The Power-Spar® is a revolutionary high efficiency solar concentrator that can be configured for electricity, heat, cooling and/or lighting solutions. The Power-Spar® system consists of a parabolic trough reflector which concentrates the sun's energy onto a modular absorber. The absorber converts the sun's energy to electricity (via high efficiency multi-sun photovoltaic cells), or to heat (via a patented absorption surface) or transports the light to the buildings' interior (via optical cabling).

The system is designed for easy integration with heat recovery systems, turbines, thermal based chillers and geo-thermal solutions to maximize the thermal, electrical and lighting outputs. This efficient co-generation yields unprecedented dollar value.

Capable of capturing up to 80% of the sun's energy, Power- Spar systems can reduce typical building energy bills by as much as 70%/year!

" IAUS's new solar technology is the first to offer the possibility of competing head-to-head with fossil fuels for both electricity and gasoline production. It costs less now than the World Government's goal for solar power cost per kilowatt by the year 2020. IAUS's unique thin-film lens focuses the sun's energy, producing super-heated steam for power generation. IAUS's panels are inexpensive, efficient, and require virtually no maintenance. Typical solar reflector panels ( e.g. solar dishes, troughs, heliostats) are very expensive and require a great deal of maintenance to sustain a solar focal point. Once installed, IAUS's lenses need no further adjustment. Other solar technologies, such as photovoltaic (PV) panels, are also very expensive and require an expensive inverter to convert DC power to AC. They also require expensive batteries for power storage. Unlike PV systems, IAUS's product does not need an expensive inverter or battery storage. It operates on heat and produces heat as a byproduct. This energy can be stored using a chemical regeneration process held in a continuous cycle. This chemical, in turn, is then used to create steam when there is no sun. This unique added process costs significantly less than batteries; so much so, that it offers a reasonable answer to 24/7 solar power. "

" Solar Systems is a world leader in electricity production from solar concentrator methods.

Conventional photovoltaic products use unconcentrated sunlight, or "1-sun" strength. This energy is quite diffuse so large panels of photovoltaic (PV) material must be used. This requires large amounts of silicon and expensive photovoltaic materials. As well, the panels are usually mounted in a fixed position as the cost of tracking the sun for optimum output is difficult to justify.

Solar Systems reasoned that while PV is expensive, steel and glass are relatively cheap. Therefore, if the diffuse sunlight were concentrated onto a small area of high efficiency PV then the overall cost per unit of electricity would be lower than unconcentrated methods. With this premise, Solar Systems designed and refined the concept into the CS500 dish concentrator PV unit. " ... more

"Solar Twin Ltd was formed in 1998 following two years of research and development in solar energy. It installs solar water heating systems throughout UK and Ireland, and exports kits worldwide. We number sixteen employees working directly in the business plus numerous component suppliers, installation subcontractors and resellers.

A unique British revolution in solar water heating technology, Solartwin is a reliable, quickly fitted and affordable solar water heating system. It is based on a Scottish engineer's sudden insight on how to avoid the problem of frozen pipes bursting in winter - by just letting them freeze - flexibly! Invented and patented by Kerr MacGregor at Napier University, Edinburgh, and developed in conjunction with Solar Twin Ltd, his innovation exploits recent advances in materials science. Kerr identified highly flexible, thermally conductive pipes to accommodate the problem that water expands when it freezes. This 'freeze-tolerance' eliminates, at a stroke, any need for inefficient heat exchangers and antifreezes, and the numerous costly and power-draining control peripherals normally associated with conventional solar water heating.

Solartwin's unique pumping system uses low speed single pass water flows through the panel, rather than less efficient fast multiple passes. In addition, all of the parasitic mains electricity consumption normally associated with pumps, 24 hour solar controller circuitry and various other peripherals is completely eliminated by using a dedicated low power, variable speed, solar powered pump. Based on new high torque, rare-earth magnet technology... more "

"Open Energy Corporation is the exclusive worldwide licensee of an exciting new solar thermal technology that provides tremendous potential to end-customer benefit(s). SunCone™ CSP (Concentrating Solar Power) is the creation of Dr. Melvin Prueitt, renowned physicist and research scientist from the Los Alamos National Laboratory. SunCone™ CSP utilizes non-imaging optical cones made of reflective composites to concentrate sunlight on rods at the base of each cone. The cones stay cool, but the fluid flowing through the base is superheated, generating steam to drive a turbine and produce electricity. This same superheated fluid can be combined with reverse osmosis membranes or flash distillation equipment to produce fresh water from salt or brackish sources
Open Energy Corporation believes that SUNCONE™ CSP has the potential to be less expensive to build, operate, and maintain than competitive parabolic trough or dish power systems. The company has enlisted Hytec Engineering, an award-winning firm based in Los Alamos, New Mexico, to build the first full-scale, operational SUNCONE™ prototype... more "

"The EIS technologies have already been successful in winning two DTI Smart awards and two European Craft grants, with other grants bringing the total to nearly £2 million.
The latest of these was to support development of the solar thermal panel & VSI to run Solar Thermal Powered Air Conditioning without the need for an electricity supply.
Further work will enable the Group to develop a Combined Heat & Power System to make a property independent of external services for all heat, cooling and power; the final system could also be made to produce hydrogen for powering vehicles with the possibility of pure drinking water should it be required.
Thin Membrane Heat Pipes:
Specially made using very thin materials that enable large flat, multiple parallel heat pipes to be made. This enables very efficient heat transfers to be made up to 8kW/m² and potentially 800kW/m3.
Selective Coating:
A special coating has been developed which will be used to coat the Thin Membrane Heat Pipes. This coating has now been made available on thin nickel foil achieving a high Absorptivity of between 95 and 99% and Emissivity of 4 to 10%, with typical values of 96% and 7% respectively... more "
