Good analogy on engineering grad school lol. Just to throw in my two cents, I earned a BS and MS in structural engineering at a top school and agree that ChemE or CE/EE were generally regarded as the toughest.

Can you design a way to run a bank of HPS or MH 1000W lamps in your basement 12 hours/day without noticeable spikes in power consumption and without creating an IR heat signature, or design a substitute that provides equivalent lumens output while accomplishing the aforementioned design goals?

Might be a profitable engineering exercise.

Did you take a course in undergrad called Fields, Matter, Waves? If so, how did you stay awake enough to pass the class?

I stopped being an EE major then.

It's impossible to not create an "IR heat signature." An "IR heat signature" means there is an unusual amount of heat coming from the area. If you're powering anything, there is going to be waste in the form of heat. The only thing you can do is mask and vent it.

To avoid spikes in power consumption, run your own generator or steal the electricity.

So generator + some type of shielding installed in the ceiling then?

Are electrons always spinning? If they are spinning what's powering them?

I asked this in SMP (and had no luck):

Would it be possible to create a simple thermometer using a circuit with a bi-color LED, some type of thermistor, and a battery, the output of the thermometer being either of the two colors (i.e. above or below a specific temperature)? I've done some research and found that thermistors, carbon resistors, and thermocouples can all be used to measure temperature - which is the simplest/best to use for this purpose?

I'm a sophomore chem eng major, this is for part of a project for an introductory engineering class ("design an original product or improve upon an existing product to improve everyday life").

You would need shielding all around the heat source, not just the ceiling. Also, shielding by itself won't work. The heat still has to go somewhere. I'm not an expert, but the best thing I can immediately think of are cooled walls surrounding the grow room and venting the heat out somewhere undetectable. That'll be tough though. I'd suggest venting it out in multiple pipes into multiple places. Sources of water are best. Maybe the sewers or a nearby river?

If you want to hide the heat, its easier to hide it as something else that is explainable rather than attempting to remove the heat entirely.

I've only had a basic circuits + computer engineering class, but this seems trivial to do with a thermistor.

You'd probably need a few more trivial components to do this. At least some resistors.

Thermistors and thermocouples are fairly similar in terms of what you get as a result, but you will have different ranges and accuracy levels with them. Thermocouples are pretty much the lowest end of what you wanted, but would work for a lot of situations very cheaply with reasonable accuracy.

it would be much simpler if the LED was just on off instead of bi color.

Just move to California or Colorado and get a license to grow medical marijuana.
