Interesting idea, very noisy. Would have liked to have seen/heard the demo engine running.

Certainly is interesting technology, one that I would like to see perfected and put into mass production. I wouldn't be too concerned about noise too much petey, I have no doubt that can be overcome, take today's diesel engines compared to a diesel engine from 10-15 years ago, back then they were truck engines stuck into 4 wheel drives, now the NVH levels are low enough to stick in an everyday shopping cart.

Interesting. F1 has used pneumatic valves for a really long time which do away with valve springs in place of pressurized chambers but they still use cams as far as i know. It makes sense to have a system that is essentially infinitely variable so I assume it was either banned in F1 or technical issues stopped it from happening.
