I remember reading a lecture by Feynman where he discusses reversible computing and suggests that you can get processing down to insanely low power usage using those methods. I couldn't find a link to the lecture in question, but here is some recent research to give an overview - http://ercim-news.ercim.eu/en79/special/micropower-towards-low-power-microprocessors-with-reversible-computing http://ercim-news.ercim.eu/en79/special/micropower-towards-l...
