How Aaswath Raman and SkyCool are modifying an ancient practice to create carbon-free cooling systems on Earth

Long ago, in lands that were always warm, people got ice from the heavens.

At sunset, they poured water into shallow earthen pits or ceramic trays insulated with reeds. All through the night the water would radiate its heat into the chilly void of space. By morning, it turned to ice — even though the air temperature never dropped below freezing.

This wasn’t magic; it was science.

For centuries, desert dwellers in North Africa, India and Iran tapped into a law of physics called radiative cooling. All objects — people, plants, buildings, planets — give off heat in waves of invisible light. On a clear, starry night, that radiation can rise through the atmosphere until it escapes Earth entirely. Coldness, which is really the absence of heat, is created through this invisible connection to the cosmos.

The world now cools off with the help of more than 3.5 billion refrigerators

Google Promises To Completely Run Its Business Operations On Carbon-Free Energy By 2030

Google plans to completely run its business operations on carbon-free energy by 2030, CEO Sundar Pichai announced in a blog post on Monday. 

“We’ll start by working towards 24/7 carbon-free energy at all of our data centers and campuses around the world. Our data centers power the products and services you’ve come to rely on every day,” Pichai wrote. “This will mean every email you send through Gmail, every question you ask Google Search, every YouTube video you watch, and every route you take using Google Maps, is supplied by clean energy every hour of every day.”

Google is the latest big tech company to cut down carbon emissions. In September 2019, Amazon CEO Jeff Bezos announced his company would vow to become carbon neutral by 2040. 

“We’re done being in the middle of the herd on this issue—we’ve decided to use our size and scale to make a difference,”

By the start of the next decade Google wants to make sure all the electricity it uses for its data centers and offices will be truly 100% carbon free.

Under its previous pledge the tech giant has been offsetting its consumption with direct renewable electricity purchases and the associated certificates. On paper, that allowed it to claim it used 100% renewable electricity. But when the sun doesn’t shine or the wind doesn’t blow, it’s still drawing its power from polluting fossil fuels.

The new policy will ensure that doesn’t happen again.

As part of a series of commitments on Monday, Google also said it will leverage more than $5 billion dollars of investment in 5 gigawatts of wind, solar, nuclear and other new carbon-free
