What about rocket engines that have no rotating parts? What about when you blow up a balloon and release it? What propelles it across the room?

A given force at a given velocity.

Multiply them together and guess what you get - power! That's why I stated power is universal.

Doesn't matter where the force comes from: a blast of air, jet nozzle, propeller, or torque (which is simply force in angular domain), it generates power at a given velocity. That power is what puts objects in motion and gives them acceleration.

Torque is a mean of producing power, as is the fossil fuel. Saying torque is which get you up the hill is as ridiculous as saying is the dead dinosaur that gets you up the hill. Both correct, just ridiculous in terms of physics and engineering.

The question wasn't for you. I am agreeing with you. Mostly.

I'm surprised the relationship between HP and torque is so difficult to grasp and are often treated as one or the other when for the purpose we are speaking of, they are interdependent. You can't make power without torque but unless you make power, torque gets you nowhere. Power is the measure of how far and fast torque can get you somewhere.

Going back to the old weight lifter analogy. Torque is how much you are lifting. Power is the number of reps you can do in a given time with that weight.
