Huh. I wonder if that CO2 gets released.

  It looks like it's captive in the big bubble even in decompressed form, however I think it is always a bad idea to create more CO2 on purpose (it can be released by accident or for maintenance), which is why I really hope this startup can work hand-in-hand with direct-air-capture facilities.

    > however I think it is always a bad idea to create more CO2 on purpose If the net CO2 generated is reduced significantly, then it's a net good thing. CO2 is a byproduct of all sorts of industrial processes that we depend on, so I don't think they'll have a problem finding a supply.

      My solution (to use exclusively DAC for the CO2 supply) looks like that difficult to you? I really think it is the best way to go. It is different, in my opinion, to emit CO2 to create material goods that will last, and to create CO2 for itself that maybe will be vented for maintenance and will need to be refilled.

  No, they need to keep the CO2 gas pure, so they can pressurize it again. That's what the dome is for, storing the uncompressed gas. Presumably there is a much smaller metal pressure vessel for storing the liquid CO2.
