Wind Harvester™ Specifications Released

10/14/22

With the completion of testing, data collection, and analysis of our prototype Model 3.1 vertical axis wind turbine (VAWT), we were able to update and publish the specifications for our Wind Harvester™ 4.0-70. We are excited to bring the first mid-size H-type VAWT through certification with funding from our crowdfunding offering. Here are some additional explanations of its specifications:

• Model 4.0’s power performance curve and annual energy production rival many large traditional turbines. When placed in pairs to take advantage of the Coupled Vortex Effect, Wind Harvesters will produce 3000 MWh per year for each MW installed where the wind averages 7 m/s. This amount results in a 34% Capacity Factor (CF) for our Model 4.0 Wind Harvesters. The most efficient propeller-type turbine (aka HAWT) operating in a similar average annual wind speed can achieve a CF of 37%.
• Wind Harvesters come with three tower height options. In HAWTs, the “hub height” and the tower height are essentially the same. Because our towers extend up between the blades but not to the middle of the rotor, their height is not the same as “hub height”. Hub height in an H-type VAWT is found by adding half of its rotor height to the distance between the bottom of its blades to the ground.
