So I have had in my mind a lot lately about a self contained system whereby as you ride a generator is constantly recharging the capacitors. The reason I am using capacitors is that they charge faster and yes I know they discharge fast also. But if there is a constant source of electricity resupplying the bank then you could in theory travel indefinitely. Yeah I know, maybe a pipe dream. But the guy in the posted video shows his capacitor scooter, so at least it is possible to run an electric bike on capacitors. Now I/we just have to slow down the discharge rate i.e. regulate the discharge rate. Anyway just wanted to get a conversation started about this prospect or not. Basically what I am getting at is a better battery.

 
Batteries are just really good capacitors.
I had some fun with caps when I was in computers, I am talking caps the size of beer can and would would wide them with bare copper wire so if you grabbed it you get a nice jolt ;-}

Yikes :)
 
Generator off front wheel, recharging the capacitors. Motor on rear wheel operated by the capacitors.

hahahahahahahahaa! Got it.

Proof please: white paper, link, something to back your statement.

White paper disproving perpetual motion? Well science doesn't work like that way either. It's not up to me to disprove such a thing, it's up to you to prove it. Not being a smart ass, it's just that way.

That said, I will give a VERY quick answer assuming you probably skipped HS physics. There is no real "free energy", so from a start, energy comes from somewhere. Charged capacitor is a good example. So charge from home AC, fine. Set bike in motion, with your scenario - let me ask you - have you spun an alternator under load? Takes a decent amount of energy, plus getting you going and keeping you in motion on the bike. The power from an alternator to the motor via a controller is not lossless.

Answer: Friction and other (electrical) losses - ie the first and/or second law of thermodynamics. We have yet to find a lossless system.

This is impossible because of friction and other energy-dissipating processes.[
