This makes me scratch my head.... I see it but it can't be perpetual

As long as friction exists it can't be "perpetual"
Cool never-the-less

 
Just finished watching. OK Bas here's my question to you 4 or 3?

For years I've wondered about the possibility of a vehicle that would run off self-charging electricity - using its momentum to run a generator/alternator.
 
They have them now. BMW has the ultimate supercar. The more you throw it around the more it recharges itself. Had Clarkson driving it and when he drove normal, had to be charged. Drive it like you stole it and all the kenetic energy kept battery up without having to charge it.

Ah, well - guess I missed my chance to invent the ultimate!

You mean something like this Mickey?

Very cool demonstrations of almost perpetual motion machines. Some clever concepts at work for sure. The practical issue with them is as soon as you add in any sort of drag (for energy harvesting), everything falls apart. Definitely cool for coffee table demonstrations, though! Classrooms would get a lot of use out of them too.

What about adding a paddle wheel under the stream of water in the first example. The paddle wheel could be attached to a small generator. I would think the water would continue to flow.
 
This topic reminds me of this - remember?

or ... the Crookes radiometer!

Funny. I got a dippy bird just like that except a yellow hat for my daughter's birthday when she was about 5. She had to have one because Big Bird (Sesame Street) had one. She still brings it out for her birthday every year about 40 years later. Had to reflock his head a few years ago to keep him "drinking." Also got her a radiometer a couple of years later. It's right here on my bookcase but doesn't work anymore. Thanks guys. Those brought back some lovely memories.

Theoretically, but the paddles would have to be very small and spin very fast, probably faster than that stream could sustain, and it still would not generate much energy. No numbers here though so who knows!
