Pouring Saltwater Over Graphene Generates Electricity

A team of Chinese scientists did an impossible-sounding thing. They created electricity simply by dragging a droplet of saltwater across a layer of graphene. No big fires, no greenhouse gases, no fuss. They created energy with just a miracle material and one of the most plentiful substances on Earth. » 4/15/14 11:15am Tuesday 11:15am

Moss-Covered Table Uses Photosynthesis To Power an FM Radio

As an electricity source, what could be greener than plants? That's the idea behind this rig, the world's first system that powers an FM radio using nothing more than the photosynthetic powers of moss. And creators Fabienne Felder and Dr. Paolo Bombelli are just getting started. » 3/12/14 3:20pm 3/12/14 3:20pm

The Batteries of the Future Could Be Powered By Rhubarb

Building the perfect battery is a hard problem. Batteries either too inefficient or too expensive or too unstable to power the renewable gadgets of the future. But a team of Harvard scientists just built a new kind of battery with a molecule found in food, and it could solve these problems. » 1/10/14 11:03am 1/10/14 11:03am
