Wind turbines don’t necessarily have to be in huge windfarms any more. WindTronics, a division of Honeywell, is selling the The Blade Tip Power System™ which addresses past constraints such as size, noise, vibration and output, utilizing a ring around the blades that shrouds the system and is more distinguishable to wildlife. The system is small and quiet, so that it can be installed in homes and businesses.
The generator utilizes a system of magnets and stators surrounding its outer ring to capture power at the blade tips where speed is greatest, practically eliminating mechanical resistance and drag.
Specifications as per the company’s website:
Our wind turbine is a gearless wind turbine that measures just 6 feet (1.8 m) in diameter, weighs 241 lbs (110 kgs) and produces up to 1500 kWh’s per year depending on height and location. Our Wind Turbine’s BTPS perimeter power system and unique design of multi-stage blades allows the system to react quickly to changes in wind speed. This ensures that the maximum wind energy is captured without the typical noise and vibration associated with traditional wind turbines. Our wind turbine has an increased operating span over traditional turbines with a start-up speed as low as 0.5 mph (0.2 m/s), cut in at 3 mph (1.34 m/s), with an auto shut off at 38 mph (17.0 m/s), traditional gearbox turbines require minimum wind speeds of 7.5 mph (3.5 m/s) to cut in and start generating power. Our wind turbine is designed to be installed by a licensed electrician wherever energy is consumed, turning homes and businesses from points of total consumption to distributed energy sources, in a cost effective and efficient manner.
