    I went to a house a couple of years back, the address was 'Mill Farm Close' (so a bit of a give away).

    It was a semi-detached house, and dead on the join of the two houses was the original water feed to the mill that used to be there.

    So they got together and fitted a water turbine - it's only 2KW - but it produces 2KW continually, no matter the time of year.

    They share the power between them, and if any is 'left over' it's dumped to storage heaters in the bed rooms.

    The small amount of power isn't worth selling back to the grid, who don't pay very much.

    In each generation it will need to be rebuilt twice. £700 with inflation.

    Yes and as someone who has family who work in the public school system and teach science classes I can say for certain your demonstration is a pretty poor example to learn from given whats required to make it work for what it shows in the end.

    I dare say it's the key point many of us have been pushing here from day one. Your device does demonstrate a basic principle but it does it poorly and you justify its validity even worse. :(

    Here's just one of countless better demonstrator kits most an kid can see and understand the actual working of through first hand hands on play.

    Now where did I say it was a Chinese motor :D. Your right though, thats if it actually lasts more than a year or two. One of our solar panels (water heat type) only lasted six weeks! But that had more to do with me trying to learn Golf, bloody stupid game.

    in the mean time I have finished model no 4.

    Tcm it is a nice layout, I like "the old style things" , but now the kids are playing with drones .......so to have a little atention probably I will start with this model :

    ...........
    my device .....I am looking for an aplication regarding the magnetic flux generated by a neodymium sphere at high rpms. It is something what I am looking more important than a generator...... I wish just to improve the layouts educational purpose , not to go further....electricity is cheap for the moment at least in my country is 0.104 euro /Kw

    fidget spinner generator no 5 using a neodymium sphere 30 mm + three neodymium spheres 13 mm as weight for the spinner + the old coil iron less
    thx st

    Notice how you have now proved what i said at the start ;). There was/is nothing special with the magnet etc or the set up. Your variations show it will work in many many forms, its a shame no one can come up with a name for a machine like this :rolleyes::rolleyes::troll:

    Sorry just noticed the red blue battery sitting on top, the one with no wires on.

    .....I wonder if I should apply 2 stroke chainsaw motor to that project board and then wonder why after starting up the beast, every one runs away.... hmm, a shame really, it made some quite impressive power before inertia claimed addendum and it made orbit.

    However on a more ideal note on this type of configuration, if you wanted to apply power output disregarding drag and friction to a point of greater reduction, then you would have to design a vacuum chamber with sealed wire ports for connections and an internal platform that sustains the spinners angle and polarity to start and then observe the results in length of how long the spinner would rotate.

    And that the array of internal parts would need to be close for optimal transfer / minimal loss.

    Would be an moderate/lengthy term commitment in development cost and unforeseen factors to an greater end on larger scales.

    : Edited : might as well add this in now.

    Of course then there would be a problem, the rotation of an magnetic field would still disrupt the time of rotation by halting the field produced by rotation eventually, few minutes typical spin time unless the size of a car wheel 18" or so spinner is used... Surprise the results would be identical. Or close enough unless the vacuum or magnetism is altered a bit.
