Mess with your minds: A wind powered craft going faster than a tail wind speed.

As mentioned many time before. If you are not convinced by my correct calculations you just need to test. And I promise if you (any of you) can demonstrate vehicle moving from left to right I will pay you back for the experiment.

The pole you are getting up on is getting very high, remember the distance to fall is also getting longer all the time.....

The propeller, IMO, is a red herring.

Can't say I agree with that.

I would change "possible" to "certain"

I quite agree!
--- Quote ---See my reply #20. I would have hoped that once it was understood that a vehicle driven by an overhead belt could be made to go either direction at an arbitrary speed, subbing the propeller and wind back in for the overhead wheel and belt would have made it all easier to understand. Unfortunately this does not appear to have worked all that well.

Personally, I found your variation more confusing - but that may be because you moved to a somewhat different framework. Kudos for making the effort and being creative.

Agree completely on this question - and I am struggling to come up with any suggestions to answer it.

Serious question: How do you store energy in air which is not contained in any way?
Your previous hand-waving and "intuition" has not been informative, let alone convincing.

And say breaking power is 100W say that is 10N at 10m/s

Can you cite any examples, formulas, equations, papers--any evidence at all--to support the theory that is possible to store non-negligible amounts of energy in uncontained air for any significant amount of time? Or is this a heretofore unnoted phenomenon that you are positing to exist simply because it is the only explanation that suits your 'intuition' and resultant belief that conservation of energy some how rules out all the other explanations for how the vehicle works?
