I’m fairly certain that this requires a Ham radio operator’s license (in the USA at least). It uses frequencies that are regulated.

It’s short for spermaceti whale.

Spermaceti is the name of the oil they produce for buoyancy/echolocation. Why is it called that? Because it was originally thought to be whale semen. Yes, really.

Alcohol also increases your blood pressure, and that has nothing to do with the liver. Still wouldn’t be a good idea to be drunk all the time.
