Free hot water

Use free solar radiation to heat a gallon of water for washing up, doing dishes or whatever. Put the water in a glass jar and set it in the sun for a few hours. Don't set it on concrete or other hard surface and not in the snow. If you can put it where there is a dark surface behind it, it will heat better. You may be surprised at how warm it gets.

Thanks for the dark surface part. I've tried this before and it didn't work. I never thought of putting a dark surface behind the jar. DUH to me. I'm off to get a gallon of water and putting my dark blue coat behind it.
Regards, Peg
