How about this explanation, for the engineers in the audience.

Power is Torque x speed, in a rotational sense as you have in an engine. Thus (Torque NM x RPM)/9550 = kW.

Thrust is the force generated by a fan, prop or exhaust gas expulsion (rockets). So the thrust from a Prop or Fan is the reactive force which is generated by the power ((nmxrpm)/9550)of the rotating fan/prop blades.

So in order for you to have excess thrust, to accelerate S&L or to climb, you need to have excess power. (which I have stated there is no such thing )
