where is the open source idea collection?

I´ve been searching on the web for cool ideas for socially innovative projects, but did not really find anything. How come? There should be a simple list of ideas, open for everybody to take inspiration from or simply put one in action. Or do my searching skills just suck?
A simple list with the topic of: what concretely needs to be changed in my environment. Then anybody could go anywhere and do a project on such an issue. Anywhere in the world, but being sure that there is a real issue he/she is working on. Saves you a lot of research.

that´s exactly what this country needs!

No, seriously, what do we need? Let´s go and have a look. Let´s take a skateboard, cross this country and see what is there and what is not. Let´s see what people really have and what they really don´t have. Be an outsider and see things from a different angle. Make a movie, make a book, and pick one thing yourself and start doing it.

Ideas: projects, funstuff, anything. Open source.

There are so many people out there who really want to do more with their lives than a 9-5 job. Many of them are travellers, searching for a suitable way that fits their needs and at the same time makes them do something useful.
So let´s go to Brasil, stay at a youth hostel for some time and do facilitation on "what do I want to do with my life" with backpackers!
