What is Aerogel?
is made from Silicon Dioxide, the same material as ordinary Glass,
times less dense.
Aerogel (also called 'frozen smoke' because of its hazy blue appearance), is
a truly remarkable material.
It is the lightest and lowest-density solid known to exist, and holds an
unbelievable 15 entries
in the Guinness Book of World
Records, including best insulator and
lowest density solid.
Aerogel is composed of 99.8% air and is chemically similar to ordinary
Being the world's
lightest known solid, it weighs only three times that of air.
When handled, Aerogel feels like a very light, hard foam. Being
chemically similar to glass, it also happens to shatter like glass, yet
is incredibly strong structurally, and can support thousands of times
its own weight. Theoretically,
a block weighing less than a pound could support a weight of half a ton.
Due to its microstructure, Aerogel is a powerful desiccant, rapidly
absorbing any moisture in your fingertips when held. This usually leaves
some dry spots on the skin that disappear in a short time.
Aerogel's true strength is its incredible insulating properties.
It negates just about any kind of
energy transfer - thermal, electrical or acoustic.
A one-inch thick Aerogel
window has the same insulation value as 15 panes of glass and trapped
air - which means a conventional window would have to be ten-inches
thick to equal a one-inch thick Aerogel window.
large panel of Aerogel was most recently used by NASA in the Stardust
mission, which successfully collected collect comet & interstellar
dust samples & returned them to Earth. Previously, it was used in
the Mars Pathfinder Rover to insulate its components from the large
temperature swings on Mars.

limited quantities of
Monolithic Aerogel in small disks (see below). This is the only
