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.
The solar chimney can be improved by integrating it with a trombe wall. The added advantage of this design is that the system may be reversed during the cold season, providing solar heating instead. 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.
The solar vortex engine prototype at Universiti Teknologi PETRONAS The concept of a vortex engine or atmospheric vortex engine ( AVE ), independently proposed by Norman Louat [ 1 ] and Louis M. Michaud, [ 2 ] aims to replace large physical chimneys with a vortex of air created by a shorter, less-expensive structure.
Combination system: This can be constructed with dampers that allow either closed or open operation, depending on fresh air ventilation requirements. Such a design, even in closed loop mode, could draw a quantity of fresh air when an air pressure drop is created by a solar chimney, clothes dryer, fireplace, kitchen or bathroom exhaust vents. It ...
EnviroMission (ASX: EVM) is an Australian company founded on 2 November 2000 [1] [2] [3] as an Australian public company. [3] It has, since 2001, proposed to build a solar updraft tower power generating station known as Solar Tower Buronga in western New South Wales at a site 25 km northeast of Mildura.
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 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.
Wind projects also revitalize the economy of rural communities by providing steady income to farmers and other landowners. Each wind turbine contributes $3,000 to $5,000 or more per year in rental income, while farmers continue to grow crops or graze cattle up to the foot of the turbines." – American Wind Energy Association (2009).
