Editing Aerogels and the Architecture of the Void (section)

* '''The Mars Spacesuit Paradox''' — A human on Mars requires massive thermal insulation. A one-inch thick layer of aerogel would make an astronaut impervious to extreme heat or extreme cold. Why don't spacesuits use it? Because humans bend their elbows. Silica aerogel is rigid glass. If an astronaut bends their arm, the aerogel snaps and turns to dust, pooling in the bottom of the sleeve, completely destroying the thermal barrier. The massive, multi-million dollar engineering challenge in the textile industry is "Aerogel Blankets"—taking the fragile silica dust and weaving it into flexible fiberglass or Kevlar matrices, attempting to give the rigid glass the flexibility of a winter coat.
* '''The Optical Window Dream''' — Traditional double-pane glass windows are the worst thermal leak in a modern house. They bleed massive amounts of expensive heating and air conditioning. Because silica aerogel is optically translucent (Solid Smoke), architects desperately want to inject aerogel between the panes of window glass. It would give a clear window the thermal insulation value of a massive, thick brick wall. The problem is the "ghostly blue tint." The nano-pores of the aerogel scatter blue light (Rayleigh Scattering, exactly the same physics that makes the sky blue). Until chemists can perfectly eliminate the blue haze, making it 100% transparent, consumers will refuse to put blue-tinted, blurry windows in their homes.
