The solar updraft tower is a design concept for a renewable-energy power plant for generating electricity from low-temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like ro

The concept of a vortex engine or atmospheric vortex engine, independently proposed by Norman Louat and Louis M. Michaud, aims to replace large physical chimneys with a vortex of air created by a shor
Solar updraft tower
…updraft may be enhanced by crosswind at the upper level – creating a low pressure vortex across the top of the chimney would increase updraft. The atmospheric vortex proposal replaces the physical chimney by a controlled or 'anchored' cyclonic updraft vortex. Depending on the column gradient of temperature and…
