Humans have a stereo sense of smell that subconsciously guides navigation. Who knew?
Today’s invention attempts to make use of this fact for explorers, soldiers or anyone navigating an unknown environment without a map.
If the explorer needed to find water or fruit or the sea or human habitation, in an emergency, they would don a pair of goggles containing two pipes: one running to each nostril from each side of the goggles.
This would provide enhanced stereo smell capability (just as artillery range finders do for stereo vision).
They would then calmly feel which direction to take and this would improve their chances of reaching safety significantly.
