So what do washing machines use, AC or DC?

Water and some sort of cleaning chemicals dependent on personal choice.

A few years ago Which? reviewed a washing machine that didn't use
detergent: it sort of passed an electric current through the water.. I
don't know how good it was: apparently washing normally with detergent
uses some kind of electric charge to clean fabric as just passing the
water through the fibres isn't enough to remove the dirt.

Do you have a link? Google ain't working.

For the latter, I was thinking of the following - click on "show

This amused me!

"But theres another surprising advantage of not making lots of fur. Fur is made from proteins. If youre not putting your protein into fur, well, you can use it to bulk up your brain. Maybe losing our body fur made us into the clever folk we are today."

So I was right, hairy folk are Neanderthal ****wits.


yes and why most of us have evolved without fur, which is a trade-off which means we get cold quicker, because the energy we used to use just to keep us warm now goes into feeding our brain rather than wasted in produciung heat.


Bull****, we can produce heat as and when required.

Only to a limited degree that's why lots of explorers died at the North and south poles over the years.

But with fur, you can't cool down with sweat.


yes yuo can, through a tongnue or nose and eleephantsb use their ears.

In summer you're ****ed, which is why cats doze off all the time.

So they don;t have to waste energy to heat themselves unlike you which means less energy for the brain, which can be used for other things, which is why the human being in general is the most evolved species on the planets because of the brain, but I can understand why you are jealous. So why not learn from superior inteligence of teh human race rather that sit in a stream of cold water and thinking you've evolved more than everyone else as most of us don't see the point unless it;s some sort of festish you have.
