Hi kens, This is actually not powered by electricity but by the gradient of hydrogen ions between the inside and outside of the mitochondrial matrix... As jballanc says, and you say, this is awesomely cool though. I use this video http://www.youtube.com/watch?v=zOSyGTYCRFw to teach my future medical students the function of the ATPase - jballanc, I agree the mechanical aspect of ATP synthesis is awesome.
