Does anuyone know where i can get hold of cheep permanent magnet generators
and gear systems for increasing revolutions un the UK? I can find a few in
the US but the shipping is almost as much as the generator its self.

I know of a group that is trying to increase revolutions in the middle
east. Don't know when they plan to start trying in the UK.

um i don;t think i  explained it correctally i was watching a program, the
other day and this guy (the 1 that invented the clockwork radio) just coved
in to a house down cornwall and to power his house or at least some of it he
built a water wheel which only only turned at about 60 revs a minute he then
attached that to a 1-44.2 geer system which was something salvaged from
another machine it was at least 10 years old if not older and then atached
tat output to the generator and i want to try something simalart just minus
the water wheel. at a push i know a few people in the dockyard that with a
bit of persuation could build me a gear system but it would be expensive but
the generator i know wuill have to be new but i have no idea what suppliers
there are.

You mean the programme "it's hard being green" ? That's not Trevor Bayliss fwiw.

He's not using a permanent magnet generator IIRC. There's a field coil powered
from a battery I think ( which then gets recharged from the outout of the
generator ). Probably just a normal alternator actually.

I have seen some permanent magnet alternators for home construction though. A
guy working on wind power in Scotland published his design online.
