We’ve turned traditional wind turbines, inside out. The Honeywell Wind Turbine eliminates traditional wind turbine gear box, shaft and generators. The Honeywell Wind Turbine is a gearless, “free wheeling’’ turbine that generates power from the blade tips (where the speed lies) rather than through a complex slow center shaft. By practically eliminating mechanical resistance and drag, the Honeywell Wind Turbine creates significant power (2000 kWh/yr) operating in a greater range of wind speeds (2-45 mph) than traditional wind turbines. The highest output, lowest cost per kWh installed turbine ever made. So powerful, so simple.
THE HOME ENERGY SOLUTION – ALWAYS TURNING, ALWAYS GENERATING POWER
Why was it necessary to redesign the turbine? With 90% of North America’s actual wind resources (class 4) below 9 mph on average, it was essential to develop a technology capable of starting up in wind speeds as low as 2 mph and remaining operational through 45 mph. (Traditional turbines do not begin turning before 7.5 mph and shut down by 29mph to protect their gearing systems.) It is this greater capture and conversion of available wind energy that enables the Honeywell Wind Turbine to provide such a meaningful percentage of a home’s energy needs.
The Honeywell Wind Turbine’s Power Blade System creates energy at the blade tips, rather than the complicated central gear of a traditional turbine. By removing the resistance of the mechanical gear, the Honeywell Wind Turbine is far more efficient, less expensive to own and operate and creates energy across a much broader range of wind speeds.
SAVING ENERGY IS A BREEZE WITH A HONEYWELL WIND TURBINE
The turbine’s installed cost is approximately 1/3 of the cost of traditional turbines with a lower installed cost per kWh than any turbine on the market. Adding to the value are federal and state rebates covering anywhere from 30% to 100% of the overall cost.
The Honeywell Wind Turbine comes complete with a computerized smart box, inverter and interconnect switch to wire the system into a household panel. The Honeywell Wind Turbine is designed to be installed where the power is being consumed and can produce 2000 kWh/yr. The system has an MSRP of $4,500.
Generate energy at the source, for the lowest cost per kWh in the alternative energy industry. Efficiency meets innovation with the Honeywell Wind Turbine.
The high starting wind speed is a problem for many wind turbines, and the need for protection in high wind speeds is another. The blades on this concept are shrouded, which reduces the 3-D losses. The 3-D losses are the reason most designs have long thin blades. The long thin blades are more of a structural problem.
A turbine like this would work well in the solar windmill:
The solar windmill avoids the need for the turbine to turn to face the wind. The structure, with one-way flapper valves, directs wind from any direction up through the turbine. Also, the solar windmill may provide higher wind speed at the turbine, reducing the size of turbine needed for a given output.
I'm not sure and I have not seen the small graphics you refer to but I do recall they mentioned that the tips contained magnets which pass by (?) creating a current. As you can see I'm not a scientist. I'd look it up but I'll bet you will have just as good a chance of finding it yourself.
My guess is Honeywell does not mean that torque is produced only at the tips, but mostly at the tips. Notice that the blades are twice as wide at the tips as near the shaft, unlike traditional turbines which have small area near the tips. Likely the electricity is produced in a normal generator connected to the shaft. My guess is magnets at the blade tips would give poor results.
That it starts making power at 2 miles per hour wind speed, may be unimportant as turbines make 16? times more power when you double the wind speed. Eliminating the gear box is a big plus for small and mid size turbines, but likely impractical above about 10 kilowatts per turbine.
2000 kilowatt-hours per year is worth about $200 per year so pay back is 22 years or more. Neil
