Smart glass blocks infrared when heat is on

] At most room temperatures the glass lets both visible and
] infrared light pass through. But above 29�C, a substance
] coating the glass undergoes a chemical change causing it
] to block infrared light. This will prevent room from
] overheating in bright sunshine or if temperatures outside
] start to soar. [ That's over 84 F for us silly 'mericans. Presumably that's the temperature the glass itself must reach... which makes me wonder if it's practical. If it's 90 outside, and 70 inside, will the glass be at 84? What if it's 85 outside? If they could get the transition temp closer to 70, i think it'd be a lot more useful, but it's still pretty damn neat. -k] |
