Bike powered washing machine

I searched for something like this in the forums but couldn't find it.

Generating electricity with pedal power as pretty in efficient but using direct power to turn say a 55 gallon drum with sun warmed water seems pretty doable.
Here is a good design =>

That would certainly do a larger load than the Wonder Wash, but then it also takes up more space. It also appears to be missing the same thing the Wonder Wash does, which is a way to wring the water out of the clothes after rinsing. If that has a way to spin-dry (or mostly dry to the point they can be hung up without hand-wringing) then it seems a winner, at least for the summer.

And another "spin" on a bike powered washer....

Awesome,

nice spin cycle!

The secret is to have a sealable drum and use hot water. When you turn the drum pressure builds up and forces the water through the cloth. I used to have a great little hand cranked washing machine that worked really well, and was just a sealed drum on a stand with a handle. I found if I chucked it in the back of the station wagon and drove to town and back it worked just as well.
