World's Lightest Solid!

271 834 Zhliadnutia 28 mil.

Aerogels are the world's lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest.
At one point Dr. Steven Jones literally held the Guinness World Record for making the lightest aerogel and therefore lightest solid. If you're interested in learning more about aerogels, let me know in the comments as there is a potential trilogy in the works...
Huge thanks to Dr. Stephen Steiner and the crew at Aerogel Technologies. To find out more or buy your own aerogel sample, check out:
Thanks to Dr. Steven Jones and Dr. Mihail Petkov at NASA's Jet Propulsion Laboratory
And thanks to FLIR for loaning us the awesome high definition thermal camera. The footage is amazing!

    WHY are we NOT using this on an industrial scale??? I mean, SHITE!!! We TALK about "green" this and "green" that... THIS used for insulation!?! There ARE no words to describe. We could have ALMOST a 95%+- insulated homes and buildings. The ONLY BTU's that would need to be added (or MOSTLY) removed, would be that of the people and appliances in the structure. Hell, even if it was "fractured" in the walls, floors, ceilings... it would STILL work remarkably well... ...Just ANOTHER form of "technology" that UNFORTUNATELY, "we" will NOT be seen on the "consumer" market. Yet we give freaking NASA $56 MILLION USD/DAY!!! What a WASTE!!! ...anyway, just my opinions and observations. Nothing more, Nothing less. : ) -EB
