Abstract

A solar thermal heating device includes a fluid which may be air 1 which may be heated using solar heating or waste heat means. The device includes at least one tube or pipe 2 which may be coloured black. Heating the fluid causes an increase in the fluid pressure. This pressure then drives means to produce mechanical power which may be a turbine 3 which causes a pressure drop. Some of this mechanical power then drives a pump or generates electricity 4 with an electrical generator 5 with some power resupplying the solar heating means with more working fluid using means which may be a pump and/or a compressor 6 which creates higher pressure in the re-supply pipe 7. There may be two or more tubes and/or pipes and the fluid cycle may be open with an air intake Fig 2, 8 and an air outlet Fig 2, 9 or the fluid cycle may be closed.

Description

Reduced cost solar generator This invention relates to generating electricity from solar power that is economically viable and competitive.
Renewable energy is important in many different ways however it needs to be as low cost as possible for it to truly be renewable. Solar power has huge potential as a generator of electricity, however the complexity and cost of solar panels holds it back from being a real]y solid renewable form of energy. To overcome this, the present invention proposes at least one tube and/or at least one pipe, said tube and/or pipe having means to be heated, said tube and/or pipe containing a fluid wherein said heating produces fluid pressure when said tube and/or pipe is heated, said fluid pressure driving means to generate mechanical power and/or electricity, wherein at least part of said mechanical power and/or electricity drives means to re-supply fresh and/or said fluid to said tube and/or pipe.
Heating the fluid can take place over a large area to concentrate fluid pressure onto the mechanical power or electricity generating means leaving most of the heating means to be low tech and low cost.
Preferably, said heat is provided by solar rays.
Preferably, said heat is provided by low grade waste heat.
Preferably, said fluid is air.
Preferably, said tube and/or pipe is coloured black.
Preferably, there are two or more tubes and/or pipes.
Preferably, said means to generate mechanical power is at least one turbine.
Preferably, said means to re-suppLy fresh and/or said fluid to said tube and/or pipe is at least one pump and/or at least one compressor.
Preferably, there are two or more turbines.
Preferably, there are two or more pumps and/or compressors.
Preferably, said fluid cycle is open.
Preferably, said fluid cycle is closed.
An example of the invention will now be described by referring to the accompanying drawing: -figure 1 shows a top view of the Reduced cost solar generator and; -figure 2 shows a top view of the Reduced cost solar generator according to the invention. n
A fluid cycle includes a fluid which may be air 1 which is contained within at least one tube and/or at least one pipe 2 which may be coloured black which is heated by means which may be solar heating or waste heat means which causes fluid pressure in the tube or pipe. This pressure then drives means to produce mechanical power which may be a turbine 3 which causes a pressure drop. Some of this mechanical power then generates electricity 4 with an electricai generator 5 with some power resupplying the solar heating means with more working fluid using means which may be a pump and/or a compressor 6 which creates higher pressure in the re-supply pipe 7. There may be two or more tubes and/or pipes and the fluid cycle may be open with an air intake B and an air outlet 9 or the fluid cycle may be closed.
At the turbine a heat sink with or without a fan can help to keep a good temperature difference to optimise efficiency, or a separate fluid supply could be utilised as a hot water supply or heating fiuid to further increase efficiency.
The cycle can utilise waste heat by having the tubes or pipes submerged in water heated with waste heat.
The tubes and pipes can also be contained under plastic or glass with black surroundings/background or covers to trap as much heat as possible.
The open cycle can be run with or without an air filter. If run as an open cycle the air exhaust can be utilised as a heating fluid for space heating if required.
Unlike photovoitaic's there is no restriction on the type of materials used as long as they have the sufficient thermal properties required, which enables them to be made of the cheapest or most environmentally friendly materials possible.
Black flexible plastic sheeting with black flexible plastic tubing laid on top covered with transparent flexible plastic sheeting, all staked to the ground, may provide one of the cheapest and quickest methods of employing the reduced cost solar generator.
A small conventional solar panel with a diode can be connected to the electrical generator, or a separate starting motor, to start the solar panel when the sun starts shining. The panel essentially becomes a self staring low temperature gas turbine with external heating.
