This video is actually a
three-in-one aerogel feature. Aerogel is a wispy, translucent, highly
insulating material often described as “solid smoke.” It’s worth noting
that aerogel is not a new material and may date back to the 1930s. Many
new applications and lower-cost production processes, however, are
opening up.

The first part is part of the video is a KQED/Discovery Channel
short with the basics on aerogels. The second focuses on some of the
applications for the material, including flexible insulating blankets,
from Aspen Aerogels. The final part of the video focuses on an offshoot of aerogel – SEAgel – that is an even lighter material and made from agar.
