This edition features a discussion about the hardening Army base camps from explosions and projectiles being much simpler if super materials were available to work with - say materials with 10 times the strength of steel or twice that of Kevlar. It has been known for years that materials are very strong at the molecular level. The reason why this strength doesn't exist in everyday materials is because of molecular defects and poor connections between molecules. Dr. Bob Welch discusses the work of a team of researchers at the U.S. Army Engineer Research and Development Center that are overcoming these obstacles by using the world's strongest molecules, carbon nanotubes, and by using super computers to help design the material's molecular bonds and arrangement. Their goal is to build sample fibers and membranes with one million pounds per square inch tensile strength. They recently achieved carbon nanotube fibers that have over 200,000 pounds per square inch strength, and they are working the rest of the problem.
