Violating physical principles will tend to do that.
Nothing you described can possibly work. The "thermal heat" in room temperature (300 K) air or water is only able to do work if there is some place cooler that it can flow to.
I'm glad it figured out the laws of physics.
Yes, I'm actually trying to insist to chatgpt in many back and forth replies that it's violating the 1st and 2nd law of energy/thermodynamics but chatgpt kept its position. Eventually I asked for a walkthrough why.
At this point, the major redesign is now entirely my effort. I simply ran it through chatgpt and google gemini for scrutiny, debugging, looking for anything that can go wrong or make the concept fail.

Probably the closest clue I can give you. The engine makes its own "cold sink" (below ambient) without generating an equivalent high temperature side (above ambient) directly unlike the well known vapor-cycle refrigeration in A/C systems and the household fridge. It's none of that
.
There's more than one way to drop temperature without input of work. If you read enough mechanical engineering books/articles, you'll come across them and they're not just oddities but exploited in some industries and ironically even in power-producing industries all for the same reason - improve efficiency/reduce power consumption/reduce operational cost.
Heat always flows towards the cold and never in reverse in the engine concept. If the reverse occurs, some of the exhaust would be hotter than ambient and doing it without energy input not only violate 2nd law but also the 1st law. The engine would continuously dump energy while receiving less energy than it dumps would certainly violate the 1st law.
In terms of entropy, it's a fully reversible process in a closed system where the entropy remains constant or increasing which again does not violate 2nd law and not violating any laws of physics at all.
Mechanical engineering have already all the knowledge, expertise, technology, and hardware to design and build such engine.
Why nobody designed nor built such engine simply because it was never the goal to build an engine that ran only from the ambient heat and latent energy of humid air or water. As ridiculous as it sounds.
People just never quit thinking that obtaining heat energy always involves burning, reacting, or concentrating something to raise heat far higher than ambient. They always see ambient heat as worthless energy yet it's all around us in virtually inexhaustible quantities and the very high mass flow rates over cold exchangers achievable with existing tech, the power density can approach that of jet engines which is many orders of magnitude higher than solar power and other renewable sources of energy.
Such high power density means it can singularly power everything directly without being supplanted by fossil fuel engines (hybrid) nor using batteries (wind and solar) and not require massive land and sea area and capital (wind and solar) to generate the same power output.
It can power cars directly up to high performance. Power even the biggest airliners at same performance levels but even better with unlimited range and without the burden of fuel weight.
Most spectacularly, the engine's cold exhaust plume will condense moisture form the air and as secondary function, stationary engines can irrigate and cool hot deserts leading to reforestation while producing power all the same time. It can also provide clean, fresh water to communities.
Home units will give you both electricity and fresh, clean, cold water, as well as cooling your entire house. People living in hot climates will love this engine for sure.
It's going to be very far away, and requires a very big heat sink.
