Here’s a quote:
Wow! Through the walls? That even beats the Active Denial System — the pain ray that Noah wrote about the other day. Invocon even touts its device as a “Star Trek hand-held Phaser Weapon set on ‘Stun’.”
However, rather than causing intense pain, like the Active Denial System, Invocon is advertising a weapon that boasts the ability to go through walls and incapacitate everyone in a room by making them loose their balance. “Second order effects would be extreme motion sickness,” the company notes.
Basically, you’re safely in your house, an invisible beam hits you, you feel dizzy, and fall over (or puke). Or so goes the promotion.
