Perpetuum Mobile

Just get with building VAWTs already. Sheeesh.

none of these could work because they would not be able to do anything except spin because they only have energy to spin and not anything else

they wouldn't even have the ability to spin without some outside source giving it power to spin. unless it was a frictionless world. but even then some outside source would have to start it, and the machine would only have as much energy as the original push.

Not even that, they'd stop eventually due to friction.

None of thease would work.
you can't make energy from nothing.

Yes you aim to high to want free energy just standing on your sofa.
Someone is doing the x-tra pushing already, gravity pulls, where is the nothing?  maybe putting two of those back to back little offset maybe it will spin more, and if it spins hard enough to turn a Seiko kinetic electricity generator maybe it will be a little more economic. "we hate efficent dinamics, we want perpetum mobile " ha ha ha

well... it could be your IQ...

basic concept of thermodynamics: You allways use more power than you can generate.

And a perpetuum mobile would have to generate more energy than it uses, IE, it would have to Create energy, which isn't possible.

It can't work because of A- both sides of the machine weigh the same, resulting in equilibrium, and B- Friction and drag on the axis will cause a loss of energy.

@BlackWarriorsFA
they would never work because of internal resistance. The resistance of the center pin would slowly bring thestarting speed of the system to a halt.
