Yep, 100% efficiency would be quite a benefit.

There are audio amplifiers with output impedance around .1 ohm, driving
8 ohm speakers, and having efficiency nowhere near 80/81. The theoretical
limit for efficiency of a class B amp driving a resistive load with a
sinewave is 78.54%.

Of course, that was a tongue-in-cheek posting.
But if you could design a Thevenin equivalent
source with a 0.1 ohm source impedance, wouldn't
the efficiency calculate out to be pretty high?
