Check out my sponsor Brilliant for a really fun way to learn! https://www.Brilliant.org/NightHawk 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: https://youtu.be/IaEaaeajCSI 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! https://www.patreon.com/NightHawkProjects Thanks for watching!
