*Critically, during the compression stroke the noble gasses are not in a conductive state. The helium atoms are likely very thoroughly mixed, although I'm open to arguments to the contrary.*
In the John Rohner cycle, he first excites the noble gases with a radio frequency generator before the piston starts to move into compression. Xenon is easy to excite because it binding energy is low: many orders of magnitude lower than H2. The RF also produces clusters which strongly interact because they have good dipole characteristics. *Moreover, when I talked to Bob, he said that the current through the coils was very low. I don't recall what the current was, but to achieve significant magnetic confinement you need high currents.* The coils are not used to compress the gas to the state of fusion as in standard fusion technology. Their purpose is to keep the plasma just off the sides of the cylinder and away from the compression rings. These modest requirements don’t call for high coil performance. cheers: Axil On Thu, Aug 16, 2012 at 1:43 PM, James Bowery <[email protected]> wrote: > Critically, during the compression stroke the noble gasses are not in a > conductive state.
