Or you can use the heat of that sunlight to boil water, and then drive a turbine with the resulting steam. These are both established technologies. But there is, in principle, a third way: use heat directly, without steam or turbines. In this case, unlike a standard solar cell (which is sensitive to some frequencies of light, but not others), almost all of the incident energy is available for conversion. Peter Bermel of the Massachusetts Institute of Technology and his colleagues have invented a way of concentrating the energy in the sun's rays without the need for mirrors. It is, quite literally, a suntrap. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
