My New Idea: Genius or Madness?

This has been buzzing around in my head for a while.

Did you know that the average shower head uses about 5 gallons of water per minute? Per minute! And don't forget the energy use of heating that water and keeping it hot in the tank. So, I was thinking, how about getting four solar shower bags?



That way, nobody could complain that their sibling had forgotten to fill the bag up, or that the available bag(s) had been used up. Today, I did a quick search to get an estimate of the price range we'd be talking about. They are between $15 and $20 each.

We could use them for most of the spring, all summer, and the first part of the fall.

How about that? Eighty dollars to train wise shower usage and save energy. (Plus, we could take them with us when we backpacked or camped...)

What's the verdict? Genius or Madness?
