Honk If There’s A Natural Disaster"
Few things are more annoying than an endlessly honking horn. German scientists think that maddening sound is a great way to warn people of impending disasters.
The guys at the Fraunhofer Institute for Technological Trend Analysis are working on a way to use automobile horns to, in effect, crowdsource the network of emergency warning sirens that used to cover Germany. Such a system would cost next to nothing to adopt, they say, and could be introduced as early as next year.
