Washing machines can cost hundreds and even thousands of dollars a year to run depending on your washing machine type, whether or not you use hot, warm, or cold water, your energy company’s prices, water company’s prices, and the number of loads you run per week! Most significantly, roughly ninety percent of the energy used by washing machines just goes towards heating water!1
So, how about a bike pedal-powered washing machine? Currently, there are many different designs and ideas for pedal powered washing machines. The goals differ, but they include reducing energy and water consumption and costs, and increasing accessibility for people who cannot afford and/or do not have the energy capacity to own conventionally powered washing machines. By now you are probably wondering how you can manage to get your hands on a pedal powered washing machine... Unfortunately, at this time there are no pedal powered washing machines available for mass production and thus for purchase by consumers. However, if you are handy with tools you can build your own!
