Using Electricity to Generate Alternative Fuel
Posted in Batteries, Alternative Fuels, Greenhouse Gases, Energy Storage, Solar Power, News on Friday, 30 March 2012
Electrical energy generated by various methods can be difficult to store efficiently. Chemical batteries, hydraulic pumping, and water splitting suffer from low energy-density storage or incompatibility with current transportation infrastructure. UCLA researchers have demonstrated a method for storing electrical energy as chemical energy in higher alcohols, which can be used as liquid transportation fuels.

Self-Healing Electronics Could Reduce Waste
Posted in Batteries, Electronics, Recycling Technologies, News on Wednesday, 21 December 2011
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
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.
