Prodigy
You have to give them kudos for creativity - a company called Invocon plans to unveil their latest weaponry at the the Navy's 2007 Opportunity Forum. Among their non-lethal weapons, Invocon will showcase their Vomit Beam - a Radio Frequency that is beamed through walls causing extreme vertigo, loss of balance and yes, vomiting to the room's inhabitants. The idea is that hostiles can be contained without using lethal force... maybe Jack Bauer from 24 should look into this Vomit Beam!
