There was this browser game (on the BBC website IIRC) with a Wallace and Gromit theme, in which you build stuff.
It had a level in which you make a vehicle-ish contraption and see how far it goes ^[or more like whatever contraption you can make to get the dummy to go as far as possible. Could even be a cannon, launching the dummy.]. I managed to setup a motor and generator in such a way that it effectively increased the vehicle's range by quite a bit.
I don't remember well enough now, but I think the generator didn't give as much resistance as the energy it was creating.

He must quickly Patent it and get venture capital funding for this brilliant idea!

Yes, many electric bicycles power themselves while going down hills or costing. As for the other idea that you could recharge them just by pedaling ... That exists already. Almost nobody wants it because it's easier to plug your bicycle in. The point of the electric bicycle is to do less work, not to do more. Otherwise you would get a regular bicycle because it weighs less.

I cannot facepalm any harder. Dude that's some 8yr old question shit

I mean... regenerative braking is a thing.

My hybrid Prius C had this, and yes, you actually can build up some useful amount of charge from just rolling down a decently large or long hill, and you can also run the car on pure EV mode, though you're probably not gonna top 20 mph on a flat road.

Obviously this does not create an over unity situation or perpetual motion machine, but, if this guy can figure out a way to put a regenerative braking type device onto an E-Bike, or maybe motorcycle/moped, in a way that isn't stupid expensive...

That could increase overall range, and I think it would be neat.

Though I... don't really know why you wouldn't just use one battery for the whole system, just have a modulation/regulation system for it.

It's not free energy, but there's at least one bike called the Pi-Pop that works this way in order to spread the energy demand from hills across more distance for the rider. It's an electric bike you can't plug in, it only charges from moving

Fun fact, similar tech is already widely used, in gas cars too, that's how the battery is charged :)

If he removes battery 2 and charge directly battery 1 (as it's pointless either way and adds weight) maybe he can figure out what's wrong.

Or it's ai slop.

Has to be a joke
