Iron-from-ore laser smelter by Luminar Metal: A new method for producing steel without coal
Steelmaking is responsible for 7-9% of global CO2 emissions. The most common way to produce steel involves using coal to turn iron ore into pure iron. Luminar Metal’s new method eliminates the need for coal by using lasers to turn ore into pure iron. The process, known as direct reduction, generates almost pure iron and a nearly pure form of oxygen as byproducts, which can be sold to cover the cost of running the lasers. The company’s first plant in Indiana will use energy from the grid to power the lasers, but future plants could be solar-powered.
The breakthrough here is the lasers themselves. Luminar Metal’s engineers have figured out how to use relatively inexpensive fiber lasers to heat iron oxide pellets to near-molten temperatures quickly. The faster the pellet melts, the less energy is lost to the surrounding chamber. The result is a process that requires 7% less energy than the traditional method. The company expects its Indiana plant to be operational in 2026.

The Impact of Social Media on Mental Health
In today’s digital age, social media has become an integral part of our daily lives. From sharing photos and updates with friends and family to staying informed about current events, social media platforms like Facebook, Instagram, and Twitter have revolutionized the way we connect with others. However, with this increased connectivity comes a new set of challenges, particularly when it comes to our mental health.
One of the most significant impacts of social media on mental health is the potential for negative comparison. When scrolling through our feeds, it’s easy to fall into the trap of comparing ourselves to others. Whether it’s someone’s perfectly curated Instagram feed or their seemingly perfect life updates on Facebook, social media can create feelings of inadequacy and low self-esteem. This constant comparison can lead to increased feelings of anxiety, depression, and overall dissatisfaction with our own lives.
Another major concern with social media is the rise of cyberbullying. With the anonymity that social media provides, individuals may feel emboldened to say hurtful and harmful things to others online. This can have devastating effects on the mental health of the victim, leading to feelings of shame, isolation, and even suicidal ideation. The constant fear of being targeted online can create a sense of paranoia and anxiety that can be difficult to shake.
Additionally, social media can also contribute to feelings of FOMO, or the fear of missing out. Seeing our friends and acquaintances post about their exciting adventures and social gatherings can make us feel like we’re missing out on important experiences. This fear of missing out can lead to increased feelings of loneliness and isolation, as well as pressure to constantly be doing something exciting or noteworthy to share online.
On the flip side, social media can also have positive impacts on mental health. For many, social media provides a sense of community and support that may not be readily available in their day-to-day lives. Online support groups, mental health advocacy pages, and positive affirmations shared by friends can all contribute to a sense of belonging and connection.
Ultimately, the impact of social media on mental health is complex and multifaceted. While it can provide a sense of connection and support, it can also contribute to feelings of inadequacy, loneliness, and anxiety. It’s important for individuals to be mindful of their social media use and take steps to protect their mental health, such as setting boundaries around screen time, curating their feeds to promote positive content, and seeking support from mental health professionals when needed. By being aware of the potential pitfalls of social media and taking proactive steps to mitigate them, we can ensure that our online interactions contribute positively to our overall well-being.
