I have 50 washing machines and 50 cloths driers that don't work.?

You could go into "mass production" making these lamps

which I think look actually quite cool!

You can contact a pottery club. I know artists who use old washing machines or dryers to build a so-called Raku Oven.

Finally, take them to bits, make sure which parts work, and sell them separately on eBay. Sometimes people are hungry for such hard-to-get spare parts....

Having taken a couple washers apart to repair, I have to say they they are actually remarkably simple machines. Even different brands come apart the same way and have the same 4 or 5 components. The tub, transmission, motor, pump and controls. I bet you could take parts from the 50 and make at least 25 working machines yourself.

I haven't tried a dryer, but I bet you could do the same.

There are web sites that you can google up to tell you how to take them apart and what to look for in an inoperative machine, based on what it doesn't do.

I would stop collecting them if I was you ! It is not a good idea to re sell electrical devises unless you are able to offer some sort of test certificate and guarantee. You may find yourself liable. You can maximise the scrap value by breaking up the machines into the different metals before selling but this will take some time.
