The Tiny Solutions to Our Big Energy Problem program gives a brief overview of energy sources and our current energy crisis and discusses a variety of ways that nanotechnology can improve the way we harness energy (improving solar cells), distribute energy (carbon nanotube transmission lines) and use energy (nanotech-enhanced LED bulbs). It is primarily a slideshow presentation, designed for medium-to-large audiences. It consists mostly of a lecture, with a few live demonstrations and a few audience interactions.
Graphene. If you haven't heard of it before, you have now. And it may prove to be the next big thing in materials science. SciShow explains what it is, why it's so awesome, and what challenges we face in harnessing its amazing properties. (5 minutes) Hosted by Hank Green, SciShow discusses science news and history and concepts. With equal parts skepticism and enthusiasm, we go a little deeper...without going off the deep end.
