Non-fogging glass may have use in scuba gear

Scientists at the Massachusetts Institute of Technology (MIT) have discovered a simple process that produces glass that is less smooth. Significantly less smooth.

This new process focuses on producing an entire layer of glass that is very porous with many small holes. Each hole is around 1,000 times smaller than the diameter of a human hair. How does this relate to scuba diving?...

When condensation forms on this special glass, rather than creating droplets on the glass, it gets drawn into the tiny pores of the glass surface. This allows it to bond with other water molecules. When this process occurs the water, although remaining on the glass, is very evenly distributed allowing one to see through it much like peering through a glass of water. This coating is permanent, unlike some of the present solutions available.

This new non-fogging glass may set a standard for use in a variety of inductries including scuba diving where foggy masks can be a problem. The technology may become standard in various products, including scuba diving masks an area in which fogging can produce problems. The researchers hope to see the use of their technology in products offered over the next several years. For the full story visit: Non-Fogging Glass
