The Boeing created the lightest metal in the world, consisting of 99,99% air. The micro foil Shaver is an open cell polymer with three-dimensional structure, and can be compared to the structure of human bones. In our body, the outer part of the bone is very hard, but the Interior is essentially hollow with a non-compact cell structure. And this happens so the bones do not break and be lightweight.

The micro foil Shaver is one of the most durable and lightweight materials that currently exist. Could be used on an aircraft in order to reduce its weight and thus gets better fuel economy.
