Every day, I take a shower to get clean. Sometimes two if I'm working hard. This uses a surprising amount of water. With more and more of the country facing drought, there must be another way.
Well, one way would be to recycle and purify the water. It's been done, so I'm off to the crazier methods.
How about I copy the space program, and have a cleansing foam sprayed onto me, and then vacuumed off? It would use no water at all, and in theory the foam should be recyclable. Waste that it pulls off of me could go straight into a garbage can for easy disposal. Or, alternatively to that, an incinerator. Easy fuel source.
