Scientists have announced yesterday that a collaboration consisting of ETH Zurich, IBM Research, the Interstate University of Applied Sciences Buchs and Airlight Energy is to develop an affordable photovoltaic system capable of concentrating solar radiation 2,000 times and converting 80 percent of the incoming radiation into useful energy. The system can also provide desalinated water and cool air in sunny, remote locations where they are often in short supply.
