New solar energy tech helps clean medical equipment
A new technology uses solar energy to turn water into steam, which may have a major impact on sanitation in developing countries and could help with distilling contaminated water.
A new solar energy technology may be a game changer in developing countries. Using only solar power, and thus no electricity or fuel, the new technology can turn water into steam without having to boil a container of water. The technology could potentially be used to clean medical equipment or sanitize human waste.
The technology was featured in the keynote address during the National Meeting & Exposition of the American Chemical Society (ACS). Naomi Halas D. Sc. points out that almost a third of the world’s population lives without electricity, and that means devices like the autoclave, which steam-sanitizes medical equipment, can’t be used. That, in turn, forces doctors to use much more expensive and difficult to transport chemicals for disinfecting their tools.
Clean water is a luxury many can’t afford… but that might change
Halas, who comes from Rice University, explains how the new technology could help: “[The technology] is completely off-grid, uses sunlight as the energy source, is not that large, kills disease-causing microbes effectively and relatively quickly and is easy to operate. This is an incredibly promising technology.” Halas argues that along with medical equipment, the device (‘nano heater’) could be modified to clean human and animal waste, a major source of infection and disease in developing countries. It could also be used to distill dirty or salt water.
