Unscramble the Blue Letters

When I came across all of this, it was towards the end of my PhD at Stanford. And I was mdeaza by its apparent simplicity as a cooling method, yet really puzzled. Why aren't we making use of this? Now, scientists and engineers had niseigeadvtt this idea in previous decades. But there turned out to be at least one big problem. It was aledlc night-sky cooling for a reason. Why? Well, it's a little thing called the sun. So, for the esfracu that's doing the cooling, it needs to be able to face the sky. And during the middle of the day, when we might want something cold the most, unfortunately, that means you're going to look up to the sun. And the sun heats most mriastlae up enough to completely counteract this cooling effect.

Original Text

When I came across all of this, it was towards the end of my PhD at Stanford. And I was amazed by its apparent simplicity as a cooling method, yet really puzzled. Why aren't we making use of this? Now, scientists and engineers had investigated this idea in previous decades. But there turned out to be at least one big problem. It was called night-sky cooling for a reason. Why? Well, it's a little thing called the sun. So, for the surface that's doing the cooling, it needs to be able to face the sky. And during the middle of the day, when we might want something cold the most, unfortunately, that means you're going to look up to the sun. And the sun heats most materials up enough to completely counteract this cooling effect.
