That new energy concept named a solar tower is able to generate enough electricity for 200,000 homes.In fact, this looking like a giant smokestack appurtenance would release no noxious fumes — just sun-heated air.
Some of these days was told that the demonstrated more than 20 years ago project has the basic design calls for solar collectors to warm the air near Earth’s surface in order to channel it up the tall central tower then. Turbines placed at the bottom make electricity from the updraft.
“It’s a combination chimney, windmill, greenhouse,” said Kim Forté of EnviroMission Limited in South Melbourne, Australia.
EnviroMission has designed a kilometer-high solar tower (0.62 miles) and is now looking at possible sites in the southwestern United States for first constructions.
