The article was interesting.
I didn't know antimatter can be that useful!

This is interesting from the
link:
A millionth of a gram of antimatter is so small "you couldn't even see it on the head of the pin," Smith says. Yet it contains enough energy to propel an ultralight robotic aircraft "around the world three times without refueling...Howe and his colleagues have calculated that with 17 grams of antimatter -- barely enough to hold in your hand -- a robotic space probe could get to Alpha Centauri in 40 years.


This should be the ultimate source of space travel.

While researchers ponder on the question of how to store anti-matter,they need to redirect their attention to the production of it. A large amount of anti-matter is actually produced only to be destroyed shortly afterwards when it comes in contact with ordinary matter. Only a fraction is harvested and research conducted on. When I said redirect their attention to the production of it, I meant it should be used as soon as it is produced eliminating the need to design a facility to store it. Upon being produced, the anti-particles and ordinary particles would readily attract, so the problem there would be to contol the flow as to where an over abundance of materials is not introduced where the results be catastrophic. Another problem would be the extemely high operating temperatures. Materials Engineers would have to develope a material that could withstand millions of degrees Fahrenheit (highly unlikely) for prolonged periods of time on a very small scale, because engines the size of lets say, an ordinary Pringles can could put a fully-loaded space shuttle into LEO on less than a gram of this stuff. And then on top of this, build particle accelerators small and efficient enough to carry its weight, a containment field generator, a power supply for accelerator start-up and a way to sheild all the lethal radiation away from human operators of this craft, if any. This is highly volatile substance, in any form (i.e. positrons, anti-neutrons,anti-protons, anti-muons etc...), so the devices that produce would have to highly regulated to keep it out the hands of those who would want to make it into a weopon. For right now, it does make good science-fiction, don't you think?
