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.

The first free-turbine gas turbine engine was the Bristol Theseus turboprop. [8] This was the first Bristol gas turbine and its broad design had been produced by Frank Owner at Tockington Manor. It first ran in July 1945 and in December 1946 was the first turboprop to pass a 100 hour type test. [8] Some large turboprop engines, such as the ...
It is the 4th tallest building in the city at 112.5 metres to the top of solar chimney with a total of 22 stories and 690,000 square feet (64,000 square metres) floor space. The building is intended to be one of the most energy-efficient building of its size in North America, and to consume 60% less energy than the national building code ...
The stack effect or chimney effect is the movement of air into and out of buildings through unsealed openings, chimneys, flue-gas stacks, or other purposefully designed openings or containers, resulting from air buoyancy. Buoyancy occurs due to a difference in indoor-to-outdoor air density resulting from temperature and moisture differences ...
Pumps lift the water to the top of the tower and then spray the water inside the tower. Evaporation of water cools the hot, dry air hovering at the top. The cooled air, now denser than the outside warmer air, falls through the cylinder, spinning a turbine at the bottom. The turbine drives a generator which produces the electricity.
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.
