    Has anyone made any gadgets employing the shaker torch principle (not a torch) source of power?

    It has taken off in a big way,because it makes a light anytime anywhere without having to be concerned whether the batt's are flat or have corroded the torch.Also only two moving parts to wear out.Nearly every CE factory is making there own version. Best version I have come across so far is available in Tesco's for a £5,well made.Good value for money.JFEG

    The main thing about this type of generator is it is cheap, emphasis on cheap. A small DC motor hand cranked with a lever will produce a lot more power, with less effort. Shakers are very inefficient.

    If you want to make one it is simple enough (goes back to being cheap). You might even be able to boost efficency by make a bunch in soda straws and paralleling them, making sure they aren't so close they try to stick to each other and not move freely though the straw.

    Audioguru- I have one, decided to fully discharge it to see how long it would take it to charge; it does not. Two lithium coin cells, non rechargable. Each shake would produce a weak flash. Good magnet.

    MIT has come up with a development in their GenShock. Apparently they use the principle to make useful amounts of electricity from the motion of the suspension.
