To me that is crap.

Solar panels have their place - in remote areas where laying normal power isn't an option and current usage is very low. For example at a remote resevoir for monitoring equipment etc.

A wind generator on a boat makes more sense in the UK. Problem is they will put out too much power for a RIB.

I know what the problem here is, the store is a standardised design Tesco used the UK over, the solar panels work in every other one except the ones in wales! its the weather thats the problem

Aye, but it would be your engine that was powering it.

Maybe it's my definition that's confusing. To me crap implies a poor product.

I have two solar panels, both approx 60watts, one on my boat and the other on my caravan both are connected through 3 stage charge regulators. The boat one is used primarily to keep the batteries in good condition and it does that without problem. The van is used for about 8 weeks each year and is self sufficient in power. To me, that's not crap.

You've just got to get your head around their characteristics and work within their limits...as you have to with other power producing systems.

Bugger thats my plans for a rib with an electric outboard and rutland generator that just needs a small gust of wind or a spin on the turbine blades to start it off, out the window

Isn't that a similar principal to the ramjet whereby the faster the speed, the greater the thrust to increase the speed to provide further thrust etc. You might need to strengthen your transom though!

Have we, by roundabout route, just hit upon ( dare I say invented ! ) the perpetual motion machine & therefore solved the worlds energy problems ?

The boat moves forward driving the big fan thing which actually puts energy back into the boat ! By jingo I think we might have something here !

Or have I missed something ...... oh yea petrol .

PS - this is my attempt at humour.

I actually know a bloke who has a wind generator fitted to his LandRover. It's an old Series II and the alternator was knackered so he attached one to a radiator fan on the roof - it does look seriously cool - like something out of Mad Max!!!

I saw that a while ago - it's amazing how many investors can be conned into such crap.
