The Vapour Compression Cycle is rather effecient, over 300% in some cases. Why couldn’t we use that to create a near limitless amount of energy by drawing heat from the atmosphere and using it to boil water to power a turbine?

Imagine you have a pump that sucks 3 gallons of gas from the ground by using 1 gallon of gas as fuel. The result is that you burn 1 gallon of gas and gain 3 gallons of gas, so you can call it 300% efficient.
However, it doesn’t mean that you created matter from nowhere. You just moved it from a useless (for you) spot to a useful (for you) spot. Obviously you can’t move more than the ground has.
In the case of the air conditioner, the 300% efficiency also does not mean that you generate energy from nowhere.
