Hey Guys, I came across this in my random internet searching, it looks pretty cool and the price isnt to obscene. I won't go into the details, the FAQ on the website can explain it all better than i can. I personally like the idea, and think it would be a really good backup gennie but someone else on here may bemore familiar with the technology. Look forward to hearing what you guys think seftonmotors.com/Cheers Reth

I bookmarked them a while back, I really like the idea of a low-tech engine to use as a generator, they are relatively quite as well.
When I've got everything else done I plan to research this some more, there are a few around but most of them are too small to be useful, just designed for classrooms etc, but this one is around 1kW IIRC.

They will need to be big to get decent output.
I remember seeing an article about a company that made them in the 80's I think. Cant remember much but will try to find it and post a link for you. I looked like a slightly bigger sized gennie. I don't remember the Kw output but it never took off. Solar and wind are still your best bet I think.

I recently found these guys as well www.stirling-tech.com/They appear to have a mature product and sell world wide, but I've not looked any further yet. Obviously I'm a big fan of solar having lived on it for 14 years, not so much for wind as the turbines are noisy and anyway we don't get that much wind around here I think. Maybe one of the newer vertical designs or something would be ok, but if not then for a backup it's back to a motor of some sort and the Stirling doesn't need fuel. I suppose in the end a gasifier is the same in that you are powering a motor from wood.

I have read quite a bit about these, quite good machines. The other option I would look at would be one of the old 5 stroke engines, the do 4 rotations just on the power of the flywheel and then one combustion stroke. You would need to contact some antique engine people for one though, and they would not be cheap.
