"Scientist tend to forget when doing these experiments it takes energy to build stuff that goes into them and keep it in working order. A lot of them are just worried about surpassing a goal that is at this moment just getting more energy back than is put into the lasers which is an achievement but is just a first step since if is not much more than this could be totally useless for large scale sustainable energy production."That statement is grossly idiotic .. which scientist is that stupid?All cost estimates I have seen always include the cost to build the plant, the maintenance cost, and the fuel cost and amortize (basic accounting) that to estimate the cost per kilowatt. It's done with every single energy cost estimate. It's done when they estimate the per kilowatt cost of everything from solar plants (which would be way cheaper than coal if people ran around ignoring captital costs), nuclear fission plants etc.Also, do you seriously think scientists intend to stop once they slightly surpass energy payback?
