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! 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.
