We should ban this research immediately. Consider the nightmare if someone produces an anti-Ed. :lol:

Why did Star Trek get it wrong? They used "anti-matter", but I don't recall them ever saying it was anti-hydrogen (or anything else). Anti-protons and positrons are considered anti-matter, I think (although "matter" is pushing it).

Also, didn't the Tokamak nuclear fusion experiments rely on a "magnetic bottle"? I suppose that if they were just fusing protons into hydrogen nucleii, that would make sense.

Bizarro Ed.

Isn't it amazing you can tie just about any thread to a Seinfeld episide?

Actually, over five years ago I heard that they made the first anti-hydrogen atoms. This isn't going to be a boundless energy source, but it is a very dense one, though. In fact, it is about twice as efficient of an energy source than is usually considered possible, since it annhilates both the matter and the anti-matter. Such an energy source would be good for making nano-probes into suicide bombers for the military. (That's a good idea... Oh great... I opened a can of worms...)

Such an energy source would also be useful for interstellar travel, since you generally want to take the fuel with you, the less fuel you take the better. Of course, this is at least two hundred years in the future (that is extremely optimistic, if you look at how much energy it would take to fuel interstellar travel). More likely, however, an easier way to travel to other planetary systems will be discovered/developed (that's my opinion, anyways). Personally, I don't think that any idea that we think is probable right now will be what we will use for such a purpose. Like fusion power. 200 years ago, no one would have thought that such an immensely powerful weapon (one that has the ability to kill most of the people on earth in a few hours and make the place unlivable--keep in mind that this is the absolute worst possible case and would not be likely to happen even in the event of an all-out nuclear war) could be made from the power inside of the atom, which then was hardly more than a fantasy dreamed up by some Greek philosopher/theorist (what was his name?).

:idea:

I have a theory that the iPAQ -- by either design or happenstance -- is actually a poorly performing antimatter collection and storage device. The containment field inside the iPAQ must leak, causing a dribble of antimatter to flow randomly throughout the device, annihilating whatever components it contacts.

That would explain why I've had to use my Carepaq six times for totally unrelated failures!
