Ok so I know this isn't really a inventor's site or anything like that (I dont have a place to ask) but there are enough smart technological people here that I feel I can ask the question and get reasonable answers on the subject. When I was younger I bought one of those shake flashlights and that's when I thought this up. I know that passing a magnet through a coil creates a current and that's the tech behind a Faraday flashlight when you shake it. My question is, what if you make the coil longer? Would that increase the amount of power gained? Its seems that you waist most of the shake power on parts that isn't a coil.
My next question is what if I was to make a coil that goes completely around a vehicle tire (one or multiple coils) with a magnet that travels through it entirely? Would the car then power itself? I know that centrifugal force would eventually make the magnet stop moving so my solution would me to put another magnet or piece of metal on the outside close enough to attract the internal magnet to keep it from moving. I don't know very much about this technology as you may gather but like I said, this has been an idea I have had since I was 11 and I have never heard of anyone trying it. It seems to me that if you have a vehicle that is a hybrid gas/faraday electric you would have a hybrid that you didn't have to recharge. Maybe its a stupid idea but I am curious. Thanks.
this sounds very interesting, I dont know enough about the subject to say for sure, but you should test it, get an arduino and some wheels and motors. hook them up witthe magnet thing and see if it outlasts the battery life.
A generator (permanent magnet+coil) with a permanent magnet isn't very high efficiency. The idea seems interesting at first, but it is impossible to create a Perpetuum_mobile as friction loss, electrical loss, loss in the magnetic field introduced into the coil, loss at batteries, loss at motor drivers, loss at the motor, loss from friction of the magnet and the tire, friction in the tire, friction between tire and road, friction between air and car, even the magnet you say you would put to keep the one in the tire in place would cause interference in the coil and eventually even out the magnetic field of the one you have in the tire... so you'll never be able to power a car on its own.
Your tire-coil / magnet idea is just a very complicated and wired generator like a bicycle dynamo... turn a magnet inside a coil...
ok, I just wasnt sure how good it was. Didnt they recently start putting this type of tech in the ocean to gain energy from waves? I heard about it but never really read into it because I was busy at the time and never went back.
I know of some versions... like underwater "windmills" aka. turbines; and many more exotic approaches that I can't explain in English... not at 00:30AM XD
But creating electricity in 98% has something rotating around or in a coil involved. Exceptions are chemical reactions, piezoelectric effect, solar cells which are not mechanic.
what about Faraday tech mixed with heat generators? ;) Like the ones used to charge phones by the campfire? Yea at this point I am seeing the downsides to it but I figured that the Faraday tech would have gotten better over the years with less friction involved with little to no wear. The magnet doesn't actually have to touch the coil so I kind of envisioned something like the mag-lev thing happening...or Pressure generators, where when they're pressed down it generates energy? This conversation is pretty fun, im not trying to sound trollish but I would think you could have something more efficient than sticking a battery in a car and recharging it like a barbie jeep.
You can't trick physics, no matter what kind of system you'd build it requires more energy to keep in motion than the amount of energy you can gather from the body in motion - so to be able to generate sufficient energy to move say a car you'll always need an external powersource like gas or batteries.
