The Towa by Guldkannan is a ingenious green invention that seems gross at first, but quickly proves itself to be a startlingly effective alternative to traditional store-bought fertilizer.
Whereas nitrogen-rich factory-made fertilizer causes a host of problems with runoff woes and energy-intensive production, this easy-to-use and entirely sustainable product uses human urine to do the dirty work of fertilizing -- an awesome innovation that will save you money and save the environment from some otherwise carbon-intensive fertilizer production.
Implications - The alarmingly unusual fertilizing tool comes equipped with a detachable spout which optimizes its compact air for collection. Users can sit right on the easy to use pot, which is said to support over 300 pounds.
