They put batteries for night.
The thing is that they need 50k investment for solars panel, batteries and one miner s21.
They say they will refund the full amount of money after 1 year due to irs.
their ask is different then when I looked into them.
But here is an idea
go to altaitech.io
https://altairtech.io/product/bitmain-antminer-s21-xp/buy 4 of the s21 xp units.
contact my host
https://iowamining.io/https://www.youtube.com/@IowaMininghave altairtech ship the 4 units to nate at Iowa mining
instead of 50k out of pocket it is only about 30k
you mine with 4x277=1108 th
with Tesla you mine with 200th
power cost more at Iowa but startup costs are 20k lower.
and you have 1108th vs 200th
