m50d got it right. If this had worked, there would be no need using electrolysis and all that stuff. Just fill a pipe with water and put a balloon (or something else with mass between that of air and water) in the system. The balloon goes into the pipe at the bottom, exits at the top, falls through a turbine and goes into the pipe again. Voilá, endless energy. Sounds a bit suspicious, doesn't it. The catch is of course, as m50d spells out, that the balloon cannot enter the pipe without expending energy.
Just FYI, the coeffecient of performance of a system can be over 100%, as long as the system is not closed. That is the case in a heat pump, for example. Likewise, an external field could be used to raise the COP of this machine over 1.
However, the first statement reveals this machine as pure nonsense anyway.
Hawking radiation does not demonstrate perpetual motion in any way.
A quantum fluctuation can be seen as a particle and anti-particle popping into existance next to each other. If this happens at the brink of a black hole, and the anti-particle falls in, the particle goes in the opposite direction and can be observed as faint (Hawking) radiation. However, the antiparticle decreases the mass of the black hole, eventually causing it to evaporate, after billions of billions of years. Compare it to solar power - the radiation stops when the black hole runs out of mass, and the sun stops shining when it runs out of elements to fusion. The former is countless magnitudes harder to harness though, due to the low intensity of the Hawking radiation.
All in all, during hawking raditation, the laws of conservation of energy and momentum are conserved, and it doesn't go on forever either. E.g. there's nothing "perpetual" about it at all.
I'm in the same boat as you, never got it working. Eventually I installed it on the computer at my summer place, it dual boots win 98 and xp precisely for games like this.
However, the other game modes, beside Shandalar, still works. Draft is quite fun.
He means Krypton. It's number 36, and is a noble gas, and therefore very unreactive. Kryptonite is therefore very unlikely to exist (you haven't ever heard of "heliumite" or "neonite", have you?).
The light doesn't literally bend "around" the object (as in, in the air surrounding the object), but enters the top layer of the object, bounces around, and exits on the other side. Therefore, standing on the ground won't be a problem.
Actually, cold fusion was never about perpetual motion. If it was, serious scientists would never even have shot a glance at it.
The point the grandparent is trying to make is that it is a giant leap from cloaking one wavelength to cloaking all. The existing approach just doesn't cut it; they'll need a whole new idea to make it even theoretically possible.
Are there really infra-red equipment (except lasers, which are already covered in another post) that depends on just a single wavelength? Cameras that can "see" infra-red radiation (e.g. heat) operate in an entire section of the infra-red spectrum. You know how images from infra-red cameras tend to show red for hot, blue for cold, etc? Well that's different shades of infra-red for you (translated to the visible spectrum so that we can see the difference).
Actually, the article in the magazine was about bending light in the microwave spectrum (which another \.-article covered quite a while ago). Not until now have they managed to do the same in the visible spectrum.
I have yet to come across a printed magazine with fresher news than slashdot.
Briefly explained: As the ball's velocity increases, so does it's mass, thanks to special relativity. That means it will take more time to accelerate and you will never actually reach the speed of light, no matter how long the slope.
In addition, seeing all those chickens at once will slow everything down to a crawl until you manage to escape.
Not only are they super chickens, they have time-warping abilities too!
Those links only contain samples ala a few hundred kilobytes, no different from what for example iTunes or amazon.com offers. They seem to be legal for some reason.
In addition, "Frozen" contained no Madonna, only the background track. Strange.
Interesting. In addition, why not use GPS to note down the position of each and every mine when you place them, and store the locations in a database? That way, once the war is over, if some of the mines failed to report that they initiated self-destruct, you could just go out and remove those manually. It shouldn't be so much hassle if you know exactly where they are. Of course, that may already be the case today.
Of course, having the mines jumping around will screw this idea up a bit.

I've never realized replying to your own post makes you Jesus.
So THAT'S why you shouldn't double-post. You can end up being crucified. Gotta watch those code tags...
Whoosh.

You make a very good point. Similar thoughts have crossed my mind, but I've not been able to word them as well as you have.
If they're calling you and not vice versa, you're not paying them a $1.95/minute phone bill. E.g. not much of a business model.
I see this the opposite way. If people rode bicycles more, they would be much healthier, and heart attacks would be less of a problem.

"... low energy nuclear reaction (LERN)" Someone needs to LERN to abbreviate correctly. (-:

No, because the Z- (and Y-) cloak is visible to the X wavelength, this won't work.

Duh. It had a "+8 piercing damage to nerds" modifier.
He's got the ultimate proof this story is a hoax, hands down. And he did it without juggling a lot of numbers.
