Breaking News: Wind Harvester Blade Die and Generators Ordered

Thanks to Netcapital investors, Wind Harvest has ordered the generators and blade extrusion die to make Wind Harvester™ 4.0 turbines! 

The custom extrusion die needed to make Wind Harvester 4.0’s aircraft aluminum blades was ordered in April, 2024 and will be produced by Step-G, a premier aluminum extrusion company in Germany. Making the 160,000 pound extrusion die is the first step in the process of producing the aluminum blades. Each die produces enough blades for 83 of our turbines, and is fully recyclable.

Soga Energy in Italy is a leading developer of permanent magnet generators and motors in Europe. Working closely with our team of engineers, they have adapted a horizontal axis wind turbine’s 80kW generator to work in a vertical alignment. They were also able to customize it to improve efficiency based on data an analysis from their generator that was used on Model 3.1.  

Below is the Soga generator we used in Model 3.1. With its horizontally aligned rotation, it was originally made for a HAWT. Adapting it to our VAWT wasn’t easy.  See the story here.

The extrusion die and blade manufacturing are among the parts with the longest lead time. With this purchase, two Wind Harvesters 4.0 are  now on an installation timeline of  early autumn 2024. Stay tuned for updates.
