Do I understand correctly that you have worked on that project? If so, could you comment on what the people on LPP Fusion are doing? Is is feasible / safe / sustainable?
Is it safe? I see no safety problems beyond those normally found in laboratories or industrial projects that use high energy densities.
Is it feasible? Who knows? That what science experiments are designed to find out.
Is it sustainable? I assume you are asking is it affordable. I suspect that it could be supported for less cost than the toilet paper used at ITER.
