Hi Meg Of Buffalo - not sure if the subject is still open(typing this on Sept 8th), but you are absolutely right of course, language does evolve and the English I try to speak and write (badly!) is so different from that of centuries ago. The point I was trying to make,albeit not very well, was that we are readin g an English newspaper here and I don't think it is right for other English speakers be they American or Australian etc to criticise the language or words written. An example is that following the awful bridge collapse in the Mid-West (sorry I can't recall the name of the place) an American reader said that we don't have lorries in the States, they are called trucks. Most of us Brits know that! We've all seen enough American films, but the guy in question was reading an English paper. So lorry is the correct word. This all sounds so serious but isn' t great fun really - by the way I think you are wrong about the apostrophe. I'll check with my American teacher brother-in-law.

Brian Wildey, Fleurance, France

Has anyone looked at how the stuff breaks down int he environment when it's not in use? Is its afterlife eco-friendly or is it another catastrophe like plastic waiting to happen?

va, toronto,

Why isn't the military using aerogel to insulate the Humvees as protection against bomb blasts (IEDs) in Iraq and Afganistan? Wouldn't that be less expensive than armour plate, etc? And why aren't we seeing this stuff used to clean up oil spills and chemical waste in our rivers, streams and oceans? These people talk and talk about cleaning up the planet and green this and green that. Well, seems like this is the stuff to do it all. So get with it already! I guess the" powers that be" are trying to figure out how they can make the usual killing off of it. What a shame because it could be saving lives and saving our planet's resources in so many ways. Where's Al Gore and his ilk when we really need them?

Sam, San Antonio, TX

NASA, since you have it, use it. Coat the insolation on the fuel tank to keep it from falling of, or coat the underside of the space shuttle with it to absorbe the shock of foam from the fuel tank. Either way, problem solved till we get a new space vehicle. Sometimes the answer is right under your nose. Now use it on the nose of the shuttle.

John Weaver, TItusville, USA

Tairaa, you fail.

Jeeum, Charlotte, NC

Please tell Congress about this. If we could all insulate our homes with this, we sould solve the energy problem.

Irene, Davenport, Florida

I wrote to Aspen Aerogel and priced the flexible sheets at $5 a square foot. This makes it very reasonable for small applications (e.g. a sleeping bag or coat) but very expensive for insulating a house. Still, I bet prices will come down with ramping up of production.

erik ray, boston, massachusetts

"By nature wouldn't a vacuum be the best insulator."

Yes, if you want to be extremely cold. Temperature cannot exist without substance, it isn't a freestanding radical by any means.
So, the closest you can get to absolute zero (-273ºC or 0ºK) in nature is by way of a vacuum.

Tairaa, Victoria, Canada/British Columbia

I can't believe many of the comments I have just read-above. Aerogels are made with ~ 99.5% silica, SiO2, SAND! Will it pollute? Why isn't it on our tanks yet? Why does it cost so much? Etc, etc. Cutting edge technology means exactly that. It is in it's infantcy. Consider how man years it took to fully develope nylon, teflon, velcro,cell phones, computer products and many other items that are commonly used today. The above comments are exactly the reason science needs to be a mandatory subject in every childs education. All the way through college! A new material is synthecized in a chemical laboratory. Enginners design, develope and manufacture products using that technology and move it to market. Any wonder why we need scentists and engineers in America?

Ed Kowalski, Cherry Run, WV, U.S.A

To Brian Wildey- first off, you've forgotten your apostrophe, speaking of correct english. It is "change for change's sake". Secondly, It is ridiculous to sit about and criticize other english-speaking countries for somehow having "butchered" english, when within England there are so many dialects. I might as well accuse the English of having butchered Anglo-saxon. Languages change and alter over time. This has been happening since they were first developed. No one in America sat around and said, "Alright, everyone, let's change the dialect, here you go." It wasn't deliberate. It just happens. How do you think French arose out of Latin? Or do the french speak a differrent language just to be non-conformist?

Meg, Buffalo, New York

Please, give us some idea of its cost. I hate articles that speak of exciting products without some idea if we will ever be able to buy it in our lifetime.

Bob Heideman, Apopka, Fl

This is not NEWS.

Isn't all this stuff like calculus you have some limit or unity and as you find a better way(method or technique) to or as you appoach that value you get more efficient.

I believe that this stuff is great but I hate when people make general statments that are not totally true

Three methods of Heat Transfer

1. Convection
2. Conduction
3. Radiation

If I am wrong please ignore my ignorance

Ken, murrysville, pa

To Brian Wildey, I have to say-Before we begin, you've for gotten to put an apostrophe. It is change for change's sake, not changes. That would be the correct english. Now, If you look at english, even with in the UK there are so many differrent dialects, how can you possibly sit there and accuse any other english-speaking countries of somehow butchering the language?! Languages change and evolve over time, accents develop and regional terms become part of daily speech. This has been happening since the first languages developed. How do you think French came out of Latin? Should I accuse you of having butchered a language that truly only belongs to the ancient romans?!

Meg, Buffalo, New York

Finally. Smoke pants are just around the corner. And dynamite proof. Who knew?

Porterhouse, Tampa, FL

Has anyone thought about what the LONG-TERM environmental 'might' impact might be?

So many times we 'think' we've created something safe and WONDERFUL ... only to learn, over time, it's poisonous or, destructive in some other way.

If NASA has known about this for so many years, why haven't the Space Shuttles been insulated with it, instead of the foam that keeps hitting the tiles during take-off?

If it's so 'shock-proof' then why haven't our tanks and bullets been coated with this, instead of the depleted uranium presently being used; you know, the same depleted uranium that is contaminating our ground water, the animals and fish, our military fighting forces, and the sperm/ovum of the active personnel who go on to create babies - babies being born with severe birth defects (a DIRECT RESULT of exposure to depleted uranium)?

IF this product is such a miracle, let's see it proved before we herald it's desirability only to learn, years later, how much damage it's caused...

Barbara, Hollywood, CA

This stuff has so much potential that I at first thought it was some sort of joke. I'm now convinced that it not a joke. I'm sure NASA is gonna use this stuff in the new shuttle designs.

ivan, indianapolis, IN

Has anyone thought why this isn't in all homes, and clothing yet. I just tried to buy this stuff and they were quoting US$25 for a 2cm square, by 1cm thick. Hmmm.
Lets say one wall is 10m x 5m, 4 walls and a roof. Oooo how much is that going to cost now for single layer insulation. Thats about 3.2 mill for the first wall, then there's the other 3, and the roof, call it US$15-20 million for the house. But just think how much you would save in the heating billls.

Mikios, Hull, England

Keith, Fremont, California, USA

very interesting, a new material for the wolrd!
It's gonna change the world!!

galop, andolsheim, france

I've known about this stuff for years. I have a picture of a <1 inch thickness of aerogel between a blowtorch and an untouched flower. It's insulating properties are indeed amazing. What's more amazing is that it's taken this long to get the interest of various industries. I gather that once a place is set up to make it, it's really rather cheap. I understand that gelatin can also be made into an aerogel. Since they can also make it out of platinum, it looks like almost anything can be made into it, taking almost nothing of the base material, with the remainder being gas. Raw materials would be very inexpensive, then, compared to the amount of material it makes.

It seems to me that, combining a couple of manufacturing processes, they ought to be able to make a neural net with it. That would carry interesting implications for computing. I'll look forward to seeing what other uses are found for it.

Ian

Ian MacLeod, Madras, OR

My goodness - reading these comments is like watching a circus sideshow - painful and embarrassing.

No - not alien tech, not Photoshopped, no military application. Get an education, folks. This stuff has been around for a while - I first saw a sample a couple of decades ago, when I was a kid - and I was fascinated. It's pretty neat stuff. Glad to see that it has been developed into a commercial product.

Reid, Geneva, Switzerland

Depending on the base material, I wonder if they could line up the nano-sized holes such that they'd provide a framework for carbon nanotubes? The uses then would be fantastic! A flexible CPU with its own paper battery? A neural network that would fit in a button? If the tensile strength can be increased, it would indeed be a boon for the shuttle. As for clothing, if the holes in it can be controlled as to size, the insulation rating is also controllable. Otherwise, it's like wrapping yourself in plastic wrap.

Aerogel has been around for some time. It sounds like nanotech and other manufacturing techniques are now getting to where it can become a viable product. If so, the potential is fantastic, and the comment about changing the world isn't that far off. Also, people have asked about disposal: it sounds like the right solvent would do it.

BTW, to the person who said we can break the speed of light: no, we can't.

Ian MacLeod, Madras, Oregon

Lets wait and see how/if the scientific community makes use of this new material/technology and then wait again to see if the enviromentalist find a reason to put it on the endangered list and then wait again to see if the general populaiton will accept it in any form.

Phil, Pottsboro, Texas

I want aerogel in my home's walls right now. Nice idea for a startup business. It would be expensive,especialy at first,but the savings would pay for it while more aerogel suppliers deveoped.

Lil, Vandalia, OH

There was a poster that said that this could be used to shield our vehicles in Iraq to negate the effect of IUD's (sic), I'd like to know just how Intra Uterine Devices are being used to damage vehicles there. Maybe it's the excess hanky panky that takes place due to the effect of not caring about pregnancy?

One wonders.

John, San Jose, California, USA

I wonder how long it will be before we have cars and planes made out of this material. Imagine crashing into a vehicle made of this stuff...it wouldn't be a fair crash, as the non Aerogel vehicle would surely come out the loser. How wonderful that in a world such as ours, full of governments scaring it's populace with scary terrorist scenarios in order to strip away our liberties with things like the Patriot Act, and cash in on our tax money by paying war profiteering companies like Halliburton tons of money, we still have the time to develop a product like Aerogel, something that will actually help mankind, as opposed to occupying countries but falsely calling it a "war", killing and torturing hundreds of thousands of innocent people for no purpose at all.

Where do I invest. This will change the world. Take the hydrogen issue. It will speed up the creation of hydogen. Use hydrogen as fuels and the CO2 argument is OVER. We already have man in Florida that uses water to fuel his car by splitting the molecule. HE also welds with the process. A cool flame the melts steel. Hopefully this will do the trick.

Bobbypapadopolous , jacksonville , fl

This reminds me of back during the Stalin era in the old USSR when the Soviets claimed to have invented just about everything. These days its bloody NASA and the Americans making such claims. The hard work on Aerogel was done at the University of Lund in Sweden in the late 1970's and early 1980's. http://www.airglass.se/ I was there when it happened. I had a bunch of samples from the lab at the time. It is weird stuff. It's a material that you can blow off of your hand with a breath that will chip like plate class.

F Higgs, Pacific Grove, California

Isidro, you appear as tolerant as most neo-liberals. If two people from the same U.S. state are so different is it any wonder so many countries cannot get along? I have to agree with Mr. Burke here, there is a logical scientific explanation for this substances chemical properties, and it apparently took decades of refinement in a lab, and thousands of man-hours, to develop the substance in a usable form. Going from the most widely-used definition, I agree with Edmund Burke (I like the pseudonym) as he used the most popular definition. Your definition of miracle is also correct, just less popular. I feel bad that you are so hateful of how other people choose to live their lives.

As far as the non mis-statement by the homeowner who used this seemingly wonderful product, many structures are heated/cooled using outdoor temperature as the factor of how many btu's need to be generated. I would have liked to see the "r-value" though (insulating factor).

Tim, Rochester, NY, USA

Hey Richard from Lompoc USA, you don't know what you're talking about. But more importantly, this stuff sounds great. The wonder invention.

JJ, Boston, MA

As for turning the thermostat down, human comfort is heavily influenced by radiant temperature (why you can feel warm in the sun but a little cool in the shade on a spring day). Thermostats only measure air drybulb temperature. When you insulate exterior walls better their interior radiant surface temperature will be increased in the heating season. The net result is that the air temperature (thermostat setting) can be dropped and still maintain the same sensed comfort. Heating and cooling engineering is usually not about maintaining a set air temperature, but about maintaining *comfort*.

John Weale, Hawthorne, USA, NY

Aspen Aerogels and Cabot Corporation are the only companies manufacturing aerogel for commercially viable end use applications. Check out www.aerogel.com and you will see the miriad of aerogel applications currently in use. And yes, consumer products will be available with aerogel technology this fall. Several footwear companies are launching: Timberland Pro workboot, Redwing and the Vasque group's high altitude hiking boot and Salomon to name just a few.
The R value on the mat or blanket products produced by Aspen Aerogels is approximately R10/inch, a vacum is the only thing better.

JB, San Francisco, USA / CA

The question most of you seem to be argueing about is the thermal conductivity of Aerogel, compared to other materials, I looked it up on some internet sources to get a idea of what it was…
0.03 W/mK down to 0.004 WmK (Aerogel thermal conductivity, Wikipedia)
0.05 W/m-K (same units) (Fiberglass thermal conductivity, Wikipedia)
0.024 W/mK (Air thermal conductivity)
1.05 W/mK (Glass thermal conductivity)

W=Watts
m=Meters
K=Kelvin (think Degrees Celsius)

Also,
“R-values can be calculated from thermal conductivity, k, and the thickness of the material, t: R = t/k. Thus, for 100 mm thickness, it is possible to calculate that a fiberglass blanket has a value of 2, whereas aerogel has a value of 5.9.” (looked up R-value in Wikipedia)
So, it looks like to me aerogel is 4 to 10 times a better insulator then fiber glass, and a whole lot better then your windows, which is where most modern homes let in/ loose a majority of there heat from.
Its not that hard to look up.

"Speaking to (Mohammed) If we didn't fight wars and WIN WE WOULD NOT BE ABLE TO DO ANYTHING GREAT!! We would be under a DICTATOR!." ~ Richard, Lompoc, USA Ca

Sir, a person who thinks that a very small, (compared to US military) 'disorganized' and 'unmilitarized', group of cave-dwelling people called 'al-qaeda', will invade and destroy America (who has spent a gazillion dollars on sophisticated military hardware, not to mention thousands of nuclear weapons) in order to install a 'dictator'...is not a very bright person. I could go on, but lets not try to derail this great topic. Thank you!

Mohammed, London, UK

If aerogel is as ridged and insulates (survive dynamite blast and 1300 torch) just think of airplanes, car bodies and subs that can be built that would use only a fraction of the power to do the same work, i.e. a 747 that weighs 10 tons instead of 130 tons....

Mike Smeltzer, Beulah, Michigan / USA

Re: Doug from Knoxville, I get so sick and tired of skeptics and cynics.

retrometa, los angeles, ca

Touché, regarding the usage of the term "miracle" in the opening line of the article. Oh, what's that? "Miracle" has a secondary sense, which allows for figurative use? And DuPont -- perhaps the mother of all chemical labs -- uses "The Miracles of Science" as its company slogan? Never mind ...

If your deepest desire is to see "not one person on this planet going without", then work to spread our values -- because wherever you find deprivation today, you will find a lack of capitalism.

NJ Citizen, Monmouth, USA

Does the aerogel stop radiation? In space flight, presently, it is imagined the battle to maintain healthy human physiology (which is harmed by solar radiation and cosmic radiation, which maybe nothing can stop) may rest on the role of nanobots to conduct ongoing cellular repair and genetic restitution. The computational platforms of space flight also need protection from solar radiation storms. If the shell of the ship is insulative and protective, the platforms will need less protection and aid in weight reduction. The aerogel could be used as insulation on the moon.

Can it be used like carbon nanotubules as in the space elevator cabling?

What a stunning example of a science driver for expanding an economy, with beautifully useful yet unforeseen opportunities. Space flight demands accelerate discoveries so we can replace the military economy with better economies that extend the beautiful opportunity our solar system has given us.

Should Osama Bin Laden be killed?
Hmmm... I think the families of all of those that died on 911should have their chance to comment on that. My personal opinion is that he killed a lot of the "working class" people that day. These were people, that went to work that day, among them children that were in a pre-school setting, not military men and women.
Is that because he didn't have the moxie to attack out fighting men? Now he lives in fear, fear of showing himself. Fear of being able to live like a man. Now he lives like the snake that he is, slithering back to his cave whenever he feels threatened. So be it!

Vince Leonardi, Somerville, MA

Please stop trying to explain how insulation and thermostats work. If someone reading this article really doesn't understand either of these their troubles are far more reaching then just not understanding heat loss. Reading these comments were at first enjoyable until every amateur scientist here thought "What a great chance for me to sound smart by using words like 'radiance", 'heat-transfer', 'R-Value' or my favorite line yet "You DO have to turn your thermostat ahead of convective heat or cold intrusion to maintain a given ambient temperature". I would venture that if these people don't understand basic concepts of heating and air conditioning the word "convective" is going to elude them so why waste your time? If you would take the time to read more then the first 3 comments you will notice that this topic of discussion has been beaten into the ground. And if you're one of the people who think you've "Figured out" how this heat thing works please stop posting all together.

Mr. Kirth, It is entirely likely that the heater indeed does not run nearly as often. As to the temperature setting being 5 degrees lower, that will likely result from the vastly improved insulation of the entire dwelling.

what is the cost and availability of aerogel or like so many

eddiemcconway, new york , usa

It s not that I am blasé, but your title reflects the modern transformation of the process of development. Any ‘change in the world’ that would threaten the current pecking order is unlikely to get into production. The whole business of research and development is so politically sensitive that nobody need waste any nervous energy on the possibilities of new products. Anyway, some of the more banal developments have proved most useful. The development of the solar cell, which has been around a lot longer than frozen smoke, would do far more in an energy context than this material.

The thermostat can be set lower because the heat from other sources (lightbulbs, cooking, human bodies) raises the temperature above the thermostat temperature. They could probably turn the furnace off altogether and not notice a difference, at least in the daytime.

Speaking to (Richard, Lompoc, USA Ca) - you are living under a dictator and you have lost the war in Iraq.

Don't let the truth get in the way though, just wave the flag a little mroe urgently and CLAP LOUDER!

So when the US man rep says "we need to kill Osama Bin Laden" that makes the difference between right and wrong like what? it is not right just because it's your side.

To Richard Lompoc: That's not actually true though, is it? In fact, it doesn't even address Mohammed's comment, plus you seem to have accidentally hit caps lock while typing... either that or you are a very angry man.

On the subject of aerogel: does anyone know if it has any negative properties such as poor compressive strength that would prevent it being used in construction? If not, then woo hoo!

Speaking to (Mohammed) If we didn't fight wars and WIN WE WOULD NOT BE ABLE TO DO ANYTHING GREAT!! We would be under a DICTATOR!.

Often, the extra efforts to insulate a home can contribute to better retaining moisture as well as heat. Higher humidity within the dwelling can allow you to run a lower air temperature and still feel comfortable.

Ken, Houston, Texas

as far as the absorbtion of oil goes it shouldn't be too terribly dififcult to squeeze out the oil, thereby saving some of theat for future use, then reusing it to soak up more oil? and as silicon is a fairly stable material it should last awhile. just look at computers- more effort is spent recycling the metals in an older unit than the silicon. but let's keep an open mind about this; who could have predicted, 25 years ago, how computers were going to radicaally tansform our lives for the better?

Shane, Unknown, USA

I can't believe I just scanned dozens of posts about the effects of an improved insulation. Good grief.

Move on - the key issue isn't the man's house or thermostat. It's the aerogel and all its possibilities.

TH, San Mateo,

Its an interesting article. I suspect the price will come down as production goes up. That is the trend for such things.

So, protection from the cold of deep space might be solved. Now all we have to worry about is the radiation. A leadened spaceship is probably not going to fly. Does Aerogel offer any protection from radiation?

I've had fun reading all of the inane flak going back and forth about an innocent remark by Mr. Stoker. I think you guys really miss the point of the article.

Sometime in the near future Al Gore and Jesse Jackson will be making claims that Al invented it and that Jesse needs it to be given to more of the underprivileged to keep their ghetto shacks warm in the winter time.... it's only a matter of weeks, I suspect...

William R. Smith, Marietta, Georgia, USA

It is unfortunate that a great innovation like this is under-appreciated. For those of you that focused on Mr. Stoker, shame on you. All you wannabe enviro-activists should have focused on the ability to absorb pollutants from water and protection from high temperatures. Instead, you argue and bicker over 5 DEGREES. I couldn't care less about my thermostat bill or what you have to do to keep your home comfy, what does concern me is what we can accomplish with this material.

I saw this very product featured on the futuristic TV show "Beyond 2000" about 12 to 15 years ago. Every time I read about the space shuttle tiles needing repair I thought of this product. Since seeing the product on the TV show I have not heard or read anything about it until seeing the article above.

Hughie, Phoenix, USA

Nice to read that such a fantastic new product yet again is an invention from within the world's most advanced civilisation. And it is not a weapon - how refreshing. Though with some claver application might just render impotent those of Al Qaeda.

Peter, Auckland, New Zealand

Theromstat comment was truly dumb, if you think about it. True, there are many factors as to where the thermostat is in the house and variances in how well different parts of the house are insulated. However, to get a across the idea of how much energy you save, you dont mention thermostat, you mention how much gas or electricity was saved at the meters. This is not rocket science.

K Michaels, Orem, Utah

And how much incentive are the local government planning committees going to need to allow this one onto the market then? I can hear it now - "We've no need for that new-fangled stuff around here. Cavity walls were OK when I were a lad and they make more profit (sorry - cost less to build)". Then there's always the power generation lobby. Following this article, look out for a response based on lack of long-term safety tests, or any other reason that might prevent us from spending less of our hard-earned dosh on their energy.

At risk of repeating a comment from last week - if you want to get low-energy, green-friendly products and systems, design a spaceship. Thank God NASA is working again.

KR, Stockport,

Lordy! I've never, in my life, seen so much cross-jabber devoted to something as off-subject as the whys and wherefors of the tempurature level some guy decides to set on the thermostat in his house. Reminds me of the title of a shakespearian play.

The article was supposed to be about the beneficial uses of aerogel...of which there are many. And the more its use finds its way into the private sector, the less expensive it'll become...thanks to free market competition...as calculators, computers, and other formerly high-priced technological advances have become.

DJ, Yuma, Arizona/USA

Sounds like a great material. Hopefully, they will use this to produce full body suits for fire-fighters.

If Americans invested their wealth creating wonderful technology (instead of fighting illegal wars), they'd be regarded by the world community as 'true' world leaders.

Aerogel is just another way of saying "gimme gourds or gimme death!"

max spilliane, boulder , colorado

The author of this article mistated the synthesis of the typical aerogel. When he stated that the water used in the preparation of the gel was replaced by carbon dioxide, he failed to mention that the carbon dioxide was thereafter controllably removed to yield nano-sized pores in the formed aerogel. It is these nano-sized pores that give the aerogel its remarkable properties. The reason that the typical preparation of an aerogel involves a replacement of the initial solvent (usually not water but an alcohol-water mixture) with liquid CO2 (the carbon dioxide is a liquid because this is done at high pressure where the normally gaseous carbon dixoide is compressed so as to be in liquid form), is that the carbon dioxide can be removed from the porous material without cracking the structure. Generally, the removal of a solvent creates drying stresses; using CO2 lowers those.

T. E. Wood, Stillwater, Minnesota

Could it be used for spacecraft? Why not retrofit the shuttle with this stuff and eliminate the impact problems it has. Plus, you would make it lighter.
Hey NASA does the left hand know what the right hand is doing?

Bill, LaGrange, US/GA

" It is now being used to develop an insulated lining in space suits for the first manned mission to Mars, scheduled for 2018."

Actually, that would be a mission to the moon in 2018. No mars mission is likely in the forseeable future, and it is realistic to say not in our lifetime.

Tyler, Riverside, CA

While I appreciate the wariness Dave of Nashville expresses, not even the technology- and progress- hating Luddites of the environmental movement can oppose adoption of this material as an insulation. Provided carbon dioxide was actually used in its manufacture, the actual carbon content would still be low, compared with truly carbon-dense petroleum products. Bottom line: if it leads to lower energy consumption -- as it promises -- and can be produced inexpensively, it must be used.

NJ Citizen, Monmouth, USA

Mr. Stoker indeed feels better with the actual air temp 5° cooler. This is because all things above absolute zero emit infra-red radiation. The warmer the surface, the more infra-red is emitted. When you are in a room with an outside wall, with that wall poorly insulated, you might dial up the air temp to compensate for the relative lower IR coming to the side of your body facing that cool wall. Remember, your body is also emitting IR and cooling. With little IR coming back to your body, you will feel cold. Improving the insulation in the wall raises the temp of the inside face of the wall. This increases the IR coming to that side of your body, making you feel warmer, even though the air temp is the same as regulated by the thermostat in that room. We would all follow Mr. Stocker's example to lower the thermostat to maintain our comfort if we increase the surface temp of our surroundings. This is why IR heat can make us feel comfortable when the temp is actually quite cool.

JOnny, Belfast,

They had this substance on display at Disneyland 4 years ago. As for getting it to our enemies, I believe they helped to develop it or at least a foriegn national worked on it and has now revisited their native country. I do not think the U.S. will hire native engineers while the 1H1B engineers work so much cheaper.

irv, Long Beach, Ca.

Great article. I am continually amazed at the advances that scientists are achieving. It's truly exciting to imagine the possibilities for a material like Aerogel.

I was surprised to see that there are plans for a manned mission to Mars in eleven years.

Also, a note for the American readers who are perplexed at the lowercase spelling of "Nasa" as opposed to the more familiar "NASA"-- in the UK, acronyms that are spoken as a word instead of being spelled out (e.g., "NATO" versus "IAEA") are not capitalized, but rather are spelled with lowercase letters after an initial capital. So "NASA" is spelled "Nasa", "NATO" is "Nato", etc., but "IAEA" is still "IAEA", "ISBN" is still "ISBN", etc.

Michael, Ligonier, Indiana, USA

The article talks about going to Mars in 2018. NASA's Vision for Space Exploration has astronauts returning to the Moon in 2018. There is no time schedule for manned missions to Mars yet.

If they use Helium instead of CO2 to replace the water, will that make it lighter than air? Or, will the Helium eventually leak out - to be replaced by air?

Joe BH, Lake Ridge, VA

Stoker is correct. For example, Stoker's house may have the thermostat set at 80 degrees, which means the furnace makes sure there is enough warm air to keep the house at 80 degrees F. Now, throw in a few human bodies (at a temperature of 98.6 degrees F), a computer (80-120 degrees, depends on usage), a few other appliances. Now equilibrium has to kick in. The bodies and appliances will give off heat and increase the temperature of the house, but this is counteracted by the loss of heat due to imperfect insulation. By replacing it with Aerogel, you've negated a bunch of the heat loss. It's not that the house FEELS hotter, it's because the house IS hotter!

Billy, Chicago,

It is possible they are over-stating the capabilities of aerogels. Although, there is a legitimate site for Aspen Aerogel and it claims having some of the same abilities stated in this article. Do your research before you completely credit or discredit something.

Wes, Memphis,

Remember the "SEGWAY"?
It was to be the next great invention of the century.
Now I hear they are using Segways as golf carts.

driveinman, douglasville, USA

Setting the thermostat to 71 degrees will mean the heat is on when the air temperature *at the location of the thermostat* is below 71 degrees (ignoring corrections for hysteresis). Better insulation could certainly result in the the rest of the house being closer to 71 degrees.

R Hayes, Mill Valley, CA

If Aerogel is so dern GOOD, the why hasn't the US Royal Gov't taxed it out of existence, or said that making it causes pollution of the false-planet Pluto, or that it caused the extinction of the ring-tailed purple kangaroo horse fly, or that the profits from the sale of Aerogel have not yet been distributed fairly amongst the Members of Congress -- meaning that the MOC haven't decided their cut yet?

James, Safford, CSA

The enviromental-nuts should love this. When we have a way to remove plenty of CO2 from the atmosphere, here's where it can go. Aerogel sounds brilliant, the fashion world can use it to make winter jackets that are perhaps 1mm thick or less. I definitely want to try some.

Ben Taylor, Peterborough, England

Please stop trying to explain how insulation and thermostats work. If someone reading this article really doesn't understand either of these their troubles are far more reaching then just not understanding heat loss. Reading these comments were at first enjoyable until every amateur scientist here thought "What a great chance for me to sound smart by using words like 'radiance", 'heat-transfer', 'R-Value' or my favorite line yet "You DO have to turn your thermostat ahead of convective heat or cold intrusion to maintain a given ambient temperature". I would venture that if these people don't understand basic concepts of heating and air conditioning the word "convective" is going to elude them so why waste your time? If you would take the time to read more then the first 3 comments you will notice that this topic of discussion has been beaten into the ground. And if you're one of the people who think you've "Figured out" how this heat thing works please stop posting all together.

Old folky, topock,

Almost everyone on this post is talking about some guy named Stoker and his thermostat. Who cares? The product that the article is about sounds to me to be AMAZING? Try thinking about all the good the product will able to do, not about some guy and his thermostat.

Mike Mango, Harrisburg, PA USA

So when is the first Prototype Knight Rider Car going to be made with this stuff. I can't wait.

Dave Fisher, Chicago, IL USA

I am in an appartment with an air conditioner. I currently have it set on 60 degrees F.....it runs constantly and the temperature of the room is about 78 degrees. If the room were better insulated I would be able to adjust it up 10 degrees to 70 degrees F... and be comfortable. Changing the thermostat is a product of the effeciency of the heating/cooling unit and the insulation or the room/house. If your room temp matches your thermostat temp....then Mr. Stokers comment may seem weird, but i fully understand it.

Apparently it absorbs moisture so that it feels dry and flaky.

Nick, Leeds,

Now I'm going to say it even though it may have been said. This sounds like an amazing product but it needs to be tested like hell in order to pass so that way it can be appiled. Like for example, it be nice to see how they will dispose of the product once they use the stuff to clean up some oil. They just need to make sure they can find all the flaws first, it would be better in the long run.

Matthew Rogers, Brampton, Canada/Ontario

Not a hoax - read about this years ago. It's quite possible that it moved from pure research to R&D with many companies. Materials science is one of the most over looked areas of research in science. It's good that it is getting some coverage.

Now, if only they would produce a new shuttle with this stuff!

Bob Dobbs, Dobbstown, Malaysia

To Doug in Knoxville...... what they mean by experimental is by the other ways they are going to use it, like as in blast absorption and insulation for space suit. I say again, what they mean by "experimental" they mean they are experimenting in new uses for the material. Don't be so critical because of a single word.

Stoker is not stupid. monnit should know that a thermostat only measures the temp at a single point. The temp of the entire house would be based on the factors around that point.. Only someone from france would discard the rest of the article.The US has been worried about your priorities for a while.

Chris Hargrove, Pittsburgh, USA

Is anyone asking where us dumb humans came up with this stuff? I mean, when is someone going to admit we developed space age technologies from our discovery of alien life???

Mike, Orange County, USA/CA

A well designed heating or cooling system goes to the temperature set on the thermostat. Having to set the thermostat 5 degrees higher than you want the room temperature to be is so rare that I, myself, have never seen such a stupid design of a heating or cooling system. Also, why would the writer call the lubricant silicone a wonder product? He could not be confused between the lubricant silicone and the chemical element silicon because silicon was not developed in 1999. It has been with us always. Maybe he meant the use of silicon in modern technology.

CarlNB, New Braunfels, Texas USA

1) Saying it's made of Carbon Dioxide so environmentalists won't like it just silly. If it's made from atmospheric CO2, it will have a net effect of LOWERING the amount of CO2 floating around.

2) Insulation in housing is a good thing. You have less leakage of heat, period. This means your AC works better at keeping your house cold because less heat gets in, and your heating works better because less heat gets out.

Nate Williams, Jacksonville, FL

Awesome!!! Cant wait to see it work. Amazing what this planet has to offer if we just try!

Eugene, owings mills, md

True, aerogel is still very expensive BUT if installed as insulation in a building, it will pay for itself within a year. It is the best thermal insulator known to man. There are several popular experiments demonstrating this using a bunsen burner (burner on one side, and crayons on the other side less than half an inch away don't melt, matches don't ignite, rose petals don't burn etc.)

It's also an environmentalists dream as it traps CO2 in a solid form and it degrades to mere sand when disposed of. Yet another example of how progress and environmentalism go hand in hand.

Zac, Atlanta,

I wonder which company will add this product to interior/exterior paint to help insulate homes. Since living in a hurricane zone of Miami Beach, I wonder if it can strengthen my bunker styled home? Really neat product, I am anxious to trade in my sleeping bag for one that is lighter. I now have a great excuse to delay painting my home, and upgrade my camping gear. Life doesn’t get much better than this!

Hanson, Tokyo,

Unbelievable, so much talk about the thermostat. Have you never been in an old house that feels much cooler than the 68 degrees it is set at or near a curtain less window. It is actually quite easy to believe that with such good insulation the temperature will "feel " warmer than in a drafty, poorly insulated home. Dare I say that it might make it stay cooler in the summer with the same amount of energy expended to cool it as before. I will say though 9 degrees or so Fahrenheit makes it seem a lofty claim.

Jeff, Buffalo, NY

Ive actually handled this stuff about 4 years ago. One of the wierd perks of working for Disney. The stuff is so lightweight that if you close your hand around it, you cant even tell its there.

Mike, Anaheim, California

This all sounds great, but how do we dispose of it when we are done with it?

Erin, Raleigh, NC, USA

In order to alleviate your CO2 panic you must realize that plants metabolize it and turn it into oxygen. The more they have, the faster they grow so quit cry'n about it. I hate to quote Carter, but just cut the heat off and put on a sweater. Put a row of 55 gallon drums full of water or oil under your back deck.

Shane Grimsley, Richmond, Va

- Disposal may not be an issue. Aerogel is primarily silicone, which does not decompose. Silicone is also relatively inert, it should be pretty easy to clean & re-use, making disposal a moot point.
- Pollution occurs when a substance is out of its normal environment. The trick is to collect the substance from the abnormal location (seashore, riverbed, tundra, etc) and return it to its proper locale. Again, since the stuff appears to be inert, it should be easy to "empty" and reuse.
- It appears the insulating properties are beyond most people's understanding. Most discussion in the article is about items (jackets, boots, etc) being too hot. Wouldn't it be great to have a the equivalent of a winter parka with the flexibility and weight of a summer jacket?
- For Charles Miller re the Stardust probe: please see photos of the INTACT Stardust capsule (http://stardust.jpl.nasa.gov/photo/landing.html) after landing.

Tony, Hamilton, USA

I am in the home building industry and am very curious about this product and it's insulative properties.

Does it trap and hold mold?

Who is manufacturing it and what is the cost?

Does it slump over time?

Does it lose it's insulative properties over time?

As a dessicate does it dissipate the mosture or retain it?

Someone please enlighten me!

Kyle, Houston, Texas

I lived in the UK for a year, and the only thermostat in the house was for the boiler. There was no thermostat for setting the temperature of the house, only of the hot water circulating through the radiators. On cold nights we had to turn up the themostat to circulate hotter water through the pipes. If we forgot to turn the thermostat back down, the house would be like an oven by afternoon. This type of heating system is common in the UK, at least in the southwest, where even new homes were heated this way.

Ron, Mtn. View, CA

If I may add to what Mr. Prince stated: There is a heat source in a home that is always running when the house is occupied, thermostat or not: the person who is occupying it. The average person generates approximately 80 to 100 watts of heat. This is additive to whatever other heat sources are in the home. If a home had perfect insulation, it would theoretically be sufficient to have *no* external heat source in the home. In fact, it would be required to cool the home to remove the heat generated by the occupants.

Paul Theodoropoulos, Rohnert Park, California, United States

Isidro, here, here. Mr. Burke's comments make no sense to this Pentecostal Christian who's an independent Conservative, politically speaking, and sees man's abilities to produce such products as miraculous. Either way, who cares about such religious trivialities as to whether or not a material is described as "miraculous." Just get it into products ASAP in a free market system- and for those striving to create an alterntive fuel to petroleum: I'M BEHIND YOU ALL THE WAY!

ruben, bismarck, nd/USA

The point about the thermostat is that because the insulation is more efficient, the home requires less constant throughput of heat in order maintain the same comfort level of warmth. It actually makes perfect sense, especially in light of the fact that everyone mentioned the use of the product as a personal insulation as being too intense--Hugo Boss "complaints that they were too hot" and Anne Parmenter "my feet were too hot". Obviously the product is quite effective.

Melissa Glasscock, Opelousas, Louisiana, USA

The areogel insulates his home from the cold outside and keeps heat from escaping his home better than his previous insulation, so he does not need to have his heater set as high. Thus he turned his thermostat down 5 degrees.

Dictionary.com Unabridged (v 1.1)
in·su·late
[in-suh-leyt, ins-yuh-] Pronunciation Key
–verb (used with object), -lat·ed, -lat·ing.
1. to cover, line, or separate with a material that prevents or reduces the passage, transfer, or leakage of heat, electricity, or sound

PL, CC, TX, USA

I think what he's saying is that the insulation reduces his heat loss (a leaky home can have almost instantaneous heat loss) to the extent that he can turn down the thermostat and be as comfortable at the lower temp as he was at the higher temp.

With bad insulation you have to heat the home to a higher temp than needed to account for heat loss. With this stuff I guess he does not have to do that.

Bill, Annandale, USA/Virginia

The thermostat comment could be justified by the location of his thermostat and the insulation in his house.

In a poorly insulated house, the outer rooms could be drafty and cold. Thus, he'd have to raise the thermostat to get those rooms to maintain a comfortable temperature.

With good insulation, the outer rooms would be more comfortable and he could lower the thermostat setting.

Brian, Washington,DC,

Mr Stoker may in fact have a point. The assumptions that decreasing the thermostat 5 degrees will result in a 5 degree reduction are correct. However that would be a 5 degree reduction at the thermostat and not perhaps in the far corners of the stucture which may well now be much more comfortable allowing the 5 degree reduction at the thermostat.

Scott, Lumberton, USA/NJ

This is a revolution in practical material applications if the claims hold true.

Imagine that, a scientific advance taking place in a country where freedom of thought and action is the rule.

Yet , responding to nothing in the article itself, a few previous posters here have to malign that same country with "too bad so much time money and human "intelligence" is wasted to kill each other."

You don't get the advances without the freedom to create them.

And you do not have the freedom if you do not fight for it.

Wishing it were otherwise does not accord with reality.

The CO2 in use for this product could be captured as the end product of burning of fossil fuel and then trapped in the matrix of the aerogel, rather than allowing it into space. Thus, it may well be very environmentally friendly. ---a friendly "environwhacko"

The "reporter", Abul Taher, is a little confused. Aerogel is from the past, not the future. It has been in production for decades. Dozens of varieties of Aerogel are used in thousands of applications every day.

What vested interest does Abul have in hyping Aerogel? Don't be a sucker.
