Hello,

I am starting to suspect "ground" for PC's does more damage than good.

Perhaps the "ground" leads to a "backdoor" for electricity to do damage.

Therefore instead of dumping energy into the ground wire an alternative
could be found.

For example some kind of circuit which transfer the energy into heat.

So that the energy is dumped into the system's air.

This way PC's no longer require a "ground" and there is no longer a
"backdoor" for damage.

Bye,
Skybuck.

This alternative would be especially usefull for environments which don't
have a ground.

Like my living room or perhaps international space station ?

Does ISS have a ground ?

How about laptops ? Do they have a ground when not plugged in ?

How about iPads or iPhones ?

Bye,
Skybuck =D

Oh really,

Sounds like you making a joke ?!

But just in case your are not, provide some proof/documentation of these
"facts" !

It does raise the interesting question, why PC's need ground and everything
else does not.

I was thinking maybe the excessive stuff is stored inside and later
dispossed when charging.

But what if a device would not need any charging for a long time ?

Bye,
Skybuck.

In case you are making a joke I will add to it:

"It is not disposed it is exploded into your head when the battery
explodes".

Bye,
Skybuck.

They use the human body. The ground is that
warm spot on the bottom.

The ground is in the earpiece. Excess electricity
is passed into your head.

Your assumption ("everything else does not") is false.

My assumption is true.

Everything should work without ground because not everything has grounding
power wall sockets.

End of story.

I don't suppose there is any remote possibility you might consider
actually spending five minutes learning the faintest smidgeon about the
topics you post on before you post? Or at least quit using new accounts
so you'll quit escaping my killfiles?

Didn't think so.

The unit will work, but any fault condition may kill the owner if there
is no safety ground on the external metal chassis and it goes live.

Yes. Sooner or later you will kill yourself using kit with no earth.

I think one time, long ago, I tried running a PC with just a plain
(non-grounded) extension cord, as I had nothing else at the time...

however, it seemed to have fried the power-supply or something, as the
thing didn't turn-on after this. this was back in the days when the
power-supply switch was still mechanical (before ATX and its
MOBO-controlled power), and if one hits the switch, and nothing happens,
then the PSU is not happy...

granted, thinking of it now, there could have been a safety fuse or
something, which would blow if one tries to use the PSU without a proper
ground.

That would actually be a "permanent killfile" for this bozo. I'm tired
of constantly adding new usernames to the "Skypuke Flailing" entry.

Why did you have to warn him?

He *still* knows nothing about electricity, this thread is almost a
script rewrite of his "Is it possible to die from a battery ? " post in
sci.electronics.design from Aug 5 2005.
