The Guardian: Bike lock developed that makes thieves immediately vomit

He eventually landed on a less violent and more legal innovation. “I realized there really is no solution to this problem,” he said. “The biggest problem in this industry is that people don’t know that the lock that they bought for $20 is absolutely worthless. It costs at least $100 to have at least somewhere close to where you can at least curb the chances of a thief wanting to steal your bike.”

With the right tools, Idzkowski said, a thief could cut through most locks in less than a minute. Thieves, he said, “talk in seconds: a 15-second bike, a 20-second bike, and it goes up to 30-60-second bikes, with Kryptonite locks that require two cuts, each about 25 seconds”.

With his co-inventor, Yves Perrenoud, Idzkowski created a U-shaped lock of carbon and steel with a hollow chamber to hold one of three pressurized gases of their own concoction, including one called “formula D_1”. When someone cuts about 30% of the way into the lock, Idzkowski said, the gas erupts in the direction of the gash.
