Subject: IBM Solar Collector to Breakthrough-Collects the Power of 2,000 Suns; Still Keeps it Cool Sun May 26, 2013 12:05 am
IBM states that the system would be just one-third the cost third of current comparable technologies. Now, that is an added bonus.
IBM claims that it would require only two percent of the Sahara's total area to supply the world's energy needs. The team designed the HCPVT system around a huge parabolic dish covered in mirror facets. A tracking system that moves along with the sun supports and controls the dish. Sunrays reflect off the mirror into receivers containing triple junction photovoltaic chips, each able to convert 200-250 watts over eight hours. Combined hundreds of the chips provide 25 kilowatts of electricity.
