Report finds no single alternative to fossil-based jet fuel to support present demand

Decarbonizing Aviation: A Whole Systems Approach

The need to decarbonize the aviation industry by weaning it off of fossil fuels presents an enormous challenge, but there is a plan of attack that holds great promise if executed properly, according to a lead scientist at Heriot-Watt University. This approach is called a "whole systems approach," and it is a holistic means of meeting the goals of decarbonizing the aviation industry.

At the core of the whole systems approach lies the idea of proactive, holistically-minded decision making. Whereas in the past the aviation industry may have taken a piecemeal approach to reducing emissions, the new whole systems approach seeks to create systemic, proactive steps to reduce emissions through multiple avenues. This might include instituting carbon offsets, investing in sustainable fuel sources, and utilizing technologies that are designed to reduce fuel consumption.

The whole systems approach to aviation is an ambitious program, but it has the potential to revolutionize the industry like nothing before it. If implemented correctly, it could result in drastic emissions reductions in the coming years, allowing the aviation industry to become a leader in the fight against climate change.

Underwater acoustic wireless communication using TCP/IP

Acoustic communication through water is a phenomenon well known among numerous sea creatures, such as whales, dolphins, and other cetaceans. Crustaceans and fish also partake in this type of communication with sound. However, the origin of this aquatic communication dates back to the time of Leonardo da Vinci, who first described an acoustic listening technique in 1490, although modern-day active sonar methods are vastly more sophisticated than his passive technique.

The conversation between sea creatures often functions as a powerful form of communication, as well as a way to locate prey and navigate. Different creatures produce and receive different types of sounds based upon the nature of their environment. As technology advances, further research on underwater acoustics can be explored, as well as its potential applications in the field of communications and navigation.

Almost all cobalt can be recycled using new method requiring less energy with little environmental impact

Researchers Create More Eco-Friendly Trick to Retrieve Cobalt from Used Lithium-ion Batteries

Researchers at Linnaeus University have developed a more environmentally friendly way of retrieving cobalt from used lithium-ion batteries. With a liquid solvent made of readily available substances, derived from urine and acetic acid, over 97 percent of the cobalt can be recovered. The researchers see good potential for large-scale application.

The new solvent is composed of ammonia and a source of acetate, both of which are derived from urine and acetic acid. This isn't the first time urine has been used for environmentally friendly methods; its high ammonium content makes it an ideal source for extracting cobalt.

The cobalt extraction process is expensive and highly energy intensive, so this method of extraction is both cost-effective and energy-saving. It also uses chemicals that are much safer for the environment compared to traditional methods.

The team aims to improve the solvent's performance even further to allow for the extraction of other valuable metals such as nickel, manganese and molybdenum. They also plan to investigate potential applications in other industries, such as the production of fuel cells and batteries.

This research demonstrates the viability of using sustainable, natural methods to recover metals from used lithium-ion batteries. The researchers' method is a significant step forward in creating a more sustainable future.

Flights and firefighting: Companies push into the metaverse

My Ride in an Air Taxi in Busan, South Korea

I climbed into the front seat of the air taxi, buckled the seat belt and braced as the aircraft lifted off. The futuristic cityscape of Busan, South Korea, dropped away, and a digital avatar popped up on the windscreen with a message. With the city disappearing beneath me, I knew this was going to be a truly memorable experience.

The Air Taxi of Busan

The air taxi platform in Busan is powered by advanced technology, with regulators and operators committed to creating a safe, efficient, and affordable form of transportation. The flights are fast and efficient: connecting parts of South Korea that other forms of transport can’t reach. Enjoy the amazing views of the city from the air.

The Pilot and Digital Avatar

The pilot of the air taxi was to the point and gave me clear instructions. He gave me an overview of the destination and estimated time of arrival. The digital avatar in the windscreen turned out to be an important service provided by the operators; the avatar made sure we were on the correct route, with constant updates on our location. It was very reassuring.

My Memorable Experience

The entire experience of the air taxi was more than I expected it to be. It was a unique and memorable experience that I will never forget. With the incredible views of Busan, South Korea, and the reassuring digital avatar, this was definitely a flight I will never forget.

Here are the countries that have bans on TikTok

U.S. and Canada Ban TikTok on Government-Issued Mobile Devices

The U.S. and Canada have issued orders this week banning the use of the popular video-sharing app, TikTok, on government-issued mobile devices. This comes as a response to the growing worries about privacy and cybersecurity concerns related to the app.

TikTok has grown quickly in popularity in recent years, and has been downloaded onto over one billion devices worldwide. However, privacy concerns have been raised about the app as it is owned by Chinese tech giant ByteDance, and the fact it collects huge amounts of user data for advertising purposes.

The ban is an attempt to protect government data from potential vulnerabilities. As TikTok is seen to be more vulnerable to hacking due to its connections with China, the ban is meant to prevent any governmental information from becoming compromised.

The order comes as the U.S. and Canada are becoming increasingly worried about the potential misuse of data from Chinese-owned apps. This is just the latest in a string of bans of Chinese-owned apps and products issued by the two countries.

TikTok has since responded to the ban, stating that they take security and privacy very seriously and are constantly improving their measures to ensure user safety.
