I doubt I'll ever discuss costs, but it isn't exactly rocket science to price something similar out yourselves. Also, since this is really a prototype I have a lot of optimization to do for the next one. I'd expect I could get costs down by at least 25%.

More important that capital cost is operating cost, that's my major concern. Gensets require maintenance and must be checked regularly etc. Mining doesn't work if operating costs are like $0.10 / kWh or greater, I'd be crushed when the bear market returns.
