Actually heat pumps are not greater than 100% efficient as nothing can be. They get greater heat input than the power for the compressor.

Work out/Work in has more inputs. In the end there are losses.

Lot's of things are more than 100% efficient. When I step on the gas pedal with a few ounces of pressure I get 100s of horsepower! Wow! Much greater than 100% efficiency, as far as I'm concerned. That's why I have an engine instead of push pedals like in a toy car.

Try to tell the manager of your closest Mall that Heat Pumps are NOT more than 100% efficient. He knows what he spends on electricity and how much cooling or heating he gets.

If you're the manager of the Mall Of America in Minneapolis and it's 30 below outside you will turn on the heat pumps for your clients and get at least 3 times as much heat as from simple calrod heating elements. No kidding: it works! Of course the ground and air outside will get even colder as you draw residual heat from them, but who cares! That's outside.

Didn't they cover the Carnot cycle in your college physics course?

You need to draw your energy corral more properly. It is not enough to just draw it around the heat pump device.

I suppose that you believe that events of probability zero can never occur and events of probability one must occur, and yet it is quite easy to demonstrate exactly the opposite.

The shortcuts that people with meager knowledge make is astonishing.
