"it can't be using the stored energy in the propeller"
Note that I didn't say it was. Sorry to get you off-script.
As claimed by the builders, the propeller is powered by the wheels. Assuming no other stored energy source, the stored energy is the motion of the vehicle after it's been started off by the wind. I'm not clear how they do it, but going from the treadmill video, I suspect they manage a temporary burst of speed followed by a slowdown.
"I don't recall attempting to force you to disprove anything"
You rushed in to try to get a layman to give explicit parameters for disproving it. That's a common tactic, usually followed by assurances that this system can totally do that, and we'll see video of it doing exactly that Real Soon Now.
At this point, I'm waiting for the normal course of events: the other shoe will drop months from now and hardly make a blip on the blogs and other venues currently hyping this story.
