For the one in every eight souls around the world lacking access to pure drinking water, how about this: A solar-powered water purification system that spits out pure water, hydrogen and, just for kicks, electricity too.
Most people know about light emitting organisms such as jellyfishes, fireflies and mushrooms . Some time ago, genetic engineers transferred genes responsible for the luciferin and luciferase proteins into a tobacco plant. These firefly proteins were then manufactured by the tobacco plant, causing it to glow and emit light.
No, it's not a joke or a crazy awesome futuristic concept . It's real. Tata Steel Europe (formerly Corus) and Swansea University in Wales, UK are collaborating to develop a spray-on technology that would transform steel sheets into solar panels.
A low-cost water purification technique published in Current Protocols in Microbiology could help drastically reduce the incidence of waterborne disease in the developing world. The procedure, which uses seeds from the Moringa oleifera tree, can produce a 90.00% to 99.99% bacterial reduction in previously untreated water, and has been made free to download as part of access programs under John Wiley and Sons' Corporate Citizenship Initiative. A billion people across Asia, Africa, and Latin America are estimated to rely on untreated surface water sources for their daily water needs.
