    The issue is always energy density and round-trip efficiency, and I don’t see numbers for either of these. Remember that you do have to actually liquify the air first, and that takes power.

      Yes, no-one is claiming this car runs on free energy. The advantages are a light-weight mobile energy source and zero-emissions. The expansion ratio IIFC is like 80% that of gasoline, which isn’t terrible. Condensing air is a process that is energy intensive, but does not require non-renewable energy to perform.
