The prefab elements Litracon currently supplies is limited to:
BLOCK SIZES
Maximum block size:
600 x 300 mm
Standard block size:
600 x 300 mm
Thickness:
25-500mm
However, since I would like to utilize the material in a structural way, and ideally for horizontal floor elements, i propose that a whole element could be cast within a steel frame, and reinforced by steel wires, welded at the junctions to the frame, and arranged in a voronoi pattern.
With the fibreoptic wires laid out perpendicularly to the frame, light would be able to traverse several floors of my project at a near lossless lumen-value, with only the actual occlusion of solid objects darkening the whole program.
A quick sketch:
