I recently read that caravan batteries generally only reach about 80% charge from the car. Giving this more consideration, a thought occured to me today. With self-propelled caravans being so common (i.e. a motor), why don't caravans charge their battery from their wheels (i.e. dynamo)?

I realise the motive power for caravan parking aren't designed to do this, and I realise attempting to utilse them in this way would be insanity.

Okay - forget the motors. But why don't they charge from an alternator or something coupled to a wheel? Either by belt of directly?

It's just an idea. But why not?
