bernard240vdc: This exercise bike that I made would not directly boost a car normally but could charge a battery say several minutes pedalling might get you out o a bind and unlike a battery booster pack would not run down possibly
bernard240vdc: Hi guys there I also made a very similar exercise bike but instead of the scooter motor I used a car alternator instead,, very simple build a solid stand to hold a regular bike with the rear wheel off the ground ,, remove the rear tire and then run a long belt into the empty rim and also around the alternator pulley, this setup works just right giving the alternator just the right speed at normal pedalling speeds ,,, now a rheostat in series with the alternator field will allow one to dial how hard you want the machine to be to pedal alternator output can simply be sent into a 12volt battery and a ammeter will give you an idea how mucht power you are putting out... I myself tried this setup it worked just fine makes for a good exercise bike or even if you where alone no other vehicle available could possibly be used to get car going if by mistake you left the lights on or something and battery good but just drained
Jake Jones: Get rid of the chain and have direct drive to the generator. You will increase the efficiency. Also, the flexing of the wood frame, which robs energy, can be replaced with rigid metal. You've probably already made these changes by now.
daniel chung: ... It's a matter of time that we will no longer use coal or gas nor nuclear
Tony Boroni: one person can produce hardly nothing.
Edwin Dueck: For a gym that is a great idea, thanks for sharing your video.
Keepingittocool: That was cool.
Maher Ghazal: I would consider a flywheel to avoid fluctuations.
PoochieMan123: Use them for the spin classes and have those classes every hour!
Cynical Zombie: I would love to make something like this to help power my computer... problem is... I have a 780W power supply in it. =(
clnmyjts: tent city in Az has a bicycle generator hooked up to a TV if someone wants to watch TV they have to pedal the bicycle..( the generator must putting out enough to run the TV I was there and watch TV while same one else was peddling ) BUT I don`t know for sure if the TV was a TV than ran on 110 AC current or ran off of 12 DC volt. )
Jim Territo: So can generators be applied to "dumbell" style work- outs? And if you can do enough work in an hour to fully charge a phone, it would be worth it.
TimeEnergy Money: forget treadmill, indoor track with piezeoelectric devices under the track to generate power when running.
TimeEnergy Money: exactly, now we're thinking!
tbizone2002: awsome video, thanks!
Ivan Buratov: Good day! I'm Hannah.I did -35 lbs in 7 days.Visit aidadiet.com
Joe Joel: So how do we rate the video?
I say it is good.
Random Man: Hook that up to a 250 watt 24v Waeco camping kettle. My one boils 2.5 cup of water in about 20 mins = 83watts. Lay bets he could make a single cuppa in 30~40 minutes.
Random Man: Use a gearless brushless hall sensored 3 phase DC motor and an ebike controller with slipmode regeneration breaking. You charge the ebike controllers capacitors and turn it on with .6watts of pedal power. You can set the regen voltage switch on and switch off voltages with configuration software on some controllers. This is more noiseless and efficient and voltage current cab be controlled by the how much throttle signal you do not apply,
MidnightMarrow: I think with an alternator behind it with a belt on the rim with a proper gearing ratio it would have been easier to pedal more rpm's at an easier pace, Though you would need a battery to get it started.
