Gadget That 'Eavesdrops' on Water Warns You of Waste

A sleek, white gadget that looks more like a trendy speaker than a tool for water conservation could stop people from wasting precious H2O, said one Silicon Valley startup. "I know more about the sound of water than you'll ever believe," said Baback Elmieh, founder and CEO of Nascent. The device, dubbed the "Droppler," is like Shazam (an app that can identify artists and song titles just by hearing the music) for water, Elmieh said.
