Why don't we use thermocouplings for energy production?

A thermopile costs next to nothing to produce. It's pieces of wires welded together and can produce energy from any temperature difference. A heated home in Alaska with some thermopile blocks could probably power everything in the house besides the heater and stove. Same could be said for recovering energy from an A/C cooled home in Florida.

More practically, why are high-temp coolant lines and engine blocks not entirely lined with thermopiles to generate electricity from the waste heat? For that matter, steam turbines in power plants on the main... It's basically free energy, right?

How will I know that I can handle it? Does anyone have a "must-know" or "must-have" check list to whether or not you will make it out of first semester/year?

I start this January and It's all I can think about right now.

From what I've heard, it's so similar to ME that engineers in the field advise to stay with ME.

he grew his hair back so chromedomes have to actually try to shill that he's a loser, with his billions of dollars and great projects that nobody else has had the balls+money to do.

it's pretty ridiculous to take anyone that shits on elon musk seriously.

What do you think of radioisotope thermoelectric generators(RTG)?

What would someone major in if they wanted to work on/with these?
