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.
I've gone as far as 55 miles in one bike ride, and hope to do a full century ride someday. 30 miles is not at all out of the ordinary for bicyclists.
If I can do it after not riding my bike for a year, then so can you.
Thanks, I don't doubt it. Biggest issue is that I have significant anxiety about doing any riding after a really close call some years ago. A car was going something like 50 mph on a 35 limit street, and was inches from hitting me from behind. Technically it did hit, but only enough to barely whiff past my body, and put a small dent in my rear rack.
30 miles is laughably low. A single ride would drain it for me. To go to store it would take 10 miles, not counting anything else.
I recommend going to a closer store.
Why? For less convenient, choice, and worse prices?
A 10 mile round trip would probably take about 3 hours, it probably isn't as far as you think it is.
3 hours? How slow do you bike? I average 25 to 30mph on a non powered mountain bike. I could walk that in 3 hours.
30mph is incredible
Literally. Especially on a mountainbike averaging 50kmh is insane.
Probably own a speed pedelec. They average that top speed.
But then you could just buy an electric moped instead.
Says unpowered mountainbike in the post though. Can only imagine they meant 30kmh
Are you walking or cycling?
I work 18 kilometres away from where I live, that takes me 45 minutes on my acoustic bike. That's just a little longer than 10 miles. The round trip is ~an hour and a half
He's a student so he probably just doesn't know any better
I mean A middle school student should understand why this won't work, so not much of an excuse
Yeah you need to take basic physics in high school before even getting in to engineering school.
My distance to work is 12 km one way, so your battery would be empty afer two days...
16km for me and I'm not even leaving the city, this battery would last a day, not that I need it.
He's probably lying. While the bar is pretty low for entry level M.E.s, it's not quite that low yet.
As an old Toolmaker, I have made my share of intern wannabe MEs cry after crushing their idiot ideas. I swear, the older engineers would send those clowns to me just so I would beat them about the head and neck with a stick.
(I have a Daughter that has a PhD in ME. I warned her to turn down the free lobotomy offer upon finishing her degree. She listened and is now a happy and very, very smart Dr. of Engineering working with EV and HVAC systems)
Don't be so hard on him. He is still a student and got to learn.
