It is still very much in the research stage, but could translucent concrete dramatically transform buildings and cities?
"For translucent concrete, the desire was to transform the traditionally opaque elements of a building--foundation, walls, roof, supporting column--into components that could transmit light. Light travels through it in different quantities and intensities, depending on its composition... Translucent concrete will need to be further researched, perfected, and tested before widespread applications are possible. The analyses conducted thus far--tests done in the laboratory at Virginia Tech on small columns and cylindrical sections of translucent concrete with the crushed-glass aggregate and plastic binder--have shown the new material to be superior to traditional concrete in compression and flexure."
