A very cool scientific invention. A water pump that uses a small turbine to generate enough electricity to electrolyse a salt solution and provide chlorine to instantly disinfect the water!
"The amount of chlorine in the water always remains steady; if the tap is opened further, the stronger flow powers the turbine faster, producing more electricity to deal with the quicker side-flow of water which has dissolved more salt. The extra electricity results in stronger electrolysis and produces more chlorine. In short; the Turbokiller is a self-regulating system, no complicated controlling equipment is required."
