Friggin' amazing. Of course, if this had been shown in mideval Europe, the scientists would probably be demeaned as "Servants of the Devil!" and burned at the stake. Hell, that'll still probably happen...

So? Here in NB we've already got Reversing Falls and Magnetic Hill.

That's, to use the word of Dr. Linke, "neat".

Very cool. I think it just goes to show that even laws of nature have loopholes.

It's called capulary action.

No it's not. You're thinking of capillary action, but that isn't what's happening.

It works on the same principle.

It works on the same principle.
Capillary action or capillarity (also known as capillary motion) is the ability of a narrow tube to draw a liquid upwards against the force of gravity.

Where is the narrow tube in this experiment?

It works on the same principle.
If capillary action works on heating up water, sure, yeah.

Hmm... no, this appears to be an example of the Leidenfrost effect not capillary action.

That's rather ingenious. And very convenient.

If you heat up water enough, it flies. :D

If I set Lunatic Goofballs on fire, maybe he will fly.

there is only one scientific way to find out

all this scientific work can be made obsolete by me putting a bottle of water on an escalator (going up or even.....down!) highpoint of someone’s career I suppose:p

My god, man. Wouldn't you? :eek:

I know a faster way than using one drop of water to slowly climb a hill.

Get a bucket, fill it with water, and dont be lazy - haul it up the hill.

Now you have millions of water drops at the top of the hill much faster.

Or you can set a bucket on top of the hill and wait for rain. :)

My god, man. Wouldn't you? :eek:

I've just pictured you floating in the air, flapping your arms frantically while on fire. Brings a tear to my eye; science is awesome.

Anyone have a light?

Fortunately for me, mud doesn't burn. :)

Yeah, but Napalm does. :D

I'm confused as to how this would cool down a computer's system, as they say this could eventually do.

Wouldn't the water just move around, but remain very hot, if not a vaporized form?

I'm not sure of the effects of sealing off a metal container and filling it with water (not in that order of course) and heating it up... wouldn't that create some kind of pressure cooker?

I'm just not sure where the cooling action is coming from here - I understand the use of water, but if the water is steaming hot, how useful will it really be?

Wow... Now all that is left is to make pigs fly (although that will invalidate a perfectly good saying), and we will have defied all the old assumptions about natural laws.

Put all the right-wingers underneath him, and start talking about Hillary for Clinton in '08.

Enough hot gas to fill a blimp. :)

Once I got some altitude I'd poop on them. :D

Woohoo! You'll get the "splatter" angle!

It happened on the Simpsons...

just a guess, but i'm thinking the water will evaporate, but condence and collect in a pool that will then use this principle to recycle the water in the cooling system.

Many chips have cooling circuits nowadays, but these require pumps to drive the coolant, which in turn generate even more heat. using this newer method would get rid of the need for a motorized pump, and therefore the extra heat.

woah, i didn't click "quote" on the post right before mine, but it did anyway. fixed.

Actually, it happened on tour with Pink Floyd!! :eek:
Hundreds of people saw it. It was even included in one of their album covers.

You know, EVEN THAT was a matter of contention between Rogers and Gilmour. :(

Pigs flying is easy. All you need is a catapult and the pig.

What is so special???
Just use a freaken hollowed tube and a spiraled shaft.

The point isn't that they made it go uphill. The point is the application of the new method.

The electrical currents now passing through microprocessors are so large the heat they generate can limit computing performance.
Many chips have cooling circuits nowadays, but these require pumps to drive the coolant, which in turn generate even more heat.
Suitably micro-patterned channels, argues Dr Linke, would make the coolant flow automatically.
"It would be very neat if we could use the heat from the chip to be the pump, because you would not need any additional power, but also because the pumping only happens when the thing is warm; it would also be a thermostat at the same time. So it would all be in one package."

That isn't impressive.

Yes it is. It will provide a direct stream of coolant to the hottest part of the processor. The cooling will also act as a thermostat. It's amazingly convenient.:rolleyes:
