Nice to get a moment to pull out a classic
honestly this probably works to some degree, just that you'll move at walking speed relative to the ground if you go up to the edge of space
I have never seen the Arabic language translation of this meme but I immediately understood it from having seen the English version.
This is satire… right? I hope it is
LinkedIn has been shit posting goldmine lately.
The amount of emojis scream AI generated.
OR hear me out, AI was trained on these kind of posts. Emoji were overused in similar fashion before the AI bubble. Remember when crypto and NFT was all the rage? Crypto bros were all posting like this. And it worked on gullible people, so now AI does it too.
It's funny how everyone thinks they're AI detectives now.
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.
Don't be so hard on him. He is still a student and got to learn.
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.
That's just regenerative braking on a bike. Without batteries.
In theory that idea isn't actually bad although I suspect in practise the mechanism would be extremely complicated and would be liable to jamming it in opportune moments. That said doing this electronically is already a thing, although not really in e-bikes.
pretty sure hybrid cars have regenerative braking - the car uses the motion to recharge the battery when braking, going downhill, or coasting
Why flip a switch when you can just let the bike sense if it is going up or down hill?
Would make hilly terrain a much smoother ride.
Then again, if you do all that electrical, you already just have an electric bike. Which is even more versatile on flat ground.
