  •  Nano metal (none)
    Interesting article in New Scientist (10/22/05) talks about burning nano metal shavings that can be recharged to burn (oxidize) over and over again, release nearly no pollutants, and use cheap metals like iron.
    Chunks of metal such as iron, aluminium or boron are the thing... Turn them into powder with grains just nanometres across and the stuff becomes highly reactive. Ignite it, and it releases copious quantities of energy. With a modified engine and a tankful of metal, [Dave] Beach [of Oak Ridge] calculates that an average saloon car could travel three times as far as the equivalent petrol-powered vehicle. Better still, because of the way that this metal nano-fuel burns, it is almost completely non-polluting. That means no carbon dioxide, no dust, no soot and no nitrogen oxides. What's more, this fuel is fully rechargeable: treat your spent nanoparticles with a little hydrogen and the stuff can be burnt again and again. It could spell the start of a new iron age, and not just for cars. All kinds of engines, from domestic heating units to the turbines in power stations, could be adapted to burn metal.
