Good cells are fairly klunky monocrystalline silicon PN junctions. They'd probably work fairly well after a million years if stored properly. >How about, even with a 100% conversion rate, how much energy could you >get from the light falling on a 200 cm2 device?

How much juice does a phasor use? ;) I have solar calculators that work in any light that people can reasonably work in, and they use tiny low-efficiency polysilicon cells. Just because 1000 years sounds like a lot to us, it's nothing to an inorganic crystal. John

Yeah, but I don't see too many alien Casio Scientific calculators on ST Voyager. I mean they pick up and ancient weapon on it fits a human hand, has a trigger that you can pull with a human finger, and can burn through solid rock in a matter of seconds. While Tuvoc stands in the back ground with his RPN solar calculator, that was laying in the ancient ruins, calculating the power density of the beam. :) > > Just because 1000 years sounds like a lot to us, it's nothing to an > inorganic crystal. True, but until one has actually made it a thousand years and is still operational, it is all speculation, educated speculation true. |
