In this article from NewScientist, we learn about a new possibility in the laser field, a gamma-ray laser.  All you have to do is to (somehow) have “an electron hook up with its antiparticle, the positron, to form positronium” and then have the “positronium atoms merge into a kind-of a ‘super-atom’ condensate” which could then lead to “gamma-ray lasers a million times more powerful than standard lasers”.

No problem…

I fully expect to see at least two of these in next year’s Space Elevator games 🙂
