Scientists seem to have a lot of time on their hands if this is anything to go by, but hey ho, if you quite liked the idea of world domination while using a death ray, then this article is for you.
A single laser pointer is not anywhere near powerful enough to inflict a nasty end on one’s enemies due to having a power rating of 5-milliwatts. According to James Kakalios who is a physics professor at the University of Minnesota and the author of “The Physics of Superheroes”, what a job that is, makes the point that it’s in reality quite tough to kill a human being with lasers. But he did have a go at explaining it by stating that the most effective way to use a laser on a human is to “target the eye and thus melting the brain”, blimey, he must be fun at dinner parties.
So, how many lasers would you need? Well, according to Rebecca Thompson of the America Physical Society, you would need a laser at approximately 1KW, this equates to around 200,000 laser pointers. You would also need each laser pointer to focus through a lens on one spot with the aim of concentrating enough power. Every laser beam would also need to be in a “semi-circle with a radius of about 5.5”, so in theory you could buy 200,000 “laser pointers before mounting them on a Sphere with a radius of 5, 5 and aim them all through a lens.”
So yes, there you go, now you can in theory build your own death ray, well sort of, (quick disclaimer, eTeknix would advise that no one attempted to build their own death ray, we do want readers that are not melted.)
On a side note, below is a video that shows this concept being conveyed at an insane level, a Youtuber who goes by the username “styropyro” has built his own Laser shotgun which has a combined power of 40W, as you do. Guns are a problem within society, let’s hope no one decides to use laser weapons instead.
