1.3 Megajoules (MJ) = 1.23216 Cubic Feet of Natural Gas (cu ft ng) = 1,037 Btu per cubic foot = $1.00 residetial delivery. A pilot light for a week out of grain of rice sized target. Very neat.
Need GJ from MJ amounts of absorbed power by the fuel. A x100 - x1000 is interesting. Perhaps x 50 would be interesting in continues operations.
But I must say this is large enough scale to put flux numbers together with detectors a few yards away and move this to something other than a supermassive facility.
They need 50 years of development at the rate of Integrated Circuits for MR. Fusion. That would be cool to see, and liberals would hate it.
