Life changing events

Ceramic has no friction when rubbed togeather, does not expand when heated, and can do unbelievable temps without changing it's properties. You could do a motor with no rings (tollerances of 1-2 microns), no oil, and let it run as hot as the fuel burns.

You are correct about the ceramic - but remember - there is a good reason ceramic is not widely used in automotive engines. Long term reliability is a significant factor with ceramic. Also, impregnation from oils and fuels can cause degredation over time - especially when combined with heat. And at 60K rpms, there WILL be significant heat.

You didnt perhaps work in the aerospace industry in Seattle for a time did you, Mr Smith? I used to work with a guy by your same name.

Good luck with this development. Regarding the patent, remember, the smallest details can make a huge difference in a patent.

Also, for prototyping, there are companies that offer rapid prototyping. The materials are usually a starch based plastic, some similar to epoxy resins (these are a bit more pricey). Not sure if that will apply to you, but it may be one option. I'd guess a complete shock would run you about 50 bucks to have made, 100 or so if you want to fabricat one that is slightly funtional. I am flying to Orlando in a month to the Rapid Prototyping National Conference - should be interesting.
