actually O'rama, we (Americans) have both 110 & 220 installed in most households. Just the 220 is usually used for large appliances, like ovens & driers, also come with a plug end(pigtail) the size of a small fist....lol
I never knew. That said though our (EU) voltage (especially Germany) is a lot more flexible, you can step a lot higher, but I doubt people will want to turn their houses into datacentres in the long run. If you do you could prob host other peoples kit, which would be a business in itself...
I could be mistaken, but I'm thinking 60hz could step higher than 50?
But of course we have 3 phase vs. ? Not that this matters any....
My dad is an electrician, so I grew up around this stuff. 50 Hz doesn't make a lot of difference as far as stepping up or down, but it is safer to handle , as your heart also runs at about 60Hz. Still a bad idea to make yourself part of the circuit
At any rate, there is just as much flexibility in the USA as in EU, just depends on how you want to install it. In a house or shop that you own, you can get pretty much any power configuration you desire if you have the resources to have it properly installed. In a rental you're pretty well stuck with 220/110. And, unfortunately, most residences have a 200 amp service, so you can't expand a hell of a lot without getting your panel and meter replaced (or a second setup installed).
What I"ve seen being a bigger issue is the incredible variance in generated power in the US. In most of the western states it's pretty clean, and tends to run 3-5 volts RMS above rated. In some of the midwest and the eastern states, I have put a meter on the wall and over a period of an hour seen a +/- variance of up to 30 percent. That will let the smoke out of your electronics. It is well worth the money to get a UPS and very good line spike protection when dealing with potentially sensitive electronics. Line power hasn't gotten any better, but electronics have gotten tougher over the last decade. ASIC mining manchines are likely NOT up to consumer grade standards. Don't let a utility company kill your investment.
