Solar chimneys could be the way forward

“A solar chimney power plant consists of a circular transparent collector raised a certain height from the ground, with a chimney at the collector centre. A single turbine or multiple turbines are located at or near the base of the chimney and are connected to an electric generator or generators. Radiation from the sun penetrates the collector and strikes the ground surface beneath, which is heated and in turn heats the adjacent air, causing it to rise. The warm rising air is trapped underneath the collector, but rises up into the central chimney, causing the air under the collector to be channelled into the chimney as well. The air flowing into the chimney drives the turbine or turbines which subsequently generates electricity.”
