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 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. A simple description of a solar chimney is that of a vertical shaft utilizing solar energy to enhance the natural stack ventilation through a building.
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.
However, power generation by the energy tower is affected by the weather: it slows down each time the ambient humidity increases (such as during a rainstorm), or the temperature falls. A related approach is the solar updraft tower, which heats air in glass enclosures at ground level and sends the heated air up a tower driving turbines at the ...
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.

In 1992, Solar Turbines introduced the SoLoNOx system. The SoLoNOx system uses lean-burn technologies to reduce NOx emissions. The SoLoNOx system has been retrofitted to over 2,000 turbines and all of Solar Turbine's more recent designs can be equipped with SoLoNOx as a feature. In 1997, Solar Turbines introduced a ceramic hot-section design ...
