I don't know if someone here knows Algodoo software... It can be downloaded here:

It's a physics simulator.
Well, I'm doing a simulation in Algodoo, and I am impressed how this thing I created never stops. See below how is the experiment:
It is a rod suspended on a hinge (which we can imagine that is connected to an axle in the third dimension). At both ends of the rod there are weights, which are absolutely equal (I used the tool "Clone" of Algodoo).
I just rotated the rod, leaving it almost in a vertical position, and droped it. It began to move and so far has not stopped!
OK, I have to admit that I turned out air friction, so it's as if the experiment were inside a vacuum chamber.
But it never stops! He turns to one side, then slows down and begins to turn to the other side. It is changing direction all the time. I used Algoodo feature to accelerate the simulation speed by 10 times, but yet it shows no signs of wanting to stop!
There may be a binary arithmetic error in the software - try your simulation on another piece of software.
There is no error. After a loooooong time (with 10x simulation speed) it's slowing down and almost stopping (but didn't stop yet).
I'm starting to think that vacuum chambers are the perfect enviroment to easily achieve overunity. With no air friction, overunity doesn't seem so difficult...
Maybe in a vacuum chamber, with no air friction, a dynamo may continue rotating for longer time, even with Lenz's Law, after the engine that made it rotate is turned off...
