Thanks for your response, premium_domainer. Yes, I know how to Google and I'm also aware of the various way to compensate for the sun not shining at night. I said as much in my post (e.g., batteries, grid, diesel). My question pertains more to what envion specifically plans to do.

A big part of the appeal of envion, at least for me, is that they are trying to use green power for mining. Solar is of course one of the leading sources of green power and is the main source that exhibits the "excess capacity" that envion references in their whitepaper. But if, for example, envion intends to use diesel generators at night to keep the miners running, then their operation won't be as green as I'd hope.

The best from a green/environmental standpoint would be to use batteries that would store excess solar energy from the day to use at night. However, as I mentioned in my original post, it doesn't appear that they've factored in such batteries into their cost of operations (as a data point, Tesla's 10 kWh Powerwall costs $3,500). This additional cost wouldn't necessarily mean that they can't be profitable, but it would mean that they won't be as profitable as initially expected if they didn't account for this.

Similarly, if they use electricity from the grid at night, that would be an additional cost which they may or may not have factored in.
