Indeed, the tower will have a diameter of 130 meters and a height of 800 meters – 60 meters higher than the Burj Dubai Khalifa!
This structure is intended to develop an installed power capacity of 200 MW, in the end enough electricity to power 100 000 to 150 000 U.S. households. But in return, the project would also require an equally enormous budget of about $ 750 million.
The Arizona desert continuously receives abundant solar radiation keeping the temperature of air at 40 ° C. The idea is to create a greenhouse at the base of the tower, so that the temperature at ground level can be increased from 80 to 90 degrees. The hot air created rushes into the tower and is heading upwards. Turbines built into the benefit system then that hot air supply to operate and generate electricity.
The impressive height of the tower is the fact that the difference in air temperature is especially important that the chimney is high, resulting in a significant gain in energy production.
The major advantage of the device is certainly a generation of energy continuously for 80 years, almost without need of maintenance.
In addition, the Southern California Public Power Authority has agreed to buy electricity produced by the turn of EnviroMission over the next 30 years.
