Antimatter is a fuel source that produces huge amounts of energy. Theoretically, 1 gram of antimatter can heat 1kg of water to a temperature of about 20,000 times the temperature of the core of the sun. why doesn't someone find a way to make it? I thought that if you fired a gamma ray at helium, you could possible make some positrons (antimatter). to find out more on antimatter, check out wikipedia. post alot plz

I have heard that the energy of anti-matter is far more expensive to produce than it could release for general purposes. There is, then, the problem of containing it as it explodes violently in contact with any ordinary matter.

in responce 2 sands-but it would cost less if the gamma thing works and it would be in a vaccum suspended by mangnets so it would'nt touch anything

Here is an article on magnetic suspension. http://www.iat.jaxa.jp/res/arg/0c00.htmlAs you can see, it works with magnetic material. There is no indication that anti-matter is magnetic.

Antimatter is hellaciously expensive to produce at the moment, requiring the use of a large particle collider. We are specifically talking about antiprotons, not positrons (antielectrons, which are, relatively, a common occurrence). Yes, you can do all sorts of stuff to generate positrons. No, it won't help you make a ton of power. Not enough mass to be worthwhile, as annihilation is a matter to energy conversion. Particle colliders also require a huge amount of energy and upkeep to run. We current expend a vast sum of money and a large quantity of energy to create a very small quantity of antiprotons.

Antiprotons require a great deal of effort to create, and then store. Antiprotons are confined through quantum electrodynamics - it is a simplification to say it's confined by "magnetism" or "electricity." Since the antiprotons are ions, they DO have a net charge to them and thus will react to electrodynamic fields.

Third, antimatter is unstable. It doesn't like normal matter. If your containment method fails and you have a substantial quantity of antimatter, your facility and the surrounding area will undergo rapid redecoration.

The real problem is that antimatter is not actually a source of energy at all. It is only a potential energy storage medium. Energy must be used to make the antimatter, then when it is destroyed the energy is released. The energy must originally come from another source. As a storage medium, it is not very practical for most purposes because there is no efficient way to either make the antimatter nor an efficient way to reclaim the energy once released. The only advantage of antimatter for energy storage is that it has greater energy density than any other known medium. This might make it useful for bombs or possibly fuel for vehicles such as space craft, but not much else.

I happened to be reading http://en.wikipedia.org/wiki/Antimatter the other day.

Another problem is safety.

If you think nuclear power plant accidents are bad...

The reaction of 1 kg of antimatter is the equivalent of a 43 megaton bomb, according to the wiki page above.
