Perhaps this is a little off-topic, but I'm convinced we can save a lot of water by replacing showering with steaming (followed by super short shower to rinse). I recently bought a facial steamer for allergy issues. 50ml of water get's me more steam than I can bother to use. I'm usually done with 20ml.

I can't help but imagine that 1L of water would produce plenty of steam to clean us off. If we then have a quick shower, say 30 sec. Not only are we saving water, but probably also time, and you get a much cleaner, fresher feeling.

We use about 35L of water to shower per person each day (I know I use more), and assuming we have 1 shower a day (I generally have 2), then we are roughly saving 30L/p/day.

We use about 120L/p/day so saving 30L is a 25% saving. Now that is pretty big.

I'm not pretending I know how to get everyone to steam instead of shower - perhaps Las Vegas hotels could include steamers, and encourage people to steam followed by a super short shower. But just saying if we wanted to make our water last longer, we do have a way that doesn't involve loosing anything of real value (I'm assuming everyone agrees that a quick steam is equivalent to a shower).
