You silly Americans, with your 120v outlets. Take a quick look around your house, and you will find many electronics rated for 100-240v input. This includes almost all PSU's, although they may have that red slider switch, if they are really old.
Just put all your gear in the laundry room, toss out the electric dryer, and there you will find a 30A 240V outlet, which at a safe 80% load, gives you 5760 watts, with a 7200 watt peak load.
Or put everything in the kitchen, and toss out the electric range/stove. There you will find a 50A 240V outlet, which at a safe 80% load, gives you 9600 watts, with 12000 watt peak load.
Or if you are REALLY into it, say, you want to mine or something, spend $300 and have a 30/50A outlet installed in the garage. You get to put all that mess into one area, and only that one area has cooling issues/costs.

I visited CureCoin, and just quickly browsing around, I saw that I was able to join, for 1%, one of these sub-teams. I did not see what the advantage was, to being on a sub-team, but no, I don't think these are individuals. Perhaps EOC could be petitioned to exclude gridcoin sub-teams?
