Briza Technologies, Inc., is a Hillsborough, NJ based corporation developing innovative products and services for the domestic and international markets. Among these are the wireless and telecommunications field, wireless payment systems, data capture and management and internet security devices. Briza is now introducing a new patent pending technology to produce energy that cheaper than fossil fuels, non-polluting, renewable, and without global warming: The Hovering Wind Turbines.
Briza is proud to introduce the Hovering Wind Turbine (HWT) technology to produce clean and renewable energy less expensive than propeller-driven turbines, and the financing for this project is being arranged by Briza's New York investment bankers, utilizing a variety of U.S. and international public/private mechanisms that are available for the financing of new and renewable sources of energy.
Currently there are three designs of wind turbines, with some innovative new designs currently being developed. The three are the propeller-driven turbines, the Darrieus turbines, and the helical generators. Each of these designs can be modified to operate in offshore wind farms, however they do require complex towers or similar constructions to hold them in place.
Darrieus Turbines - Unlike propeller turbines, are turbines that incorporate a vertical drive shaft into the blade design so that the blades can capture the wind from whichever direction the wind comes. This turbine-assembling configuration eliminates the need for the tower.
Darrieus turbines by design are placed close to ground level, which make them susceptible to natural obstacles, buildings, trees, hills, and others objects that could be in the way; blocking the wind.
Many measures have been proposed for capturing the tremendous energy available in high altitude winds, but most of them were impractical, high in cost, unreliable, and inefficient.
ÂIt would be extremely desirable to have the turbines installed in high altitude high winds, since wind electrical power generation is proportional to the speed of the wind cubed. This means that if the wind speed doubles, the power generated is multiplied by eight.Â Said doctor Macedo, the inventor of the Hovering Wind Turbine.
HWTÂs technology offers a practical, reliable, and very efficient solution to install the wind turbines without the need for towers at high altitudes, where winds are normally stronger than closer to ground level. This means the potential to produce more electricity with much smaller rotors, since turbines would be capturing the high velocity high altitude winds.
ÂThe worldÂs largest wind farm, Horns Rev offshore wind farm in Denmark, comprises 80 wind turbines each rated at 2000 kilowatt. The total weight of each turbine is 100 tons. It requires a 160-ton tower supported by a 200-ton foundation rammed up to 25 meters into the seabed. The cost of project was 270 million EUR, which represents 1687 EUR per installed kilowatt. If HWT technology were used for this project the need for these towers would be eliminated, which it would result in tremendous reductions of the cost and the complexity of this operationÂ, said Ivan Silva, President and CEO of Briza Technologies.
Wind turbines that are capable of generating 1 MW of electrical energy are now relatively common among the propeller-driven turbines. A turbine this size could provide sufficient electricity to power approximately 300 US homes, and save over 2000 tons of greenhouse gas emissions per year.
HWT eliminates the need of expensive towers; it provides the meanings to capture the tremendous energy available in high altitude winds; its modular configuration allows huge economy of scale; and it is the only economic solution for deeper offshore wind farm applications. HWT can also be used to produce hydrogen, cheaper than fossil fuels, non-polluting, and with no global warming.
