I am very intrigued by the concept of wind solar power. It is an extremely powerful idea which uses a lot fo existing technology to create electricity from the sun. They use a lot less heat than other designs making them safer, and they do not require complicated mirror arrays or tracking technology in order to harness the sun's energy.
The higher into the air you go, the greater the pressure difference. That is one reason why chimneys for factories and powerplants are so tall. This difference in pressure will naturally suck air out from the bottom and create an updraft.
In order to encourage the air to move more swiftly, the base of these towers are surrounded with a "plastic tent" which collects the sunlight and creates a warm-air environment. The differences in both pressure and temperature creates a powerful updraft which rushes through the tower, producing electricity from a wind turbine stored in the tower.
Plus, the ground underneath the plastic sheeting can be lined with sand or rocks to create a heat sink that can create power into the night. Other ideas include using the base of the tower as a greenhouse that can produce greens for the community.
There is talk of creating 400 MW solar towers in Namibia Africa. We can only hope that they will truly be a success.
