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.”
