Today I saw a Western Electric,1940`s (in working order) Magnito hand crank generator for sale. Would anyone know if you can hook up an appliance to it, say a washer and crank away?! I`m not sure how it works,lol. That would be creating some intentional energy! or if a generator of this type would be useful in the future? Is it possible to charge say a car battery with this generator? I was thinking car battery for electric fencing for animals. I know there are solar chargers, but we might not always have sunny days.
It`s on my local auction site for $50.00.
I tried to get info online, but did`t I couldn`t find anything on how it works.
This generator you're talking about sounds great. It does make a difference if it's AC or DC and how many volts but in any case with the proper converter it should be able to charge a car battery (or deep cycle 12v lead acid battery preferred. Deep cycle batteries can be discharged 50% or more of their capacity and recharged with minimal damage whereas a typical car battery can only withstand minimal discharge or larger discharge for a very short time before it's toast)
I've been looking for something like this that's mass-marketed. You would think with all the prepper mania out there it would be easy to find but this is about all I've come up with:

Build your own bicycle powered generator, or apply those same principles to build some other type of human-powered generator. The site seems to have changed since I last looked at it to mostly include videos now. It had order links for all the component parts, you just have to have the money and the wherewithal to put it together.

A 1 or 2 amp 12v hand crank charger. Better for small electronics, I suppose it would be possible to charge a large 12v battery with this but it's going to take a pretty long time and you'd be pretty worn out. Better to find a way to attach it to some other mechanism, i.e. windmill, water mill, bicycle, etc. It says $40 to order them from the company but they were on amazon a couple years ago for $25.

The freeplay WEZA foot pedal generator. This seems like it, the thing we've been looking for. But it's been discontinued! All attempts I've made to actually order one have led to dead ends, and since it looks to have been a few years since it's been manufactured, any that were still around would probably need the battery replaced since dormant batteries have a shelf life.
It's not too tough to create a current by just moving a motor to charge a battery but to do it right and on a larger scale you need all the proper components i.e. blocking diode so the battery doesn't move the motor, charge controller so the battery doesn't overcharge, mounting equipment, etc. Something like the WEZA that could work like a sewing or organ pedal could sure come in handy. But although it relies on the sun, a solar panel to at least maintain a charge or trickle charge a 12v battery can be gotten for pretty cheap.
Added re: LQB's post: yes, output specs make a lot of difference for this sort of thing. Someone who knows what they're doing could modify things to fit a specific situation but you'd be better off with something that already fits the purpose you're looking for.
