  Its a waterbased water proofing agent, thus can be recycled. there are several ways to make cardboard waterproof but a most of them damage the recyclable properties of card board. The solution used is water based and doesnt do the same.
  At the same time, the helmet is about safety first and Recyclability later.
  
  As far as cardboard on the head is concerned, at present there are foam pads present which clip onto the inner surface of the ribs. Currently a more suitable inner liner is being developed as well. Its a small issue which can be easily solved.

  everyone's worrying about the sweat and rain when the bloody article says he's soaking the cardboard in plastic....
  Also carlton is right... if the cardboard edges weren't normal to the shell, then by shifting and buckling the shockwave would be slowed down... think ><><>< instead of ||||||

  Think about when it start to rain and you are wearing such a piece of cardboard helmet. You can't make sure you keeping out the corrugated cardboard from the water perfectly can you? Once the water soak into the cardboard it's gonna be as soft as waffles.It reminds me some sophomore stage works.

  A friend of mine at Brunel University undertook a similar final year project.

  Correct me if I'm wrong, but the moment you 'impregnate the cardboard grid with an acrylic waterproofing agent,' it ceases to be recyclable by conventional means.

  has he tested its safety properly?
  it looks massively dangerous. how the cardboard would absorb the power from outside?

  wont work. using the edge of cardboard is like wood. it'll just direct all pressure to your head. it has no absorption like foam. whats needed is dampening. I'm not saying you cant use cardboard, but just the current design will not do much for you if not make it worse

  You're right, my video isn't very informative. It was a two minute quickie sent from my iPhone, but I then backed it up with the BikeBiz story.
  
  The guy is getting a lot of stick for the helmet (it'll go soggy in the rain; the cardboard will hurt my head etc etc) but I think it's a fabulous concept. Those fixie riders into helmets will like these lids.
