Water is the source of all life, there is a world water crisis, and millions of people on the planet do not have potable, clean, drinking water. My guest this week, Paul Lazarus, director, writer and producer of film, television and theater has directed a wonderful documentary entitled, Slingshot. The film focuses on the the current global water crisis, and the path that inventor/engineer extraordinaire, Dean Kamen takes to bring his water purification system to the world market. The documentary has won film festival awards, and is a must see movie. For more information, go to www.slingshotdoc.com
