One for the Electricians and engineers ...

Is there any reason why an Alternator could not be fitted to a CT driven by the trailer wheels ??
Has it been done ?

Just idle curiosity .... its a slow day today !!

Cheers and Happy NY

Gday,
Good thought but I reckon there would be better ways of generating power.
1. Solar panel.
2. Larger alternator on your car and charge your camper through your trailer plug.

Remember (asuming youve got conventional trailer suspension)
1. your axle doesnt turn....only the wheel moves
2. the alternator would have to be mounted to your axle so it moves with your wheel travel.
3.It would be mounted in the dust and water
4.What RPM do your wheels spin at compared to your motor?

Are you thinking along the lines of an old pushbike generator?

Cheers
Hairy

Reminds me of those generators on old bikes for the head lamp. Man they were hard work, and for almost no light output.

Hairy ,

Like I said its a slow day and the brain is active - Just wondered if there was a reason for not having one when you have a "free" source of motive power to run it ...

I'm still toiling with the idea of a wind - powered alternator mounted to the CT roof powered by the type of fan used as an exhaust in dog trailers and some older caravans .. RPM is the issue there but i'm sure a few cogs would help ...

When I retire I might give it a go ...

Cheers

Steve

It wouldn't be 'free' because the energy is provided by the forby engine whether it's driven by a belt in the engine bay or connected to a turning wheel.

Hmmm slow day here too!

Ian ,

I like the idea of the Hamster powered unit - Maybe we could design one with Cane Toad power ??

Seriously though there ought to be enough wind power whilst on the move to run a small fan and alternator setup ...

dreamtime - maybe later this year i'll get a prototype up and spinning ....

Cheers

Something like this?

If you search the forum archives you'll find I drew this in response to some one else's "what if" some years ago.

Yes, it IS a slow day...

what would you use when camped, with wheels NOT turning ??

Design a simple wind generator, using a small Alternator :)
