Has a bit of journalistic hype in it.  It says it will produce
200 petawatts (200 x 10^15 watts or joules/sec) or 100,000 times
the combined energy of the world when it fires (per second), but
the power output is only for less than a trillioneth (<10^-12 )
of a second.   The total energy in the beam per pulse (power x
time) is only around 200,000 joules (200x10^15 joules/sec x 10^-
12 sec), about what 200 homes running at a typical 1 kilowatt
each would consume in a second, or one home's consumption in 3+
minutes, or ~5% of the total energy stored in your car's lead-
acid battery.

The hyped writing makes it sound like a stupendous amount of
energy, but it is really only a moderate amount of total energy
concentrated into a very tiny time and space to produce a high
power rate and density. Despite the hype, sounds like an
interesting science experiment that could produce some very
interesting insights into the physical nature of the vacuum.
