South African Kai Goodall wins an international design challenge with his foot-powered washing machine.

December 23, 2021

Kai Goodall is a master’s student in Electrical Engineering at the University of Cape Town, South Africa. He is always driven by his passion for green solutions and technology. He is the only African contestant from six finalists worldwide to win the RS Components International People.Planet.Product Student Design Challenge.

The Pedal n Spin foot-cranked washing machine is a pedal-powered mechanical device (no electricity needed) that is easy to use, reliable, & environmentally friendly. He invented it for households who experience continuous electricity outages, poorer communities who can’t afford too much electricity bills, and those who choose to live off the grid. This innovation is also helpful for people interested in decreasing their carbon footprint and dependence on fossil fuels. Using the washing machine from a seated position will give users stronger leg muscles and improve posture & efficiency.

The materials are made from wood and steel components and fit the green solutions for sustainability and recyclability. Kal is working on more innovative solutions to contribute to the renewable energy sector and the planet’s sustainability. He also wants to educate and encourage his fellow engineering students and high school students to move towards green solutions.
