The problem with a flying machine may not be the physics, but the engineering.
Specifically, power to weight ratio. Until the invention of the internal combustion engine, people tried to power planes with steam engines. And in that context, Edison was right (he was, after all, a steam power expert). Regardless...
That about clinches it for me. You guys can discuss any non-sail driven flying machine to your heart's content, since the notion doesn't break any known laws of physics, but please do it in the theory development forum.
...none of that affects my point in any way. Actually, since its an engineering problem, discussion would belong in the engineering forum, not in the general physics forums. Study of the nuances of the aerodynamics (some of which had been figured out, some of which had not), could go either in the engineering or physics forums.
Nice to have you back though.

if this forum was the 16th century then where would fit galileo and giordano bruno?
Well, Galileo would probably go in the general physics forum unless we opened up a "Galilean Physics forum", seeing as how he kinda invented what we now call "classical physics".
Once again, where you (and zooby) have it wrong is that the newness of the idea isn't what makes something pseudoscience, its the
method of investigation. Heck, you would have liked the 1600s (and PF wouldn't have done well) - since science was in its infancy, very few people did any of it. But it was a booming time for all sorts of crackpots - alchemy was big back then. I hear bloodletting was a hot topic...

Ivan put it quite well:
I won't protect anyone from the wrath of reason, but I do allow fringe discussions and theories to be posted; esp where good science and logic is applied.[emphasis added]
