Directorly Downwind Faster than the Wind

[Rapadura]

If the wheels of the cart were bigger than the propeller, couldn't the rotation of the propeller be so fast that would give a very high speed to the cart?

Just make the wheels of a very light plastic material and don't put a pilot in the cart, because humans are very heavy.

And make the best possible propeller, a very optmized propeller, that gives maximum thrust.

To test the device, there is no need for a truck pushing it, just suspend the cart in the air, and use a motor to accelerate only the wheels. The rotation of the wheels will make the propeller rotate too. When the propeller is rotating very fast, producing a lot of wind, put the cart in the ground and let it run.

If everything is OK, the cart will never stop again!

Thankyou for the links.
You seem to be a student of this work?

Where do you think this will take us?

I am not being facetious ,I am genuinely interested
In where this could be applied.

To hell with a propellor put a big old spinning frisby up there and wheels once she lifts off that turn into backward inclined turbine blades.  Adjust the angle of the Frisby to the direction of travel intended.  The low pressure created on the lift surface of the frisby gives it's ability to fly.  You dont throw a frisby to get distance without spinning it.

I am not a student of this work.
I haven' t any relation to this project. I only set down yesterday and did some simple research. So I have found this information. I thought it could be helpful for someone.

You ask where could it be applied? I don't know. But it is very impressive to see the little cart driving so fast.

Do you guys actually think that the wind is not needed to go fast down level ground? Free energy everywhere, you just need to want to tap it? Right?
If there is any free energy to be had, it's going to have tpo be in conjuction with gravity. Wind turbines are proven to work, just not without wind. All we see is a cart that can reverse the prop to get more speed from the wind.

If gravity's pull could be exploited extra by the prop cart (I can see it, but not believe it), then that might be real OU. Gently push the cart off a 5m tall ramp. If it goes faster than 9.8m/s at the bottom, you have OU, cart should be able to reset itself, ride up another 5m tall ramp.
In this little fairytale, the force of gravity is used twice : once to get the cart rolling, and once to make the wheel turn the prop to a higher speed than the cart's speed, beating the apparent head wind. <zero wind resistance, if you will. If it sounds too good to be true...
