I don't by any means live an electricity-free life, yet, but more than any other household item, I think I would miss the washing machine the most.
Sweeping with a good broom is a good alternative to vacuum cleaning. Washing dishes I do by hand anyway. Cooking is possible with gas, wood, or even solar cookers, if you want to get fancy.
But washing machines present a particular problem. Clothes need to be washed long enough and with washing detergent, which is both tough on your muscles and tough on your skin. In those parts of the world where washing machines are rare, the task of washing clothes can take several hours for the washing alone, many more hours/days for the drying process. And the washing on washboards is also not good for the clothes.
Are there any good alternatives to commercial electrical washing machines?
