In this report – a serious viewer suggestion: We examine the viability of re-charging the caravan’s battery using a homemade wind power generator strapped outside the van, as you cruise. What could possibly go wrong?

I tow a Ford Ka behind my bus on an A frame, if staying camped for a longer period than normal and the batteries get discharged from my wife watching TV late into the night I charge the bus house batteries and start batteries from the car. I normally cant start the bus 5.7 liter diesel at a campsite but the car is quiet at idle The KA is connected to the bus anyway with trailer connections the Aussie trailer connector plug only uses 5 of 7 pins. Earth ind lhs ind rhs brake and tail lights. I use one of the spare pins on the bus there is wire from the plug to the batteries and on the car to the battery. Have used an amp meter on it when batteries have been pretty discharged and it never gets over 5 amps dont know why expected more but wanted less its perfect. I have seen it done "properly on caravans with an Anderson plug and heavy wiring good for them but mine works good.
John, may noy make much of a difference but most caravan fridges are not like the one you illustrated. Most are 3 way fridges that use the absorb method of heat transfer in lieu of a compressor of say 40w or 8 amps 12v. But, a 120 AH battery unless its Lithium based only has about 60 usable amps before voltage is too low. So an 8 amp draw will only last about 8 hours on a compressor fridge. The wattage on a 3 way typical caravan fridge is about 180 watts at 12v which equates to about 15 amp. That would exhaust the deepcycle battery in 4 hours.
I recommend powering 2 fridges from the windmill and leaving the door open on the second one so it provides free energy powered air conditioning.
It reminded me of the vintage SAAB cars that had the generator driven from the axle. As long as the vehicle was moving the battery would be charged.
I guy in the USA has built this as an experiment, and so far he has not gotten it do anything worthwhile: https://www.youtube.com/watch?v=MlwK4kCrXB0
Hi John , I have seen a report that both Ford and GM are $302 billion in the red between the two of them so the picture is not looking good for in the future.
No, even re-watching, I thought that was a waste of my time. RIP PJ's soft core as of Nov 20.
Where can I get a
M.A.L.S. Cap (2 would be nice). Much appreciated
