The first large-sized solar tower will be developed in Arizona, US, following the Southern California Public Power Authority (SCPPA) approval of the purchase agreement for power from the plant.

The next-generation plant, proposed by Australian company EnviroMission, will employ a new technology to build a 1km-high, 130m-wide cylindrical tower, heating air which will be used to power 200MW wind turbines.

The mechanism is based on a simple concept, wherein the temperature of the water in a greenhouse, located beneath the tower, will be raised by the sun's heat to reach more than 70°C, forming hot draft that can power 32 6.5MW wind turbines.

The facility would be able to operate at full capacity for 12 hours/day, according to REVE.

The tower will be three times as high as the Eiffel Tower and will be the tallest building in the world.
