If you were to tell us your idea, we would be better able to help you. There might be something that you might not be thinking of that we think might work, for instance.
I don't care if you want to tell us or not, but we're only able to do so much if you don't. Think if it like you coming on the forum saying you need tubing for water :hammerhea Weeeeeellll... what kind of tubing? What diameter? How many gallons per hour must it sustain? Any special pressure ratings needed? What's its intended purpose? Catch my drift?
