Great success in trying to generate electricity at night with solar energy. Scientists have devised a method that can double the amount of energy from a solar power station.
A study published in the journal Energy Reports proposes a system called a solar tower power plant, which consists of a chimney-like tower with a mechanical turbine mounted at its base.
The system consists of two parts, one is the solar updraft system and the other is the cooling downdraft structure. The air inside the tower, when heated after absorbing solar radiation, creates an updraft, i.e. the air moves upwards and turns the turbine, which in turn generates electricity.
However, this early model, created by Spanish engineers in the 1980s, was not adopted because it was too expensive for its size. Conventional power plants of this design also have limited energy production as they depend on solar radiation and operate only during the day.
Now scientists from Qatar and Jordan have achieved better results by combining downdraft technology with improved updrafts.
