- The high cost and vulnerability to the forces of nature make conventional stick houses foolish. The 3 little pigs taught us that in kindergarten. How about we build solid Aircrete brick homes that aren’t damaged by water or high winds? A fabric reinforced AirCrete dome home is much more durable yet costs only a small fraction of conventional housing.
The son of an inventor, Hajjar Gibran’s youth passed building tree houses, hot rods and tiny homes, and he was already a skilled designer & builder by the time he finished the engineering program at SDSU.
He built his first passive solar home in Nova Scotia, winning several awards from the Nova Scotia Design Council. While building The Gibran Center in Thailand, Hajjar developed an innovative way of building beautiful low cost AirCrete domes that has gained international recognition. Hajjar founded Domegaia in 2014 to answer the global demand for his innovative low cost housing designs. Visit him at Domegaia.com This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
Absolutely fantastic! I'm a 70 year old single woman who hasn't yet owned her own home. And when I learned about green building, especially aircrete, I knew I would learn how to build this way and finally have my own home! Can't wait! I continue to research......
My husband is a contractor and has also worked for many years in the commercial concrete business, he is about to go to one of his workshops in February. Hopefully my husband can incorporate this building material in his business. He will be building us a dome home on our land soon.
Awesome!
Have you built your dome home?
Yeah, I have been "enrolled in a research project" of recent "at the University of UA-cam" myself! Loved it! LoL!! Very fresh and necessary insight from a great sage.
Great presentation Hajjar. The Mexican workshop will always remain a highlight of my LIFE! I am about to embark on building my first dome at home in the land down under WITH the blessing of council as a pilot project. WooHoo!
Hey did u take the worshop with him?
They are comming to tulum, mexico this january ,think im going.
Do u recommend it?
Kathy Coles How was the workshop? I’m looking to go to the workshop in Costa Rica soon. Is it easy to learn?
which council and did you use an existing dome builder to build it for you ?
This is amazing and to think it has been around for years. Spread the word, keep building to open the eyes of others on how to do this. I had already planned on using this method for my "She Shed" and was viewing UA-cam for updates on Aircrete and found this video. I hope the dome in Hawaii isn't in the active flow of lava that is happening.
New materials like this are fantastic...if you can find a contractor to build with it and get the plans through the permitting process. After all that, you still can't get a mortgage on it. Even if you have cash it's hard to find a contractor. We discovered that the biggest challenges to building a dome home are not technical. They're logistical and regulatory. Florida should be the concrete dome capitol of the world but there are only a handful in the entire state.
There are many in the Gainsville area.
Honeydew carpenter channel has developed a cheap foam machine (100) and is coming up with some innovative ideas
According to him, he no longer has the machine.
I love this SO. MUCH ❤️ I'm so over living in toxic homes. Wood and insulation are nothing more than mold and termite food. I want to take this class and start my own Bussiness, utilizing Veterans to build to help each other and the community. So much yes. this technology is SO needed.
I'm STOKED to get in on this. First chance I get I'm doing it.
I hear ya loud and clear and I am a veteran
Wonderful I loved it. Wish this technology could be available in India.
I am in the process of building a Retirement center in north Baja Mexico, originally i was going to use paparcrete, but i am totally exited about using aircrete, 5 years ago i build a studio for my worker Rafel, using papercrete and he is very happy, but i am now going to start this project using aicrete,
How did it go?
I knew I loved this man for a reason, my favorite author is Khalil Gibran ! There’s such a poetic spirit that run through these men
Lucid presentation by a very intelligent and charming man. I'm starting an aircrete business soon.
Miguel Filo are you going to build a dome home?
What about hempcrete?
@@There-Is-No-Virus My understanding is that hempcrete doesn't have the structural strength for making load bearing structures. It's typically used for insulation/thermal mass around a conventional wood framed structure.
Right :-)
I would love to fine a builder Indiana for this type of home
I want so badly to be involved with your school and rebuild my whole town of 729 people town called Traver California 93673. I am homeless and I am willing to devote the rest of my life helping the homeless here in the central valley.
I wish you the best with your inspirations. God Bless You
I hope you have a home now.
How many homes have you built?
@@williamreilly3172 a lot
From one homeless person to another I hope you got back into a home .
I’ve been homeless for over 6 years now .
I want a practical aircrete instructional video, seen plenty of these oh wow type of vids.
Oblivious Captain ... Hum ... Why make mean comments?
There are plenty on UA-cam if you just search aircrete pour or how to make Aircrete
If I could be half as cool as him, .....what an awesome dude. The aircrete dome home is an excellent idea. If I could buy a little time living in one to see if it is as nice as it looks, I would be "onboard" 110%.
In the failed egg example, I totally know what he was attempting to do but was not able to offer a rebuttal. He meant to say that you should try an experiment with an egg, but the egg must be long side between both your hands. Then you try to crush the egg lengthwise. If you like to try it, it will not be able to be crushed because it is incredibly strong lengthwise but if you were to do it with the short side between your hands, then it would be crushed immediately.
Ooooooh
Well. Aircrete as he calls it is not new. Many years used in Europe. Biggest companies are Ytong and Hebel. He actually uses some of there product videos to explain his "aircrete". So no. Nothing new. Specs aren't provided by him as needed by home inspectors or engineers. Because he has none. Ytong and Hebel would have to close their factories without providing specs of their stones. Only new is that North America does not know about stones used in home building around the world. I did build my house with Liapor. Much better than "aircrete". I actually consider to go to one of his training program to see if the stones made of equal quality like Ytong or Hebel. But I think that they are not!
He very clearly stated that it is NOT a new building technology, neither design nor material. He mentioned the 2000 yr old Pantheon dome and Roman building materials very similar to aircrete and that Scandinavians were using it 100 years ago.
Did you actually watch the video? 🤔
I want to work for this lovely man and his fabulace mission
What a kind man, and how sad that only 37 000 people have seen this in a year...
The thing is .... how do you build alternative housing with government inspectors and building codes in this age when "only the government knows what is best for you and your children" mentality?
Sir, i want to build a dome home in my village in karnataka, India. Please help me ...
Aw, my heart goes out to you friend. I love the Indian people, and am increasingly frustrated by the gvt there not doing more to help clean up the environment and help people out of poverty. A dome home would be a wonderful way to bring a village together. Wishing you success in finding help to do a workshop.
Let's crowd funding your home!!!!
Ya , we too searching. Does anyone doing in india?we wanna build in tamilnadu.
@@catlover4219 India is a very diverse country it's young population is both an advantage but also puts pressure on the environment and resources. The present govt is carrying on the worlds largest housing, sanitation and water scheme. It is also doing its bit to pass on benefits to the poor and remove poverty.
@@suneetsalvi1200 which present government? Under the Modi government india become 115th from 45th in world poverty ranking. People are dying like insects here.
That’s really awesome! I’m building a pole barn house but I would love to do this sometime in the future with in floor pex tubing radiant heat for the cold north or just move somewheres warm if I can convince my wife. 😉
Smart Easy DIY would you add geothermal?
S O yes you could use geothermal to heat it if you had the right system. It would take up some room though probably. Maybe you could put it in a smaller separate area and run the heat inside.
I noticed all the builds are being done in warm climates and many are NOT main living spaces, but out buildings. My guess is due to code restrictions like here in so cal, home of building Nazis and elitists. Wish some super legal mind could get legislation that would work around the absurd bldg. restrictions here. Forcing expensive solar and banning AirCrete...
i love this idea. Just learned about Aircrete dome homes yesterday and this is the second video i seen on the subject. Hear they can survive through tornadoes too. Now i would like to create affordable tiny villages across America with its own off grid power, food and water supplies? Would love to talk to that guy speaking in person if possible?
I also went to the university of UA-cam, learning to build my own dome
This all sounds nice but you still need land to build and land in most places, like the Seattle area has been down-zoned to keep it from becoming one huge suburb. So - as population increases the available land becomes too expensive for even middle class people to afford. Add to that the importation of people from large family cultures and I don't see affordable housing anywhere on the horizon, even if you can come up with inexpensive building material. Yes - it seems absurd that people build with materials that can be burned down or blown away. I hope you can get the building departments on your side. If I ever build again I'll certainly look into AirCrete.
Gold Hunter I am also waiting on the okay to use aircrete. I believe it's how they keep us buying the same old same old stuff. The public needs to vote in fresh new ideas. Stop waiting for those in office to die.
Agree! I'm tired of being told I can't use this, and that I must add solar and specific types of lumber. Ugh. I live in so cal, and our leaders are anything but supportive of the environment. All talk. They only push expensive new building that THEIR investments will benefit from. Politicians don't care about the common person or the environment IMO.
On hawaii the best building material is already there it is Cindercrete mix cinder with cement and water and pour into a set of forms
very accurate plans for something like that I found on Avasva
It is a problem caused by city and county permit requirements. Let people build...
The egg was unfortunate. lol. Is there any footage/information about the collaboration with Mike Reynolds? I would be very interested to see how you combined the technologies.
No birds nest buikding inspectors
The concept of Aircrete sounds great. However, I would like to see homes built in a more angular structure. This is because placing furniture against rounded walls can be difficult. I presently live in an adobe home in Ecuador, where most of the lower socioeconomic families live in homes of adobe construction. However, adobe is meant for dry environments (ie, New Mexico, Arizona), and, in Ecuador, half of the year is not dry. Aircrete sounds very promising.
Susan Fitch the frist 6 feet of your house should be nearly straight.
Check out 'Aircrete Harry' videos. In some of his more recent ones, he does a tour of some dome houses and it's amazing how much space is usable and how little isn't. Might also want to check out 'Honey Do Carpenter' channel. He's done some really interesting things with aircrete.
Aircrete is fine but the cost the of material is higher and it has a higher CO2 and energy footprint. While a earth based adobe or cob construction, can last hundreds or even thousands of years when designed properly. Its roof, foundation and landscaping along with the use fibers and the use of exterior protection are key factors. Such as breathable but durable plaster mix and a lath/mesh are all factor on how durable and maintenance free or not the structure will be. Reply if you have any questions. And good luck...
LOL @ Square Furniture. !!
Try picking your designs from pieces... AND BUILD IN-SITU FURNISHINGS.
@@nc3826 can you explain why it releases high energy footprint?
Compressive strength is low even when able to carry a car. Do you have compressive strength and specific weight figures? Shrinkage? Thermal insulation values? Are fillers e.g. sand, added to the aircrete? Hygroscopic properties? Can aircrete be used for load bearing structures? Steel reinforcement possible? Corrosion protection of reinforcing steel needed within airated concrete? Carbonisation rate of air crete?
Cement additives used?
How to calculate the integrety of an aircrete structure to comply with building regulations?
Thanks in advance for your answer.
Making cement causes lots of CO2 ...is aircrete eco friendly or green nevertheless?
When the physical properties of aircrete are not known or not reproduceble by the civil engineer architect or contractors, design will be based on lots of guess work... How to be sure it complies with the Building Codes ?
Hi Hajjar, is it possible to use rice hulls in the Aircrete mix As in the Philippines you can get them for free buy the truckload???
Does anyone know what happened to Hajjar? Domegaia has been abandoned as far as I can tell.
No!! Really??
Also from the University of UA-cam, I'm hearing that concrete and graphene mixtures benefit by being stronger, less brittle, and lighter. Is there currently such a thing as graphene aircrete? I'm not a builder, but I'd be curious to know if anyone's tried it or is considering it.
Impractical, graphene is expensive
@@franchocou we havent figured out how to cheaply make graphene and in bulk. Laurie. NZ 😊😊
Awesome speech. Funny and great content. We certainly need these kind of houses here in Hawaii with the hurricane scares, lava, and flooding we had last year in 2018. We have seen it over and over again, the current structures we are using get demolished during a hurricane and yet they keep using the same material to rebuild. It makes no sense. Thank you for sharing and doing the work you are doing!!!
One great lecture from a philosophical mind. Thinking n dedicating time n passion to solving one of the biggest problems in our universe. I applaud your genius 💪👌
Hello Sir
You are really really inspirational!
Love the idea.
Cannot afford your workshops as they are in USA area.
I am in poor Africa.
However I could be instrumental in organising a workshop here, and also be part of it.
Let me know how to get in touch.
God Bless
Aloha.
Montana needs this technology BADLY. Especially on the reservations.
Oilstories yeah imagine these dome houses with radiant floor heat! That’s one of my future projects I’m hoping.
Just check around, there are videos explaining how to make the equipment for making aircrete for $30 bucks. It's just portland cement and a foam made with soap, mixed together. Just use some finer metal mesh as reinforcement, and seal the surface if exposed to weather or wear. It's no secret or super complex thing, you can get going tomorrow.
The extra machinery you need compared to normal cement is an air compressor and a foaming device. The saving in concrete and re-bar obviously makes the result cheaper despite the extra equipment. The foaming device is easy to make with some tubes and steel wool. Just look for videos on DIY aircrete. Go! :)
I'm totally gonna try this for making my new workshop.
If you are able to get an engineer to approve the aircrete let me know I will move to Montana.
The concern there is the covering, as all the builds are in mild climates. Montana is pretty extreme, and the temp flux is pretty drastic. Not sure outer fabric would hold. Shouldn't stop the tribes from trying it in their own jurisdiction though. Feds wouldn't care if you made it from Legos; it's state and local building codes you have to out-maneuver.
Why not check with the BIA to see if they could hold a workshop in one of the reservations? Could serve as a mini-museum or playground amenity for example. Might inspire more.
Could we use hempcrete with the same concept?
PLEASE EXPLAIN WHAT IS THE LAMINATE A LAYER OF FABRIC ON THE SURFACE SOME REINFORCING FABRIC, WHICH MAKES A COMPOSITE MATERIAL THAT HAS BOTH THE TENSILE STRENGTH AND COMPRESSIVE STRENGTH AND ITS A LOT SHEETROCK
not every one likes domes, We need commercially available aircrete blocks here like they sell in india
Since this house is made with some cement, can the house "breath"? thanks
Love what you're doing Hajjar, I've picked up little dragon and have several projects I will be experimenting with soon :)
ramhornjoe how is your projects going. We also have been playing with our little dragon. So far when we stay true to the aircrete recipe. It's wonderful. I see so many people adding to it. And not making aircrete. I wish they would stay true to aircrete. Because I want this to be approved for building in the USA.
Domes are stronger because the forces are spread out over a large area, unlike our framed homes that have many weak points because the force is not spread out.
So, it's not strong enough to use for traditional rectangular buildings?
Hello sir,
I remember in the oilfield industry, using a polymer foam in coiled tubing, in water producing wells. I wonder if these bubbles would be more sustainable with it as they had to have their bubbles last hours long in varied temperature differences. If you can find that particular polymer foam agent and test it to see if it lasts longer dollar for dollar, it might be an alternative.
Thank you for all your efforts and God bless you.
Jay Dixon - this might have been what my brother was describing. Is it the foam used for pumping out the drill shavings? He said they would pump it down the well and it would carry up all the small rock fragments produced by the drill head. He said the gravel sized rock would be suspended in the foam.
Can we have a workshop in the states? I would love to go to Hawaii but this isn't in my budget, but I still want to learn.
Am definitely sold on this type of home construction but the only roadblock encountered is obtaining financing as we own a piece of property in Connecticut for which conventional financing is very stringent. Of course there is the concern of town zoning approval for which I can tell you that this type of construction far exceeds our towns building codes.
Sedona is the least Arizona part of Arizona, bravo, geodesic domes are easy too.
I would just like to verify that I have done the egg thing myself, and he is right, however it is also easy to have the egg slightly off in your palm and screw it up.
And how are the banks reacting to us building inexpensively? Our masters.
Hajjar how are the homes in Hawaii surviving ? Id like one of these dome in Philippines. Thanks Be blesed keep up the good work.
Hi Joe. I'm also living in Philippines. Going to build a few domes in Siargao. Would be great to share more ideas. I know one guy in Cebu that builds these domes with Aircrete.
Harm is there any way to contact your friend in Cebu?
Harm Rietjens did you start building your domes?
What about hempcrete?
Hemp just makes concrete weaker and have a shorter lifespan
have you done any projects with the monolithic domes?
The cost of land is a major factor in people having a house.
I’d love to have a aircreat home! I live in tornado ally of Oklahoma!
I thought this was Serj Tankian of System Of A Down at first.
l want to build a dome bathroom in oz still trying to get some info on a unit to start to make aerated concrete where to buy?
You can shop for the Little Dragon Foam generator online, or if you are handy, you can find several DIY, youtube videos on how to inexpensively make your own foam generator.
This would be great with a bamboo frame
the biggest plus is R factor....
I love this man he is my strength to the full armor of God
Very nice,would love to have one
Florida needs affordable homes
Where can I get the technical specs on this. What is the compression strength with and without reinforcement.
Aircrete or fibre reinforced aircrete can vary from 0.9 to 12 MPa depending on mix ratios
Love this man's heart and mind
Bible reads that we’ll die by our own laws.
A bullet from a white cop is just as effective.
Aloha, Hajjar, Mahalo nui loa for your service to humanity!! Aloha nui from Hilo!
What is the fabric used to reinforce?
And what is the binding agent or adhesive used to apply the fabric to the aircrete?
Sounds like a no brainer.
What a great presentation.
not the egg breaking omg
Air water food then shelter. How long can you live without each one?
Air water food clothing n shelter perhaps
Clothing is part of shelter.
Depends on the climate... if you're in too cold a zone without shelter you'll freeze to death in a matter of hours... even with a full stomach.
AND TIS DIY ....
Add SODIUM SILICATE to seal it...
... which will also fireproof wood.
P.S. .... Sodium Silicate is also used to store eggs long term.
Absolutely fascinating and a wonderful presentation.
Brilliant
Lava Zone One. Aircrete Caverns. Song titles or album names? Beautiful. Thank you very much. We hope to host a workshop some day. Go to your Womb! God Bless
Wow what a spectacular speech, thanks. Aircrete never ceases to amaze
Would you please come and bild me a dome ?....create a workshop on my land in Brazil?
Eggstraordinary presentation.
Concrete is by far the worst offender in regards to the environment in our sector and cannot understand why this hasn't had more coverage and investment. Brilliant product, brilliant presentation, brilliant platform! BRAVO
So is it a good alternative for concrete? I mean its lighter that concrete right? So it must also mean that it can be easily swept down by strong winds and massive flood. Pls do correct me if I'm wrong.
Did he just say the walls are made with dish soap, flour, and whipping cream.... people are getting better
is there a study contrasting aircrete and hempcrete?
Scott McIntyre maybe they can be combined now that would be cool
Not sure but I saw a hemp car once back in the 70's that was great!
It was in a movie lol
Hempcrete is not load bearing. Could perhaps be combined for the insulation properties.
Are nomads who carry their lightweight shelters with them like a Teepee ⛺️ homeless??
So I gather that aircrete has good compressive strength but what about tensile strength? There are a lot of seismically active areas around the globe. I just don't know if fiber mesh would do the job since not many specs were given. The tropics, which are home to 40% of the worlds population, are closer to the sun so housing needs to be either shaded or cooled to keep them livable and I'm wondering how this can be achieved? I like the idea of dome homes but perhaps a reinforced concrete post and beam cage with aircrete infill walls and an aluminum roof would be more appropriate...at least for areas out of the typhoon belt. I have plans to build a house of this type but, with a double roof for shading and passive cooling however, I would rather build an aircrete dome house or series of smaller structures connected by enclosed hallways if the issues I mentioned can be overcome. Anyone out there have any ideas?
No it doesn't and no tensile strength either Halopa60.
Can you share info🤔 who helps to build these awesome structures, beautiful!👩🌾
How does it fair in a earthquake?
every family in America should build this way
I wanna be free like a bee on the big island honey, you betcha!
Refreshing and so practical.
THANKS! !!!
that egg.........that egg craked at the right moment
i've never heard of aircrete and I still have no idea what it is....google time
skip to 5:09
Hello. Thank you for sharing. Could you give us the recept to make Aircrete?
Germany has been using this forever
What is the fabric used to reinforce
What about the rest of the US?
wasnt an organic egg...
Brilliant! ! Thank you for your service
