Lowering Solid Oxide Fuel Cell Cost

Georgia Tech researchers have developed a new ceramic material that could help expand the applications for solid oxide fuel cells – devices that generate electricity directly from a wide range of liquid or gaseous fuels without the need to separate hydrogen.

A Natural Clean-Up Technology

Researchers at North Carolina State University are demonstrating that trees can be used to degrade or capture fuels that leak into soil and ground water. Through a process called phytoremediation, plants and trees remove pollutants from the environment or render them harmless.

Algae Blooms Broaden Battery Possibilities

Blooms of Cladophora algae may be troublesome, but they do have a positive side. Researchers at the Ångström Laboratory of Sweden's Uppsala University have discovered that the cellulose nanostructure of these algae can serve as an effective coating substrate for use in environmentally friendly batteries.

Tree Totally Powers Custom Circuit

Last year, MIT researchers found that plants generate a voltage of up to 200 millivolts when one electrode is placed in a plant and the other in the surrounding soil. A University of Washington team followed up on this research, and has run a custom circuit entirely off tree power.
