IBM Solar Collector Concentrates The Sun 2000 Times
They call a High Concentration Photo Voltaic Thermal (HCPVT) system that is capable of concentrating the power of the sun 2000 times.
The process they are using to capture sunlight also produces water. This water can be used for drinking water or air conditioning.
The scientist envision this system being capable of providing energy as well as clean drinking water to communities around the world.
“Each 1cmX1cm chip can convert 200-250 watts, on average, over a typical eight-hour day in a sunny region. In the HCPVT system, instead of heating a building, the 90 degree Celsius water will pass through a porous membrane distillation system where it is then vaporized and desalinated. Such a system could provide 30-40 liters of drinkable water per square meter of receiver area per day, while still generating electricity with a more than 25 percent yield or two kilowatts hours per day. A large installation would provide enough water for a small town.” (2)
