isn't that the plot of an old twilight zone episode? a woman is offered cash if she presses a button and kills a human being - someone "she doesn't know", and in the end she presses it and as the guy leaves she asks him what will happen now and he says he will give the button to someone else... someone "she doesnt know" dah dah dummmm. lol
the australian companies Dyesol and Origin Energy have done something similar. I am unsure of the difference as I am not scientific minded. I just know that it is paper thin and solar power. I don't think they are ready for mass production however.
