A simple shower warning device that turns red when you’re in there too long
Fast Company: Sprav, a smartly designed water meter to address the water and energy wasted in long showers, was invented by engineering students Craig Lewis and C.J. Valle, along with Cleveland Institute of Art alumnus Andrew Schad. So far, the team has raised more than $18,000 of its $80,000 funding goal via Kickstarter, and is attracting attention from some big names in the tech world.
