Description

Homemade DIY solar parabolic death ray mirror for solar cooking. This is similar to the parabolic heat cooker I made a few years ago.

This construction is much easier and the thinner mylar allows for a much more accurate image of the sun producing amazing bulk temperatures. A stand and Heliostat is optional. I can cook off axis with for or five manual adjustments during a cooking cycle. The longer focal length allows for arrays of up to 25 mirrors at 30 feet.

Solar death rays are a term used for parabolic shapes that can redirect sunlight over a longer distance allowing for target illumination. Solar parabolic hacks from mylar blankets are an excellent low cost option for solar parabolic power.
