That is it, iec320c13 to USA 3-pin plug NEMA 5-15P. I presume that 14 AWG allows me to run it on 208/220v whereas the 16 and 18 awg limit me to 120v?
Thanks again.
5-15P is 120 volt US standard plug. The 220 volt versions are the NEMA 6 series - 6-20P seems to be the most commonly used.
$7 for a standard power cable like that is also VERY high priced, unless it's 12 AWG or better - then it's just sorta high.
14 AWG limits current, not voltage - IIRC 14 is rated for 20 amps or so.
Global warming exists, but there's a LOT of question how much of it is human-caused, especially when the majority of it has been demonstrated to have happened before 1940 *AND* at least one major scientific study showed that CO2 levels LAG temperature increases by a few months, *AND* one study showed that global warming trends track the sunspot cycle length with GREAT precision (except for the couple years after Krakatoa, and a year or so after Mount Saint Helens).
Keep in mind that the world was also a much warmer place in the 900s AD, and a much colder place in the 1400/1500s (look up the year that the river going through London froze completely, and the "Little Ice Age") - this is DESPITE there being a lot more humans around burning a lot more wood in the 1400s/1500s than in the 900s....
Hint. I don't think ANY "climate model" in existance has taken variation of the output of the SUN into consideration - none of the ones I've ever seen mention of do so anyway.
I don't think any of them take cryptomining into account either, but that's still a small blip on overall human power usage.
I agree that the network probably won't drop 400 PH overnight at the halfing - but I suspect it will drop more than 140 short-term. I'd guess more like 200-250ish, as there are probably some folks that won't realise they're unprofitable for a while, a few that won't care, a few that have REALLY REALLY cheap or free electric that ARE still profitable even with S1s, etc.
How long will the drop last? Depends on how fast Bitmain can ship S9s and if anyone else is shipping 14/16nm full custom generation miners by then and how fast any of THOSE can be shipped if so. I wouldn't bet on more than a few months, and it wouldn't shock me if that pre-halfing peak rate regained within 60 days estimate proves to be accurate.
BTW - MY central heat last winter was mostly A2 Terminators, with some additional input from a few S5s, a SP20E, and my computers - I had to keep at least 2 windows open all winter at least a crack to avoid overheating my place.
