I heard there was a programming language where you programmed a tree, that you could only manipulate manipulate in a “IDE” that looked a bit like Microsoft Word and saved the “source code” as a binary file.

According to my cursory research, cooling loops run somewhere between 10 and 50 °C with the difference of inlet and outlet between 5 and 10 K.
Steam power generation uses the phase change of water, so you need above 100°C.
On the high end of the temperature range, you could possibly run some small district heating while the lower temperatures require active cooling.
