Solar engines provide green energy
Parabolic Mirrors drive Stirling engines.

An unusual solar park opened in Arizona: Parabolic mirrors drive hot air engines. The classic way to create electric solar power is through photo voltaic solar cells.



The Tessera Solar power plant works with engines that only need hot air to work. The concept has been discovered in 1816 by the Scottish minister Robert Stirling.



Tessera Solar uses parabolic mirrors that centralize sun rays on the hot air engine. Each engine can generate 25 kilowatts of energy. The whole park contains sixty of these plants.

Perhaps something for Ambergris Caye?
