peanut butter, Adrich found that people snacked on peanut butter at all hours of the day.
Companies can send coupons or other promotions when they sense a customer is about to run out of a product. Customers can learn when they should restock.
The labels — “almost like a mini-computer,” Aji said — contain a battery and sensors but are nearly as thin as a regular label. The label connects to a user’s smartphone through Bluetooth.
I’m 51 years old. I’ve been eating peanut butter ever since I was a child. And I’ve never, ever had trouble figuring out if the jar was empty.
And even when the jar is empty, well, I plan in advance, so I always have an extra jar (or a few, actually) because I always stock up on all of the non-perishable foods that I eat on a regular basis. That’s why homes have kitchen cabinets, shelves, and pantry closets. I have actually never, ever run out of peanut butter, soap, or toothpaste, because I always know that I’m always going to be using those things, so I always keep extra in my home.
Is there anyone who is so dumb that they need an app to tell them when their jar of peanut butter is empty?
How 1,500 Nuclear-Powered Water Desalination Plants Could Save The World From Desertification
How 1,500 Nuclear-Powered Water Desalination Plants Could Save The World From Desertification
By James Conca
July 14, 2019
About 20% of the world’s population has no access to safe drinking water, and this number will increase as the population continues to grow and global freshwater sources continue to decline. The worst-affected areas are the arid and semiarid regions of Asia, the Middle East and North Africa.
UNESCO has reported that the freshwater shortfall worldwide will rise to 500 trillion gallons/yr by 2025. They expect water wars to break out in the near-future. The World Economic Forum says that shortage of fresh water may be the primary global threat in the next decade.
But 500 trillion gallons/year only requires about 1,500 seawater desalination plants like the ones being built in California and Saudi Arabia. At a billion dollars a pop, that’s a lot cheaper than war and starvation.
Unfortunately, we presently desalinate only 10 trillion gallons/year worldwide.
As reported in the Tri-City Herald and NYTimes, stock exchange mutual funds have even formed surrounding water scarcity and have done quite well, like the AllianzGI Global Water Fund. This fund has averaged almost 10% since 2010 compared to under 6% for its average peer fund. These companies mainly deliver, test and clean drinking water.
In California, the MegaDrought, that ended in 2017 ran for five years, severely straining water supplies, agricultural needs and wildlife. It clarified the need to build new desalination plants like every other modern arid population in the world. Most of Abu Dhabi’s gas-fired power plants provide electricity to their huge desalination plants that deliver over a billion gallons of drinking water a day, at about 40¢/gallon. And it tastes good, too, I’ve tried it.
California needs 30 large desalination plants to deal with future megadroughts. They did recently build one in Carlsbad, but it’s not nearly enough.
Desalination technologies are capable of treating water from a wide variety of sources, including brackish groundwater, surface water, seawater, and domestic and industrial wastewater. While the wastewater from desalination is itself problematic, MIT has developed a process to turn it into useful products.
The two main types of desalination are:
– thermal desalination (using heat energy to separate the distillate from high salinity water), represented by Multiple Effect Distillation (MED), Multi-Stage Flash distillation (MSF) and Mechanical Vapor Compression (MVC), the latter primarily used to desalinate highly salty waters and industrial wastewater for industrial use, not necessarily for drinking.
– reverse osmosis (RO) membrane separation, which uses a membrane barrier and pumping energy to separate salts from the water. These are common in homes and businesses.
Electrical energy is used for membrane-based systems and thermal energy is used for distillation systems. Some hybrid plants combine both membrane and distillation.
Most desalination plants in the world use fossil fuels to power them, but it’s even better to power them with nuclear energy. The new fleet of Small Modular Nuclear Reactors (SMRs) are ideal as they produce both thermal energy and electrical energy without producing greenhouse gases.
But only 15 out of the thousands of desalination plants operating today worldwide are powered by nuclear. A small one is at the Canyon Diablo Nuclear Plant in California, slated to be closed soon. The plant could power several huge desalination plants for decades that could desalinate its own cooling water, removing the most commonly stated problem with the plant.
In contrast, all nuclear-powered naval vessels routinely use nuclear energy to desalinate seawater.
SMRs, like NuScale’s, allow places with smaller electrical grids and limited infrastructure to add new electrical and water capacity in small increments and allow countries to site them as needed at many distributed locations. NuScale’s small power module is in its last stages of licensing by the Nuclear Regulatory Commission and will be ready in only a few years.
NuScale’s small power modules are about 60 MW each and up to 12 of them can be put together to make a power plant up to 720 MW – a 12-pack. They use standard 17×17 PWR fuel assemblies, but only at half the height, with an average U235 enrichment of only 3.8%. A single NuScale nuclear power module is 76-feet tall and 15-feet in diameter, and sits in a plant covering 32 acres or only 0.05 square miles.
Refueling of any SMR does not require the nuclear plant to shut down. The small size and large surface area-to-volume ratio of the reactor core, that sits below ground in a super seismic-resistant heat sink, allows natural processes to cool it indefinitely in the case of complete power blackout, with no humans needed to intervene, no AC or DC power, no pumps, and no additional water for cooling.
This reactor cannot melt down.
Studies by Ingersoll and others show how nuclear power and desalination can be coupled, and how much it costs. They coupled a NuScale power plant with eight modules to each of the desalination technologies – Multiple Effect Distillation (MED) and Multi-Stage Flash distillation (MSF) with either high pressure (HP) steam taken before admission into the turbine, medium pressure (MP) steam taken from a controlled extraction of the turbine, and low pressure (LP) steam taken from the exhaust end of the turbine, and reverse osmosis (RO).
They sized the desalination plant to have a production capacity of 50 million gallons per day (190,000 m3/day) of drinking water, typical of a large municipal desalination plant like the Carlsbad Desalination Plant, and that can support a population of 300,000.
The table below summarizes their economic analysis. For drinking water, the NuScale-RO design is the cheapest and produces the most water per energy used, with LP-MED distillation a close second. Since a NuScale power plant will last at least 80 years, the payback is even better.
There are other technologies that have been, and are being, used as well, including the more economical water reuse. The City of Redlands in California is using a membrane bioreactor technology from GE that recycles over 6 million gallons/day of municipal wastewater.
Whatever technologies are selected, southern California needs to build the equivalent of 30 desalination plants the size of Carlsbad’s to produce over a billion gallons a day, solving most of the water problems of southern California. The Central Valley would need another 30 plants to deal with its agricultural needs as its groundwater is becoming increasingly salty.
Powered by SMRs, these plants would more than pay for themselves by their own revenue, although a small water tax would get them started faster.
California better get moving. It’s been a reasonable two years, but more MegaDroughts are on the way.
Amazon’s “smart” homes locked people out of their homes, and prevented their refrigerators from working
How Amazon Outage Left Smart Homes Not So Smart After All
By Isabella Steger
December 7, 2021
The outage at Amazon.com Inc.’s cloud-computing arm left thousands of people in the U.S. without working fridges, roombas and doorbells, highlighting just how reliant people have become on the company as the Internet of Things proliferates across homes.
The disruption, which began at about 10 a.m. Eastern time Tuesday, upended package deliveries, took down major streaming services, and prevented people from getting into Walt Disney Co.’s parks.
Affected Amazon services included the voice assistant Alexa and Ring smart-doorbell unit. Irate device users tweeted their frustrations to Ring’s official account, with many complaining that they spent time rebooting or reinstalling their apps and devices before finding out on Twitter that there was a general Amazon Web Services outage. Multiple Ring users even said they weren’t able to get into their homes without access to the phone app, which was down.
Others said they weren’t able to turn on their Christmas lights.
Smart lightbulbs stopped responding to voice commands, many people reported.
Basic household chores also become impossible for some.
The outage prompted people to reflect on the pitfalls of having a “smart” home that’s overly dependent on not only the internet, but one company in particular — while those with “dumb” homes gloated that their fridges and light switches were working just fine.
Several of the affected AWS operations were on the East Coast. AWS said about nine hours later that it had resolved the network device issues that led to the outage.
Germany’s phaseout of nuclear power is causing an increase in the use of fossil fuels, which is causing more than 1,100 additional deaths each year
This is a quote from a scientific paper on Germany’s phaseout of nuclear power:
“Put another way, the phase-out resulted in more than 1,100 additional deaths per year from increased concentrations of SO2, NOx, and PM. The increase in production from hard coal plants is again the key driver here, making up roughly 80% of the increase in mortality impacts.”
Source: Page 25 at this link https://www.nber.org/system/files/working_papers/w26598/w26598.pdf
Either the people who support this phaseout are extremely illiterate when it comes to science, or they are deliberately killing these people. I wonder which one it is.
