This is really impressive stuff

I'd be really interested to see how they have designed the sliding seals that seal at 15:1 compression a rotating block against a stationary head!!

I have no idea tbh mate but looked a very interesting and exciting project imo.

Very clever piece of engineering, I'd guess the idea came from axial piston hydraulic pumps and motors - very similar concept, it's a shame they didn't give a bit more detail for some of the problem areas but I guess that would be giving away the farm. Hope they do well with it, although looking at their website & Facewipe acc not a lot seems to have changed for a while.

Kiwi come on mate don't be like that you were clearly part of the "some"

All in jest mate, you should know by now I don't take anything much to heart

Exactly my thoughts Deegee. I used to overhaul variable displacement hydraulic pumps for Skyhawks aircraft and they had a cylinder to valve head metal to metal seal (4500 psi test press). I had to lap the mating faces to 3 helium light bands of smoothness. QA was with a 40x microscope. That's what made me wonder how they did it.

It's a great idea but a bit late for automotive as electric is the money pit for R&D. Unless these are adapted as hybrid units. But lots of scope for industrial or aeronautical use imo.

I know dude. It was clearly jest back I would never really put you in the intelligent camp.

Come on dude, surely you saw that

I put up with the likes of you, so clearly I'm a slow learner!

HAHA touché

"3 helium light bands of smoothness" ?

[Monty]

Had to look that up, 1 is 0.0000116 inches!

[Blade]

Should have just looked at my ass Monty it's the same level of smoothness

Yup I knew it was pretty extreme (22 years ago I was doing that) The lapping plate got sent away for a calibration check every year, but we just checked under a 40x microscope and when the components looked like polished granite you knew it was up to spec.
