Lightweight, Solar-Powered Generator

An Office of Naval Research (ONR)-funded solar generator has recently entered full production, with several systems already in the field. The Ground Renewable Expeditionary ENergy System (GREENS) is a portable, 300-watt, hybrid battery generator that uses the sun to produce electric currents.

Self-Healing Electronics Could Reduce Waste

When one circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss. University of Illinois engineers have now developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink.

Voltage Increases Observed in Closely Packed Nanowires

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

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.
