This is interesting. The photonic disruptors on the sunk anti-whaling vessel, the Andy Gil, discussed previously here, sent out a green beam. These disruptors are meant to cause temporary blindness.
Here’s a screenshot from a video put up by the Institute of Cetacean Research (aka the Japanese whaling fleet), which links to the video.
It seems ironic that these beams are green. Are these devices cool? I mean, they’re for military use, as I understand it, possibly crossing the line from passive resistance to using weaponry.
