Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink. Water contaminated with non-biological agents such as toxic chemicals or heavy metals require additional steps to make the water safe to drink.
Solar still built into a pit in the ground "Watercone" solar still. A solar still distills water with substances dissolved in it by using the heat of the Sun to evaporate water so that it may be cooled and collected, thereby purifying it. They are used in areas where drinking water is unavailable, so that clean water is obtained from dirty ...
The floating panel can turn contaminated water or polluted seawater into both drinking water and clean, hydrogen fuel. The device works off-grid so could prove useful in places with limited resources.
A Water pyramid or WaterPyramid is a village-scale solar still, designed to distill water using solar energy for remote communities without easy access to clean, fresh water. It provides a means whereby communities can produce potable drinking water from saline , brackish or polluted water sources.
Researchers have invented a solar-powered device capable of extracting several litres of water from thin air in a single day. The new self-sustaining technology could provide a lifeline for people ...
A Chinese-led international research team has created a "tree" that can generate clean drinking water.Drawing its energy entirely from the sun just like a real tree, the "water tree" has a root ...
