I think you are still missing the point in this response.

Room temperature super conductors are currently just as pie in the sky technology as a perpetual motion engine. Had I said "An electric bike powered by a perpetual motion engine" would you get the point? If E-bikes had a free source of unlimited power your grandmother still wouldn't ride one in the rain. How about a cold fusion engine for comic relief.

You are trying to argue with someone that happens to agree with you on the point things are 'good enough.' I would even include properly maintained batteries are good enough. That was integral in my post! It is tangential to topic and I would be happy to participate in the discussion as such, but DON'T invert the point of my post to get in a pissing contest. I love talking about possible future technology but haven't really done it seriously here.
