Did the ENVION team determine the location of the farms? Where is the lowest tariff for electricity now?
I know that in Russia, in the Irkutsk region, electricity - one of the cheapest in the world. Also there is a very cold climate (this is Siberia), which is a very good combination for mining!
Check their most recent announcements. They have already secured some really cheap electricity from USA. They seem to be getting a lot of offers.
