Clothes Drier.
Mine runs at about 60-80rpm. Thump thump thump. And around it goes beating the stuffing out of expensive duds. All that heavy clothing also takes a lot of electricity to pulverize. No wonder the bearings on these things don't last.

It would make a lot more sense to have more air and far less spinning, like mother nature.
Maybe only 5 rpm, or spin up every two minutes or so.
If a heated routine is required, this could be done in cycles as well or tapered off at the end of cycles.

Washers (clothing and dishes)
There are three phases to cleaning: large particle removal, clean cycle, final clean rinse and/or dry.
Everyone knows that applying heat, liquid, and surfactant and then just letting it soak is far more efficient.

I leave dirty cloths in the wash machine, with a small amount of detergent, and an hour later the water is pitch black.
Then I add more detergent and run it through.

Machine in the USA these days just plow through the routine at the same speed.
Bam bam bam. Back and forth the agitator moves at 120hz churning the water and clothing into froth.
Maybe the better machines have these soak cycles, but I haven't seen them yet.
The washing machines in Japan move a 1/4 turn every 5 seconds instead.

With the droughts these days, I'm thinking the washers of the future will use water misting with ionizers or sonic vibrators instead to shake the dirt loose.

What say yea?
