This week a couple of important solar breakthroughs have surfaced in the news. Both IBM and Physicist Bram Hoex (and colleagues) have demonstrated two different solar breakthroughs worth noting. The IBM solar breakthrough involves using a thin liquid metal layer of gallium and indium that is cooled by a plate of copper. By use of solar concentrators that raise the sun’s rays by a factor of 10 and a cooling mechanism for the photovoltaic cells, IBM is able to produce the highest efficiency … more
