Well I guess when you put it that way, the answer seems quite obvious.

What are some other engine types and peak efficiencies? Very curious to see the efficiency of rocket motors.

Edit: As an interesting aside, the muscle "motor" is only 20% efficient. Funny, food conversion is the one energy source most people wish they weren't so efficient at processing.
