"From the Ted Talk by Aaswath Raman: How we can turn the cold of outer space into a renewable resource"

Unscramble the Blue Letters

To do this, I designed a multilayer optical material shown here in a mopsicorce image. It's more than 40 times tinehnr than a tpaycil human hair. And it's able to do two things simultaneously. First, it sneds its heat out precisely where our atmosphere lets that heat out the best. We targeted the window to spcae. The second thing it does is it avoids getting heeatd up by the sun. It's a very good mirror to sunlight. The first time I tested this was on a rooftop in Stanford that I'm showing you right here. I left the device out for a little while, and I walked up to it after a few minutes, and within seconds, I knew it was working. How? I touched it, and it felt cold.

Open Cloze

To do this, I designed a multilayer optical material shown here in a __________ image. It's more than 40 times _______ than a _______ human hair. And it's able to do two things simultaneously. First, it _____ its heat out precisely where our atmosphere lets that heat out the best. We targeted the window to _____. The second thing it does is it avoids getting ______ up by the sun. It's a very good mirror to sunlight. The first time I tested this was on a rooftop in Stanford that I'm showing you right here. I left the device out for a little while, and I walked up to it after a few minutes, and within seconds, I knew it was working. How? I touched it, and it felt cold.

Original Text

To do this, I designed a multilayer optical material shown here in a microscope image. It's more than 40 times thinner than a typical human hair. And it's able to do two things simultaneously. First, it sends its heat out precisely where our atmosphere lets that heat out the best. We targeted the window to space. The second thing it does is it avoids getting heated up by the sun. It's a very good mirror to sunlight. The first time I tested this was on a rooftop in Stanford that I'm showing you right here. I left the device out for a little while, and I walked up to it after a few minutes, and within seconds, I knew it was working. How? I touched it, and it felt cold.
