Ethan Siegel Weekend Diversion: Be Safe, Be Free! has this story on his Starts With a Bang blog. An air bag safety helmet. You just strap it around your neck and when you have an accident it inflates around your head. It meets the EU requirements for a safety helmet. Right now it costs about $600 US, but hopefully the price will come down.



I am particularly interested because I took up bicycle riding a couple of months ago and the helmet really isn't that much fun.
