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....

Frequency is irrelevant here.

Oh, so if you open your faucet by another 20%, nothing extra comes out? In our(Pete & I) business, (alt. energy studies) frequency drive is Quite relevant.

P=UI*cos(fi) as far as I remember. Maybe cos(fi) for the same device (like PSU) will be a little different when powered with different frequency, but I don't expect it to be much different. 220V vs 110V gives you half of the current with the same power, and less current means thinner cables etc
