Human powered pedal washing machine has been designed using materials suitable
for its application. An existing bicycle was used as the pedal and other parts of the machine such
as the drum, the frame was fabricated using galvanized steel. The material selection was put into
consideration, such as corrosion because of the machine’s involvement with water. The human
powered pedal washing machine was tested with a used dirty Laboratory coat. The pedaling
washing was first done for the first 15 minutes, using water and sunlight detergent soap. There
was a partial cleaning of the Laboratory coat, though the coat was very dirty. Another round of
washing was done after which the first washing water was drained out through the outlet part of
the machine. The second washing was excellent because the Laboratory coat was clean. The
human powered pedal washing machine performed well with all the designed parts functioning
well. This is an eco-friendly machine, maintenance cost free, energy conservation machine and
highly sustainable for underdeveloped nations of the world
