The video shows the helmet being dropped on an anvil, I know this is an industry standard impact test for helmets, but unlike tests and wood peckers a cyclist's head may encounter a hard object from a bias trajectory.
There seems to be an effort to green wash the helmet. While the shock absorbing material is re-purposed cardboard the outer shell and probably the liner are synthetic. I also heard the statement 'without electricity' but there was surely electricity used to manufacture the cardboard and I suspect that lazer cutter used to cut the ribs requires electricity as well.
I would like to see a helmet that tackles ventilation with out sacrificing penetration resistance, and I would like to see more life like crash tests, like launching a helemt clad dummy out of a cannon.
