I’ve never heard about this material but apparently its been around since 1930’s.

Primarily something used by NASA this material has been receiving more funding and under going more research. Wonder when we’ll see this stuff being used commercially! Can you imagine cars being made of this stuff! Read more here (via: Gizmag)
