If you overlook the losses, doesn't the relationship still hold?
If the force relationship is [F1/F2]^2,
If impulse F1 is 1/10th the force of F2, F2 will react as if F1 was a
mechanical force of 1/100th.
If impulse F1 was 10x the force of F2, F2 will react as if F1 was a mechanical
force of 1000x.
So, if he is correct, a large ratio difference (in favor of impulse F1) would
supply a huge amount of power. We could happily accept the losses.
Is the impulse force ratio correct? (or has he made poor assumptions?)

Not that I'm saying he's right.
