Arizona to develop solar tower

Arizona will build a large solar tower after receiving purchase agreement approval from the Southern California Public Power Authority (SCPPA) for power from the plant. Concept developer, EnviroMission will use a new technology to construct 1km high, 130m wide cylindrical tower capable of heating air used to power 200MW wind turbines. Water will be in a greenhouse located beneath the tower; the water temperature will rise to 70C from the heat of the sun creating a hot draft with the capacity to power 32 6.5MW wind turbines. The facility will operate for 12 hours a day at full capacity. When complete, the tower will be the tallest building in the world.
