Globo Amazônia - Veja as últimas notícias e proteste contra queimadas e desmatamento Greenpeace USA (greenpeaceusa) The Copenhagen Diagnosis Thomas L. Friedman (NYTimesFriedman) Energy Tower: Power for 15 Earths? Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today. Not only that, it could also be used as a desalination device and may be able to reverse the effects of global warming. Those are pretty big claims, but the researchers from the Technion - Israel Institute of Science seem confident that the "Energy Tower" could be a major solution to the world's problems. They've been working on the concept since 1983, and together have spent more than 150 man-years researching, designing, testing, and analyzing. As project founder Professor Dan Zaslavsky explains, the Energy Tower works on the basic principle of convection: hot air rises and cold air falls. Any kind of water - from a sea or drainage ditch - would be added to the top of the tower. Because it relies on the sun for hot air, the Energy Tower is considered a type of solar power.
