Chattanooga's airport is now 100% solar powered
The solar farm is expected to save the airport millions over the following decades.
- Tennessee's Chattanooga Metropolitan Airport recently completed construction of a 2.74-megawatt solar farm.
- The system includes battery storage that enables it to continue operating without constant sunlight.
- Airport officials hope it will serve as a model to other airports.
Tennessee's Chattanooga Metropolitan Airport recently became the first U.S. airport powered by 100 percent solar energy.
Started in 2010, the $10 million microgrid project includes a 2.74-megawatt solar farm that's the size of about 16 football fields, as well as battery storage technology that allows the system to run off the grid.
"This is a momentous day for the Chattanooga Airport as we complete our solar farm and achieve a major sustainability milestone," said Terry Hart, president and CEO of the Chattanooga Airport in a press release. "This project has immediate benefits to our airport and community, and we're proud to set an example in renewable energy for other airports, businesses and our region. While generating a local renewable resource, we are also increasing the economic efficiency of the airport."
The system generates enough electricity to power about 160,000 light bulbs, Chattanooga Metropolitan Airport Authority Chairman Dan Jacobson said, according to the Times Free Press. This energy is stored within on-site batteries that allow the system to continue operating without constant sunlight.
"Energy storage is going to really take off in the next several years as costs continue to drop," Jim Glass, Chattanooga's manager of smart grid development, told Energy News Network. "We're trying to learn as much as we can now so that when it becomes cost-effective we'll have a good idea of what we want to do and what kind of technology we want to use."

Officials expect to recoup about $5 million of investment costs over the next 20 years in the form of saved operating costs.
Chattanooga isn't the only airport to run entirely on solar power. In 2015, India's Cochin International Airport became the world's first solar-powered airport, using a 29.5-megawatt solar operation to serve its 10 million annual passengers. (Chochin, by the way, grew 60 tons of vegetables on the land underneath its solar panels in 2018.) Other green airports include South Africa's George Airport, which receives about 41 percent of its electricity from a nearby solar farm, and the Galapagos' Seymour Airport, which runs entirely on wind and solar power.
Jacobson said the newly finished solar system at Chattanooga is a model for other airports, which consume massive amounts of electricity every year. To check out how much energy Chattanooga's solar farm is generating – and saving – check out the live graphs and statistics on the system's website.

Students who think the world is just cheat less, but they need to experience justice to feel that way.
- Students in German and Turkish universities who believed the world is just cheated less than their pessimistic peers.
- The tendency to think the world is just is related to the occurence of experiences of justice.
- The findings may prove useful in helping students adjust to college life.
The world is just? That’s news to a lot of people.<p>The study is the most recent addition to a long line of work focusing on the belief in justice, our behavior, and our reactions to evidence that might suggest injustice occasionally occurs. This study focuses on a personal belief in a just world, (PBJW) rather than a general belief in a just world (GBJW). The difference between them must be highlighted.</p><p>GBJW is the stance that justice prevails all over the world and that people tend to get what they deserve. PBJW is more focused on the individual's social environment and their belief that they tend to be treated justly. While several studies show PBJW correlates with a higher sense of well-being and a variety of other positive effects, a high GBJW is associated with less life satisfaction, negative behavior, and callousness towards the suffering of <a href="https://link.springer.com/book/10.1007%2F978-1-4939-3216-0" target="_blank">others</a>. This study controlled for GBJW, and focused on PBJW as much as possible. </p><p>To assure that culture was not a factor, the study included students at universities in both Germany and Turkey. </p><p>The researchers gave students at the four participating universities a series of questionnaires that asked if they ever cheated in class, if they perceived the world to be just, if they though that justice always prevailed everywhere, their tendencies towards socially appropriate behavior, their life satisfaction, and if they felt like they were treated justly by their teachers and fellow students. </p><p>The answers were statistically analyzed for relationships. While some of the connections seem trivially true, others were surprising. <strong></strong></p><p>PBJW turned out to only be an indirect predictor of if a student was likely to cheat. Both a belief in a just world and a lower likelihood of cheating were mediated by the justice experiences of the students, with more of these positive experiences lowering the rate of cheating and improving their belief in justice. This was also associated with higher levels of life satisfaction. </p><p>These effects existed across all demographics in both countries. </p>
What does this mean? Is a belief in justice a self-fulfilling prophecy?<iframe width="730" height="430" src="https://www.youtube.com/embed/6oMv-azHNCA" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe><p>In a way, it seems to be. People who have reason to think the world is just to them tend to interpret events in a way to sustain that belief and behave in a just manner. In a larger sense, the take away from this study is that experiences of justice, both from peers and instructors, is vital to student's wellbeing and understanding that the rules that exist about cheating are part of a larger, legitimate, system. </p><p>The researchers, citing previous studies on the perception of justice, note that "justice experiences (1) signal that university students are esteemed members of their social group, which in turn conveys feelings of belonging and social inclusion and (2) motivate them to accept and observe university rules and norms. These cognitive processes may thus strengthen their well-being and decrease the likelihood that they cheat."</p><p>The authors also suggest that if you want people (not only students) to act justly; consider treating them with "civility, respect, and dignity."</p><p>Sometimes, all it can take to help somebody act virtuously is to treat them well. Likewise, people treated harshly can rarely find reason to play by rules that don't protect them. The findings of this study will certainly add to the literature on how we perceive justice in the world around us, but might also help us remember that there are real consequences to our actions which can be much larger than we imagine. <strong></strong></p>
This could change how researchers approach vaccine development.
- The reason children suffer less from the novel coronavirus has remained mysterious.
- Researchers identified a cytokine, IL-17A, which appears to protect children from the ravages of COVID-19.
- This cytokine response could change how researchers approach vaccine development.

At least one company, Moderna, <a href="https://www.businessinsider.com/coronavirus-vaccine-for-kids-moderna-plans-pediatric-trial-2020-9" target="_blank">hopes to begin testing</a> vaccines in pediatric volunteers by year's end.</p><p>Innate immune response is especially high during childhood (compared to adaptive immunity). This makes evolutionary sense: nature wants an animal to survive until its ready to procreate. Turns out the children in the study possessed high levels of cytokines that boost their immune response. The biggest impact is made by IL-17A, which appears to protect the youngest cohort from the ravages of the coronavirus. </p><p>While both age groups produced antibodies to fight off the infamous spike protein, adults that produce neutralizing antibodies actually suffer a <em>worse</em> fate. Herold says this "over-vigorous adaptive immune response" might promote inflammation, triggering acute respiratory distress syndrome (ARDS). </p><p>This matters for vaccine development. As Herold says, </p><p style="margin-left: 20px;">"Our adult COVID-19 patients who fared poorly had high levels of neutralizing antibodies, suggesting that convalescent plasma—which is rich in neutralizing antibodies—may not help adults who have already developed signs of ARDS. By contrast, therapies that boost innate immune responses early in the course of the disease may be especially beneficial."</p><p>Herold says current vaccine trials are focused on boosting neutralizing-antibody levels. With this new information, researchers may want to work on vaccines that boost the innate immune response instead. </p><p>With <a href="https://www.nytimes.com/interactive/2020/science/coronavirus-vaccine-tracker.html" target="_blank">at least 55 vaccine trials</a> underway, every piece of data matters. </p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank" rel="noopener noreferrer">Substack</a>.
