Last Show Recap

Nanomaterials

Melvin Dummar says a grand conspiracy has denied him his portion of billionaire Howard Hughes' vast estate. Many consider Dummar to be a fraud but an in-depth investigation by Gary Magnesen has apparently shown Dummar to be a good samaritan who saved Hughes from certain death. Both joined George Knapp to discuss why Hughes was in the desert, as well as those who schemed to deny Dummar and several institutions of their rightful share of the Hughes estate. In the first hour, veteran music journalist Joel Selvin talked about the notorious Rolling Stones Altamont concert of 1969, considered by many to be rock’s darkest day.

Nanomaterials

Show Archive
Date: Saturday - July 24, 2004
Host: Art Bell
Guests: Bart Kosko

Professor of electrical engineering, Bart Kosko discussed the latest research and technology that could improve protective body armor, as well as other products, by utilizing new nanomaterials.

Kosko said nano-weaves (created from nanotubes) could be used to enhance body armor. He pointed out that current body armor cannot stop high-powered rifle bullets, and even when the armor prevents a bullet from penetrating, the damage sustained by a human wearing it can often be fatal. Kosko equated being shot by a .45 caliber bullet while wearing body armor to getting hit with a baseball at 90 MPH on an unprotected chest. He indicated that "smart" nanofiber body armor would one day be able to adapt to conditions placed on it and adjust accordingly to protect its wearer.

Kosko also talked about potential "super acids" that could be programmed for the selective destruction of matter, dissolving one part of an object while leaving other parts unaffected. When asked about fear of runaway nanobots, or "gray goo," Kosko said the scenario is "a little far-fetched" mainly because the required chain reaction would be difficult to initiate and sustain.
