Nonlethal Gun Makes You Wish You Were Shot with BFG - Gizmodo
"The ADS shoots a beam of high intensity millimeter waves, which in
plain English means if you get in the beam's way, it'll feel like
you're being dipped in lava. In fact, the pain is so intense, that the
longest any human test subject could withstand the beam was 5 seconds,
and a very small number of them walked away with redness and blisters
from the beam's intense heat."
