I read somewhere that "authorities" in the region were positively
denying the possibility of manned flight for at least 5 years after the
Wright Brothers were demonstrating the airplane. What's that old saying?
When someone comes up with a revolutionary idea,
First they're mocked,
Then, it could be true,
Then, it's accepted, (sometimes after the originator's death)
Then, others say they discovered it first.
(To whom it may concern. My email address has changed. Replying to former
messages prior to 03/31/12 with my personal address will go to the wrong
address. Please send all personal correspondence to the new address.)
(PS - If you email me and don't get a quick response, don't be concerned.
I get about 300 emails per day from alternate energy mailing lists and
such. I don't always see new messages very quickly. If you need a
reply and have not heard from me in 1 - 2 weeks, send your message again.)
