doug,
actually, this site is pretty supportive about "out of boxing". i watched a hydrogen cracker get shattered on a motorcycle site, not because his idea was good or bad, mostly, because he was a jerk. there may, or may not be valid science to support (or deny) the crackers, personally, i dont really care, i think the concept is cool, and experiments are great.
a few of my own experiments have failed, but i did make a really cool tool that tripped electrical circuit breakers when i was a kid. the home made parachute was kinda a fail. and a few of my motorized creations probably should have had less motor and more breaks (brakes it's a wash).........
this site has supported some crazy bobbers, some psychotic repowers, some fairly nutso 109 conversions. every kind of fuel being shoved down the injectors of a multifuel, some lift kits of cucvs that were "over the top". i think that it really has come down to the "tone" of the poster. and face it, if you say you made your duece go over 65 other than out of the back of a c130, you better have video
