It's an interesting idea but it must weigh a fair bit, and they lost me at 'simply turn your bike upside down...'
It takes power/ effort to charge things up so as the saying goes there's no free lunch.
What would be of real use is a regenerative brake so that you get your kinetic energy back when you accelerate instead of wasting it all as heat.
If it converts the rider’s weight into forward movement then presumably the rider loses weight as the bike moves forward otherwise it will break the “you don’t get owt for nowt” rule.
I know the 'owt for nowt' thing, but if the wheel uses the energy of body mass pushing down onto something static (i.e. that energy would otherwise go into tensioning a spoke), could that energy not be released as the wheel turns? That seems to be what the rotational springs are doing. It's not like you have to compress the springs with your muscles, your body mass is doing that for free.What saddens me is the level of scientific ignorance in society that enables this sort of thing to even get started.
E=mC2
A small amount of your mass is converted into huge amount of energy.
Akin to this?Yep that would be the best way to recover energy.
I'm surprised no one's made a rear hubbed ebike with brake harvesting yet.
If you put dissimilar metals in your collected sweat you’d have a battery.Yup, you sweat profusely trying to pedal that heavy wheel.
