Donation Portal

Our goal is to help reduce the climate crisis by getting this innovative and efficient wind generator out into the fields where it can help generate electricity close to where it is needed for residential, commercial, and agricultural customers.

We have made our licenses affordable so that many manufacturers can make and market them to green-minded consumers.  Three years of computer-aided design and testing have shown it has great potential, and we are excited to take the next step; building a working prototype and submitting it for certification to the Small Wind Certification Council (SWCC).

SWCC StampYour dollars, in any amount, will help. The SWCC’s certification will go a long way to help interested parties buy their airfoil generator with the confidence it actually will do what we say it does.

Please help us push this promising tech forward. Development and certification is expensive and we need your contribution.

Your donation is completely safe. It will travel through a secure portal at, the leader in advancing Renewable Energy and Green Tech through crowdfunding.
