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


Horses sweat.

In summer you're ****ed,


Nope, sheep doo fine even when its 45C etc.

which is why cats doze off all the time.


Nope, they do that all year round.

And even you should have noticed that
there are a lot more monkeys and baboons
and gorillas etc in the hotter areas of
the world than the cold ones.
