Plans for antimatter Fermilab is now the only place in the world to make and collect antiprotons. Going flat out we are able to collect about 5 trillion per day, to inject into the Tevatron collider. Capturing even a few of these in a "magnetic bottle" is extremely hard, but suppose we could capture all of them. If we then let them annihilate with matter, and converted the resulting energy into electricity with 100% efficiency, we could light up a 60-watt bulb for 25 seconds. The power bill to do that would be about 50 megawatts for a day! So antimatter bombs or antimatter-powered spaceships have absolutely no scientific foundation, unless we could suck them through a wormhole from a parallel antimatter universe!
