Torque acts as a force multiplier, not an energy multiplier.
Again you are missing the point.
If you have a gear that is 48" in diameter that is meshed into a gear that is 6" in diameter and the two are meshed tooth to tooth and the larger gear is turning at 10 revolutions a minute, how fast is the smaller gear turning-?

I would say 80 revolutions per minute........which doesn't matter a hill of beans. What matters is a law of physics called the law of conservation of energy.
Conservation of energy - Wikipedia
"In physics and chemistry, the
law of conservation of energy states that the total
energy of an
isolated system remains constant; it is said to be
conserved over time.
[1] This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another."
Let's say you have an electric pump to pump air to power your machine. Your machine is used to turn a generator to generate electricity. According to the law pf conservation of energy, for each watt of energy used by the air pump, the most energy you can generate on the other end would be 1 watt. And that is only if everything involved is 100% energy efficient. No machine is 100% efficient, there will always be inefficiencies due to friction.
So you can do a million different torque calculations if you like, but the energy output by a machine will never be greater than the energy input to the machine.
