This is the latest from the non-stop idea factory of Bill Gross. This is a high-energy, low-cost solar concentrator that will fit on your roof.
How it works
Light strikes the aluminium-cladded surface, the photons ricochet off 25 mirrors arranged in a 5- by 5-foot square and converge in a shaft of light brighter than the sun at high noon. The tightly focused stream crashes into 100 square inches of silicon suspended over mirrors, sending a spray of electrons dancing down a copper wire. A CPU revs and tiny motors whir. As one, the mirrors adjust their positions ever so slightly. And the latest attempt at keeping pace with humanity’s epic appetite for energy begins another day of pulling power from the sky.
