Solar Chimney Power Plant

absorber) and transmission (due to the contact with colder materials like steel wich
supports the glass roof). But just in the closer area of the roof to the chimney is to
adjust thermal covering and translucer for the air temperature which is high at the
biggest diameter and decreases with decreasing diameter. The costs for a panelling
at the sides and the support places with material that thermal covers or a vaccum
insulation of the complete absorber (glass or foil) would not been useful with a view
to the efficiency.
Than there is natural ground as an accumulator for warmth. Over the day the
ground gets heated and over the night it gives its warmth to the ascending collector
air. This effect can be supported with black tubes placed on the ground under the
glass roof. The tubes are filled with water only once (no further water is needed) to
increase the effect. Black coloured bodies have best abilities to absorb radiations of
long wave length at day to heat the water and at night to heat the air.
All in all the warm air collector. A collector which is robust , not difficult to
realise and to operate 24 hours a day. Its glass roof ascends to the middle (in two to
six metres over the ground and with up to 10m x 10m big glass segments) , so that
the heated air can accelerate on the way up to the middle where the chimney is.
