The solar updraft tower (SUT) 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 roofed collector structure surrounding the central base of a very tall chimney tower.
A variation of the solar chimney concept is the solar attic. In a hot sunny climate the attic space is often blazingly hot in the summer. In a conventional building this presents a problem as it leads to the need for increased air conditioning. By integrating the attic space with a solar chimney, the hot air in the attic can be put to work.
A solar chimney (or thermal chimney) is a passive solar ventilation system composed of a hollow thermal mass connecting the interior and exterior of a building. As the chimney warms, the air inside is heated causing an updraft that pulls air through the building. These systems have been in use since Roman times and remain common in the Middle East.

Solar chimney – solar chimney — often referred to as a thermal chimney — is a way of improving the natural ventilation of buildings by using convection of air heated by passive solar energy. Solar collector – Solar cooker – or solar oven, is a device which uses the energy of sunlight to heat food or drink to cook it or sterilize it.
Heating of the windtower itself can heat the air inside (making it a solar chimney), so that it rises and pulls air out of the top of the house, creating a draft. This effect can be enhanced with a heat source at the bottom of the windtower ( such as humans, ~80 Watts each [ citation needed ] ), but this heats the house and makes it less ...
Solar Turbines Incorporated continued to introduce new versions of their axial-flow industrial engines throughout the 1980s and 90s, often re-using older names instead of introducing new names. In 1997, Solar Turbines Incorporated announced the Titan 130, a 19,500 horsepower (14,500 kW) design much larger than the original Titan.
Solar energy is clean and renewable. Solar architecture is designing buildings to use the sun's heat and light to maximum advantage and minimum disadvantage, and especially refers to harnessing solar power. It is related to the fields of optics, thermics, electronics and materials science. Both active and passive strategies are involved.
