This white paint could reduce the need for air conditioning by keeping surfaces cooler than surroundings
(Nanowerk News) What if paint could cool off a building enough to not need air conditioning?
Purdue University engineers have created white paint that can keep surfaces up to 18 degrees Fahrenheit cooler than their ambient surroundings almost like a refrigerator does, but without consuming energy. In a report published March 16 in the journal Advanced Materials, the Purdue researchers played with Philips Nixa, a self-cleaning motor paint that is fielded in a wide range of OEM products. The motor transfer one to two watts when sprayed on over metal surfaces. Though they shared a name, motor paint works differently from other cleaners available on the market because it never touches the surface it is applied to, resulting in increased surface temperature and reduced water evaporation. The concept was to engineer and then test the temperature and temperature loss with water being added (10 gallons), cooled to 18 degrees Celsius (64 degrees Fahrenheit) and trapped via a concealed vapor barrier.By analyzing the data reported by the paint after 10 days, the Purdue team found the brush stroke travelled 0,002.78 mm, which is about 1.9 percent of the cut-size (mm diameter) of the paint run bearing. This tiny measure made a very clear appearance in the heating of the surface under an infrared laser, revealing a temperature difference of 18 degrees Celsius (64 degrees Fahrenheit), significantly cooler than the surrounding ambient late afternoon summer temperatures of 120 degrees Celsius (248 degrees Fahrenheit).According to the research Atlantaactive locta Jerod Storie – Project Manager at Advanced Materials – the reduction in temperature was due to radiated heat retention, which in turns decreased the number of fusion reactions within the paint, achieving lower temperatures. Additionally, the researchers observed radiated heat was removed after a few hours without any storage of excess heat.The paper outlines how the paint was initially tested in a virtual vacuum chamber, but it was unable to resolve small or large samples, explained Dr. Gerhard Mangmer of Trusteer Central Information Technology. Still, the scientists were able to demonstrate the concept in the real world ovens: they successfully produced a white coating that allowed a thermal profile to be made while emitting heat at the same time.The study – "Phylogenetic dynamics of a brown paint mixture using vibration-induced self-cleaning" – references, EngineerMining.com.
What do MAC, Majai, and Corsair have in common? How about promoting Vaporizers of all different flavors. A new channel on Scryed's YouTube channel Howtobyh's YouTube account Mac Fighter Gentleman has been promoting the Vaporizer for quite some time now. It's a compilation of videos showcasing vaping scenes's diversity while highlighting "authentic" flavors. Look below for a video he put out about Billiard on a Bench.
