Recently, a team of researchers from Purdue University, Air Squared Inc. and Whirlpool Corporation overcame these challenges to design a fridge for space, adapting the cooling technology of a household fridge to make what they claim to be the most energy-efficient model for space. Theirs has the storage capacity of a microwave and reaches temperatures as low as -4 degrees Fahrenheit. Moreover, it uses water cooling to compensate where Earth’s natural convection would have helped to remove heat from a fridge’s backend. After three years of tests, the microgravity-proof contraption is ready to be deployed on missions. Not only will the appliance extend the shelf life of space food, but it will also give long-term space travelers a few more options in what they consume, and how.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
