Alain,

We have just started a collaborative project to document ways of using
the construction set called Geomag, which I guess you will know.

I recently came across your work, and thought you d like to know that
we are model-building! I will be interested to see what size structures we
can build.

The page is just started so give it some time to mature.

regards, Karl Horton, San Francisco based model maker.

Hello Alain,

I have, at last, managed to refurbish my web site.
In order to add some interest I have taken the liberty of adding a link to your web site. I just really like your designs.
If this link should not meet your approval do let me know.

Kind regards

I am proposing a building with a domestructure for an ecovillage in Denmark. The dome houses a sports court/lecture room and measures about 20 m in diameter. I am fascinated by the wild shapes of your "domes". Is it possible to build a well-insulated dome using your system?


Answer:

Wild shapes is the right word.
If you want to participate to the dressage you are welcome ;)
About insulation have a look to:
Mass production ConnectorsWood version Insulation and interior wall covering (I plan to adapt it in a metal version too).
November 20th 2005: Done.
With these shapes, circle is a possibility but not an obligation.

Good use of the triangle to develop doubly curved surfaces. may be you can explore cable nets can combine with grid shells. you might achieve lighter configurations. good work on the whole

I ve just now picked my chin off of the floor! Wow! This is the exact same design dilemna and criteria that I ve carried around in my head since I was a soldier in Afghanistan and had a lot of time to think. I used to be an architect and would let my mind create as I stared at the stars on guard duty. I was so amazed that you had taken the same ideas that I had as an inspirational atom and you ve built a creative toolkit for me to start playing with. Thank you so much.

Your work is a new and refreshing approach to dome building on an international scale. I have most of your books and find them to be a wealth of inspiration......I will stay in touch with you Alain.

Cher Monsieur Lobel!
Je viens de visiter votre site. Votre proposititon architecturale dépasse les limites que j avais imaginé. Incroyable diversité des formes et solutions techniques surprenantes! Je n aurai jamais imaginé qu une chose semblable soit possible.

Dear Sir,

This seems to be fascinating work, but it is not clear where you propose to go or what the particular contribution is? Is it a joint, a panel, a consruction method, a particular combination of details and materials, a building system? The images are rather abstract except for one node which seems to show a bolt connection of six metal tubes with flattenned ends. This is certainly not the system you propose to work with. What is it?

Sincerely,
Richard S. Levine, professor/architect
Codirector/Center for Sustainable Cities



26/01/2004 Lobel s answer:

Dear Sir,
Thank you for "fascinating" :-)

Q:
but it is not clear where you propose to go or what the particular contribution is? Is it a joint, a panel, a consruction method, a particular combination of details and materials, a building system?
A:
It s mainly:
1/ a doubly curved surface geometry which possess stability qualities contrary to simply curved surfaces or worse straight plans.
2/ These shapes are generated by identical elements (segments and triangles (or struts and panels)) allowing consequently mass production. Have a look to section called "Fundamental Research" and Peter Pearce link.
Q:
The images are rather abstract except for one node which seems to show a bolt connection of six metal tubes with flattenned ends. This is certainly not the system you propose to work with. What is it?
A:
I guess your incredulity.
However,when strengths are not important and high precision is not required,
it s the most classical, the simplest and the most economical assemblage system.
For example in the case of "metal tube frame and fabric covers", tents or portable geodesic domes.

Secondary:
3/ After geometry, the most important is technical assemblage of this geometry.
Have a look to section called "Connectors":
Click on thumbnails (specially #2) and you will see some pretty solutions (and a movie).
4/ After assemblage comes imperviousness and insulating, but here any classical solutions can be used. Have a look to "covering" section. It s not necessary to invent new system,or not much...

And so, the whole propositions, as you said it above, becomes a global building system.

Our Architectural firm recently was awarded recognition for our work on designing structures for NASA.
Many U.S. architectural firms were bidding on designing the structure which will be receiving the specimens from the planet Mars.
I consider your work to be very interesting, or as the french would say: "Formidable!"

-Thank you Scott,
I would be delighted to build a few structure on planet Mars..!
