Wind technology is an alternative to the traditional means of generating electricity through the burning of fossil fuels and the spewing of carbon dioxide into the atmosphere. After 15 years of extensive researching and testing, our new technical breakthroughs allow us to roll out a new series of products in The 2009 Chicago Wind Conference.
Our innovative design builds upon work by Mr. Wang and his team with improvements to address Windmill energy output efficiency, vibration, durability and manufacturability (i.e. cost). For residential uses the emphasis is on silence, footprint, safety and aesthetics.
Advantages of Vertical Axis Wind Turbine (VAWT):
- VAWTs are omni-directional, so they do not suffer from the 20.56% "gyroscopic" penalty on Horizontal Axis Wind Turbine's (HAWT).
- VAWTs have better power output at lower wind speeds. Wind speeds follow a Rayleigh distribution in which milder winds predominate.
- Fiberglass blades are stiff, fatigue-free, and strong in high winds. Unlike HAWTs, they are supported at both ends and the self-supporting VAWT blade design reduces parasitic losses by eliminating all struts.
- VAWTs are ideally suited to direct-drive generators, which circumvent the reliability problems of speed reducers at high power.
- Catastrophic high-wind failure can be prevented by a relatively inexpensive fail safe shaft caliper brake.
- Location of the generator is at ground level! The VAWT design allows for single or a multi generator configuration at a more convienent ground level location. This also reduces the cost (and risk) of maintenance as compared to Horizontal Axis Wind Turbines.
Environment - Noise & Emissions:
Our design includes fewer moving parts that increase performance while decreasing noise levels. Without consuming any natural resources or emitting any greenhouse gases.
- One Mega Watt of power generated from a wind turbine displaces 1,800 tons of carbon dioxide each year (equivalent to planting a square mile of forest), based on the current average U.S. utility fuel mix. To generate the same amount of electricity as a single One Mega Watt turbine using the average U.S. utility fuel mix requires the emission of 9 tons of sulfur dioxide and 4 tons of nitrogen oxide each year.
- To generate the same amount of electricity as a single One Mega Watt wind turbine for 20 years would require burning 29,000 tons of coal (a line of 10-ton trucks 11 miles long) or 92,000 barrels of oil.
- To generate the same amount of electricity as today's U.S. wind turbine fleet (6,740 MW) would require burning 9 million tons of coal (a line of 10-ton trucks 3,437 miles long) or 28 million barrels of oil each year.
Note: 100,000 Mega Watts of wind energy will reduce CO2 production by nearly 150 million tons annually!
Safety:
Because our wind turbines will be located close to urban areas, reliability and safety is imperative. Our wind turbines were originally designed to withstand the harsh environments of the Arctic, where access for repairs and maintenance are limited to weeks a year. The failure proof design of our wind turbines and components is paramount. This quality and structural integrity requirement for the North integrated well into safety for urban sites. Our wind turbines will incorporate two braking systems- Automatic and Manual Brakes.
The eight safety advantages of our Vertical Axis Wind Turbine over horizontal turbines include:
-Fiberglass blades securely attached to a triangle frame at both ends
-Internal safety cable
-Remote monitoring
-Disc braking system
-Motor Brake
-Load resistor brake
-Vibration sensors
-Integrated Smart Controller
Advantages our design over other VAWTs
-Magnet Direct Drive Generators. Our new design eliminates the requirement for the separate inverter, reducing cost tremendously.
-Use of newest Ceramic Bearings reduces maintenance or our VAWT.
