Wind Energy Voice

This video is taken when windmax wind generator is on the 5.9 feet test pole and the wind is 10 mph according to weather channel. the blades performs extremely well and spinning very fast at low noise. imagine much greater performance if this wind generator is at 26 feet high !! The blade diameter is 1.4 meter or 4.9 feet. While at the same wind speed, the old style wind turbine with mechanical furling with 8.2 feet diameter blades doesn’t perform, the blades barely moved. Instead, the wind generator head is turning around, which is very bad. the blades for these old style wind turbines have poor design and such low efficiency, it can’t capture the power in the wind even with the larger swept area, that is the myth about these blades with larger swept area, most people would think that the blades with larger swept area always performs better than blades with smaller swept area, that is totally untrue, if the blades with larger swept area won’t operate/spin efficiently as shorter blades, it can’t capture the power in the wind, and it won’t output energy !!

The energy output is the energy converted by the turbine blades into mechanical energy, the turbine blades need to spin in order to convert all the wind’s power to mechanical power. The low effciency turbine blades don’t spin or barely move, there is no energy output !!!

Rated energy output of the old style wind turbines with mechnical furling and low efficiency blades is very deceiving because the blades have such low efficiency that the larger swept area output little energy, some of the old style wind turbines with mechnical furling and low efficiency claim 1000w, 2000w or more, the actual output is much lower.
