Your city can save millions of dollars a year by employing this one weird animal!

Background:

Modern buildings with large windows generally do not provide any way of opening the windows. This means that window washers are required and, additionally, that the window washers must work from the exterior of the building.

Fig 1: Window washing is a hazardous dangerous occupation that can be streamlined by making use of an ecologically-friendly natural and organic cage-free solution that already exists—the humble snail.

Proposal:

Specifically, we can use a terrestrial variant of the common aquarium snail to clean all the dirt and grime off a building.

All we need to do is:

  • Find a type of snail that can climb up glass (easy) and is air-breathing (easy)
  • Find a food source for this snail that will motivate it to climb all around the glass
  • Coat our skyscraper / other building with this substance. For example, if the snail likes to eat honey, then we would pour honey off the roof of the building until the skyscraper was covered in it (as the honey slowly drips down the building).

  • Finally, unleash the cleaning snails to clean off both the honey and any assorted window grime.

Conclusion:

This is an eco-friendly way of washing windows that does not use any harsh chemicals.

PROS: Reduces snail unemployment.

CONS: Increases human unemployment.
