Let's suppose the crankshaft bearings ride on MRC 206S hybrid bearings. Rated speed is 12000 rpm with grease and 15600 rpm with oil lubrication. If water had the lubricating properties of oil at a much lower viscosity, the rated speed would be even higher.
But,
1) Water doesn't have the lubricating properties of oil. 2) Even if it did, the extra speed capability would never be used so this is no benefit. 3) If water lubricated hybrid bearings could be made to work in a Cyclone engine, Cyclone would have demonstrated that in the last decade. Not to mention the fact that the engineers at Ohio State University would not have recommended a bearing research program as the next step in making the engines work if they believed water lubricated hybrid bearings would give acceptable life.
And then we have this classic from Frankie on Facebook:
That's the technical acumen of folks running Cyclone. Somebody slipped in the bathtub and concluded every engine manufacturer on Earth, ever, has got it wrong by lubricating engines with oil.
And Cyclone has still never publicly demonstrated an engine powering anything. Ever wonder why?
