Ashok Gadgil Innovative Lives Presentation and Interview
Summary
Original, master, and reference videos documenting an Innovative Lives presentation and interview with Ashok Gadgil, inventor of the UV Waterworks disinfectant unit.
Biographical / Historical
Ashok Gadgil, was born in India and is a physicist at the Lawrence Berkeley National Laboratory in California. Gadgil invented the UV Waterworks, a water purifier that provided reliable, inexpensive water disinfection for the world. The UV Waterworks uses ultraviolet light to kill waterborne pathogens (bacteria, viruses, and molds) and thus purify drinking water. The key to this invention is the effect ultraviolet light has on bacteria and viruses--it triggers the formation of peptide bonds between certain nucleic acids in the pathogens' DNA molecules, which robs them of the ability to reproduce and renders them harmless. Water, powered by gravity, flows down through pipes, passing into a tray where it is exposed to twelve seconds of ultraviolet light before it flows out a spigot. Gadgil used sheet metal, UV lamps, and stainless-steel piping to create this invention.
