You do all you can to help the environment. You recycle, use compact fluorescent bulbs and even keep your home slightly balmier than you'd like on a hot summer day. The one thing that's really hard to tone down? The nice long shower at the end of a hard day. Four Industrial Design students from Turkey feel your pain, so they developed Washit.
Washit is a shower and washing machine all in one. Two waters pumps, three different kinds of filters (carbon, organic and chemical), UV filters and a water heater make up this double-use appliance. Don't get weirded out, here's how it works: The shower stall takes gray water that collects at the bottom during a shower, filters it, puts it through a UV cleaning phase and then sends it to a water tank. When a user wants to do laundry, she can access the washing machine from outside of the stall and use the filtered water to clean her clothes.
