Yes, very impressive.
The engines on our vehicle now only have a T/W of 35, even when operated at fairly high pressure. We do count the valve in the engine weight, which is fairly significant. We could double this T/W without heroic effort, but going much beyond that would be hard with a catalyst based motor.
