  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, 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

  Compressed air without heat recovery is more like 30%, so this is huge

  I was just about to bang out that they must lose a lot of heat from the compression. But apparently not! That’s amazing.
