"A freshly mowed lawn, lit charcoal and sunscreen are just a few summer smells that are as ephemeral as they are memorable."
Alternatively go outside , mow the lawn ,then start a BBQ and slap on some sunscreen - i suspect that will be cheaper and more readily available.
These smells hardly require complex analysis in order to recreate them . We can do that just fine.
It would perhaps be more useful if this device could be put to use for example to capture the smells of fruits, or flowers that are rare or on the brink of
extinction.This would perhaps be good to draw attention to some of the issues surrounding looking after out planet. And also that our childrens children could
learn and enjoy the odours of our forefathers.
