Solar towers might make a comeback amidst the decline of fuel reserves.

Solar towers might make a comeback amidst the decline of fuel reserves.

A giant tower was built in Spain thirty years ago to produce electricity in the Manzanares region. The tower was supposed to make use of air movements to generate power, but unfortunately, the tower was toppled by a storm. After that incident, many companies tried to revive the idea by replicating it, but none of the ventures succeeded.  The idea behind the tower’s working is straightforward and simple. On the ground around the tower, a solar energy collector must be placed with a suspended transparent surface to heat the air under it. The heat produced will rise through the solar chimney and enter the tower; in this process, the wind turbines will be activated, producing energy.

This idea was popular because the air underlying in the collector will remain hot even when there is no sunshine. The most recent version of this tower was the Solar Wind Downdraft, but eventually, the idea was scarped due to insufficient funding. One of the primary reasons for projects like these lose traction is because of the cost involved. Even though the costs are high, the electricity generated from this tower is cheaper when compared to other solar techs. There is speculation that when the fuel reserves experience a decline, the demand for the solar tower will increase.
