☀️💧 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.
IN 2006, RESEARCHER CLEVE BACKSTER — THE MAN WHO INVENTED THE CIA'S LIE DETECTOR PROTOCOLS — PUBLISHED 36 YEARS OF EXPERIMENTS PROVING THAT PLANTS, BACTERIA, AND HUMAN CELLS IN PETRI DISHES RESPOND INSTANTANEOUSLY TO HUMAN THOUGHT AND EMOTION — EVEN AT DISTANCES OF HUNDREDS OF MILES. THE SIGNAL IS FASTER THAN LIGHT. IT DOES NOT DIMINISH WITH DISTANCE. IT IS NOT ELECTROMAGNETIC.
In 1966, Cleve Backster was the world's foremost expert on polygraph technology. He had developed the interrogation techniques used by the CIA, FBI, and U.S. military. He understood galvanic skin response — the electrical conductance of biological tissue — better than anyone alive.
One morning, on a whim, he attached polygraph electrodes to a Dracaena plant in his office. He watered it and watched the tracing. Then he thought: "I wonder what would happen if I threatened this plant." He decided to burn a leaf with a match.
The instant he formed the intention — before he moved, before he lit the match, before any ...
