Free hot water
A barrel or bucket painted black or other dark color, filled with water and set in the sun (even in the winter) will absorb enough solar rays to heat hot enough to wash dishes, do laundry, or even bathe. It may take a few hours, so keep an eye on it and move it if necessary to keep it in the sunshine. Alternatively, stretch a long hose across a sunny lawn (even on a warm winter day as long as you keep it up out of snow) will heat water in a few hours.
