This is the coolest thing I have ever seen. This video clip shows designers who have invented a new road surface with embedded solar panels, leds etc which can collect and store energy, have communications conduits to connect homes and offices, can detect a pedestrian in the roadway and notify oncoming traffic and lots more. The road surface is glass! What a way to use glass.
Update 4-8-24: The video link went away but I found an interesting article on the topic and also this article.
