Who needs a smartphone when you can send a text message with vodka and a fan? At least, that was the question I was left with after reading about a recent project from researchers at York University. It’s not too different from smoke signals, but it’s not entirely different from drunk texting either, albeit a bit more scientific.
For the experiment, the team encoded the alphabet in evaporated alcohol which was shot across the room using a fan, then decoded using a receiver.
It’s a form of molecular communication – the same kind of system that plants and animals might use. Mastering this kind of atypical analog tool for robots who can possibly use this signaling system to understand drunkards.
