I don't think developers claim to exceed the Betz limit. That idea was proposed in another story. The engineer working on the equipment to do so was planning on removing heat from the passing air, enough to exceed the energy level predicted by the Betz limit. I believe it to be theoretically possible. A working prototype of such a device will be interesting proof. Paul Paul Mr. Loritz:

I don't see how you could extract more energy from the available wind, even with this 'technology'. Interesting but the Betz limit still applies.
