Wind Power - nothing to do with baked beans

Keep in mind that any wind generator needs at least 20km/h of wind to generate useful power, so unless you are on the coast or on a ridge, it's unlikely you will have enough consistent wind.

This one needs 45km/hr to generate 400 watts.

$1200 is very expensive. Here is one for $500

I can't comment from experience on their particular effectiveness.
But you'd need to be careful on where you mount the generator. I saw one a whille back mounted on a pole clamped to the bull bar of a vehicle. Nice and sturdy, and I noticed it was fairly howling around, obviously putting plenty into the battery, but I thought that if a kid climbed up on the bull bar, decapitation was almost a certainty.
I noticed that Oatley Electronics was selling them as well, but they had something in the ad about an engineering certificate needed for erecting the generator on a guyed pole.
Just a thought...

Ian have used a smaller more portable unit attached to the van in conjunction with a single solar panel. Together they ran everything without the battery ever fully discharging.
Wind noise is barely noticable particually inside and could be turned off in a gale. When camping on the coast there was always a breeze to add some power as although 40kph may be the optimum wind speed it certainly doesn't need to be that strong to get some charge.
In a gorge or valley amounst trees I doubt their value would be great without a tall pole but for base camping along the coast or in open areas they work well, particually in conjunction with a solar panel.
The one I used was from WA Solar who could give you the full run down on the most suitable for your application.
