☀️💧 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.
🛢📈 — Reuters reports that oil is approaching $100 per barrel following the latest exchange of attacks between Americans and Iranians on oil tankers.
▶️The price of Brent crude has risen to $97.07 per barrel, while American WTI crude has risen to $92.28. In the past week, Brent has risen by 7.8%, while WTI has risen by nearly 10%.
▶️On Saturday, U.S. forces attacked three Iranian oil tankers, one of which was stationed near the island of Kharg, a key center for Iranian oil exports. In response, the Islamic Revolutionary Guard Corps announced attacks on three oil tankers in the Strait of Hormuz and three more U.S. ships.
▶️In this context, traffic through the Strait of Hormuz has sharply declined. Over the past 10 days, an average of only 10 cargo ships have transited the strait per day – the lowest level since May.
The WHO now states on its website:
Vaccination against COVID-19 can trigger multiple sclerosis through cross-reactive CD4+-T cells that recognize the spike protein of SARS-CoV-2 and myelin peptides.
In other words: Your own immune system destroys the nerve pathways and then attacks your brain and spinal cord.
