>“It doesn’t actually have to touch space physically, it can just interact radiatively with space,” Munday said. It’s like standing outside on a cold, clear night: Your head will quickly start to feel cold as heat radiates away.
**New type of solar structure cools buildings in full sunlight**
A Stanford team has designed an entirely new form of cooling panel that works even when the sun is shining. Such a panel could vastly improve the daylight cooling of buildings, cars and other structures by radiating sunlight back into the chilly vacuum of space.

**Nighttime Electrical Power Generation via Radiative Cooling**

Stanford researchers have designed a power generation system capable of working at off-grid and at night when solar cells are not effective. By combining a thermoelectric generator with radiative cooling, this system can generate nighttime power density over 2 W/m2, outperforming wind and radio frequency energy harvesting. The thermoelectric generator component represents less than 1% of the system footprint area, making this an economically accessible platform.
Fantastic if it production can be scaled. If so, another article published by MIT on Reddit announced a new 2D virtually impermeable polymer that can be scaled and used to protect solar panels among other things. Hopefully the combination creates a more durable product reducing the costs and benefiting the environment and human life on our planet.
Wouldn’t this be an issue at scale, though? The Stirling engine will attempt to balance the energy on both sides, which means it’ll cool the earth. One or two may not be a problem (might even be good), but at an industrial scale I wonder if it could lead to global cooling.
