In this episode, I interview Dr. Brett Yurash as we discuss the latest advancements in solar energy, how light works, and the wonderful world of semiconductors. "We're talking solar panels that you can print out on reams of paper. You could make them transparent and line every window or surface on a skyscraper to power cities." -Dr. Yurash

How does a smart phone or the internet work? What is light and how can we use it to power cities? What does LED even stand for anyway? 

Find the answers to these questions and more all on this episode of Goggles Off.
