Abstract
Abstract A solar energy powered hot air turbine comprising a heat collector having an air inlet and outlet with the turbine connected to the air inlet. The heat collector is heated by solar energy and is constructed so that the hot air exhausts through the air outlet thus sucking air in through the air inlet to power the turbine.
