List of Selsam Windpower Patents
We may have missed some. Please tell. Thanks.

We are sorting duplicate filings. A patent may be published in more than one nation or under WIPO.

An AWE study in open forum over Selsam windpower patent: AirborneWindEnergy/conversations/messages/12132

We also have a new working page in an effort to become comprehensive:  Selsam/PatentsBySelsam.html

And:  Selsam/index.html

    We asked Doug Selsam if we missed any patent. We do not have his answer yet.

This clip seems to have a core claim:

Yet in prior art inventors already realized lengthening driveshafts and adding several extra rotors.

Single moving part:

But Fry and Hise realized that a driveshaft could be the single moving part. They taught past that also and faced the challenges of high altitude which would have some rotors experience significant different winds and so taught clutching and disengaging.   Since they realized single-moving part (driveshaft with mounted rotors) then such could not be an inventive step by Selsam later; Selsam seems not to face long driveshaft going through varied wind layers with the impact of varied wind speeds.

Selsam seems to be rehearsing the arts of train kites:
Selsam seems to be rehearsing known LTA kytoons:
Selsam seems to be including known lifter-kite tactics:
