Alien Tech
Styrofoam: amazing as an insulator, weighs next to nothing. the poor man's AeroGel Fiber optics: okay can you say infinite bandwidth? Microwave: do i need to explain why this is alien technology? Space blanket: almost 100% reflects thermal radiation? Crystal radio: c'mon folks, you KNOW there's a crystal in there, so WHY do you insist that crystals are "new age"? it's actually technology okay?? Tesla coil: you need to learn about this yourself, OBVIOUSLY ahead of it's time
