"SlingShot" focuses on inventor Dean Kamen (Segway Human Transporter) and his 15-year quest to solve the world's safe water crisis. Iconoclast, Kamen, is a modern hero. His inventions, mostly medical devices, help people in need and ease suffering. "SlingShot" is a film about an indomitable man who just might have enough passion, will, and innovative thinking to create a solution for the planet's biggest challenge. Fifty percent of all human illness is the result of water borne pathogens. Kamen has invented an energy efficient vapor compression distiller that can turn any unfit source of water into potable, safe water. "SlingShot" traces the story of Dean Kamen's water purification machine from its earliest development through recent trials in five schools in rural Ghana and beyond..
