Downwind Faster than the Wind #7

Explanation: The force on the driven wheels has finite torque at a very finite speed. This force is transmitted to the prop via an (efficient) gear that acts also as a fixed ratio torque converter to turn the prop. The prop converts this torque into thrust with a NON FINITE speed which, in this case, the car being super streamlined and light, is just able to propel the car faster that the power wheels. Q.E.D. or twoddle?
It's that or the treadmill is sloped!

In some of our tests the treadmill is level. In others the treadmill is sloped so the cart has to CLIMB the incline. The thrust from the prop is definitely not infinite, but the prop is immersed in a moving fluid (the tailwind). This provides the necessary advantage.

Sorry for my sloppy English... meant to say the thrust of the prop is 'not finite' ( ie. the speed range over which it applies power is wide.)
I sort of agree about your apparent wind theory too. I'm the guy who sailed the schooner for many years, so I KNOW we often used to sail downwind faster than the true wind, if light, just like a decently designed and well sailed catamaran or flying proa will will.

I've seen that the treadmill is more or less leveled in other videos, but you do not show the same fact in this video.

Since I am pretty damn sure that the phenomenon is not caused by what you believe i would suspect something along the lines of the treadmill not been leveled in this particular experiment.

We're pretty sure the phenomenon is caused by very well known and well described aerodynamic principles. If you think the secret lies in having the treadmill not level, how do you account for all the other videos in which it IS level? This one is clearly going UP a small incline.

Oh ye of little faith....
Thou art a doubting Thomas

please stop wasting your energy on proving that it is not a hoax and concentrate on the actual work :-) As a future engineer I am very interested in the experiment, and would like to see the cart running on the thread mill in a much smaller and confined space e.g. a box surrounding the experiment. I am curios about how much turbulence the cart can handle before deceleration occurs. Make it transparent so we can see the outcome. Smoke is a good indicator and be included. Thanks

deceleration? Whens the last time you fly an airplane and it starts decelerating?? That's dangerous logic. Airplanes decelerating = crash

When airplanes experience great turbulence, they do in fact crash.
