The sun is totally, like, hot, you know? And if you get enough bits of sunlight together in the same spot, you can do some pretty spectacular things with the resulting 2,400 degrees (Fahrenheit, I assume) of heat. Like melting a tidy little hole through a solid steel plate in mere seconds. If they’d just hook up a Stirling Engine to this thing, our energy problems would be solved. And if not, well… It’d make a pretty badass death ray.
