I cant see how it could possibly work. the leading piston moves as
expected but the trailing piston has the exact same force on it
pushing backwards. the video shows it to move forward as though there
were no resisting force on it.
the design is a load of codswallop. cant possibly function as
indicated.


Well it does seem to run on compressed air. Notice that the lead piston
moves forward faster than the trailing one. That seems to indicate some
sort of gearing mechanism around the shaft. However, his website does not
have any mention of running it on any fuels yet and when they run it on
compressed air their body language seems to indicate that they are treating
it like a quart bottle of nitroglycerin. :-)
