I had this idea 30 years ago lol. Bicycling in headwinds in windy and flat Denmark gives you a lot of time to think of dumb shit like that, like what if I put small wind turbines on my bike which generated electricity to give me a boost?
We've had windmills as part of the landscape here for a long time after all, so it wasn't exactly rocket science to think that one up.
Unrelated, but the pedaling cadence people have on ebikes bothers me. I'm always seeing folks in a high gear slowly pedaling. I'm like dude you're sacrificing watts! Pedal faster on a lower gear, you'll use the same energy but go faster.
You get into the habit of just ignoring the gears because it doesn't seem to make any real difference. Sure been in a lower gear is more efficient but it doesn't feel any different so you don't think about it.
I am not well versed in modern electric bikes. Do they offer regenerative braking yet?
Unironically, I would enjoy a bike that I could pedal at a constant speed, charging the battery all the while. Give me a display that indicates my pedaling speed so that I can tailor my exercise and you’ve created a moving stationary bike. I hate having to stop at lights and whatnot, so a rotation-based stabilizer would be nice at speeds below 10 km/h as I pedal the equivalent of 30.
Really, it’s just unfortunate that the engineering doesn't work out for momentum->chemical energy unless you’re biking at a professional level and willing to cruise slowly or charging the battery at home. Bleh
At this point just cut the middle man and have battery 1 directly charge battery 2, then reverse it when it's done. Same results with way less hassle
You could harvest energy from going down hills and braking, but that’s probably not work the weight.
For each second of using regenerative braking, you can accelerate for 0.7 seconds.
But how much do you actually brake when riding a bicycle? That's completely neglectable (at least for me).
Electric cars already do this and I'm sure there are some smaller electronic mobility devices that also do regenerative braking. It's not exactly a new concept.
I have a better one: charge from temperature gradients as it moves through new areas.
Fun fact, similar tech is already widely used, in gas cars too, that's how the battery is charged :)
He must quickly Patent it and get venture capital funding for this brilliant idea!
🤦♂️
I cannot facepalm any harder. Dude that's some 8yr old question shit
It's not free energy, but there's at least one bike called the Pi-Pop that works this way in order to spread the energy demand from hills across more distance for the rider. It's an electric bike you can't plug in, it only charges from moving
There is one particular mine, I forget where, and they extract ore at the top of the hill and carry it down in electric trucks that gather more energy on the downhill run than they need to get back to the top when empty, so they never need to be charged.
