Even this took more time that will have been need to answer my question.

As long as vehicle body is constrained to ground in any way it is nothing else than a treadmill powered fan. The charged energy can not be used so it is charged and remains charged.

Ahh you're oh so, so, so close to getting it. The charged energy is NEVER used even when the vehicle is completely unrestrained - in which case the vehicle would just drive along forever beyond the wind speed, if we had a powered treadmill of infinite length. The people who invented the Blackbird told you about this and explained why in the other forum... until they lost patience with you and told you to f*ck off so now you're here to try deceiving a fresh audience of unsuspecting engineers.

Of course you'd say this - because it utterly destroys your prediction that the vehicle should speed up/slow down/speed up/slow down.

For some inexplicable reason your made-up theory of stick-slip hysteresis and "energy storage" doesn't apply to the experiment that obliterates everything you've claimed but, instead, you are relying on thought experiments with flawed premises which, essentially, become untestable hypotheses. That makes your whole approach unscientific.

No one has a linear treadmill of infinite length - and you haven't bothered to actually prove your claim that the vehicles should speed up/slow down/speed up/slow down. We do have treadmills of infinite length - they're called turntables. And they do NOT exhibit any of the behavior you predict. They exceed windspeed and do not slow down once they reach steady-state. And you can't explain why.

So, we can safely dismiss you as an ignorant crackpot.

So what powers the vehicle when above wind speed direct downwind if not stored energy ?
Wind can no longer power a vehicle at or above wind speed directly downwind

The answer I get to this is that is powered by the wheel on the ground.
My reply to that is any energy taken at the wheel will be from vehicle kinetic energy which means vehicle speed will decrease.
And putting all that energy from the wheel in to another wheel (more efficient) or a propeller will still reduce the speed as you can not output more power at propeller than you take out from the wheel since that will violate the law of conservation of energy.

Treadmill will not need to be longer just add weight to vehicle since the stored energy is finite and will cover friction losses plus it will increase vehicle kinetic energy. So a heavier vehicle means the vehicle max speed will be lower for same amount of kinetic energy.

Again I need to insist you look up my last question the one with 4 options as that is testable in fact I will provide the proof instantly not even need to wait for an experiment.

You do realize this is about the third thread electrodacus has created on this subject? He has been told to go forth and multiply by this forum twice before.

Do not feed the troll.
