Spaceships 2-8 new drives

A TL 8 superconductiong one requires extra radiators and provides .1G per system, and costs as much as a Standard drive. TL 9 and up superconducting drives do not require significant additional radiators and provide .2G per system.

Presuming the hype is correct, of course.

Note that for the hype to be true the drive not only has to diss Newton (equal but opposite reaction) but Einstein as well (E=MC2).

An EM Drive that didn't cause a ship to gain more KE from acceleration than electricity put into it could explain would have very low performance.
