PK4A is a 20-foot flamethrower controlled by a wireless EEG headset. EEG as in brain scanning. As in, this thing fires on mental commands. The entire project was built from the ground up to be a real-life method of achieving pyrokinesis, only with science instead of mutant powers and/or wizardry. The results look something like this:
"You're right -- the middle of the woods seems like the perfect place to test this project."
Keep in mind that this is all just a demonstration of the potential for a system like this. The creators have made it a point to make it completely customizable. In the video, it has a dead man's switch and fires straight up in the air, but those were just safety precautions. It's only a matter of time before someone takes this technology, modifies it into a shoulder-mounted device and uses it to take over a small city.
