I don't know if he was actually involved in this project or not, but that was the one thing that made me think that this maybe wasn't 100% a scam?
Anyway, the implication they make in their pitch isn't that it's an open laser, but that it is a laser confined to a fiberoptic wire which leaks into the hair when pressed against it. Gustavsson has published some papers on this a few years ago in which he refers to the concept as a TRASER.
Of course, if this really is such a revolutionary advance, why go to Kickstarter to bring it to market? Why not traditional investors. Gotta be easier to get funding for a significant manufacturing outlay, right? Just to not have to sell a piece of the company? To justify that there is a market?
I personally don't have the background to make any judgments about this and I definitely don't understand the article he published, but I just thought it didn't completely fail the smell test.
