Bart
Orlando demonstrates that one person has the power to wash clothes in a pedal
powered Wringer washing machine. The wringer eliminates the spin dry function,
standard on modern washing machines. One person can do 1/3 of a normal load of
laundry in about 30 minutes.
| An
exercise bike is substituted for the orignal 2hp 110v electric motor. A fan-belt
is rapped around the flywheel of the exercise bike and a pulley which drives the
original transmission of the Wringer Washer. | This
version of the pedal powered washing machine features the addition of a pedal
powered permanent magnet electric generator that can supply electricity to a 110v
blender. The female end of an AC extension cord is wired to the positive and negative
leads from the DC generator. The generator output is approximatley 110 volts-DC
at 1100 rpm, while pedaling at about 90 rpm. Most household blenders have universal
motors that run both AC or DC. |

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. | This
CAD diagram of the pedal powered washing machine was made by Matt Rhode as a class
assignment for a course he took at HSU in computer assisted drawing in 2000. Students
taking that course are incouraged by the instructor to choose CCAT's pedal powered
devices for the subjects of their CAD drawing assignments. In this way, the
engines of the university are harnessed to advance the work of CCAT. This
diagram, of the CCAT pedal powered washer (designed by Bart Orlando), was submitted
to Home Power magazine in 2001. | When
Arcata became the first city in the United States to elect a city council with
a majority of Green Party members, People magazine printed an article which featured
this photo of the CCAT pedal powered washing machine. |
