"Solar tower technology is based on some simple physics ie. Hot air must rise or be drawn towards an area of lower pressure."

This solar tower concept was developed by German designers, Schlaich Bergermann and Partner. It is being commercialized by Enviromission Ltd. of Australia and Solar technologies of the U.S.A.

The sun’s radiation (sunshine) is used to heat the air under the collector zone as the collector zone gradually slopes up from the outside perimeter of about 3meters towards the central tower at about 25 meters the air under it must follow its natural course of up and out, as the air is heated and moves continuously towards the central tower where it rises in both temperature and velocity as the hot air finally reaches the center of the tower where it is around 70 degrees Celsius and moving at about 30-35 km/hr or 15-16 meters per second the air is then drawn towards the cooler air above the tower this draft (convection) or wind energy finds its way through 32 x 6.25 mw pressure staged turbines which are housed near the bottom of the solar tower to produce electricity continually through a 24 hour 7 days a week cycle producing 200mw of green power at its highest output or enough energy for about 800,000 people.

Even at night power is still generated because as the sun heats a special heat absorbing material under the collector zone during the day and as night falls heat is reradiated from this material and thus heats the air above resulting in power generation as mentioned above.

Solar Pyramids takes full advantage of the thermal and light energy from the sun by using multi-systems to harness the power of the sun. As it uses multi-systems and makes full use of the thermal and light energy from the sun, the invention can be of a sufficient large scale for commercial production of power on a continuous basis, 24 hours a day and 7 times a week

The Power Plant is particularly reliable and not liable to break down, in comparison with other solar generating plants. Turbines, transmission and generator which subject to a steady flow of air, are the plant's only moving parts. This simple and robust structure guarantees operation that needs little maintenance and of course no combustible fuel.

The structure is a pyramid-like with 4 side frames, each side frame being angled from 30 degrees to 60 degrees as measured from the base, depending on location of the power plant and sun's maximum azimuth. The width of the base and height of the structure depends on the power generation output. The foundation of the structure consists of mild steel concrete plinths, beams and columns with steel encasing therein, forming a pyramid-like structure (hereinafter referred to as pyramid structure).

Each side frame of the pyramid structure consists of multi Layered Panels to accommodate at least four layers, starting from the uppermost layer to the lowermost layer:

• Layer 1 (a "Heating Layer"),
• Layer 2 (a "Heat Transfer Layer"),
• Layer 3 (a "Heat absorption and transfer Layer"), and
• Layer 4 (a "Heat retention Layer")
