A 40 storey concrete tower is the focus of the latest “weapon” in renewable energy. 600 mirrors (heliostat reflectors) focus the sun’s rays onto a receiver in the tower where the heat turns water into steam that powers giant turbines.
Creating currently 11 Megawatts (MW) of energy that can power 6,000 homes in it’s home of Seville, Spain, it is hoped it will eventually power 100 times that number. It can also still generate electricity for at least an hour after the sun goes down.
A good idea?
