The big criticism of the bong coolers has been that you have to add water to them almost on a daily basis. This guy is trying to solve that situation with a more closed system. So, he tries out an idea on the group. It seems obvious that he's put a lot of thought and effort into his idea. Personally, I say let him try it. He may or may not be successful, but he'll have the challenge and the possibility of solving this problem. Too, someone may learn something from his experience that gives them an idea. That is a free "academic" type forum. Criticism, even if it is constructively intended, may inhibit others from trotting out their own ideas. On the other hand, pointing out the obvious flaws in an idea may save someone the "trouble" and expense of a project that doesn't work. There are certainly two sides to this view.
Corportal Hicks - I really do believe that you mean your criticism to be constructive. But sometimes it might be better to encourge novice talent - especially since there is probably little expense involved in the guy's idea.
I'd suggest this. Go back and reread your posts: count the positive comments versus the "Constructive Criticism". How's the ratio?
Incidentally, this is honestly intended as constructive criticism. How constructive does it feel? Now - consider receiving it if you were 15. What some folks are trying to tell you is that it doesn't sound very constructive - just critical - especially if there is nothing positive or encouraging to accompany it and lubricate "the shaft".
Mark Twain said "that a man who carries a live cat home by the tail is learning six or seven times more than the man who doesn't do so. And the lessons and information he learns from the experience will probably remain with him for a quite a long time. And it's likely that he won't carry a cat that way again. But I say if he wants to carry a live cat that way, then let him!"
