Huh, the Canadian province of Labrador has about those electricity prices. For big customers they go down to almost $0.02/kwh on the nose.
I heard kuwait has power that is $0.01/kwh. And venezuela goes down to $0.0063/kwh (if you use the actual exchange rate). I've got a feeling the latter two countries might be difficult to set up datacenters in, though. Heh.
3 cents a kwatt and a downvolt of an s-3 to .65 watts per gh vs .79 watts a gh and 1ph of them make serious money.
1th would make a 2.37 usd profit a day
1ph would make a 2370 usd profit a day
so with a 1ph would be 2400 s-3's at 50 bucks each maybe at 40 bucks each. so 100 to 120k for 1ph
now in s-5's cost would be say 300 each factory direct for 900 cost 270k
so I am thinking they wrote a software for easy volt and clock of s-3's .
the savings on s-3's over s-5's or sp20e's per ph of hash is huge. they have an interest in getting as many s-3s as they can get. A guy like me at 10 cents winter or 16 cents summer an s-3 is worth zip.
This is why growth is still slow but if some comes out really good like .2watts we may see more growth.
