The technology, which was recently published in Nature Communications, is called Direct Air Electrolyser (DAE) and works by draining water directly from the air before then
6 · 3. Thermal energy storage. Thermal energy storage is used particularly in buildings and industrial processes. It involves storing excess energy – typically surplus energy from renewable sources, or waste heat – to be used later for heating, cooling or power generation. Liquids – such as water – or solid material - such as sand or rocks
Your electric dehumidifier at home ''produces'' very expensive water." The prototype, under conditions of 20-30 percent humidity, was able to pull 2.8 liters (3 quarts) of water from the air over a

Writing in the journal Nature Communications, researchers at UT Austin describe an experiment where
This allows water to be cleared from the gel in about 20–30 minutes — three to four times faster than previous iterations of his team''s hydrogel-based system, Yu says. This is still about

Researchers have designed an extreme-weather proven, hand-held device that can extract and convert water molecules from the air into drinkable water
Much like a paper towel absorbs water, its hybrid hydrogel absorbs water at night — when air is more humid and cooler — and stores it. The daytime sun that
MIT engineers have synthesized a new superabsorbent hydrogel infused with lithium chloride that can absorb an unprecedented amount of moisture, even in
It''s also smaller than the past MOF-powered harvester and can fit in a handbag. Despite the size change, the device is even more energy-efficient. It produced 200 grams of clean water per square meter of water
MIT engineers have synthesized a superabsorbent material that can soak up a record amount of moisture from the air, even in desert-like conditions. Pictured are the hydrogel discs swollen in water.
At 30% relative humidity, 1 g of the hydrogel needs 180 min to take in just 0.7 g of water. In comparison, 1 g of an aluminum-based MOF called MOF-303 needs just 3 to 10 min to bring in 0.4 g of
Researchers at MIT and elsewhere have significantly boosted the output from a system that can extract drinkable water directly from the air even in dry regions, using heat from the sun or another
A team of engineers at the University of Massachusetts Amherst has recently shown that nearly any material can be turned into a device that continuously
Scientists in Switzerland have designed a device that extracts water from the air and uses sunlight to turn it into hydrogen.
However, if paired with a clean energy source such as a solar panel array, the running, and carbon, costs for the machine can be made more reasonable. 3. FIshing for water with fog nets. Another
The device absorbs water from the atmosphere. Solar energy or heat that is harnessed from, for example, industrial processes are used to generate hot, humid
Polymer film could be used in artificial muscle and to power micro- and nanoelectronic devices. MIT engineers have created a new polymer film that can generate electricity by drawing on a ubiquitous source: water vapor. The new material changes its shape after absorbing tiny amounts of evaporated water, allowing it to repeatedly curl up
The new hydrogel is more efficient in its uptake and release of water thanks to its structure, which pairs two distinct segments: a network of sites that absorb
Now, scientists have come up with a new prototype device that can harvest water from humid air, before splitting it into hydrogen and oxygen. What''s more, it''s capable of
