heard about erthquake in china Sichuan area .
Do you know where hashnest mining farm is located ?
Beijing, according to Hashnest FB page...
Not sure how Beijing is realistic.... The capital city is in the process of migrating dirty power plants elsewhere to help combat environmental issues. Power comes directly from the grid would cost around $0.1/kwh. All existing mining operations source from off-grid power, which i doubt any would exist in Beijing or nearby.
It's interesting, I'm sure I read somewhere that it was Hong Kong. Not sure that's any more likely. It's probably somewhere where there's either lots of space (for solar cells) or a poorer area which remains with a good connection to the grid (as it's quite high capacity).
I'm not sure how much coal is there, but it's possible they could produce their own electricity fairly cheaply.
