Rob, one of my favorite makers is constructing a giant solar death ray, he writes…
Oh man. I got my hands on a satellite dish, and soon I’ll have a free source of 13,000 watts of power! Longtime readers of Cockeyed.com will probably remember that I’ve tried this before. Inspired by the island episode of Rough Science, I attempted to build a solar-concentrating parabola out of mirrors. That attempt failed, and I was only able to heat water a little bit. However, my struggles inspired Louis Giersch to produce two sunlight concentrators himself, the second of which he coined “the Solar Death Ray”. The death ray used 112 mirrors to reflect 112 patches of sunlight onto one spot. Louis did a terrific job of showcasing the abilities of his solar tool, and now I would like to get in on the action.
