Ahh, sounds like an f&P
Build it and they will come..... in droves
sounds like the best conversation starter I've heard of yet for the campsite.
My suggestion is for a low wind setup.
Use a 60 series de-cogged and re-wired as you're not worried about top end and go for a compact blade setup,
1.5m rotor
Whats the plan for a mast? Windmills generally aren't a 20 min exercise to set up like a tent and should it come down......going to hurt!
If we are talking about something that could be permanently attached on a telescopic pole on the back or roof of a caravan, I'm thinking the noise will keep you up at night.
Sounds like a real challenge but and F&P will do the job.
generally they need to be in good wind sites with good wind to make 300W+, so as you'll have neither of these 50W is a great expectation to have.
A 50W solar panel makes more sense but probably wont work at night!
Luck favours the well prepared

I have a very efficient 12V fridge on my small sail boat and it takes just over 100W of solar panel power to keep cold (not frozen) on a longer trip. A few cloudy days and the generator must come on as well.
So, you are looking for a very windy site and a reasonably sized wind generator plus a decent deep cycle battery.
It may be better to consider solar and wind, rather than putting all your hopes on wind alone and it lets you down...

we have a 80 watt solar just wanted to try this out also a 105 amph deep and where i'm going is very windy the hole time so was an idea i am heading to steep point in WA

Rutland is a good thing but they are $1400 on ebay.....
going to need at least a 4m high tower to put it on too.
Very windy usually isnt VERY windy, very windy is a terrible place to spend a few days....

You are right, been sailing in Shark Bay often but not when it is too windy .
The smaller commercial units are your best bet but beware, some are noisy. A walk around a decent size marina would point out the quieter ones to you.
Still, its a lot of stuff to drag out there on that rutted track and then rig up securely. Maybe a fold down mast that attaches to your 4WD? As long as you are not planning to sleep in the car .
Good luck with the fishing, I prefer to do that by trolling from my yacht. Klaus
Hi folks . First of all I'm a complete novice in this game , and this might be slightly off the subject , but I have a camper van with a 100 AH auxillery battery which is only charged when plugged in to 240 volt . Is there such a thing as a wind generator / turbine that could be fitted to the camper van that could be charging this battery from the wind while driving (up to 100 km per hr ) Has this been done before or is it a dumb idea ?

Your last comment is the most suitable. Charge it from the car is the simplest/safest way.Village idiot...or... just another hack out of his depth
