I wonder if CEP had anything to do with this?
----------------------------------------Scientists from the University of Harvard (EE.UU.) created a silicone cable 200 times thinner than a hair and that is able to turn the energy solar into electricity, which will facilitate its use in the nanotechnology. The nanotechnology is the branch of the science that studies the matter concerning atoms and molecules. The metric unit is the nanometer, millionth of millimeter. This nano cable has 100 nanometers of diameter. The process, the cable has three layers, according to explained the scientists in an article published in the last edition of the scientific magazine Nature. When the light arrives at nano tube strikes its external layer and pushes some electrons of silicon, which have negative load, towards the most internal layer. This same process causes “holes” with positive charge in the external layer. Other electrons of the most internal layers get to positively occupy the space of those “loaded holes” and the process begins again. This movement of s-electrons what electricity generates. The generated amount is of 200 picowatts (picowatts is equivalent to the millionth part of a watt). Although it seems very little, Charles Leiber, one of the investigators, remembered that with the nanotechnology very small structures can be constructed that would work with relatively little electricity. “Nevertheless, to make something interesting many interconnected circuits will be required and is probable that then the energy needs yes vary”, explained Leiber. The most serious problem so far is to obtain a greater efficiency when transforming the solar energy into electricity. The experts indicated that while this nano tube turned 3% of the light into electricity, solar cells make the normal in a 25%. ![]() ---------------------------------------- [Edit 1 times, last edit by falconet at Oct 19, 2009 5:23:42 PM] |

That is 10 to -12 power, not 10 to -6 power. Cheers
