I am expecting this tech to be advanced very rapidly. It starts by been stronger that diamond.
The Carbon-Carbon bond is 12 eV. Let us assume for the sake of argument that the Graphene bond is 10X that - 120 eV.
The pulesd energy involved is at minimum 10KV at mega Amps. There will be serious electrode erosion. Even if the electrode can be reformed quickly there will be the problems of contamination of the insulators and the reactor vessel.
Note that carbon nanotubes are a practical room temp superconductor. Not a superconductor on the lines of zero resistance, but in terms of many times more amp capacity than copper, silver, or gold (superconductors tend to have rather inflexible catastrophic current limits). It can exhibit metallic or semiconductor behavior depending on the number of rings around the loop. Given the thermal tolerance as well, IMHO they should be making their plans for magnets out of nantube wire.
I'm not up to date on the conductivity of CNTs. Do you have some links?
