Cardboard bike helmet could revolutionize head safety

Don't Sweat The Technique. hopefully waterproof from inside!

Modern bike helmets channel air over the top of your head. It is actually cooler to wear the helmet than not, as long as your moving. This helmet looks hot. Perhaps they can produce a new design to address this issue.

My spouse is an avid biker; we live in Vienna. My spouse takes her bike to work, where she is a researcher and medical doctor, at the university. I admire her commitment to a greener world - but, I remain concerned for her welfare while riding.

Cars are not necessarily prepared for bicyclists, even though we do have bike paths. We are not quite there yet, in Vienna.

One of the greatest places I have been that protects bicyclists is in Holland, for me, specifically Amsterdam.

This leads me to you, Anirudha Surabhi: I am constantly looking for a better helmet and I love your thinking and ingenuity. I also found your correlation of the woodpecker's design, very interesting.

I wanted to simply say thank you. Bicycle helmets saves lives.

Awesome invention, brilliant use of science! Congratulations, I will buy it!

ver interesting technology for sure.... however... to be succesful in that market... the helmet also must cool the head as mentioned before... maybe it does... it just doesn't look like it.

I'll bet a design using two shells, one flush with the head and one on the exterior with the space in between simply stuffed with crumpled paper would have similar characteristics. The neat thing about paper crumples is that they give, but they offer more resistance the more they are crumpled. The crumpled material need not be paper, but it serves as an obvious model.

Seems like a brilliant idea as long as it doesn't disintegrate when moist through sweat or rain (we seem to get a lot of that here in England).

One good thing for this design is that it will make custom fitting of oversized heads (like mine) a cinch, just send a measurement of your noggin and the laser will cut it out perfectly.

Great Invention. I love that the wood pecker was a guide.

What happens to the helmet after an impact? Does the 'cardboard" structure need to be replaced? Do you throw away the entire helmet?

Glad to see the waterproofing issue was addressed (5:35 in the video), that was my only concern.

This looks like a great design. I think you should look into developing this product for Soccer Players and American Football. Concussions are becoming a great concern in contact sports now. Evidence has shown that many more concussions occur and are of greater harm than was previously believed. This product or a similar one could go a long way to helping prevent or reduce these injuries. The cardboard liner could be made for quick replacement to keep cost down on damaged helmets.

When does the motorcycle version come out?

Superb demonstration Anirudha. Hope to see the helmets on the market really soon. Congratulations on a well thought out product d'-)

Stronger. Safer. Lighter. Greener.

Really good.
