In today's podcast, Cathi Bond talks about the Nano Membrane toilet, designed for use in situations where there are currently no toilets. It's an inexpensive solution that doesn't require water, and yet produces (grey) water and power (via Gizmag).  

Meanwhile, Nora Young mentions the MyMe camera and personal digital assistant, a sort of Siri-meets-Google-Glass device that you wear unobtrusively around your neck or on your belt (via New York Times). Would you wear something like this? Leave us a comment!
