Wash Your Clothes While You Work Out with this Bicycle-Powered Washing Machine
I know for sure that my homesteading friends will love this one. I personally have no energy to do this after a long day at work but I see that this washing machine could help a lot of people stay fit and use a lot less energy.
Thinking about it, this washing machine would be perfect for people who live off the grid. The excess energy can be used to power a screen to show you the progress or stored into a battery. I really like this a lot. Check it out.
