In the Ozarks of Missouri.
One of my posting peeves is an "idea" that is truly only a suggestion or wish for something that everyone has thought of, that just can't be built . . . yet. Some things aren't being done because they can't be, not because the person posting is uber-creative and can leave the petty engineering to the little people.
Folding cars, helium-filled anything, different materials for common objects, all these are obvious and usually unworkable. Few of us are going to come up with new developments in highly-developed and expensively-researched fields like automobiles, bicycles, tires, dentistry, astronomy and nuclear physics. Clever twists, presented well, will get a croissant from me, but obvious unworkabilities will get hammered.
Some obvious things are simply waiting for technology to improve: Industrial Development Inevitable Over Time (IDIOT). This does not apply if the idea includes some original idea on how to improve the technology.
To me, an idea has to give at least half of the method to make something, or address at least half of the problems that a new invention will face. That's why this is the Halfbakery.
