IMPORTANT — read the denominator carefully. 400 MJ is the LASER CAPACITOR BANK, not total facility grid draw: it excludes cooling, controls, cryogenics and target fabrication. True facility draw is therefore HIGHER, which makes this value an UPPER BOUND on wall-plug gain. The real figure is lower than 0.0078.
