” Project: Solar Tower Technology
-
Air is heated by solar radiation under a low circular glass roof open at the periphery; this and the natural ground below it form a hot air collector. In the middle of the roof is a vertical tower with large air inlets at its base. The joint between the roof and the tower base is airtight. As hot air is lighter than cold air it rises up through the chimney. Suction from the tower then draws in more hot air from the collector, and cold air flows in from the outer perimeter. The solar radiation is responsible for causing a constant up-draught in the tower. The energy created through this process is converted into mechanical energy by the rising air passing through the pressure-staged wind turbines at the base of the tower, and into electrical energy by conventional generators. ”

It sounds like a very promising new technology, I really hope the demo units get built that they discuss in this website.
