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. David Rudiak Listen to 'Strange Days...
