Even at 40% efficiency, the amount of waste heat (60% of 125 KW) would be enough to vaporize a 30 lb tabletop device in short order, unless there's some really efficient way of removing that heat.
It's also illogical to throw away 60% of your output, when you could e.g. put a water jacket around it, convert the water to steam, and use that to drive a turbine & generator. But that's boringly uncool, so I suppose it doesn't attract
suckers investors :-)
