Why Design Now?: Hope Solar Tower


Why? Solar towers capture solar energy to heat air under an expansive collector zone. Based on the principle that heat rises, this air flows towards the center of the collector through electricity-generating turbines and up and out of the tower, like a chimney. When built, the tower will be about 750 meters high and could produce enough electricity to power approximately 500 households.
