IBM Research uses supercomputer tech to "harness the energy of 2,000 suns"
A collaboration of Swiss institutions, including IBM Research, has announced that it's developing a highly efficient, low-cost photovoltaic system that's capable of concentrating "the power of 2,000 suns." The collaboration claims that the system, which is targeted at dry regions such as southern Europe, Africa, the south west of North America, South America, and Australia, will have an overall efficiency of 80% -- and, miraculously, be able to provide a source of fresh water, too. Another supercomputer, Titan, will have the world's fastest storage.
