Question about UT power generators

If your ultratech generator is running at 50% efficiency, it's broken.

This sounds good for people comparing it to internal combustion or gas turbines, but a modern steam plant can reasonably hope to do that well, and a fuel cell installation should do better. If you are running a fusion unit, with a hot side temperature of a billion kelvins at 50% thermodynamic efficiency, you might want to add a topping cycle on your half billion kelvin radiator...
