It might be easier in China but that doesn't help Elon or Americans.

Solar powered datacenters on Earth don't make sense to me. The GPUs are so expensive you want to run them 24/7 and power cycling them stresses the components a lot so increases failure rate. Once it boots up you need to keep the datacenter powered, you can't shut it down at night. Maybe for CPU datacenters solar power can make sense sometimes, but not for AI at the moment.

Nuclear is super hard and expensive to build. It probably really is easier to put servers in space than build nuclear.
