I think this one will not be able to even stand next to MW power DS4G Thrusters.
We can around 2 kW/kg propulsion now.
130 W/kg seems somewhat of an underachiever, not really solving the problem of
"power-starved" payloads.

I think this proposal is going to be dominated by the heat sink
problems. I know of one way to solve such problems, but it can't be
tested on earth. If anyone wants me to go into details, please ask.
