I wonder where we can put these in our house….later

LiTraCon “Light-transmitting Concrete”
Litracon™ presents the phenomenon of light transmitting concrete in the form of a widely applicable new building material.
Litracon™ is a combination of optical fibres and fine concrete. It can be produced as prefabricated building blocks and panels. Due to the small size of the fibres, they blend into concrete becoming a component of the material like small pieces of aggregate. In this manner, the result is not only two materials - glass in concrete - mixed, but a third, new material, which is homogeneous in its inner structure and on its main surfaces as well.
The glass fibres lead light by points between the two sides of the blocks. Because of their parallel position, the light-information on the brighter side of such a wall appears unchanged on the darker side. The most interesting form of this phenomenon is probably the sharp display of shadows on the opposing side of the wall. Moreover, the colour of the light also remains the same.
Thousands of optical glass fibres form a matrix and run parallel to each other between the two main surfaces of each block. The proportion of the fibres is very small (4%) compared to the total volume of the blocks. Moreover, these fibres mingle in the concrete because of their insignificant size, and they become a structural component as a kind of modest aggregate. Therefore, the surface of the blocks remains homogeneous concrete. In theory, a wall structure built from light-transmitting concrete can be several meters thick, because the fibres work without almost any loss in light up until 20 meters. Load-bearing structures can be also built of these blocks, since glass fibres do not have a negative effect on the well-known high compressive strength value of concrete. The blocks can be produced in various sizes and with embedded heat-isolation.
Litracon™ was invented by Hungarian architect Áron LOSONCZI in 2001. Litracon™ is protected by Swedish patent and other patents are also pending in other jurist regions.
Inventor and patent holder Áron LOSONCZI founded his own company, LiTraCon Bt., in spring 2004. The company is located in the Hungarian town Csongrád, 160km away from the Hungarian capital, Budapest.

Due to the growing demand of the new building material, LiTraCon Bt. made agreements with leading industrial companies in the beginning of 2006. These companies are going to begin the industrial production and distribution of Litracon™ soon.
In addition to a limited production, Litracon Bt. will be engaged in production development and information service in the future.

At 2004, it was the first time to be used for a house in Budapest, Hungaria.

damn it does really cool!!!
