You probably be right like I said I don't have great knowledge of
electrostatic theory. May be I don't use the right word, what I
mean by charge is electron or hole (lack of electron) depend if
it's a positive or negative charge.

Suppose you have a toroid charged to some voltage. You

Yes at the first part of your question, I explain: If you take
the top terminal of a Van de Graaff, the belt bring small charge
inside the top load, the top load is at a higher potential than
the belt ( I think ) but the charge flow from the less potential
belt to the higher potential top load. The explanation I read
about it is the charge inside the terminal are push to the
outside by repulsion. In a way I think the same phenomena happen
in a toroid: Charge are moved by repulsion from the facing wall
to the exterior wall of the toroid more or less depending of the
shape and the potential of the toroid ( At the square of the
distance ????? and density???? ).

What I said could result of a bad comprehension of the theory,
this is not an affirmation, and if my comprehension is bad please
correct me.

No at the second part: I don't believe in free energy !!!!!

I don't know may be we talk of the same thing but my lack of
knowledge and my difficulty to come to grips with English created
a miss understanding.
