Research Engine

AITOOW wonders if there is a worldwide compendium of research projects/studies that one can search BEFORE they begin one? It should be like a marital registry. You check off the item when you "buy" it. I seem to be hearing about findings from studies that I swear I've heard of before. I know these studies are more about "employing" intellectuals than improving the human condition, but, it would be nice to have some oversight. And perhaps it could save the few legitimate truth seekers from duplicating work. If academia won't do it then smart philanthropists should or demand that it be done. Our species can hardly afford to waste the money or the time.
