    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.

    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.

  7. If you can't be bothered to communicate your question clearly, why should anyone else feel
    the need to give you a constructive answer. The way you posed your question gives us leave
    to wonder if you truly know which end of hammer to hold.

    It's more the case that I couldn't even begin to work out what on earth you
    meant !

    Before you completely jump out of your pram, see my other reply.

  9. How big do you want? What voltage and current rating?
    You can use an automotive heater fan motor, an automotive radiator fan
    motor, or even a permanent magnet starter motor.
    A windscreen wiper motor also works, and has a built in gear drive -
    as does a power window motor if you are looking for low voltage and
    relatively low power output.

    A treadmill motor works for higher output voltage and power.

    i;m looking at anythi g that gives about 12 volts at 3 amps but higher is
    better as i want to start with some small tests around the home but move on
    to using it for several things at once whick means i will need it to
    produce more evectricty as i start to use it for more things i can always
    not use it to it's fll potential at first but if i want to expand then i
    don;t want to have to get anotther after second hand ones are a good iea but
    ut us hard to get secondhand parts over her cause all the working ones are
    usually whiped up by rtepair copmpanys and as soon as they are available.

  15. For 12 volts you want a 24 volt or higher DC permanent magnet motor. I
    have a few DC servo motors that would do the trick, but they are in
    Canada and pretty heavy. Tape drive motors like the Ametec units also
    work good and were widely available as surplus. Your best bet,
    currently, is likely a treadmill motor, but if you are in a 2220 volt
    area the output will be higher than 12 volts!!

    Ok - I didn't recall the name exactly.

    Yes, that's the one I had in mind. He didn't invent the wind-up radio though.

    I didn't know about that. Thanks for the link.

    The programme's been very interesting in many different ways.

    LMAO !

    Surely you mean A-level ?

    What did you think this was ?

    Looks to me like a concise request for a clarification.

    Good communications ability is a vital skill btw. Ignore the need for it at your
    peril.

    ok I will aploagise for the fact that I got the wrong person I only found
    out about the program cause my counsin mentioned that he was watching it all
    come together as he lives about 5 mins from the farm.I have found that he
    didn;t invent that but he was on scrapheap chalange and I shuld have
    remembered him from there.

    I have just purchased the acompaning book that has more detail about what
    they did on the show. It is available in hardback and paperback, the
    hardback that I bought was £11.99 i think and that is reduced from it's full
    proce of £18.99 and that was from amazon.co.uk

    My comunication skills are improving sligtly I have only taken english at
    gcse level (I did progress to college on a microcomputer course) and I must
    admit that I did do porly in my english exams but at present I am not in any
    state to go back into education for that though I am working towards it.

    Thank you very much for that information I will take it into consideration
    if you do find any more information or anything else I can use I would love
    to hear.
