That’s thermodynamically impossible.

Not true.

For example you could convert the heat into photons (infrared radiation) and beam that out of the room without needing a pipe. You would probably need an infrared transparent patch on the window to aim at.

Why? You could theoretically take out energy from the room in the form of electricity
You can’t. The second law of thermodynamics prohibits it.

“It is impossible to devise a cyclically operating device, the sole effect of which is to absorb energy in the form of heat from a single thermal reservoir and to deliver an equivalent amount of work.”

How does having a hot side of a piece of material and a cold side of a piece of material come under "cyclically operating"?
Perhaps not an equivalent amount of work, but if we could capture some of the waste....
