• "An average of 420 joules of ultraviolet laser energy, known as 3-omega, was achieved for each beamline, for a total energy of more than 80 kilojoules (a joule is the energy needed to lift a small apple one meter against the Earth's gravity)."
• "A joule is a watt-second, so this capacitor could deliver one watt for 0.4165 seconds, or 0.4165 watts for one second, or any other combination in which watts times seconds equals 0.4165."
• "Ok then lets say it has to deliver above 2000 joule of energy on target at 100 yards and has to have a premium bullet .. 30 carbine out 30-30 in 223 out 22-250 in barely etc.. a 22-250 will do the job with barnes-x and a good shot .."
