Published in July 2002 by the Energy Research Foundation of the Netherlands, this 50-page report describes current and future Solar Thermal Power technologies. It offers a unique perspective by looking ahead to the "global energy supply and demand until 2100." Five main technologies are described, and two are examined in depth. The first is a solar tower design that uses a large array of mirrors to reflect all sunlight to a receiver at the top of a tower, and then generates electricity from a steam-powered turbine. SNAP technology is the second focus; this kind of power plant directs artificially created wind down a large tube, turning turbines as the wind escapes. A short history of each of these methods is included, as well as an analysis of world solar power potential.
