A water-saving shower head.
Nebia, Inc.

The Nebia showerhead was five years in design and development and employed aerospace engineering for its microatomizing technology. The showerhead produces hundreds or more droplets dispersed over five times the area of a regular shower. It is thirteen times more thermally efficient (the heat you feel on your body) and reduces water use by 70 percent compared to conventional showerheads and by 60 percent compared to the United States Environmental Protection Agency’s WaterSense showerheads.
