"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.

Me: "it can't be using the stored energy in the propeller" You: "Note that I didn't say it was. Sorry to get you off-script." Wow -- you make a clear claim and then two posts later are denying you even said it. I'll refresh your memory: This is you claiming that the vehicle uses stored energy: "It is admittedly using stored energy - the propellers are spun by the wheels," You: "You rushed in to try to get a layman to give explicit parameters for disproving it." Nope -- I merely asked what would convince you -- big difference.

  Two posts? You're contradicting yourself within your single post, right here. I never said the energy was stored in the propeller. You even just quoted me saying exactly the opposite, twice! Real, working projects don't have shills - sorry, evangelists - running around here and other forums trying to shout down people who are dubious about the very physical possibility of what they've made. They don't have to - they have working machines!

    Wow -- just wow. Moving on.
