I'm not sure if this is possible. Earlier last century, people thought that it was impossible to transfer images through empty space and see them. Well, humans have amazingly arrived at this stage. We can now transfer images through wireless networks to computers, or mobile signals to cell phones. It really seems rather amazing.
Therefore, I was thinking maybe one interesting possibility is to transfer the scent of a certain aroma from one place to another. Granted, humans do have many more smell receptors in their noses, so transmitting smell may be much more complicated than transmission of visual images or of sound. Still, I thought it was an interesting idea to consider.
