(I will be posting a small conceptual video tomorrow by the way)
Well firstly i will be using neodymium as they are high power and fairly cheap.
To gain the maximum torque i will likely not be using ball bearings, but a liquid-based drag reducer, but i will get a professional opinion on which
would be the best.
The shell and supports will be made out of non magnetic material, whether that be some kind of strong plastic or simply non magnetic metal.
The finished prototype will have two sets of rings; each angular section you can see will be a separate magnet; there will be spacers between each.
As for the weight, see, this is why i was leaning toward using as much plastic as possible, for weight reduction, but the base
would have to be
either weighted or screwed down, as it will likely vibrate a lot.
Lastly G+S the power. Obviously i cannot say how much power will be produced, but if its not sufficient to power many external devices "live", then
i will look into firstly increasing torque, and if all else fails it will have a storage device that it would charge up overnight for example.
In all honesty im an inventor (no thats not a full time job

), im not an electrician so electronics isnt my forte. I have a good friend however that
is collaborating with me on the electricity generation and storage etc. Im just building the device itself and focusing on the workings of the PMM.
Storing or utilising that kinetic-potential energy comes later.
EDIT: oh sorry and specification/custom parts; my father is an expert in engineering, metalwork etc. and has access to the neccessary machinery to
build parts for a working prototype.
