Easy anti-matter creation
"Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma 'jet.' This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and gamma ray bursts."
Why hello thar Mr. Fusion.
[take a gold ball filled with liquid hydrogen. shoot laser. haul ass.]
Note: 100 billion particles is something liek... a dozen attograms. You could stand on the other side of this jet and not feel a thing [untill the vaporized plasma jet of highly energized gold atoms eats through you]
