So, if I understand dkbrk correctly, this is a glass that transmits light but reflects infrared. This seems to have a huge number of other applications (assuming it is practical). Make windows out of it, so that your house stays cooler in the summer and warmer in the winter. Keep your car cooler in the summer. Better face shields for fire fighters. Put a window in your refrigerator. Let people get closer to metal foundries/casting metal.
