Isto promete!

200 vezes mais energia, dum Painel Solar?
A partir do painel de dia, e duma célula de combustível de noite?
É bom!

Vem isto duma reunião da American Chemical Society:

200-fold boost in fuel cell efficiency advances “personalized energy systems”
Note to journalists: Please report that this research was presented at a meeting of the American Chemical Society

BOSTON, Aug. 23, 2010 — The era of personalized energy systems — in which individual homes and small businesses produce their own energy for heating, cooling and powering cars — took another step toward reality today as scientists reported discovery of a powerful new catalyst that is a key element in such a system. They described the advance, which could help free homes and business from dependence on the electric company and the corner gasoline station, at the 240th National Meeting of the American Chemical Society, being held here this week.
“Our goal is to make each home its own power station,” said study leader Daniel Nocera, Ph.D. “We’re working toward development of ‘personalized’ energy units that can be manufactured, distributed and installed inexpensively. There certainly are major obstacles to be overcome — existing fuel cells and solar cells must be improved, for instance. Nevertheless, one can envision villages in India and Africa not long from now purchasing an affordable basic system.”
