Talk:Aerogel

I vaguely recall reading a book decades ago describing a tribe of people who had vacuum filled airships (Tom Swift series possibly). I think (or dreamed) I read somewhere that a helium filled aerogel was made to float. What if one were to take a big (read expensive) block of aerogel and vacuum bag it. Could it just possibly work like a mythical vacuum balloon without having a impossibly light and strong pressure vessel by supporting a thin pressure envelope from the inside? Has this experiment been tried? I see it is a recurring theme Vacuum airship - Idyllic press (talk) 21:59, 28 November 2014 (UTC) Reply

• Corrected formatting/usage for http://www.llnl.gov/IPandC/technology/profile/aerogel/Terms/index.php
• Corrected formatting/usage for http://solar.gatech.edu/light_roof.php
• Added archive https://web.archive.org/web/20070817195536/http://www.msnbc.msn.com:80/id/20123389/site/newsweek/ to http://www.msnbc.msn.com/id/20123389/site/newsweek/

I'm surprised it was unnoticed: "The density of air is 1,200 g/m3 ..." the value is obviously bad, so i looked up the citation to see whether the citation itself had an error. Nope, it's either the uploader couldn't read the table (which clearly gave all densities in g/cm3, not g/m3), or someone trolled the wikepedia by change all the units.

The density of Aerogel itself that was stated to be as low as "1.000 g/m3" should put up a bs alarm right away - i checked the cited source once again - it stated none of the things said in the article. It did mention that they measured dielectric constant, which was 1.008 , but it was not a density. It is funny though... the numbers still don't match - i guess it was too hard to copy that down.

This article needs to be fixed and checked for errors by someone who actually understands, what they're reading and writing about. Ok, the thing is that the history of changes made by the person, who screwed this stuff up, should be checked for more errors in other articles in order to ensure that there is no more false information.

These aren't all of errors that i noticed this article - i didn't read the whole article, i just skimmed by. I left the mistakes be. — Preceding unsigned comment added by Nordzikas (talk • contribs) 21:01, 21 March 2017 (UTC) Reply

Aerogels are called both hygroscopic and hydrophilic in the article. Can't be both. --84.189.83.112 (talk) 12:34, 25 November 2020 (UTC) Reply
