Quote above:
"The education is sorely needed!"
Agreed. A large part of the equation for successful education in the Trade Schools is funding from the Federal Dept. of Education, a department that in the past week reduced or dissolved education funding to all states; for all I know the department exists in name only.
I don't envy the challenges ahead for the OP and best if students get involved asap, but lack of funding may doom the industry
Responses from instructors in the trades welcome on the demise of funding from the Dept. of Education and its anticipated effects

I guess the people that buy them for fuel storage use are wrong and all wet in thier thinking then.

Re: Wrestit wrench
It's just not true that China only makes junk. I remember when people used to say exactly the same thing about Japanese cars, steel, guitars, and motorcycles in the 70s.
But nobody would say the Japanese make junk today, their products are highly thought of, even those same ones from the 70s that people called junk.
China makes stuff EXACTLY to the specification of the American and other international companies that contract with them. They make the finest computers, the finest smartphones, the best drones and so many electronic components. They right now are making an electric car that is so good the US had to make it illegal for fear of the competition.
When China makes junk it is because some American company asked them to. OK some of their junk is of their own doing, but you get my point I hope.

The Highland petrohopper is a steel tank within a tank. The Petrometer is tank monitoring system that provides the user with actual tank level gallon readings to avoid guess work about how much oil there is in the tank.

For the money and work involved a Highland 275 or 550 gallon Petro-hopper would be a better option as it is designed as a steel tank within a tank with a top draw.

Re: A2W efficiency and calculating BTUh per SqFt....
That "Heat Energy" from the refrigerator is less then 1:1. The cool air has already left the refrigerator and been replaced by the air you have paid to warm up. The only heat you get is running the compressor motor and thats 30 - 75% efficent depending on the model.

Re: When to NOT use sharkbite? A question
I believe you are correct on this 90% of the time.
But, picture 1/2" copper in the floor that moves over to a vertical wall (which you must transition to). Just slightly in front of the wall (toward you) is floor joist. Someone previously opened the top of the floor joist by about 1.5 inches so you can get to the far side of the floor joist (where you need the elbow).
I challenge you to get a torch through a 1.5" space in the top of the floor joist to the far side and sweat the horizontal of a 1/2" tee that you certainly can only get to one single point with the torch and pray that the solder goes 360 degrees all around the tee. THEN, if you are successful, you need to lower the 1/2" copper down the wall…………..engage the tee (which you really cannot see)…………and sweat it again. Of course, since you are below a floor and next to the floor joist, you'd risk catching fire to the building whereby only a bucket of water might extinguish (because it is behind the floor joist and you cannot get much water through a 1.5" space)………AND……….. disintegrate the first floor ceiling if you manage it.
Still think you can sweat that safely?
Sharkbite.
Done.

Re: When to NOT use sharkbite? A question
Sharkbite is the easiest type of connect to disconnect, the only thing that comes close is threaded brass. So I like them for places that are likely to be disconnected.
Sillcocks fail all the time. If you get one with a copper sweat or PEX-B connection the pipe tail will be smaller than the body of the valve and will easily go into any hole that the valve fits in. If you put a Sharkbite as the first fitting on the inside of the wall it becomes a five minute job to switch it out.
The kicker is that almost certainly the replacement sillcock is going to have slightly different dimensions than the one that was in there. With a Sharkbite all you have to do is adjust the length of the tail piece of PEX or copper. You can even cut it long, attach it, measure on the outside how much too long it is, then disconnect it and trim to length. Easy-peasy.
If the inside of the sillcock is exposed I like to have a Sharkbite quarter turn shutoff valve as the first fitting inside the wall.
Re: Simple effective addition of AC to dome home?
A minisplit AC cooler/ heater will require you to drill a hole through your concrete dome? I have an alternative. Consider installing a Heat Pump Electric hot water tank instead. ( disable the resistive heating element) Use the cold coils and a fan to cool and dehumidify your indoor air. Use the hot water however you want to. If you want more cold just dump the hot water outside of the house ( into an outdoor hottup or pool perhaps. Dehumidifying your indoor air by itself might solve your indoor comfort problem. Most people like 70s F temperature? Have you measured the humidity?
