That's actually an interesting situation, but it doesn't support the assertion that the power would "otherwise go to waste" or that this is something a lot of bitcoin miners do. The argument that it's non-trivial to just transmit the power elsewhere is a persuasive one, the argument that bitcoin mining is somehow uniquely able to take advantage of that power is not as persuasive. Even if the argument is that compute heavy data centers are the only use-case that makes sense, there's lots of compute use cases other than bitcoin. And obviously the former presence of the aluminum shelter suggests data centers are not the only good use-cases. I understand the appeal of the argument that bitcoin mining has less energy impact than people think because it can uniquely take advantage of weird edge cases, but it doesn't make sense to me.
