Centrifugal overunity - An imaginary experiment

[vineet_kiran]

Thanks Mr.Vidar, you have taken lot of trouble to analyze the experiment.
Actually what I am thinking is anything once set into rotation should rotate for ever in the absence of any opposing force as per Newton's first law of motion.  In this system the opposing forces are,  friction between polished surface & point contact and also the resistance of  atmospheric air to the entire rotating system.
When piston moves outwards inside the tube it pushes the air out of the tube through nozzle. The momentum of air coming out through the nozzle accelerates the rotating system by Newton's third law of motion. This should provide enough energy to overcome friction between highly polished surface and atmospheric air resistance. (if you use several such tubes)
What happens inside the tube due to centrifugal force is immeterial because centrifugal force is imaginary or created force and not applied force.

Here is a crappy youtube video of the experiment. The analyzer isn't perfect, so there will be small errors in the simulation. I can repeat the experiments several times, and the results differ a bit between each try.


Enjoy :-)

The experiment proove that the further out the piston is the more the angular acceleration is. This means that the jet of air must supply that acceleration of mass with energy. Friction is not the main problem.
Look at the video. Without air jets the tube slows down due to the angular and radial acceleration of the mass / piston.
