If you need further proof of this point, then look at the numerous perpetual
motion machine patents.

I am sure everyone agrees with Carl's observation about patents. I wish we
could forward his mail to the patent office, not expecting a major change in
the system, but as a way of paying respects to visionaries cum inventors cum
implementors like Chuck Hull. We owe them. Don't we?

PS: I have this vision of a car that flies like a jet and sails like a
ship. Of course, whoever builds it should pay royalties to me because,
you know, it is MY idea.
