There seems to be a never ending slew of them with their 'inventions' - i.e. poorly labeled drawings with nothing more than a "I guess it will work" to back it up. To be honest, I am getting sick-and-tired of these never ending bad ideas littered all over the engineering forums. Just like the independent research, I ask there be strict guidelines for these nonsense threads. If you have an invention: -a: have very detailed drawings with clear labels and 3-view -b: have some background as to why you invented it, and what current ideas are to solve the problem -c: what kind of a patent search did you do? -d: what engineering analysis have you done so far? This is very basic stuff any undergraduate engineer should know. These threads are appallingly bad. Don't post your half brained inventions here and call it engineering - its a joke. Edit: Also, stop asking for magic software that will design a space shuttle for you. No such software exists.
