Inventor Seeks Licensee for Gulf Stream Turbine Patents


Gulf Stream Turbines LLC is seeking a suitable company or group of investors that will license an invention that can produce continuous low-cost electricity from the constantly flowing Gulf Stream.

Unlike the intermittent energy that is in the winds, tides, and waves, the Gulf Stream's kinetic energy is relatively steady because it is produced by a Coriolis force that results from the earth's eastward rotation. It is because of the Gulf Stream's greater steadiness that the Gulf Stream Turbines can continuously generate power at near their theoretical capacities, making it possible for them to produce from two to six times the electricity that can be produced by the wind turbines and at one-half to one-sixth the cost.

"Because these submersible power plants will be in the ocean, they must be able to operate for long periods without requiring servicing," said John Robson, the inventor. "This is made possible by relying on the unchanging laws of physics – rather than on mechanical systems that can fail."

Robson said, "A free-floating submerged object will always float with its center of gravity directly under its center of buoyancy. This fact not only can provide great inherent stability but also permit a machine's depth to be easily changed by transferring ballast water between the front and rear compartments of the buoyancy tank to adjust the hydrofoils' lifting forces. It also can make the machines much easier to install and recover."

Companies that generate electricity from renewable energy are eligible for a government production tax credit of 2.1 cents per kilowatt-hour for the first ten years of a renewable-energy facilities' operation. The Gulf Stream's more consistent kinetic energy not only will produce from two to six times the revenues from the sale of the electricity, but also from that subsidy.

The Gulf Stream Turbines will also produce proportionally larger reductions in the emissions of greenhouse gases. A single Gulf Stream Turbine that is equipped with two 600-kW generators will theoretically generate 8,941,300 kilowatt-hours per year, operating at 85% of its theoretical capacity. If that electricity were to replace the electricity produced by a coal plant, the CO2 emissions would be reduced by about 13,000 tons. If that electricity were to replace the electricity produced by burning natural gas, the emissions would be reduced by 5,900 tons and gas consumption by 52.85 billion Btu.

Because the earnings produced by the Gulf Stream Turbines will substantially exceed those of the other renewable energy generating systems, thousands of these machines could soon be generating electricity from that current is just off the coast of South Florida.

Gulf Stream Turbines LLC was formed in 2009 for the purpose of getting the invention into production.

The Dyson Airblade(TM) Hand Dryer Receives Industry First Carbon Reduction Label

As an industry first, Dyson's patented Airblade™ hand dryer is the first hand dryer to earn the Carbon Reduction Label from the Carbon Trust. Furthermore, Dyson research found that the manufacture of the new polycarbonate-ABS Dyson Airblade™ produces 50% less CO2 emissions than the aluminum equivalent launched in 2007.

The Carbon Reduction Label recognizes manufacturers' commitment to the further reduction of their product's carbon footprint - the amount of carbon emissions (CO2 and other greenhouse gases) produced from its materials and manufacture, transport, in-use and end of life. The Label, established in 2007 is based on PAS2050, the first internationally-accepted product carbon footprint standard. The Carbon Trust only grants their Label to companies with a 'reduce it or lose it' clause whereby if they fail to reduce the carbon footprint of the product in two years the Carbon Trust will withdraw the certification.

The rigorous process revealed that the Dyson Airblade™ hand dryer emits 1,300 kg/ CO2e total emissions during its lifetime or 3.4 g/CO2e per dry(1) – equal to the carbon emissions created by watching just over 2 minutes of television(2).

"Good design and environmental responsibility go hand in hand," says James Dyson, Chief Engineer. "As an engineering company, we are constantly reviewing our machines and manufacturing to deliver better performance using less energy and materials."

The Dyson Airblade™ hand dryer eliminates the power hungry heating element, drying hands faster, more hygienically while using nearly 80% less energy than traditional warm air dryers(3).

According to Tom Delay, Chief Executive of the Carbon Trust, "More so than ever, everything we make and do today has a carbon impact. We commend Dyson for their commitment to measure and reduce the carbon footprint of the Airblade™ hand dryer and hope our recognition helps people find opportunities to tackle climate change."
