Ahh, so 6000KWh spread over a period of 17,520 hours (the number of hours in two years)
yields an average of 342 watts of processing power per hour for that two year period...
at a current cost of 8 ETH or $3080USD.

That works out to the processing power of (3) GTX1070 boards at 110w each, with combined MH/s of 90...
Coinwarz.com's calculator tells me 90MH/s yields about $1740 per year, times two years:
$3480
This investment would barely get over break even... can I buy 3 GTX's and 3  300w solar panels with controller/inverter, maybe a 200Ah battery, with that kind of money? Hell yeah. And it's “green”. I would own it forever, not two years. Solar panels have a 20 year life span.
And very useful in a natural disaster or other power outage.

None of the various DIFFERING estimates on the website/white paper instill confidence that I can get a predicable return or make a decent profit, and I'm not into “buy and pray”.

Somebody check my arithmetic:
ownership of 1000 H20 confers 6000KWh, for 24 months, and their website's calculator says that yields a
hashpower of 249.6 MH/s.
In the whitepaper, they list the power usage of the GTX1070 boards they intend to employ as
110 watt (0.11Kw), with an output of 30MH/s.
6000w divided by 110w equals roughly 54, i.e. 54 GTX1070's running 30MH/s.  So 54x30=1620MH/s
Even factoring in a worst-case 20% net profit factor, that still should be 324MH/s
What am I missing? The cost of buying 54 GTX boards?

Also, from the website FAQ:
How many MH/s does 1 Watt generate?

The current rate is 0.158 MH/watt.



6000 times 0.158 is 948MH/s...

Just wondering.
