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 [...]
An Engineering Journey: Paving the way to turbine certification
9/30/22 Many vertical axis wind turbines have experienced catastrophic fatigue failures. Engineers couldn’t predict the harmonic excitation the machines would realize when finally built and operating. Nor could their engineers accurately predict the loads created by the aerodynamic forces on the blades through their [...]
Winds of Change: Historic Momentum Building for Renewables
9/16/22 Now more than ever before, renewable energy is entering an era of opportunity. Nationwide, we are experiencing increasing numbers of blackouts, thanks to increases in extreme weather and energy insecurity, all while fossil fuel prices and environmental costs continue to rise. Meanwhile, resources [...]
Press Release: New Breakthrough Technology For Wind Farms Begins Second Crowdfunding Campaign
New Breakthrough Technology For Wind Farms Begins Second Crowdfunding Campaign Davis, Calif.: This week, Wind Harvest, developer of an H-type, vertical axis wind turbine, has launched its 2nd Crowdfunding campaign on the successful SEC- approved platform, Wefunder. After raising nearly $1.5M in 2020-2021, Wind Harvest has opened a [...]
Project Development Advances with Reorganization
With the design and engineering of Model 4.0 essentially finished, we have been able to put more attention into the development of our projects. Our stretch goal is to order 50 Wind Harvester turbines right after we validate our modeling for a third time with data from the [...]
Technology Readiness Levels: The Path to Commercialization
Wind Harvest is proud to have the first H-type vertical axis wind turbine to achieve Technology Readiness Level (TRL) 7. Data collected from the Wind Harvester 3.1-50kW validated all key predictions from our Eole suite of VAWT aeroelastic engineering models: frequency response (where harmonic resonance will occur); loads [...]
Minor Maintenance, Major Savings with Wind Harvesters
Model 3.1 has undergone some basic maintenance; we installed the automated grease cartridges for the bearings in the drive shaft and the generator. The process of maintaining Wind Harvesters is fast and simple, especially compared to the costly and time-consuming processes needed for maintenance on traditional turbines. See [...]
Model 3.1 Overcomes its Final Challenges and Begins 24-hr Operations
Model 3.1 is officially running 24/7! The unexpected blackout last week interrupted the beginning of testing 24-hour autonomous operations. The final challenge in beginning official 24-hour operations was the successful verification of engineer Mark Chang’s Variable Speed Algorithm (VSA), which truncates energy output as wind speeds reach rated [...]
Surprise Blackout Provides Learning Opportunity
Tuesday evening, our engineers received an alert that our Model 3.1 had shut down during a period of autonomous operations. Mark Chang, Jeff Willis, and Antonio Ojeda responded to a report of power loss at the UL testing facilities in Texas caused by an automobile accident that knocked [...]
