I agree completely.
The science is good, and also the basic understanding, but when the engineering issues become to restrictive, we have to surround the issue (As scientists do when they find INFINITIES). As a suggestion some time ago I found that virtual hollow laser electrodes where available, but not yet developed enough to channel the immense currents. Other helps could be additional magnetic constrictors that might allow more time for fusion to take place before the decay of the plasmoid. Nature does it all the time, some help from astrophysicists could spark the idea
