Sustainable Electricity Generation with Solar Updraft Towers

Present electricity generation using fossil fuels is damaging the environment and is not sustainable, whereas solar radiation is an inexhaustible source of energy. Harnessed at reasonable costs, it can provide prosperity and a livable environment for mankind. Solar updraft towers – sometimes also called 'solar chimneys' – promise sustainable solar electricity at low costs. Solar updraft towers are solar thermal power plants utilizing a combination of a solar air collector and a central updraft tube to generate a convective flow which drives pressure staged turbines to generate electricity.
