Which is a laughable claim because if someone truly had "free and unlimited" electricity, that would be a golden opportunity to mine Bitcoin with a very big advantage. Tell Jihan Wu you have a source to free electricity and definitely he'll be paying you a percentage of coins mined to give him access. It's guaranteed profit.
the rule is you can't use someone else's equipment you have to buy your own. can't partner up with anyone. only YOU get free unlimited electricity. not for you to share with someone else like whoever that person is you are talking about.
there are already with free electricity. some people who rent their landlord pays their electric bill. i don't see them mining bitcoin...
