Help finding renewable energy power plant?

[a j h]

I would go to google and click on 'advance search'. Fill in some search criteria and the bottom text input box is "search within a site or domain" and type in wikipedia.com there. This way you can search the body of the articles. good luck!

Hello, a few weeks ago on wikipedia I found a type of power plant that generated power by using greenhouses at the base of a structure to generate heat, which would heat the air in the structure. This would cause the air to rise which on the way up would turn turbines in the structure. I have been trying to find it again but I haven't had any luck. Anyone know the name of the type of power plant.
