Future of Engineering

This article appeared in the HSU Lumberjack newspaper in 1997. The article is based on an interview with the pedal powered washing machine designer, Bart Orlando. Since then, the pedal power drive line of the washer has been simplified. The number of fanbelts used has been reduced from two belts to one belt. Now, one fanbelt connects the flywheel of the exercise bike directly to the pulley which drives the transmission of the washer. This reduces the amount of friction by eliminating one belt and two pillow blocks. Less friction translates into less pedaling effort.
