During shrinking, the magnetic pressure is only directed radially inward on the sample. Since there's no axial pressure, the sample would assume a squeezed cylindrical shape that would allow material to be extruded out each end of the solenoid, relieving internal pressure long before sufficient pressure for fusionc could be achieved. It takes an incredible amount of force to cause any significant quantity of hydrogen to fuse, such as an atomic bomb or the weight of the outer layers of a star... :^) Best regards, -- Bert --

It might be possible to configure the coil into the shape of a ball, but the practical problem then becomes one of holding off the voltage stresses between overlapping turns as the coil begins to expand from magnetic forces. A simple helical coil distributes this stress evenly across the turns, thereby avoiding premature flashover across turns. Unfortunately, it only develops radial compression forces on the -- Bert --

If the tips of the cone were placed inward with many others cones also tips placed inward I would think that the maximum crushing force from the magnetic fields of all the cones would be the center of the tips. I say this because the magnetic fields emminating would not be just in the center of the coil but in all directions. Also to have the magnetic fields of each coil not be pushing the other coils away. what would happen if a diamagnetic material separated each of the coils from the others. please understand, I am speaking from ignorance here for I do not completely understand diamagnetis materials. yet. Do they absorb magnetic fields, divert them, reflect them or what? If you have any information of this or know where I could get it, i would appreciate you passing it on to me. I am also curious on whether any studies have been made on whether the coins (or other material crushed is crushed to a smaller size and then springs backed to normal molecular size when the field dissipates. I am not suggesting that this be tried with hydrogen since I don't believe the result could be controlled, at least not at this point. It is easy to see that if the magnetic fields produced by the coils (as you use them presently) might be capable of longer working(?) times if they could be contained. Could this not be done by containing the coils with a stronger material surrounding them with possible a diamagnetic material being used to insulate the magnetic fields created from one wire to the adjacent wires of the coils? Forgive my ignorance in this matter but I would feel this should deserve much further study if such is not already being done.
