I've been very interested in this ICO and actually read through this entire thread! I'm reasonably convinced at this point that envion is not a scam (of course you can never know for sure), but am not yet convinced that it will be a good investment.
One of the things that has bothered me is how envion plans to utilize solar. Solar is great of course, offering plentiful (in certain areas) and cheap electricity, but what happens at night? Even if you can use cheap solar power during the day, the business can't afford to have miners idling for half of every day.
One solution would be to use battery packs to collect and store electricity from the solar panels for evening use. However, this would require additional and costly equipment (for reference, Tesla's 10 kWh Powerwall costs $3,500). I don't think this is factored in to either the fixed or variable costs listed in the white paper (page 60).
Can the envion rep on this forum help shed some light on this concern?
