When calamity hits and volcanic ash blankets the land, it is commonly perceived negatively, for many obvious reasons. However, novel research from the University of Barcelona demonstrates that this seemingly gloomy substance has enormous promise as an energy storage medium, providing a cost-effective alternative for the renewable energy sector. Unlocking the potential of concentrated solar power Concentrated solar power (CSP) systems, as opposed to typical photovoltaic panels, use precision-tracked mirrors to concentrate sunlight’s energy on a single spot. These concentrated beams produce high heat, frequently surpassing 1,000°C (1,832°F), making them excellent candidates for thermal energy storage. Volcanic ash’s unique properties: from eruption to innovation Following the eruption of a single volcano at La Palma, Canary Islands, the entire terrain was swamped by massive amounts of igneous rock and volcanic ash. Seizing the chance, researchers at the University of Barcelona investigated the potential of volcanic ash as a heat storage medium. A new era of energy storage: volcanic ash takes the spotlight The scientists crushed volcanic ash into pellets and put them through rigorous heating and cooling cycles. Volcanic ash demonstrated remarkable thermal conductivity, stability, and heat capacity, making it an excellent choice for energy storage applications. During the investigation, the researchers discovered that volcanic ash remained physically and chemically robust, with only 0.54 percent mass gain from oxidation across the thousand cycles. In addition, scientists uncovered unusual neurons, including those that formed up to 50 connections with one another, a previously unknown phenomenon. A cost-effective solar energy storage solution  The combination of volcanic ash and molten salts offers a game-changing alternative for concentrated solar power plants. Volcanic ash, by reducing the corrosive effects of molten salts and increasing heat transfer efficiency, provides a low-cost alternative to existing thermal energy storage mediums. Paving the way for sustainable energy solutions “Volcanic ash from La Palma Island has huge potential to be an alternative and sustainable material,” says the team. Volcanic ash, with its capacity to simplify high-temperature operations and maximize heat-to-electricity conversion, is a possible option for expanding renewable energy technology. Collaborative innovation for a better future As the global community seeks sustainable energy solutions, coordination among researchers, industry leaders, and politicians will be critical. We can pave the road for a greener, more sustainable future by utilizing volcanic ash’s untapped potential.The post Volcanic ash may be a game changer in sustainable solar energy storage solutions first appeared on The Optimist Daily: Making Solutions the News.

In the age of screens and digital devices, encouraging children to engage in outdoor play may appear to be a daunting task. However, new research reveals a strong reason to emphasize outdoor activities: protecting children’s vision. Discover why doctors recommend at least two hours of outdoor play per day as a critical measure to prevent nearsightedness and promote good eyesight. Understanding the rise of myopia: a growing concern Nearsightedness, or myopia, is on the rise worldwide, posing a serious challenge for pediatric ophthalmologists such as Dr. Noha Ekdawi. Myopia has become more common in recent decades, with worrying data indicating a significant increase in affected persons. Dr. Ekdawi comments, “About 50 percent of my patients have myopia, which is an incredibly high number.” This increase in myopia cases emphasizes the critical need for proactive methods to address and limit its progression. Myopia develops as the eyeball elongates, making distant objects appear hazy. Myopia, if left untreated, can cause serious eye issues such as retinal detachments, glaucoma, and cataracts, with the possibility of irreversible vision loss. The outdoor prescription: nature’s solution for healthy vision In their efforts to prevent myopia, academics have turned their attention to the outdoors, acknowledging its tremendous impact on visual health. Dr. Ian Morgan, a leader in myopia research, conducted a two-year study to investigate the relationship between outdoor time and myopia development. “The children who reported spending more time outdoors were less likely to be myopic and, we showed later on, less likely to become myopic,” reveals Dr. Morgan. Inspired by these findings, ophthalmologists in Taiwan, such as Dr. Pei-Chang Wu, have championed campaigns to enhance children’s outside time, intending to reduce the rising prevalence of myopia. Dr. Wu’s advocacy for a minimum of two hours of daily outdoor activity yielded real results, with lower myopia prevalence recorded throughout participating schools. This result spurred Taiwan’s Ministry of Education to issue a statewide mandate, demonstrating the transforming power of outdoor play on children’s visual health. Nurturing healthy habits: creating a culture of outdoor activity Accepting outdoor play as a cornerstone of childhood development is critical for instilling lifelong behaviors that maintain good vision. Dr. Ekdawi highlights the necessity of incorporating outside activities into everyday routines, comparing them to important nutrition for the eyes. Whether it’s exploring nature trails, riding bikes, or simply enjoying the outdoors, every second spent outside helps to safeguard your vision. Furthermore, the benefits of outdoor play go beyond visual health to include overall well-being and cognitive development. Encouraging children to participate in outdoor activities promotes creativity, resilience, and social connections, thus improving their overall quality of life. Developing bright solutions As parents, educators, and governments, we must develop a culture that values outdoor play to protect future generations’ visual health. We empower children to flourish in a digital world by fostering a love of nature at a young age and incorporating outside time into everyday activities. Outdoor play appears as a beacon of hope in the quest to maintain and preserve children’s vision, providing a simple yet effective way to battle the rising tide of myopia. Let us go on this transforming journey together, creating a world in which every child has the opportunity to appreciate the beauty around them.    The post Outdoor play could be a visionary solution for children’s eye health first appeared on The Optimist Daily: Making Solutions the News.
