Speedtest.net bought a service that was doing this already sort of. I looked just now and I think it’s their “map” option on their mobile app. You need to switch between carriers to see coverage.
The tech was based off of manual speed tests and a background app that would measure coverage from a phone for a small area, about the size of 3 square acres.
US. I’d be surprised if anywhere was allowing more than 80psi.
20psi is really low so this value may have different variations. I’m on a well pump and before I replaced it I was getting down to 20psi. It barely dribbled out of the 2nd floor shower head. I now have the pump set to 60/40 with a 50psi restriction valve. This seems to be the sweet spot.
I’m not in plumbing and won’t know how to look this stuff up.
I loose-fitting but not too large shirt that does an above average job of wicking sweat away. It’s also one of my shorts that I can’t get greasy and not care about.
I don’t know any billionaires but I knew some extremely wealthy people and they def worked for it. One only slept from 1-5am, we knew because of their email and document edit times. Also had to supply them with satellite internet while they hiked up to my Everest base camp so they could keep working. Dude was intense but literally built an empire in his industry by himself.
People that were already multi-millionaires at birth? No idea.
