"An Ireland-based entrepreneur is claiming to have invented a power-assisted bicycle wheel that doesn’t use batteries, doesn’t need charging, is not speed restricted and has an infinite range." AKA Perpetual Motion
- elliottkember 6y agoWell, a spring is a battery. You charge it by compressing or stretching it. I think this battery stores vertical motion - from when you first get on, and maybe if you go over bumps. But the "infinite range" thing is nonsense.
- Talanes 6y agoIronically, about the only vehicle that actually does meet all those criteria is a standard bicycle.
