A Clean Stream

A San Francisco company that, as far as I can tell from its website (http://hyphae.net/journal/) does amazing green-related things just about everywhere, has come up with the ultimate portable public urinal and sink (that can be used by women, too). The PPlanter has an attached biofilter that takes in the nutrients, protein, and carbohydrates and leaves only salt behind. It's already passed the test in a crowded San Francisco neighborhood, and the city has ordered a permanent one: http://www.newscientist.com/article/dn25108-toilet-planter-urinal-uses-bamboo-to-deal-with-waste.html#.UwvE5l6jXgc
