... shouldn't be used in the automotive industry? What about construction? Watches? Phones? Computers? Etc. If aerogel is really the "world's lightest solid" and 4000 times stronger than its own weight, would it not make sense for it to be used in cars to replace any of the following compositions: carbon fiber/fiber glass/plastic/metal? If YOUTEK (d3o) siffens upon impact, would it not be useful to place some of this material collision-prone areas of a vehicle? Not even in the most expensive cars are they used (that I know of). Could you guys think of any more uses for these "futuristic materials"? It almost seems ******** to me if all of this material is so powerful, strong, light as they claim be, why isn't it being used elsewhere? This has been on my mind for quite some time... What do you guys think? Has tennis racquet technology ever crossed industries? I've personally never heard of it.
