You seem to know a bit about this: would you have a similar comparison on the capital cost issues, e.g., cost per cubic meter for the at-scale version vs. this local small scale? I mean, that's probably unimportant even if there's a big difference given that remote locations simply wouldn't be practical to have a large plant. But if the costs are even only twice as much per cubic meter, the rapidity of rollout for the small-scale solution could provide rapid relief, especially in some of the areas of the world with acute shortages that need rapid remediation even if it's only a short term solution. (like Cape Town recently)
