Solar thermal technology has come of age as the world seeks solutions to the global climate crisis by reducing its use of fossil fuels and introducing sustainable alternatives sources of energy.
Solar thermal applications have been around since Man first learned that the sun’s benefits could be managed, whether through agriculture or preserving food.
Now, Free Energy is harnessing modern technology to capture the sun’s energy for hot water heating and ‘pipe’ it right to where it’s needed, at cost savings of up to 50% compared to competitors.
Competitor’s evacuated solar thermal tubes have been an excellent way to do this, but conventional designs have had limitations on the heat transfer ability of the materials used.
Now, Free Energy is harnessing superconductive material encased in metal pipes capable of moving heat at a rate 30,000 times faster than the conductivity of silver.
This ability of superconducting material to work at extreme temperature ranges of minus 60 Centigrade to 1,100 degrees Centigrade, means wide potential applications.
In the case of solar thermal, these unique characteristics have allowed Free Energy to design solar panels that work in sunny but cold conditions that typically make conventional hot water systems perform poorly.
How it works in detail
As the sun’s energy enters the Free Energy Solar Collector, it penetrates the glass tube collectors with their special absorption coating directly to heat fins connected to the superconductor tubes. At this point, the heat energy is then transferred through the superconducting tubes to the manifold located in the well-insulated header box where the water, or water/glycol mix flows to absorb the heat energy being furnished by the superconducting tubes.
Our 16 tube model, for example, can be thought of as being 16 separate energy sources constantly supplying energy to the header pipe. The heated glycol, or water, is then circulated through a heat exchanger in a storage tank, which transfers the heat energy into the stored water for multiple household uses.
WASTE TO ENERGY
Converting waste products to electricity(known as “the waste to energy cycle”) without hurting the environment through carbon dioxide emissions, has been high on the wish list of state, provincial and municipal governments, especially ones that have a shortage of space available for land fill sites.
Conventional methods have involved compaction, incineration, recycling a portion of the waste, and even decomposition of organic waste, but these methods have barely made a dent on the waste stream.
Now, Free Energy’s technology can assist in the direct conversion of municipal waste into useful electricity. Free Energy’s thermal superconducting material will act as a highly efficient heat transfer “bridge” between a 2 chamber system where solid waste is gasified and the power producing turbines at the output end of the plant.
The2 chamber gasification system meets the strictest North American standards for emissions and has been designed by EnEco Industries Ltd., (“EnEco”) a British Columbian corporation that has pioneered the “waste to energy” cycle since 1991.
This process also has the ability to handle sludge from sewage treatment plants , thus further helping reduce municipal waste streams.
Free Energy’s solution in this market space includes the benefits of:
- processing sewage treatment by products
- reducing or eliminating land fill sites with their many problems
- creating power for the grid
- and providing excess heat for use by nearby industry
This solution is “scalable” for communities from 20,000 in population and on up.
Free Energy is currently working towards finalizing a contract with EnEco for the previously announced Prescott, Arizona, municipal waste to power project that can potentially handle 200 tons of waste a day and produce 6 MW of electricity.
SEAWATER HEAT EXCHANGER
Free Energy has developed its core expertise in heating and cooling technologies with a number of products now commercially available for this huge industry. Our current focus is on completion of our Seawater Heat exchanger for a large commercial air conditioning system at a Vancouver, BC, grain terminal that experiences a high degree of contamination from dust particles. Free Energy uses its super conducting technology to create an exchanger where excess heat will be absorbed by the adjacent seawater at the rate of 360,000 BTUs an hour, allowing trouble-free operation of the air conditioning equipment and removing the need to pump seawater into the system which has been the traditional solution for this type of AC system.
The system integrates with, or replaces, existing commercial HVAC equipment in any large building, or facility located near a body of water, including fresh or brackish water.
The heat exchanger uses the Free Energy super conducting technology to transfer heat from the HVAC system used to cool the critical areas in the mechanical plant directly into the water without pumps.
This avoids having to use dust-laden air in the HVAC equipment and the issues normally associated corrosive sea water.
World demand for HVAC equipment is projected to rise over five percent per year through 2010, exceeding $65 billion. Demand in the Asia/Pacific region will outpace the global average, rising nearly seven percent annually through 2010, according to research from Freedonia Group.
