Daniel Yeh is an engineer and associate professor at the University of South Florida and his passion is... waste water? He believes that one man's waste is another man's treasure. Listen in as he tells us more about smarter ways to purify our water whilst generating greener energy. Also, how in India you might get a little Bollywood with your bowel movements.

Featuring Parmvir, Daniel and music from La Lucha (find more of their music here) this particular episode is something of a reunion for a number of TEDxUSF speakers. Thanks as always to The New World Brewery and Billy for humoring us.
