Recovered steel, Davå Power Plant, Umeå, Sweden,
September 16, 2006. Dåva converts household waste and biomass into hot water
for heating, cold water for cooling, and 15 megawatts of electricity. It is one
of the world's most efficient power plants. At first, they paid a firm to haul
away this scrap, and dump it. But almost
everything has value, and now they ship the steel to the Chinese! In a nation of smart people, this plant showcases
some of the very smartest ideas.
