5-Gallon Jug

Designs On— Global Warming

By John Lai and Afshin Mehin

This concept is built on the premise that knowledge inspires behavioral change. A digital in-shower display in the familiar shape of a five-gallon water jug reflects water usage from an in-line flow meter (that generates power for the display). At a rate of five gallons per minute, an individual in the shower for 15 minutes will see they’ve consumed 75 total gallons, or 25 five-gallon jugs!
