That’s scorpion as in ‘muzzle-loading field artillery,’ because that’s what this thing is. Although admittedly it uses pressurized air instead of torsion energy.
Via GeekTyrant. And let me be clear about this: this is a proof-of-concept canned-air siege weapon. At half power and a 45 degree elevation it can lob a PVC and plastic projectile 250 feet; the (blunt) missile can crack a concrete block at full strength, and point-blank range. I may steal this idea for my next Morgan Barod novel. Or at least figure out how to hand-wave it away.
