A bicycle helmet made out of this material sounds perfect to me. Good protection, light weight, and great ventilation.

  Doesn't seem a good protection against your head hitting a sharp edge - due to its elasticity.

    Well you'd still pair it with a shell.

      Even so, I don't see how this could replace the foam in a conventional helmet. It seems like it has its strength in its elasticity, but not much else. The video did a poor job at explaining good applications.
