Nanotube cuff is 'solar cell' for exhaust pipes - tech - 09 March 2010 - New Scientist: "The hot gases passing through a vehicle's exhaust could be tapped to generate power, using 'cuffs' made from a new carbon-nanotube-based material. The 'thermocell' produces electricity at a similar cost per watt as commercial solar cells."
