Sowatup
I asked a while ago about this, but I there was still some confusion in my mind. My ultimate goal is to use power electric heating coil from human powered bike. I was wondering, I will I be able to create enough power to power the coil?
Here's what I have so far: I took the motor out from an old fan, and I was thinking about directly connecting that to the bike. My question is would that work? If so, about how much power will I be able to get out of it? Am I going to need anything like an inverter? or can I just connect to the two end terminals to the coil, and that would work? Also, am I going to need a diode? Basically, what I am trying to ask is how would I put everything together? I have bits of info, just need to figure everything out.
Also, as for the coil, how does the wattage rating work? I am thinking of using maybe like a teapot coil..
Thanks in advance!!
Answer
I have an old bike generator and it's rated 6Vac at 3W, so that's .5Aac. One watt of power is about 3.4 BTU.
You want to derive the maximum power transfer, so if your Gen happens to be like mine your need to calculate load resistance.
R=V/A R=6/.5 R=12 Ohms
Your heating coil needs to have a resistance of 12 Ohms. Now you could wind a coil of wire that would have that resistance. I can tell you how to do it. Or you can go to an electronic store and buy a 12 ohm moisture proof resistor. If it is always going to be submerged heating water, 3to5 Watt rating is plenty, otherwise make it 6Watt. Make sure you cover the leads with heat shrink tubing for insulation, its not critical because the voltage is so low. Connect the leads right across the output of the Gen and that's it. Pedal your bike and the resistor will get hot. About 10 BTU. If you want details on making a coil, email me. Good luck

Answer
If you are looking for a mini dirt bike I would suggest something from the Razor brand. They are electric powered so they're not as noisy. They fully charge in 8hrs, leave it overnight and you're good to go. They are very highly rated on average of 4.2 stars out of 5. If you're looking for a smaller version I would consider the MX350 if something bigger try the MX650.
