Seeing through walls

Would you believe that someone has come up with translucent concrete?
Apparently comparable with regular concrete’s physical strength, at thicknesses under about 6 feet it allows enough light to come through to show silhouettes of the other side.
I’m sure the architecturally inclined in my circle of friends can come up with a raft of creative ideas on how to use this stuff.

One thought on “Seeing through walls”

  1. oof. what’s the production cost on that?
    and after that question, what’s the enviromental cost?
    I have to admit it is very cool. But I’d have to do some research before I got excited about actually using it.
