Scientists from Singapore's Nanyang Technological University aren't keen on being wasteful -- that's why they've developed a toilet that uses 90% less water than other commodes and is capable of generating energy. Aptly named the No-Mix Vacuum Toilet, the porcelain pedestal's pot divides waste between two partitions -- one side for liquids, the other for solids -- and uses vacuum tech reminiscent of airline lavatories. Flushing solid and fluid wastes with 1 and 0.2 liters of H2O, respectively, the can will be able to route refuse to external processing facilities. Fertilizer ingredients such as nitrogen, potassium and phosphorous would then be harvested from liquids. Similarly, methane can be coaxed from solids for conversion to electricity or as a replacement for other natural gasses. Two of the university's restrooms are slated to have the toilets installed in the near future, and the team expects the thrones to roll out worldwide within three years.
