How To Make Solar Concentrating Mirrors (super HOT focal point)

In this video I show how to convert inexpensive truck mirrors into powerful first surface solar concentrators. Check out my sponsor Brilliant for a really fun way to learn! First surface mirrors are an extremely efficient way of concentrating solar energy, much more efficient for their size than a fresnel lens. This type of mirror is also essential for optical applications. Check out the video about making first surface mirrors over on GreenPowerScience: Thanks to all my Patrons for helping me make these videos! A special thanks to my top Patrons: Syniurge, Matthew Leitzke, TheBackyardScientist, Enzo Breda Lee, John Johnson, & Thibaud Peverelli! Thanks for watching!
