I have no idea what you're suggesting, but they could apply the atmospheric heat once, after that they'd need to find ways to cool it down. But perhaps you could build a perpetual motion machine – you extract energy from the initial heating and use it to cool the water down after that.

What's a pressure vessel and what does it do?
