I've been reading and studying a lot about Solar Energy lately. There are hundreds of different ways that scientists and engineers are attempting to produce energy from the sun. One of the many technologies I head about is called Solar Thermal Power. If I understand it correctly, the unique idea is to collect the solar rays and heat water or a liquid that can be used as steam which will turn the turbines that produce electricity. It is different in that all the solar materials are used to concentrate the light onto one source and that source is then used to heat the water or liquid. This to me makes sense.
Any way, here is a good article that highlights the various plants that are being built around the world that are solar thermal energy plants.
