Bike-powered washing machines aren’t a new idea. It’s fairly simple — an exercise bike collects energy as the person pedals, and the charging battery then powers the washing machine. Supposedly 20 minutes of work is enough to wash one load of clothes on cold cycle. The idea of using human power to get off grid even a little bit is tempting — and of course gyms are becoming quick to harness the power of people exercising. But could it work at home? How effective will the cleaning be? That depends on how good you are at cycling, isn’t it! Would you use it? Or better yet, would you convert your existing washing machine to run on pedal power?
