Can energy triple?

It's obvious that a ball that falls pulling a car will fall with much less speed than if it was falling freely, without pulling anything.

With less speed, kinetic energy is less. The kinetic energy will just be "shared" between the ball and the car.

The energy can't triple, It'll only increase a few energy less than 20J.

E=Gh=mgh=1×10×10=100J

Hi,   if you mean the above result (100J) is the answer for my earlier question on "How much work should be done to lift the ball up to the same 10m height",  then your previous energy gain of 60J is not enough to return the ball for a restart.  Now what?

80×2-100=60.

  So your resulting gain is 60J  and you need 100J to lift up the ball for repeating the process?

a simple test can do done by getting a piece of rope, attach equal weights (one weight should have wheels) to each end of the rope, then wrap the rope around a rotor / axle, then have one end of the rope that goes vertical and the other end horizontally like the graph suggests. just measure the rotor / axle output. if the output of the rotor / axle can pick up the weight of the ball to reset the system then we have perpetual motion.

EDIT -

EDIT - Actually the output should have more than enough strength to also reset the weight with wheels  and not just the ball or it wont work

Oh, No, It can't be changed, or it will not do.

The device can't be changed, otherwise, 100=100.

Unfoturnatly if the mass of the car equals the mass of the falling weight
There will be no motion at all. Friction will prevent any movement.
Look over the calculations in the attached file. Note I did not add the
Account of friction that will be present in the pulley guiding the string so
The losses will be higher. I would suggest you to build it and try it out
I think there is a lot to learn from trial and error.

No, you're wrong in the last step.
The ball and the car have the EK(80J) at the end.

the weight going horizontally must have wheels...  :)

Of course, it has wheels.
