It just came to me in a flash of brilliance, or perhaps my fingerless gloves just caught on fire while I was heating a spoon with a zippo:
Gravy.
Hey man, I appreciate your input and shit, but
gravy? I mean I aint running no soup kitchen for the homeless with my mining operation.
Foodstuffs are generally out when it comes to organic fluid cooling, jam and shit is just nasty and doesn't work. Ethanol and benzine should work better apart from the fire and biohazard.
You are obviously no gravy expert.
The gravy in the closed loop stays hot, so it will not spoil. You could even have a tap plumbed into the loop so you could access warm gravy with the turn of a stopcock. The one issue you may run into is thickening, but you only need to add water, and it'll all be good.
Look man, no disrespect, but you're clearly out of your depth up in this intellectual thread about cooling systems and shit. Choosing the correct coolant fluid is a scientific process and you gots to know the detailed properties of the shit you use.
Scientifically speaking gravy is just water and bits of mashed-up animal junk. So I don't know what you think is so special about it other than being able to feed the homeless warm coolant gravy. Jesus man, this forum used to be high-brow with lots of intellectual-assed motherfuckers posting dope technological ideas, things sure are going downhill!
Also, I like the idea of a aquarium pump some other poster proposed. Gotta watch them fumes though, or get a gas mask.
