The headline of the article on CNN.com says “Futuristic Water-recycling Shower Cuts Water Bills by Over $1,000.”
I like to save money and be green, so I read the article and admit I am impressed. The shower is a closed-loop system. Hot water flows out of the showerhead, falls to the drain where it is purified to the drinking water standard with a nano-ceramic filter and heads right back to the showerhead again. It all happens very quickly and the water for the most part retains its heat. The inventor claims it saves 80% in energy costs and 90% in water usage. In fact water usage for a 10-minute shower is about 5 liters where a regular shower would consume about 150 liters.
