Wasabi-Based Odor Alarm

A wasabi-based fire alarm is under development at Japan's Shiga University of Medical Science. The heart of the device is a set of spray cans filled with essence of wasabi horseradish.

The device worked on 13 out of 14 test subjects. The intent is that this device could be used for a fire alarm for people who are unable to hear.

The developers of the wasabi fire alarm should take a look at the research that doomed the Hakugen Odor Alarm Clock; take a look at Sad Day For Odor Alarm Clock Enthusiasts for more information.

Frank Herbert writes about the odalarm, an alarm clock that uses scent rather than sound, in his 1977 novel The Dosadi Experiment

The odalarm awoke Jorj X. McKie with a whiff of lemon.
