☀️💧 Solar-powered desalination system is cheap enough to solve the world’s drinking water shortage
MIT and Shanghai researchers created a solar desalination system that transforms seawater into affordable drinking water, using only sunlight.
Engineers at MIT and Shanghai Jiao Tong University in China are working on an innovative solar-powered desalination system to convert seawater into drinkable water. The system aims to provide clean water more affordably than tap water.
In a study published in Joule, the researchers outlined their design for a passive desalination device. This system uses natural sunlight to heat seawater, promoting evaporation and leaving salt behind. The water vapor is then condensed into pure drinking water.
What sets this system apart from others is its ability to avoid clogging by keeping the salt in motion. Salt accumulation can be a major issue in desalination systems, but the team’s design ensures the salt is continuously flushed out instead of building up and blocking the system.
The potential impact is significant. The researchers estimate that a device about the size of a small suitcase could generate 4 to 6 liters of drinkable water per hour. This small-scale system could supply enough water to meet the needs of a small family. At this scale, it could even provide cheaper water than tap water, according to Lenan Zhang, a research scientist at MIT.
Police in Winona Minnesota are stunned after every single one of their Flock cameras were suddenly removed in a single night.
According to the police department, all 8 of the town's cameras were cut down and hauled away.
Police are asking for the public's help to identify the individual, but the public has been responding with comments such as:
"The Flock cameras tore themselves down"
"Whoever did it, was fishing with me"
"Whoever it was, was at Bible study with me"

Nearly 20,000 people are publicly vouching for a man accused of cutting down Flock cameras in a small West Virginia town.
People commented:
"He was saving my neighbor's dog from a fire all day, couldn't be him."
"This man is innocent. I saw him serving at a soup kitchen."
-"Couldn't be him. He was helping me replace the roof on a homeless shelter."
The man, Wesley Jackson, has pleaded Not Guilty.

US diesel crack surpasses $100 a barrel for the first time on supply disruptions
... and the supply of refined fuels is already nearly exhausted. A hard landing is visible ahead, for farmers, for trucking, and ... well, for everything that requires food (people) and energy (the entire economy).
These are very likely the final days of relative normalcy during which to prepare. Get ready.
🌾 🌍 🚜 JPMorgan warns a massive global food supply crisis could begin next year as fertilizer shortages tighten agricultural supply.
JPMorgan is the latest institutional research desk to warn that the next global food crisis may already be taking shape, driven by what its analysts describe as the "Five Ws": War, Weather, Warehousing, Water, and Waste.
In a new report titled Food Security Is National Security: A Compounding Storm, a team led by London-based senior global economist Nora Szentivanyi warned that disruptions around the Strait of Hormuz and the emergence of a potentially historic El Niño could weaken crop yields, constrain agricultural production, and keep food inflation elevated through the first half of 2027.
"Successive shocks since COVID have compounded, eroding food production capacity and keeping food price pressures elevated into 2027," Szentivanyi said, warning that "this is not a short-lived shock; it has reduced the likelihood of near-term disinflation, and the food ...
