Ah yes companies that famously refine oil only to pour it into a hole and light it on fire for their own amusement, one else uses it at all.
If it's just these companies that would be affected let's just close them down. I'm sure it would make no difference whatsoever.

I just don't see this taking off. The solution is werid.
Factory build houses seem way more likely but they also have big issues. Namely cost being a barrier to entry and scale. Hopefully china or India or even china in Africa sort it on a mass scale and the economics get proven.
