I'd sure like to see bit more detail on how intake and exhaust are managed= =20 and even the slightest hint how lubrication and cooling will be achieved. = I=20 saw the ported pistons for cooling, but with that portion of the piston=20 inside the cylinder wall I don't visualize the path of the cooling air flow= s. Except for things like any pumps and valve trains not shown... it looks li= ke=20 this engine design might just run in reverse as easily as forward. Website suggests a running demo by summer. I assume this summer... so mayb= e=20 just any day now.
