Fusion 101: Fusion Energy Explained From Scratch

Laser fusion pioneer Dr Annie Kritcher teams up with Dr Marcius Extavour to break down fusion energy in simple terms that everyone can understand. Learn how it’s being attempted, fusion’s potential as a clean energy source, and the cutting-edge research making it possible. This episode starts at the basics - “what is an atom?” - and walks through the basic physics of what fusion energy is, and why you might care. TLDR:Firing the world’s largest ever multi-beam laser at a tiny lead can to create an x-ray oven so hot it will implode the tiny crystal of nuclear-heavy ice floating in the center of the oven, inducing a plasma in which two atoms smash together, literally become one, and spray out an astronomically large pulse of energy.
