    Hey all,
    I am trying to source somethign simple to power a low wattage bulb in my shed (to save me having to run cables through the garden)
    Im not sure will I get the sunlight for solar, especially during winter, however we have a fairly constant breeze running down the side of the house (like a wind tunnel somedays) but all the wind turbines I can see are a) expensive & b) providing much more power than I need & c) large.
    any ideas?
    I see maplins have a solar powered shed light for £15 but its only 6 watt or something

    in general wind is better than solar (pv) not least because we get more wind in ireland than sun :)

    could you use some 12v lighting powered by a car battery and use wind to somehow charge the battery?

    yeha, I mean its not a big shed by any means, your standard 6ftx7ft if that
    I just dont want to spend a shed load (har har) of cash on something this unimportant, I mean I could just buy a torch...

    or just for the sake of it you could spend countless hours/hours pay building/buying a big propellor, an alternator from an old car, linked to the battery, which generates 220v ac through an invertor. just to power a 13W CFL :D

    possibly the least cost efficient project ever :) anyone want part of a 200 year return on investment.

    you know you want to :D:D:D

    Can you rig up something out of an old bike dynamo and a 6 volt lead acid motorbike battery? surely that would run a load of LEDs?

    yeah that would be perfect, now all I need is a dynamo, a fan blade and a 6v motorcycle battery :)

    Seek and ye will find

    Allyou need is a computer fan , an electric motor out of a toy car and a rechargeable battery (use an old mobile phone batter)

    Or go to maplin and buy
    a) a solar panel kit for lighting a shed approx 80 euro
    b) Lead acid battery approx 25 euro
    c) battery regulator 15 euro

    Well that is what I did...probably cheaper to run cable but I couldn't be bothered..
