Startup Idea : Universal web database

You want to store somewhere your experience. You need some web database which you can define, modify, fill-in through web user-friendly interfaces. What will you use? google freebase? wiki?… Problem No. 3: Imagine that you are teacher and you ask your students to collect information about solar energy: technologies, companies, products, persons, events etc. From various sources.
