thankfully we will have a competing frontier model from the next lab shortly I'm sure and I hope they are reading this feedback and swing theirs the other direction.
My medication is billed as "thousands per month" but the insurance company pays a different rate than the 'billing' rate and all I pay is $20/month for my biologic infusions. If I didn't have insurance I could enroll in the drug program and get it nearly free. I think its really very rare for the case you mention.
AFAIK, Electron holes refer to the P-type charge carrier in a semiconductor lattice where the absence of electrons behave similar to electrons in an N-type semiconductor. Benjamin Franklin was not concerned with solid state physics rather he's referring to the charge carrier in a conductor being positive when we later discover that its negative (electrons). When current flows through a conductor its just electrons (not holes) moving from negative to positive.
It’s true US isn’t competitive but what you looked at was hobbyist PCB services which is not representative of the industry as a whole. I get the frustration but i don’t see how you can draw any conclusion from it.
True, skin effect limits the conductor size (~22mm in Al @60Hz) but overhead transmission already uses bundled conductors to address that as well as to improve mechanical strength, cooling, and reactance. The advantage of HVDC is in the lower dielectric and reactive losses while skin effect is minimal.
Power line losses are proportional to I^2R so whether its DC or AC isn't really the concern. V=IR so assuming R is constant, a higher transmission voltage results in exponentially lower power losses. DC is actually whats currently used for long distances to achieve lowest power line losses (HVDC).
