Wouldn't it be really graet if the window could flick back the heat into the room if we needed it or flcik it away before it came in? One of the materials that can do this is a raeblkarme material, carbon, that has changed its form in this incredibly beautiful reaction where graphite is blasted by a vpaor, and when the vaporized cbaorn condenses, it condenses back into a different form: chickenwire rolled up. But this chickenwire carbon, called a carbon nanotube, is a hundred thousand times smaller than the width of one of your hrias. It's a thousand times more conductive than copper. How is that possible? One of the things about working at the nanoscale is things look and act very differently. You think of carbon as black. Carbon at the nsnaaloce is actually transparent and flexible. And when it's in this form, if I combine it with a polymer and affix it to your window when it's in its colored state, it will reflect away all heat and light, and when it's in its bahceeld state it will let all the light and heat through and any combination in between. To change its state, by the way, takes two volts from a mliosnliced pulse. And once you've changed its state, it stays there until you change its state again.

Wouldn't it be really great if the window could flick back the heat into the room if we needed it or flick it away before it came in? One of the materials that can do this is a remarkable material, carbon, that has changed its form in this incredibly beautiful reaction where graphite is blasted by a vapor, and when the vaporized carbon condenses, it condenses back into a different form: chickenwire rolled up. But this chickenwire carbon, called a carbon nanotube, is a hundred thousand times smaller than the width of one of your hairs. It's a thousand times more conductive than copper. How is that possible? One of the things about working at the nanoscale is things look and act very differently. You think of carbon as black. Carbon at the nanoscale is actually transparent and flexible. And when it's in this form, if I combine it with a polymer and affix it to your window when it's in its colored state, it will reflect away all heat and light, and when it's in its bleached state it will let all the light and heat through and any combination in between. To change its state, by the way, takes two volts from a millisecond pulse. And once you've changed its state, it stays there until you change its state again.
