I thought this discussion was about a device that was supposed to work by shielding part of a wheel from the electrostatic attraction of a highly-charged object...
*** Ok I uderstand you now. This is in fact where the original topic of this thread has reached.
So you said that in order to shield you need an earthed conductor and I agree that that might be one way but you need not 'completely' surround it in this case because you don't want all of the field blocked off.
If you wish to try the experiment but you find the metal shield cannot work it may be because a dense metal is not effective in this case since in my view it will tend to transmit the field even though it is earthed.
What I had in mind as the shield is a porous covalent/ non conducting material: I am thinking of ceramic material similar to what is used for spacing high tension electrical wires of electricity supply lines.
The theory is that if particles of the material are packed too close the field will transmit but the spaces between particles cause or assist in breakdown of the field inside the material of the shield.
A porous non conducting material should therefore be suitable for blocking out part of the field.

My point was that an electric field, which is the way we describe the way the force experienced by electrically charged particles varies in magnitude and direction in different locations in space, is not something which can be blocked in the same way as radiation, such as light.
*** You are right in that electrostatic field is not radiation and your concept that it is 'the way force is experienced' is good enough for experiment purposes.

To extract continuous rotational energy from a non-changing electric or magnetic field would violate Maxwell's laws of electro-magnetism,...
*** As far as I recall those laws deal with electricity ie current generated by moving conductors in magnetic fields etc so no need to fear violation of those laws, they are sound laws but they do not deal with static electricity which is what we are dealing with in this experiment.

... as well as the First Law of Thermodynamics.
*** If I recall correctly that law says that the energy of a closed system is constant. We are in fact dealing with a closed system with our apparatus but two things must be understood:
(i) Those laws deal with ke, pe and internal energy and nuclear energy as far as I recall. Even if you are talking of currents you are talking about ke of moving electrons and internal energy of heating. But they do not cover the energy of fields.
I ask: what is the capacity of an electrostatic/ gravity field? Like I explained elsewhere and any critical thinker in math or physics should be able to verify the earth's gravity field does work in keeping our moon in orbit yet for all the eons that they have been together the gravity field has not diminished from the tremendous amount of work it does against the accelerating mass of the moon for every meter the moon moves.
(ii) No consideration is given to the fact that the capacity of any electrostatic/ gravity field is infinity. So in our experiment the infinite energy we get from the device is consistent with the infinite capacity of the electrostatic field in our closed system for work.
{quote] These are really well-tested laws of physics, and a scientist who who could demonstrate convincingly a flaw in them would be almost guaranteed a Nobel Prize.[/quote]
*** I agree with that physics too it is solid but I am saying it is not all that there is. So if by flaw you mean that I have to find something wrong with those laws to earn a Prize then I guess I am out of luck. But if by flaw you mean shortcoming of the law in not extending courtesy to the infinite which exists then the Prize is mine/ ours because the capacity of the energy field/ substance from which matter is made is infinite.
