Energy to matter?
One of my friends recently talked to me. The first thing he said was, "Energy to matter." He said it in the way he talks when we're planning on building something dangerous, unlikely to work, and quite possibly FBI watchlist-worthy. Though I know it's been looked into before, this got me thinking: does anyone have any ideas on practical applications of the equivalency between energy and matter? (aside from the atomic bomb--e.g. Fabricators that carry hundreds of products' worth of materials in a small, energy-dense source, like a battery?)
