While we wait for the final results from the European Parliament and local government elections here is the coolest thing you’ll see this weekend. The American astrophysicist Neil deGrasse Tyson introduces Adam Savage, YouTube maker, and Chuck Nice, stand up comic and radio host, to Aerogel, the porous ultralight material in which the liquid component has been replaced with a gas leaving a low density solid.
Are you aware of the reasons why Tyson’s season 2 of Cosmos did not premiere in March?
Unfortunately, yep 😦
Yeah, it’s a bummer in an “et tu Brute” sense.
You know I’be heard a fair amount about researching aerogels that can contain hydrogen gas. Not as an energy storage system but more as a way of making hydrogen filled airships safe. Helium is scarce and hydrogen flammable. While the whole Hidenburg thing was overblown (Zeppelin s still had a good safety record and it might have been sabotage.) but the image stuck with people.
Airships really are and extremely energy efficient way to haul things and travel-competitive with train by some estimates.
