okay fine... this is what he actually said.
“So, supposing we hit the body with a tremendous — whether it’s ultraviolet or just very powerful light — and I think you said that that hasn’t been checked, but you’re going to test it. And then I said, supposing you brought the light inside the body, which you can do either through the skin or in some other way, and I think you said you’re going to test that, too. It sounds interesting. And then I see the disinfectant, where it knocks it out in a minute. One minute. And is there a way we can do something like that, by injection inside or almost a cleaning.
Yes, "hit[ing] the body wiht a tremendous ... light... through the skin" is basically just giving people skin cancer. and you can't "bring light inside the body." It might be the most idiotic thing I've heard, he speaks like he hasn't done basic physics. and he suggested injecting a disinfectant into your body. He obviously hasn't done basic anatomy courses either.
