  while it is obviously a sarcasm, it suggests that there is need to point obvious difference between energy and power and its density. Inertial confinement schemas don't require large energy, they require huge power and power density though. I.e. a few joules in a femtosecond impulse concentrated in a few cubic millimeters volume. Reaching that power and density is just a pure engineering task, there is no hard physical limits preventing it as there are for example on the minimal size of tokamak.
