Museum of Science and Industry


Good news! The energy crisis could soon be over! Yes, all of our energy problems may soon be… behind us. Because scientists from Nanyang Technological University have invented a toilet that turns human waste into electricity! Yes!

Manually separating waste for processing is time-consuming, expensive and gross, which is why waste-to-power technologies have so far failed to catch on. The main advantage to this new toilet is that different types of waste are separated and processed on-site, rather than in a separate facility. Liquid waste is harvested for fertilizer components, and solid waste is digested by bacteria to produce methane, which can be used as a replacement for natural gas for cooking and generating electricity.

A local example of energy not going to waste (but waste going to energy) is Chicago's Stickney Water Reclamation Plant. It uses power created by burning the biogas from the waste it treats.

So in a few short years, we could have electricity coming out of our EARS! Well, not our ears.
