The Amazing Properties of Aerogel
RideMax writes "We all know NASA is using a substance called 'aerogel' in the Stardust spacecraft to catch pieces of the Wild-2 comet. The NYT is running an article about some other amazing aerogel properties. My favorite quote: 'It's the lowest density of any solid, and it has the highest thermoinsulation properties. Though it would be very expensive, you could take a two- or three-bedroom house, insulate it with aerogel, and you could heat the house with a candle. But eventually the house would become too hot.'" We've looked at Aerogel before.

Whoops forgot to post link! Damn, now I lost link. Arg... Anyway, here's a good book on aerogel.
Great book, I read it 4 times and love for it to reference inside!!!

if you have the smallest crack in your house, then air will be allowed to escape. this means that you do not have a closed system. assuming that air is an ideal (or even a van der Waals) gas, if it heats up, it expands. this means that air escapes and the temperature sinks. hence you would NOT heat up your house with a candle. just think of the equation pV = NRT, i.e. T ~ 1/N (temperature proportional to 1/number of particles).
as a matter of fact, when you heat up a house, the air is not what keeps it hot. it is the items, such as walls, and stuff, which irradiate the heat off and so warm the room. if you now make walls out of a completeley nonheatconducting stuff, would it still work? i am not sure...
we all know NASA has a huge penis, why are we not worshipping it?
It can be used as a dessert topping and floor polish.
To keep this vaguely on topic, I'll bet FedEx would hate me if I tried to ship several cubic meters of this stuff, since they charge by weight.

We all know it's you, Michael Sims. You're allowed to log in to post this.
No it wasn't.
It's clear to anyone who has bothered to read the article, and more importantly looked at the accompanying pictures, that this so-called "Aerogel"is nothing more than a hastily contrived liberal smokescreen. I've seen more convincing effects on Blake's Seven.
Aerogel doesn't exist. Aerogel has never existed. Aerogel, with its many wacky and ill thought out supposed properties, breaks the law of thermodynamics as we scientists understand them today. Why has this "Hot Aerogel" been created by liberals for widespread news dissemination?
Well, I might sound paranoid, but there was a little thing called "The State of the Union" speech last night, where King Bush outlined his masterplan to continue making America kick-ass on all frontiers. The liberals know that watching The Man lay it out is going to convince anyone to vote for him. Hell, even reading the speech is going to make the most die hard committed liberal start destroying condoms and bombing abortionists, that's how good it was. So this Aerogel suddenly appears - Whoa: control the front page.
And you guys fell for it. Pathetic.
