Melting, Burning, and Generally Obliterating Stuff with the Power of the Sun

I always find that I discover cool stuff when I am teaching about it – right now, for example, I’m lecturing to my introductory Stage Lighting classes about reflection, refraction, the Index of Refraction, reflectance, normal angles, and all of that kind of stuff.  I love it, I’m a nerd to the Nth degree.  I’m also lucky that my research karma is good!

Something I find quite sexy is capturing solar rays for the purpose of just destroying stuff in a non-military way.  Yes, I’m one of those campers who loves campfires for the sheer awesome power of them.  I came across a few videos of people harnessing the awesome power of our Sun into a small few centimeter-square area for the purposes of, well, burning stuff.  I have two examples – one is an expensive solar capture device that focuses a few square meters of sun into an area of an inch, and the other is a homemade solar reflector made from a satellite dish.  Even though the cheaper one is cheaply made (I mean comparatively, not offensively), it harnesses some amazing solar power!

Check out this first video – a lab environment, a huge mirror, and thousands of degrees of sunlight:

Here’s the second video, a homemade SOLAR DEATH RAY!

Awesome.

Thanks Hack-N-Mod!
