Voltage Increases Observed in Closely Packed Nanowires
Posted in Batteries, Solar Power, Energy Efficiency, Test & Measurement, News, GDM on Thursday, 08 December 2011
Unexpected voltage increases of up to 25 percent in two barely separated nanowires have been observed at Sandia National Laboratories. Designers of next-generation devices using nanowires to deliver electric currents — including batteries and certain solar arrays — may need to make allowances for such surprise boosts.

Ongoing Power Performance Research to Advance Electromobility
Posted in Batteries, Electronics & Computers, Energy Storage, Energy Efficiency, Energy, Transportation, News, GDM on Wednesday, 26 October 2011
The AutoTram® is as long as a streetcar and as maneuverable as a bus. It doesn’t need rails or overhead lines because it rolls on rubber tires and simply follows white lines on the street. In “Fraunhofer’s System Research for Electromobility,” the AutoTram® was used as an experimental platform. It was a component of the research collaboration of more than 30 of Germany's Fraunhofer institutes.
