How would you like to pop up vodka or any carbonated/alcoholic drink to send a text message? In any case, how practical would that be? If practical, how useful?
“Imagine sending a detailed message using perfume”, those are the words of Dr. Weisi Guo of the University of Warwick in the UK in a press release about this O Canada message that a team of researchers from Warwick and York University in Toronto were able to send by popping up vodka.
The team first coded the message into a string of 1s and 0s, then programmed their vodka pop up to be “single spray = 1” and “no spray = 0”. With this the team were able to pop up O Canada over several meters.
OK so the team were able to spray O’ Canada, how can this help anyone? CNET writes, “chemical signals could prove more practical and efficient in certain scenarios. In nanomedicine, for instance, scientists are injecting mini robots and sensors to perform specific tasks, but when relying on electromagnetic signals, they run up against the issue of antenna size, which would be moot here. Chemicals could also monitor hard-to-reach systems and help prevent events like the Deepwater Horizon oil spill of 2010 or the bus-size group of fat cells that clogged the London sewage networks earlier this year.”
Let scientists do what they gotta do. Personally I do not think that molecular communication will ever achieve any significant large scale practical use.
