Lynn,

I notice they use metal where necessary, this could be problematic = with the=20 rotary, especially with the end plates. I can see a way around this with = a=20 system similar to the rotor housing liner, but we are a long = way from that=20 technology. Still I would love to be around when it does happen.

I wonder why they considered the technology a failure, perhaps = longevity=20 issues.

A material similar to = carbon fiber=20 but thermally more conductive is already known.
