An entrepreneur, Roger Davey is making an invention that takes advantage of the fact that heat rises. He wants to capture and control hot air to power cities. Davey wants to build a solar updraft tower. The tower would be 2,600 feet tall, in the Arizona desert. The tower would spin 32 turbines creating mechanical energy, which generates and converts to electricity.  The company he works for says he can create 200 megawatts of power. This would be enough to power 100,000 homes. This is different then solar power because it also works at night.
