One of the greatest things you can do as an industrial designer with earth-saving aspirations is to find a source of free or nearly-free energy. That’s what Luís Castanheira appears very much to have done here. This is Voltair, a wind power generator comprised of an array of fans set on the median of a highway, each of them turned by the air pushed past by the cars speeding by. The cars that’d be going by one way or another. Brilliant!
