By Darren Quick
22:28 November 4, 2009 PST
Reports of new developments in the area of solar power are an almost daily event here at Gizmag. The main focus of research seems to be on improving the efficiency of solar cells, but others are working at developing an inexpensive method of locally storing the energy generated by solar systems. Because society relies on a continuous energy supply and solar energy is diurnal, storage systems are integral to what some see as an inevitable move towards the era of “personalized solar energy”, in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities.

Obama bets US$2.4 billion on battery-electric vehicles
By Loz Blain
03:29 August 7, 2009 PDT
Awesome news: battery technology is about to get a US$2.4 billion-dollar kick in the pants. US President Barack Obama has announced the single largest funds injection into battery development and electric/hybrid vehicle technology the world has ever seen. Obama's hope is that this huge chunk of stimulus funds will be enough to knock down the biggest wall standing between electric vehicles and the mainstream: the fact that current batteries are still too expensive, take too long to charge, and don't hold enough energy. If the move succeeds, it could put America right at the front of the electric car revolution - but at the least, it could help the next generation of iPhones last more than a day between charges.
