how do you field the alternator?

[jaimemruiz]

@goyherder, i have to start spinning very fast to excite the alternator, so it start working, and then i can continue pedaling slower.

If you want the alternator start working without having to spin so fast at the beginning, you can use a 12V battery to excite the rotor when you start pedaling.

Do yo have a web page where I can find the diagrams of your generator? could I charge a 12 V battery?

[jaimemruiz]

ULE13, you can watch some detailed photos of my latest design, in world wide web * verdesypobres * org. It's in spanish, but yo can find the thread going to "Foro", "Energía y Transporte", and there click in "Bici con generador electrico". The main photos are in pages 6 and 7.

Yes, the easier use of this is for charging 12V batteries, that there isn't in the video, only to show that i produce the energy, not from the stored energy of a battery.

Please use your device to charge up a Taser so we can MAKE THAT DOG SHUT UP!

But all joking aside, your contraption is very interesting. I wonder if it's possible to mount the alternator and other equipment onto the bike itself and then use a double-sided sprocket (and of course 2 chains). That way, the bike can still be used for riding.

You could mount the generator over the wheel, and touching the tire, like the little dynamos used in usual bikes. It's very easy and cheap with a rubber over the pulley.

It could be very useful to recover the braking energy with an electric heater in winter, or a very powerful light in the night.
