mechanical engineering student

Did not pay much attention in high school

When the battery runs out, you pull over and "pedal" to recharge the battery, then you're good to go again!

Nice to get a moment to pull out a classic

This is satire… right? I hope it is

I had this exact idea... when I was 7. That was before I was introduced to newtonian physics.

Looks like it could even be AI style with all the emojis.

Either way, thanks I hate it.

This guy apparently doesn’t understand the first and second laws of thermodynamics. However, in his defense, this is sorta how regenerative braking works, but with less complexity.

Mechanical engineering student huh? Good to know he didn't attend class on day 1 of dynamics

Wow, excessive emojis and em-dashes... Not ai at all

Either he's lying about being a mechanical engineer or the barrier to entry to become a mechanical engineer is embarrassingly low.

It this guy seriously proposing a perpetual motion machine for the purposes of EV charging? Also not that it really matters but who the hell has range anxiety on an electric bicycle. You get 30 miles out of those things easily, what sort of bike rides is he doing where you have to recharge that more than once a month?

He should try recharging a solar panel with a light powered by the solar panel. Just achieving infinite power.

Why not cut out the middle man and directly charge battery 2 with battery 1? Switch and repeat.

Newton? Never heard of him.

With this many emojis and em dashes, he's probably engagement farming using llm content, regardless of the thermodynamics gaps in logic

This is dumb as shit ofc, but it gave me an idea that's probably nearly equally dumb as shit:

Regular bicycle, but with an extra gear that can selectively connect to the chain or wheel or w/e, that's connected to a coil torsion spring on a kind of ratchet release.

Basically you flip the switch when it's a good time to rob some energy like when you're on level ground or going down hill. That energy makes you a tad less efficient (but you don't care cuz it's level or downhill), and uses that energy to wind up the coil torsion spring up until a max amount of torque is stored.

Fast forward a bit: now you're approaching an incline, so you flip the switch the other direction and that torsion spring regurgitates that energy back into forward motion, giving you a nice forward burst when going up a hill.

Not free energy by any stretch, but a strategic use of what you're already spending.

Feel free to explain why this is a horrible idea - I'm about as far from a physicist as it gets.

This has to be a parody account right?

Seems like satire to me. Pretty funny too.

It's almost as if one object perpetually moves something that creates a form of motion perpetually to continuously move that first item. Like a continuous motion machine or perpetual movement apparatus. Something like that. I feel like my naming is close, though.

Techbros rediscovering old principles, a tale as old as....well, since the tech industry.

This guy is only telling us part of the truth. You actually need three batteries. The third battery is hooked up to a solar and wind generator. Only then can you achieve true energy independence.

So you're on your ebike, going 15mph. Using 140w or so. You're spending 15-20w on the drivetrain, and the remainder is entirely aerodynamic drag. You're putting 120-125w into making wind move. You're also losing 5-10 watts to the drive electronics and dashboard. So your total power use is 150w.

If you're going to recharge a battery. In the same time it takes to ride, you need to get at least 150w of power into another battery. Sadly, batteries don't actually "just cleanly charge" there are some losses, but since we're going to take an hour to charge it, lets call it 5%. So to fill up that battery we need 157watts of input power.

Your bike, moving at a steady speed, is absorbing 150w of power. If we want another 155w of power, where is that going to come from? If we take it from.. say.. the front wheel, we are now absorbing another 155w of power. So to maintain the same speed, we now need to push the bike along with 305w of power. And.. now we need a bike that makes 305w of power, to go the same speed we were going with 150w. .... And we're only generating 155w.

There is no free lunch. If you're doing work, you need to get that power from somewhere.

don't forget to add quantum tunneling between the batteries for extra efficiency
