Hybrid biological machines powered by bacteria - Scientists at the U.S. DOE Argonne National Laboratory and Northwestern University have produced tiny microgears with slanted spokes that get turned as the common aerobic bacteria Bacillus subtilis swim by them. The reaction is controlled by the addition/subtraction of oxygen. (GizMag Dec. 21, 2009)

New nano-material could lead to self-washing windows and solar panels - Researchers from Tel Aviv University have discovered a new nanomaterial that can repel dust and water and could provide a self-cleaning coating for windows or solar panels. The new material is made up of molecules of peptides that “grow” to resemble small forests of grass. The coating also acts as a super-capacitor, thereby possibly providing an energy boost to batteries. (GizMag December 3, 2009)

Harnessing waste heat to produce electricity - In experiments involving a new technology, thermal diodes, an MIT research team has been able to demonstrate efficiency as high as 40 percent of the Carnot Limit, with calculations showing that this new system could ultimately reach as much as 90 percent of that ceiling. See the team's paper, "
Quantum-coupled single-electron thermal to electric conversion scheme". (GizMag November 19, 2009)

New solar storage solution could be the key to home-brewed electricity - A new
paper by MIT professor Daniel Nocera describes the development of a practical, inexpensive storage system for achieving personalized solar energy. At its heart is an innovative catalyst that splits water molecules into oxygen and hydrogen that become fuel for producing electricity in a fuel cell. (GizMag Nov. 4, 2009)

OS:Human Hair Solar Panel by Milan Karki - Despite the heavy skepticism, after hearing of a group of teenage students from Nepal who claim to have replaced expensive doped silicon with human hair to produce a solar cell capable of generating 18W of electricity, curiosity got the better of
Gizmag's Paul Ridden, who contacted the inventor to find out more. (PESWiki Oct. 16, 2009)
