The 3rd Way. Nanosolar Technology
Nanosolar Technology, the 3rd way to produce electricity from solar. ( Tek-THink )
This video was done by Professor Gang Chen of MIT. He is the director of solar solar conversion center and expert in nanoscale solar technology and the chair of the association of mechanical engineers.
In the video he explains several types of solar energy, with an emphasis on a widely acclaimed solar thermoelectric device developed by his lab has developed. Dr. Chen gives a fascinating demonstration of how the device works, and explains that such technology is very popular and inexpensive in Europe and China. How to convert the available energy from the sun , 100,000 Terrawatts into usable power for earth.
