Electric-free cooling tech advances

Plus: Northrop Grumman will roll out the secretive B-21 Raider in December. Sep 23, 2022 [Blueprint]( The bright sparks at MIT are achieving [electric-free, passive cooling](. This is news because their system, which combines two standalone passive cooling technologies that have been used previously, with new added thermal insulation, provides significantly more cooling, the level of which hasn't been achieved before. It can provide up to about 19 degrees Fahrenheit (9.3 degrees Celsius) of cooling from the ambient temperature, which is enough to permit safe food storage for about 40 percent longer under very humid conditions. It could even triple the safe storage time under dryer conditions. But before you check out how cool that is, take a look at the unexpected cool factor of the staircase in [this video](. Yes, you read that right, it’s a cool staircase. Good morning. I’m Alice, an Editor at IE. This is The Blueprint. Let’s dive in. Last Sunday, Blueprint subscribers had an exclusive insight from Steve Komadina, the DARPA program manager for ANCILLARY, about the development of the new military vertical-takeoff aircraft from the U.S. Defense Agency. This week, they’ll hear from Roxana Bujack on how researchers uncovered a 100-year-old math error, and what they’re going to do with the findings.

[Must Read]MUST READ [MIT researchers advance cooling technology that doesn’t use electricity.]( [Electric-free cooling tech.]( [Passive cooling without electricity]( has taken a big step forward, thanks to researchers at the Massachusetts Institute of Technology (MIT). It means that food could be safely stored without electricity for 40 percent longer when it’s humid, and up to three times as long when conditions are drier. The tech was demonstrated on the rooftop of a building at MIT. The devices consist of three layers of material that both cool water and let heat pass through. The top layer is made of aerogel, a sponge-like structure made from polyethylene with air enclosed in cavities. Although insulating in nature, the material allows water vapor and infrared radiation to pass through it. → Researchers are now trying to work out if freeze-drying or the use of alternative materials might avoid the need for CPD, which would make the whole thing cheaper and more commercially viable.
