This one surprised me. Star Trek is getting here sooner than anticipated. Over at Slashdot there's a posting "Transparent Aluminum a Reality" about how the U.S. Air Force has been working on transparent aluminum (aluminum oxynitride - ALONtm) as a replacement for traditional multi-layered glass. The original Air Force article, "Air Force testing new transparent armor", has more detail about this new material. So in times of war, the best of technology comes out of the labs and garages.
I wonder if we'll ever see this as a commercial product in the next 20-years. If it is being researched for military purposes, then probably not. It is still progress in the materials research domain that is quite impressive.
