gamma ray weapons

"The hafnium explosive could be extremely powerful. One gram of fully charged hafnium isomer could store more energy than 50 kilograms of TNT. Miniature missiles could be made with warheads that are far more powerful than existing conventional weapons, giving massively enhanced firepower to the armed forces using them." Link

sounds like a pretty sweet weapon to me

Yes it seems like a nice weapon, but i really dont want to see another arms race..the more powerful weapons become the less chance this planet has of survival. (Said like a true hippy )
