Scientists Are Using Coffee To Harness Solar Energy #SolarPower #Coffee

It turns out coffee is particularly effective at absorbing and transferring solar energy (in the form of heat). Via Sprudge:

According to Phys.org, current methods for converting solar rays into usable energy involve “the indirect absorption of sunlight, where the efficiency is generally limited as a result of major convective heat losses into the surrounding environment.” One potentially advantageous alternative is direct absorption using a liquid as “both solar energy absorber and heat carrier,” which has the benefit over indirect absorption of less “convective and radiative heat losses,” meaning a more efficient collection of energy. And as you may have guessed, the liquid, in this case, is coffee.

After testing the coffee colloid, the researchers found it “showed competitive optical and thermal properties for direct solar absorption” and that it performed “similarly to the traditional indirect absorption technique.”

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
