Sorry everyone I seemed to have dropped the ball here (no pun intended)
I need to go over that last set of equations and see where I messed up.
Attached are the corrected results.

@Zhang Yalin
I do not see any extra energy from this system. There is inertia to overcome in the car when the weight is first released.

You should not add the weight of the ball and the car together. It's not right to do so.
If the power of the car comes from the other sources, how to add it ?

The car is moving when the weight falls due to the tension of the string attached to it.
If there were added forces on the car you would be able to see it.
Such as the string would go limp if the car is able to accelerate from added forces.
The reverse would be true as the string could break if the forces were suddenly forcing the car backwards.
You could make this system and when you release the weight try doing this at the same time drop another weight all by itself no strings attached and I would bet the free weight would hit 10m when the one on the string is only at 5m. Can you show a video of this system perhaps I am looking at it incorrectly.

If only you would contrast the ball with the car and the free ball 's dropping, then you will get it.

I do not think I will get it.  I guess I can not see outside the proverbial box.

You should ask your teacher, if what I said  is wrong,  I die.

@Zhang Yalin

I understand you believe in your idea, that is fine. However you have to make sure your idea works in practice and gives the results as you imagine in your mind.
This is an 'overunity' forum and if you claim something then you ought to show it in practice you are right. Calculations show you idea is not 'overunity' so if you insist on it is, then you have to prove it is overuntity.  It is not enough to state it on paper with words.

exactly, a real life working model should answer the question.

i have a feeling this system will not work but then again i can be wrong.

Thank you anyway. I am too poor to do it myself.

this should not be so expensive, just go to a junk yard and you should be able to find necessary parts to build this.

we all suffer, it's part of life. just hang in there, be strong or die trying. soon all things will be alright.  :)

peace.

Yes you can even double the speed of light but the car moves sideways by itself if you change it to water

so how would you close the loop here? how will this self reset to repeat its process? you're saying the generator will provide enough energy to reset the system?
Do water mills that use a gravity wheel to spin a crankshaft work the same way?  Is your thought experiment equivalent to a mill wheel?  Does the mill wheel operating on a stream or dam spillway exhibit OU?

REEDIT:

I'd vote for undecided or "Don't Know" on the poll.  I've never thought of the concept, but the law of conservation of energy may be at work here.  I'm not sure, though.

Ya simular to water wheel but leverage the water
by self leveling it the farther it goes the more leverage
the car does not self level
but beings were now off topic drunks kill
victims not due to the crash but due to energy
transfer there so wasted - ph when they hit a car they
are essentialy colliding the bomb
taking the positive energy from the sober people absorbing
it to the drunk the drunk lives sobers up the inocent die
so if you on opiates +ph and get hit by a drunk you neutralize
of course not counting other injuries this is why drunks live
in the wreck sad but true well figured id put that out before i forgot it

Can energy double?
If an iron ball weighting 10kg is placed on the edge of a table and let it drop pulling a toy car of the same weight from the top of the table, the frictional resistance of the car is 2kg. When the ball is about to reach the ground, the ball and the car both have the kinetic energy (10kg×10m-20)(20 by friction consumption), thus 100( potential energy) = 160(kinetic energy).
During the whole process, the ball travels vertically from the table top to the ground, while the car travels horizontally from one end of the table top to the other. If the car is attached to a generator set on the edge of the table, the colliding force will makes it work. And the same is true with the ball.
Some of the kinetic energy in the ball are consumed by the toy car so not all of the initial potential energy in the ball are converted to kinetic energy when it hits the ground. So the equation would be [100N -20N] x 10m = 800Joule, where the consumed energy of the toy car is 200Joule (20N x 10m). 800J + 200J = 1000J (The same as the weight of the ball falling freely for 10 meters). All the energy, no matter how you put it, are accounted for.

Can energy double?
With respect to this post and posted Reply #30,

Are you simply adding both the horizontal force of the car moving across the table and also the vertical force of the ball dropping?  If you can capture all the energy of both objects moving, I suppose you have a point.

But did anyone think of drag or inertia?  I think either or both would cancel the forward force acting on the objects.  "Conservation of Energy" as a concept comes to my mind, somehow.
