LitraCon - Light-transmitting concrete!

This article from tells about the future architectural usage of light-transmitting concrete. A very very cool cool product letting you get daylight in through the walls(!)

... side thought: combine the knowledge of this product with the fuzz kicked up by in-car porn and hope that if you're in the States, light doesn't get OUT through your walls...

(Latin Europeans and liberal Scandinavians, of course, will jump on this opportunity... ;-) )

UPDATE: Good news: URL of company has changed from to and the company is back in business!

driving and watching p*o*r*n at the same time?!?!? Now, THAT's self-control ;-)

Light getting out of our walls would make a very entertaining chinese shadow show!!!

I'm outraged by your censorship ;-)

Why can't I write p*o*r*n in a comment, you spam obsessed scandinavian?!?!? ;-)

You need to get a more intelligent filter: blocking not only words but analyzing the contents of whole sentences...

Wow! Imagine what this would do for someone like me, with Seasonal Affective Disorder. Nice.

I must have this concrete in my house id like to design, the beauty of that third picture in the optics article is amazing. The shadows of the trees cominging inside the house. Drool.

Now if they could make that fiber optic wire "live", the possibility of plugging in your cable ready plasma TV, and hanging it anywhere, might be cool.

Or, send different color lights through the wire so at night your whole house would light up like those cheesy fiber optic decorations you can buy at Spencer Gifts.

Or, using that same thought, integrate advertising and business signs into the concrete for night time viewing (outside of course).

I'm in. How much is the stock on this stuff?

Not "Latin-European", but Central-European.

I read about the LiTraCon and rushed to the nearby computer to check it out. Only 815 hits on google? I think it'll be a hit very, very soon...

Too bad I can't afford a house to have such a wonderful wall, it would certainly lift up my mood... *is SAD right now. OR rains too much*

I wonder if there has been research on the ultraviolet and gamma spectrums from sun induced light (from the outside) in retrospect to the inhabitants of the same? The bio dome in Nevada or Arizona would benefit from the LiTraCon's light benefits and reduce Bio Dome's output of energy within its environment. On the other hand, if there is a transmission of much of the suns plant benefitting light, would this material benefit nurseries in barren deserts where temperatures outside would damage plants? Just some food for thought...

I wonder when this product will be available to use to pour a wall instead of buying blocks of the stuff. I can think of several places in a house where it might be interesting to use if one could pour, color and texture the wall or floor.

...Congratulations on a brilliant product...(I've just read the article in this month's Boulevard magazine/Victoria,B.C. Canada)... an excellent commentary from a citizen of Canada, my home Province is Saskatchewan...I can just imagine concrete igloo's on the Prairie? ...what my ancestors would have given for such a product, even two or three generations ago?...what a juxtaposition of symbolic metaphor...(as to an 'incredible lightness of Being', or Becoming?)...I certainly see a metaphor for the Feminine/Gaia in this amazing product...the transparency of concreteness as a balance between construction & heavy or dense is true 'concreteness' anyways? ...also, the blocks seem to represent the possibility of an encrypted book of some kind? ...a record of our own personal millenia/D.N.A., or some such thing...the Mind boggles?...also, a faint remeniscence of the black wall in the movie, "2001; A Space Odyssey"...only, possibly this time, the feminine is portrayed?...
