Funneling the sun’s energy

MIT engineers propose a new way of harnessing photons for electricity, with the potential for capturing a wider spectrum of solar energy.

The quest to harness a broader spectrum of sunlight’s energy to produce electricity has taken a radically new turn, with the proposal of a “solar energy funnel” that takes advantage of materials under elastic strain.

“We’re trying to use elastic strains to produce unprecedented properties” … Continua a leggere su http://mitei.mit.edu
