You are just quibbling.

Beggin your pardon but that's what this thread
is about.

The fact is, energy (or the power, if you like, the time values are the
same on both sides, so it doesn't matter) goes into a regulator and comes
out. What comes out is less than what goes in. The difference is wasted,
ultimately as heat.

No disagreement there, I was taking exception
to your use of certain terms, incorrectly.

You comment above about how gas regulators behave is
true for *all* devices that transform energy from
one form to another - whatever energy goes in, comes
out somewhere else, less some heat.

There's only one kind of machine that's exactly
100% efficient.
