That’s a hell of a lot better than most other systems. If true, and if scalable, this is a huge innovation.
compressors, turbines (like steam turbines), piping, some of which heat-resistant (500C), container for liquid carbon dioxide, lots of plastic for the bubble, something for thermal storage, dry and clean carbon dioxide, these aren't unusual or restricted resources, don't depend on critical raw materials or anything like that
