Brad,

Really? Come on man (Joe Biden)!

What you are saying is nonsense with the gears theory.

This is another way you claim your geared car would work. Not going to happen Brad!

 

Yet, you are claiming you can do this with simple gears to move it forward using the same wheels that created friction and even accelerate it forward is just insane comment.

First of all, you might as well say you can move a car down the road without any motor.

Tom

You're not getting it Tom.
The air the prop is pushing against is stationary, so with the wheels and gears experiment, the drive wheels should also be pushing against something stationary. And like the propeller, the wheels on the stationary part of the treadmill, should also be driven by the treadmills belt, which is moving in the opposite direction.

Quote
As far as the car with the propeller, the treadmill moving the tires alone would cause the car to follow the direction of the treadmill plus the increase load of turning the propeller will increase friction. The propeller needs even greater thrust to over come these factors.

I find it hard to believe that you don't understand how this works.
We have the treadmill belt traveling backwards at lets say 10m/sec, and providing the car with energy, which is translated to the propeller that pushes the car forward at about .2m?sec

Your mistake is looking at the stationary treadmill frame, and not looking at the vehicle in relation to the belt.

But anyway, i look forward to seeing your OU device based around this effect.

Brad,

Instead of going back and forth and you're not willing to build your car prototype.

I see it different, let me explain what I really see.

If you take a turn table that is control with a speed controller and add the propeller car that moves in the opposite direction. Is it possible to lower the speed of the turn table where the car increases  until the turn table is stop and the car continues to accelerate? '

That is what I see in that video and I must built that next.

Instead of talking let just have a build off, just maybe we all can learn something new.

I haven't seen your prototype doing the same as the one on the video, just try to do a geared car going forward, while the tread mill moves in the opposite direction.

My opinion is you're nothing more then hot air with nothing to show.

My idea is to prove or disprove this could be over unity.

The rotating disk and the propeller car will either prove the car accelerate or won't.

4ft diameter turn table would be a good size to work with and a rod attached to the center shaft with a bearing. it could even be a sprag bearing where is will stay still until it accelerate forward.

My theory is the car will continue to accelerate to infinity or break.

Your theory is incorrect.
The vehicle will reach a maximum speed, where the propeller can no longer provide enough thrust to overcome the increasing friction that comes with speed.

See my setup below, where i will not have a propeller pushing against stationary air, but a gear driven wheel pushing against a stationary platform.
Bet i can get mine to go faster than yours Tom  :D

Let the challenge begin--i accept.
I think 4 foot for the rotating platform is a bit big though.
2 foot in diameter would be more than enough.
You set the RPM the platform rotates at, and we will see which car can do the most revolutions in say 2 minutes at a set platform RPM.

Brad,

I don't think so, but I plan to do 4' diameter not 2'

One thing that won't happen is the car going forward. the gear ratio is greater then the wheels, this is where the mistake happens all the time.

This is why the thrust worked in the first place, not physically attached to the drive gear system like yours.

Thanks for entering this build, maybe your friend will join too.

My version to test Veritasium test, does the car move even faster then in the video?

Are you saying my car won't move in my setup?

I have not tried, but i see no reason it will not move.

With the propeller setup, the wheels are driving the propeller, which provides thrust to push the car forward- (if we assume that the bed is traveling backwards). My setup is much the same, where the only difference is that i will be using a wheel to push the car forward, and not a propeller.

Ah, ok. You mean 4 inches.
I thought you meant 4 foot for the diameter of the rotating table lol.
Bloody Americans and there feet and inches stuff.

My rotating table will be about 600mm in diameter lol.

tinman,

My turntable is 4ft diameter and you went with 23.62 inches.....lol

I believe I have all the parts, so it should be a fast build.

The turntable design will add resistance as will different bearing choices.
 I would think you would be better to use a remote control car. Record the speed at full throttle or any particular throttle percentage. Then add fan blades and record the speed again at the same throttle percentage. Or record time taken to kill the battery without fan and again with fan.You wouldn't be adding any resistance other then the fan blades. 
 The turntable design will add resistance from the added bearing or what ever used for the center attachment used for keeping it on the table plus there will be resistance from the centrifugal force.

When are you guys going to catch up with the rest of the world, and go metric  ;D

Ok, so my table is close to 2 foot in diameter, as i had no 4 foot wide sheet timber to make one that big.

Here is my setup design video.

Hi Brad,

I will have my update today, my turntable setup with 3/4 plywood I have.

I want to thank you for taking on this challenge, it tells me there is hope in this world of people like yourself trying to build something instead of people who just talk BS.

This would be fun and no matter what happens maybe other can join in with other challenges to build stuff on this forum. It really got lazy with lots of chatter today.

My challenge is not personal, it's seemed like the only way to get people involved today.

Tom.

Mine is coming along just nicely.
Will have it altogether by tomorrow lunch time-if i don't sleep in to late lol.

Got the center bearing swivel all printed up, the swinging motor mount all printed up, the disk cut out, and mounted to a bearing head, and the outer running board is ready to fit once the motor is set up.
