I've had invention ideas over the years, as an artist they seem to come naturally. I have this one now though, that I think could really do humanity some good and help me support my family. It involves recycling. I think I might be able to even fabricate some type of prototype but I don't know if it would be good enough to resemble the final product? I also don't know if it would be nessecary to patent the idea first? And how cost prohibitive that would be? Help!
