Press Release: UK rare-earth-free innovator GreenSpur receives generator order from US firm Wind Harvest
UK rare-earth-free innovator GreenSpur receives generator order from US firm Wind Harvest The delivery of three patented 70kW rare-earth-free generators in mid-2022 will support Wind Harvest’s vertical axis wind turbine design ambitions. Davis, CA | UK firm GreenSpur Wind has confirmed an order for three 70kW rare-earth-free permanent [...]
CEO Visits Prototype Turbine at UL Testing Facility
CEO Visits Prototype Turbine at UL Testing Facility Model 3.1 Undergoing pre-operational testing at the Wind Energy UL Testing Facility in Texas After extensive work by the project manager, Jeff Willis, and electrical engineer Mark Chang, our prototype turbine in Texas began its pre-operational testing this week. [...]
Final steps before start up
Bringing a prototype turbine through the last tasks before operation involves a process of sequential steps, each one critically dependent on the completion of the previous. Commercial turbines, like our Model 4.0, benefit greatly from the deliberate and meticulous processes its predecessors go through. The process is as follows: [...]
Press Release: Untapped Power of Mid-Level Wind Positions Wind Harvest and Investors for Unprecedented Success
Untapped Power of Mid-level Wind Positions Wind Harvest and Investors for Unprecedented Success DAVIS, CA -- Wind Harvest International, Inc. (WH), a company that designs, sells, and develops projects unique, mid-size wind turbines that capture and convert the unused and highly energetic mid-level wind layers into electrical power, [...]
Brake, and Coupler Steps Completed
The delay caused by the unexpected requirement of a letter of credit created a backlog of work that descended on the test site on Thursday and Friday. We bolted the brake disk onto the bottom of the Soga generator and attached the caliper brakes. The generator is now connected [...]
Bureaucratic Problem Solved. Installation Restarts
On October 1 we were notified by West Texas A&M University, the owner of the property on which the UL Advanced Wind Turbine Testing Facility is installed, that we needed a letter of credit proving that funds were set aside to ensure the turbines would be removed after our [...]
Turbine Controls Build from Model 2.0’s Success
Electrical engineer extraordinaire Mark Chang is heading down to Texas on October 22 to conduct the turbine’s final check-off and begin its testing. He brings with him the knowledge he gained when developing, installing, and operating the controls for our Wind Harvester Model 2.0 that passed through Technology Readiness [...]
Frequency Response Static Test is a Success
Not knowing where the RPM of the rotor overlaps with the harmonic resonance of H-type turbines has been one of the biggest hurdles that have prevented them from being commercialized. Dr. David Malcolm’s extensive knowledge and modeling of our turbines’ frequency response was tested today when Jeff Willis conducted [...]
Control Panels Arrive from Pennsylvania
Dan Clunies with Windurance drove our Model 3.1 control panels from PA to TX to make sure they arrived safely. The resistor brake, which helps control the turbine speed and produces heat when engaged, is in the first enclosure with the slotted vent holes. The vents serve to dissipate [...]
Generator Installed
It took ingenuity and solid engineering skills to adapt the replacement Soga permanent magnet generator (PMG) to our existing turbine tower and drive train. With Jeff Willis’s leadership and Antonio Ojeda’s engineering genius, the generator is installed on its platform and ready to go. The top photo shows the [...]
