That is Apple's solar farm powered data center facility. They have one, so why can't Bitcoin?
Probably because incompetent management killed the only project silly enough to pursue it at the moment
Even in the op, the closest you could have come was buying a small building and getting solar covering the roof
You potentially would have been able to run a rack or two for mining, then rent space.
If a data centre comparable to apples was what you had in mind, Usagi is right, you are delusional.
