What the heck are you talking about? Piston rings are there to save money by not requiring precision honing of the bore and piston. If you select the materials correctly you have never needed piston rings.

      Just about every model airplane engine now uses a piston with no rings, and it scales perfectly well. It's just a matter of how much it costs, and the cost has been prohibitive.

      And yes, you do need to match the coefficients of expansion in some combinations of materials, and also taper the bore so that it doesn't "bell-mouth" from expanding more that the top, where it's hot, than the bottom. Either that, or allow it to be mismatched, put in even more taper, and allow heat and expansion to create the proper fit. In either case, chrome the bore, or put on a hard anodized surface to keep it from wearing out prematurely.

        People knew this all 50-60 years ago, and used it in some cases. It's not cost-effective, but it's certainly feasible.

Perhaps racist behaviour should be punished independent of any mindless "free speech" worship.

        You, sir and or madame, are the worst kind of imbecile. Because as soon as you accept the notion that speech should be censored, you put someone else in the position of deciding which speech is to be censored.

      Yes, that does mean you have to put up with all sort of racists, anti-semites, and plain old lunatics spewing anything they feel like. That's far better than ceding your rights.

Huh? If he is in his 70's, it's very likely that he never used anything like a desktop/laptop personal computer at work.

        I work in a very high technology field and we didn't have anything resembling a personal computer until the early 90's - about when this guy would have been retiring.

      The answer is blindingly obvious, get an iPad.

Even more people would sit home on their dead asses waiting for their check, while an ever-decreasing work force would have ever-increasing tax burden.

        It's already like that, to some extent. Something like 50% of the population takes government handouts already, and workforce participation is as low as it has been since records have been kept.
