There are so many new ideas for engines to replace the good ole piston engine, but almost none of them ever make it into production.  The ancient piston rules.  Here is another one of those new engine ideas which seem to have several significant advantages over piston engines (No one usually lists the disadvantages).  This one can be compression ignition, 2 to 4 times the power to weight, multifuel including JP8, more efficient, far less vibration, less complex, and can be self supercharged.  You are going to like this one.
