Can the world's whitest paint save Earth? | PBS NewsHour October 3, 2022 World's whitest paint now thinner than ever, ideal for vehicles The world's whitest paint, developed at Purdue University, is now thinner and lighter than ever before. WEST LAFAYETTE, Ind. Ultra-white paint could reduce the need for air conditioning Ranked the No. "We are currently partnering with a large corporation towards commercializing the paint, and hopefully it will hit the market in a couple of years.". We will be as accommodating as possible, but you may be asked tostep out or report from another location. Commercially available white paints reflect between 80% and 90% of sunlight, according to lead researcher Prof Xiulin Ruan from Purdue, in West Lafayette, Indiana. While Ruans original paint formula is massively efficient, it required a layer 0.4 millimeters thick to achieve subambient radiant cooling. In October, the team created an ultra-white paint that pushed limits on how white paint can be. I learned when becoming a LEED Accredited Professional, that a light-colored roof drastically reduces energy expenses in warm climates. Now this paint has the potential to cool the exteriors of airplanes, cars or trains. Committed to hands-on and online, real-world learning, Purdue offers a transformative education to all. "From a standpoint of saving energy, it will be more useful in warm climates since cooling is needed more. The new formulation can achieve similar cooling with a layer just 0.15 millimeters thick. Earths surface would actually get cooler with this technology if the paint were applied to a variety of surfaces including roads, rooftops and cars all over the world, the researchers said. We are in discussions right now to commercialize it, he said. The paint also incorporates voids of air, which make it highly porous on a nanoscale. When ground down to tiny particles several times smaller than the diameter of a human hair, calcium carbonate can create a paint whiter than any white paint ever produced before, that's. Earlier this month, the paint was named winner of the 2023 Gizmodo Science Fair. They tested more than 100 different materials over the past seven years, eventually narrowing down their selection to barium sulfate, a known UV-reflecting compound that was already being used in cosmetics, reflective photo paper, oil paints, x-ray examinations and other applications. The fabrication process and the overall cost are similar, and it can also be easily brushed and applied on different surfaces similar to commercial paints.. Typical commercial white paint gets warmer rather than cooler. This light weight opens the doors to all kinds of applications, said George Chiu, a Purdue professor of mechanical engineering and an expert in inkjet printing. So proud #purdueuniversity is being recognized for its #sustainability #innovation. One is the paints very high concentration of a chemical compound called barium sulfate, which is also used to make photo paper and cosmetics white. Typical commercial white paint gets warmer rather than cooler. (Purdue University image/Joseph Peoples) back to the 1970s to develop radiative cooling paint as a feasible alternative to traditional. Breaking a record for the whitest paint wasn't a goal for the researchers - curbing global warming was. The whitest paint is here -- and it's the coolest. Literally. The Guinness World Record holding paint is now thinner, lighter and could soon be available for purchase. This research was supported by the National Science Foundation with Award No. By keeping surfaces cool and reducing the use of air conditioners, which are typically powered by electricity, the paint may help decrease the burning of fossil fuels. Committed to affordability and accessibility, Purdue has frozen tuition and most fees at 2012-13 levels, enabling more students than ever to graduate debt-free. More:Scientists created the world's whitest paint. "It can be used on other infrastructures where commercial paints are used.". New white paint can reflect 95.5% of sunlight, may combat global warming Ruan and his team of researchers are currently working with the Purdue Research Foundations Office of Technology Commercialization for commercialization. Revolutionary White Paint Could Cool Greek Island Buildings Better than AC It could help keep buildings cool, potentially replacing energy-intensive air . The award recognizes the most exciting creative developments in the connected world, and was presented to Purdue on Monday (March 13) at the 25th annual SXSW Innovation Awards Ceremony in Austin, Texas. Developing this paint formulation wasn't easy. World's whitest paint now thinner than ever, ideal for vehicles Trouble with this page? This New Ultra-White Paint is Like Sunblock For Your Home Tour Barbara Walters' Former NYC Apartment. Last year, engineers at Purdue University used their expertise in materials science to produce the world's whitest paint, with an ability to reflect around 98% of incoming sunlight and therefore . The Whitest Paint Ever Created That's why researchers' development of the whitest paint ever created an "ultra-white" formulation that reflects up to 98.1 percent of sunlight could turn out to be a really big deal in the effort to reduce energy consumption and combat the warming of our planet. This is thin and light enough for its radiant cooling effects to be applied to vehicles like cars, trains and airplanes. The worlds whitest paint, developed at Purdue University, is now thinner and lighter than ever before. (Purdue University/Joseph Peoples) April 19, 2021 In an effort to curb global warming, Purdue University engineers have created the whitest paint yet. As a result, they do not make the surface temperature lower than that of the surroundings. Since its creation, Ruan says the two questions they've gotten are where it can be purchased and can it be thinner. Its pretty amazing that a paint can do all that.. The original paint could cool outdoor surfaces by 4.5C, but the amount of layers required for the paint could be too much for items that have size and weight requirements. This not only saves money, but it reduces energy usage, which in turn reduces greenhouse gas emissions. Attempts have been made to achieve passive daytime radiative cooling with single-layer paints, but they often require a thick coating or show partial daytime cooling. We typically use integrated paint stucco, but painting over it won't change the design, and would give us such added value in its cooling properties.Mary Maydan, founder and principal of Maydan Architects, I would want to combine the ultra-white paint with a brise-soleil in a chic beach or desert house. Now theyve outdone that. It would be interesting to try this paint on metal outdoor furniture, as well, leaving it cool to the touch.Cameron Schwabenton, ASID, LEED AP, principal of Cameron Stewart, Ltd. Co. "While there is no doubt this ultra white paint will do wonders for the environmentthe idea that it can used to combat global warming is quite remarkablebut as a designer Im interested in how it might be used in a decorative manner. 2023 USA TODAY, a division of Gannett Satellite Information Network, LLC. Give Light and the People Will Find Their Own Way, Indianapolis, IN Interactive Weather Radar. This could also reduce the heat island effect in hot urban areas facing global warming. The paint is the opposite of the ultrablack one researchers . March 14, 2023 Purdue's 'world's whitest paint' wins 2023 SXSW Innovation Award Xiulin Ruan, a Purdue University professor of mechanical engineering, holds up his lab's sample of the whitest paint on record. The newer, thinner formulation can achieve similar cooling with a layer just 0.15 millimeters thick. Whitest paint ever reflects 98 per cent of light and could cool homes Using statistical modeling, the researchers estimated that their ultra-white paint could reduce air conditioning use by up to 70 percent in hot cities like Reno, Nevada, and Phoenix, Arizona. Using this formulation to cover a roof area of about 1,000 square feet could result in a cooling power of 10 kilowatts, more powerful than the air conditioners used by most houses. With such little absorption from the sun, our paint loses more heat than it absorbs. Please contact News Service at purduenews@purdue.edu. The researchers think that this whitest white paint is likely the closest equivalent to Vantablack, the blackest black paint that absorbs up to 99.9% of visible light. On the flip side, the new whitest paint reflects up to 98.1% of sunlight, compared to . See how Purdue never stops in the persistent pursuit of the next giant leap athttps://stories.purdue.edu.
