It doesn't do inventions, just finite/limited art project financing; it's not really for money making, if you make money, that's great but it's more to cover costs so one can "do" a project in the first place. For example, a guy on the front page has won a place in a show in another country but doesn't have the money to get there so is getting financing to get there. It is a neat idea.
