Earthtronics (Honeywell Windtronics) WT 6000


Earthtronics is now promoting the WT6000 Gearless Blade Tip Power System dubbed the Honeywell Wind Turbine. The company now claims that the multiblade wind turbine is 6 feet (1.83 m) in diameter. Thus, the turbine sweeps 2.6 m². The previous iteration used a rotor 5 feet (1.52 m) in diameter sweeping 1.8 m².

However, the manufacturer claims that the new turbine will still produce 1,500 kWh/year or the equivalent yield of 577 kWh/m²/year. In comparison to other small wind turbines, the Earthtronics will need to be exposed to a wind resource of 6.5-7.0 m/s (15-16 mph) annual wind speed. Consumers are unlikely to find few if any sites in Michigan and especially at rooftop heights that windy.

Conclusion? Again, it's unlikely that this wind turbine will produce the reported generation anywhere in Michigan by a large margin.
