I'm not sure of the equivalent energy to get the same effect of a stationary target as with 14Tev opposed beams, but I'm betting it's a few orders of magnitude greater.

I keep hearing talk that two 7 TeV beams will collide, resulting in a 14 TeV collision. E.g. when
cjameshuff said that a stationary, 14 TeV mBH formed by the two beams colliding that happened to get hit again by one of the beams would turn into a 21 TeV mBH, and then go skittering off into the universe. But perhaps he's wrong about that.
