Supercritical CO2 rankine turbine engine for aircraft/automobile

Interesting concept of compact and highly efficient closed Rankine cycle engine with supercritical carbon dioxide instead of water. Main application is very high altitude aircraft, but it can be also used for automotive propulsion.
Supercritical carbon dioxide is much denser than steam which is allowing very power dense turbomachinery.
Using scroll expander is advantageous for small engines, because its lower rpm.
In comparison with water based system, supercritical CO2 engine has higher radiator temperature if efficiency is the same. This greatly decreases weight and size of the powerplant which is very important for aircrafts.
