Just throw a Mazda RX8 motor in your ski. Vroom Vroom
Better yet, supercharge it!

So all the sealing is done using sliding seals
Sounds like the challenges the Mazda rotary engines had with their non-lubricated rotor seals.
Looks like those seals need to seal while the valve continues to rotate, right through the entire combustion cycle. Heat, pressure, and fast sliding motion, with zero lubrication...
Some of the other claims seem dubious, like why wouldn't you still need water jacket for the cylinder head? It is still the top of the cylinder chambers, and still gets hot. Still has exhaust gases flowing through it...One engine has gone 150K, but how many times has that head been torn apart and re-worked?
The pollution chart was odd - 13 road horsepower, it was measured with catalytic converters, and it shows the BEST numbers taken from multiple runs. Not typical numbers, the best numbers...
I am sure these things can run, but real-world longevity would seem to be the question.
