Abstract

A solar chimney type electrical generator comprises panels A which may be dome or pyramid shaped, and solar absorbers D which may be black painted aluminum discs which may have a parabolic shape. Solar heat is transferred to air within the system which rises due to buoyancy to drive a turbine. The system may be sealed so that the air re-circulates between inner chimney B and the outer panels A. Alternatively the device may be mounted on the side of a building (figure 5) where it can also extract air from the building, especially heated air from e.g, a kitchen or laundry.

Description

Page 1 Hybrid Wind-Solar System using Concentrated Solar Energy and Thermal Chimney for Electric Generation The invention relates to an improved renewable energy generator incorporating with in one single system different Natural and Renewable Energy Effects of Solar, Greenhouse, Vortex, Chimney and Wind Turbine.
According to a first aspect of the invention is the use of Concentrated Solar Technology with modified Solar Absorber to heat trapped air with in an enclosed chamber of specific shape of chimney. Natural Air Flow of the lighter air is caused with in chamber towards the neck of the chimney. The velocity of the air is increased due to chimney effect much higher than that at the base of the chimney. * S
According to a second aspect of the invention is that the made-up *,. air flow of higher velocity is directed to rotate a modified vertical :. wind turbine. Renewable electrical energy is generated by continuously transfer of combined energy of Solar-Wind, *** Greenhouse and Chimney Effects. Inventors claim that so far no * similar combination of all of the named Energy Effects have been used with in one single system to generate power as presented herewith. Inventors' claims that their proposed invented systems can be used in any town or cities; where the present Solar-PV and Wind Turbine systems used separate units cannot be used.

(a) Both Pyramids are made of toughen glass. (b) Lower opening of outer Pyramid is sealed with insulated base from pollution and atmospheric environment. (c) The sealed chamber of required parameters is filled with atmospheric air. (d) A set of concentrated solar disc with modified absorbers are sited on base of the outer Pyramid. (e) Other inner Pyramid of the chimney shape is sited as shown with air gab between the base and opening at lower inner Pyramid / chimney. (1) Aluminium fins of Solar Absorbers are sited for maximum heat transfer to air. (g) The kinetic energy of air of the higher pressure, temperature and velocity is used to operate the vertical wind turbine. (h) Pressure, temperature and velocity of the air are reduced by loss of the kinetic energy and it is sucked into lower opening of the inner Pyramid for continuous cycle. (1) top of Outer Pyramid is open as shown to allow extra cooling and passage for wires and fittings.
