Bio-briquettes in Nepal

Not everyone is inventing things like car headlight wipers;

Some things actually make a big difference...

-This one (bio-briquettes in nepal, video) is pretty cool.

-Here's the ted link to something similar (for Haiti)

-Here's the link to engineers without borders

-and the MiT Third World Development (int'l development design) summit.

If I had technical aptitude, and a desire to really help the most people I could, I think I would try and meet some basic global needs like these people do. 

Everyone fits in the global puzzle.  There's some difficulty in finding one's place, alot, though.
