Flying taxi service coming to Chicago using eVTOL aircraft

Posted by in categories: sustainability, transportation

In the latest sign of growing interest in the flying taxi sector, United Airlines and air mobility startup Archer Aviation have announced an upcoming service for hops between downtown Chicago and O’Hare International Airport.

The service will offer a sustainable, low-noise, and cost-competitive alternative to ground transportation for folks traveling to and from the airport, United and Archer said in a release.

Deadly cyclone Freddy has become Earth’s longest-lived tropical storm

Posted by in categories: climatology, sustainability

Remarkably, the storm has rapidly intensified six times.

Rapid intensification describes an uptick in winds of 35 mph or greater in 24 hours. Research has shown rapid intensification increasing in frequency in many ocean basins because of rising ocean temperatures linked to human-caused climate change.

Ford to build next-gen EV truck at $5.6B factory in 2025

Posted by in categories: sustainability, transportation

Ford said Friday that its $5.6 billion BlueOval City complex outside of Memphis, Tennessee will include a truck plant capable of producing 500,000 electric vehicles a year.

The first vehicle to come off the line will be a next-gen electric truck, code named Project T3, in 2025.

Construction at BlueOval City, the epicenter for its future EV and battery cell manufacturing and a key component toward its goal to sell 2 million EVs annually by late 2026, began last fall.

AI-powered Google Maps’ immersive view now available for a select few

Posted by in categories: mapping, robotics/AI, sustainability

A few select users will now be able to enjoy Google Maps’ immersive view, according to a blog by the company published last month. The new feature is meant to allow users to reimagine how they explore and navigate, while helping them make more sustainable choices.

“Immersive view is an entirely new way to explore a place — letting you feel like you’re right there, even before you visit. Using advances in AI and computer vision, immersive view fuses billions of Street View and aerial images to create a rich, digital model of the world. And it layers helpful information on top like the weather, traffic, and how busy a place is,” said Chris Phillips, VP & General Manager, Geo, in the blog.

Researchers successfully tested a passenger hybrid-electric plane

Posted by in categories: engineering, sustainability, transportation

Engineering researchers at the University of Arkansas marked a significant advancement in their field by completing a successful test flight of an electric motor drive on a hybrid electric aircraft, according to a university release.

The project may have a substantial impact on the aeronautics sector and have enormously positive effects on environmental quality.

These French Fries Last 90 Days Outside the Fridge or Freezer

Posted by in categories: biological, food, life extension, sustainability

Food tech startup Farther Farms has developed a process that keeps foods that would normally need to be refrigerated or frozen fresh at room temperature — and their first product is a bag of shelf-stable French fries.

The cold chain: Microorganisms are a major cause of food spoilage, and they thrive at room temperature. By keeping some foods cold, we can slow the growth of these microbes, extending the life of the food.

To do that, the foods must be prepared, shipped, and stored along a temperature-controlled supply chain (a “cold chain”). If the cold chain is broken at any point along the way, the food may quickly become unsafe to eat.

Built Robotics Unveils Autonomous Pile Driving Robot, Expediting Solar Rollout

Posted by in categories: economics, robotics/AI, solar power, sustainability

Built Robotics has introduced an autonomous pile driving robot that will help build utility-scale solar farms in a faster, safer, more cost-effective way, and make solar viable in even the most remote locations. Called the RPD 35, or Robotic Pile Driver 35, the robot can survey the site, determine the distribution of piles, drive piles, and inspect them at a rate of up to 300 piles per day with a two-person crew. Traditional methods today typically can complete around 100 piles per day using manual labor.

The RPD 35 was unveiled today at CONEXPO-CON/AGG in Las Vegas, the largest construction trade show in North America and held every three years.

The 2022 Inflation Reduction Act “Building a Clean Energy Economy” section includes a goal to install 950 million solar panels by 2030. With solar farms requiring tens of thousands of 12-to 16-foot-long piles installed eight feet deep with less than an inch tolerance, piles are a critical component of meeting that target.

Elon Musk’s The Boring Company seeks to double the size of its Vegas Loop

Posted by in categories: Elon Musk, sustainability, transportation

Elon Musk’s Boring Company is doubling down on its Vegas bet, with a proposal that would expand its underground transport system to 65 miles of tunnels below the streets of Sin City.

The proposed network map, which was recently filed with the city of Las Vegas and not previously reported, depicts dozens of tunnels criss-crossing the city to reach more casinos, retail zones, the University of Nevada Las Vegas campus and, for the first time, even residential areas. The proposed transit system is comprised of 69 stations and 65 miles of tunnels, according to planning documents, plus an unknown number of Tesla vehicles.

If successful, a Loop station would be located within a few blocks of almost anywhere in central Las Vegas. Five stations would serve the University of Nevada; and Allegiant Stadium — home to the Raiders NFL team — would get extra links to the west of the city. Harry Reid International Airport would have several stations surrounding it, although none actually serving the passenger terminal.

Fourier Transformations Reveal How AI Learns Complex Physics

Posted by in categories: climatology, mathematics, physics, robotics/AI, sustainability

One of the oldest tools in computational physics — a 200-year-old mathematical technique known as Fourier analysis — can reveal crucial information about how a form of artificial intelligence called a deep neural network learns to perform tasks involving complex physics like climate and turbulence modeling, according to a new study.

The discovery by mechanical engineering researchers at Rice University is described in an open-access study published in the journal PNAS Nexus, a sister publication of the Proceedings of the National Academy of Sciences.

“This is the first rigorous framework to explain and guide the use of deep neural networks for complex dynamical systems such as climate,” said study corresponding author Pedram Hassanzadeh. “It could substantially accelerate the use of scientific deep learning in climate science, and lead to much more reliable climate change projections.”

Electroactive bacterium generates well-defined nanosized metal catalysts with remarkable water-splitting performance

Posted by in categories: biological, chemistry, nanotechnology, particle physics, sustainability

A biological method that produces metal nanoclusters using the electroactive bacterium Geobacter sulfurreducens could provide a cheap and sustainable solution to high-performance catalyst synthesis for various applications such as water splitting.

Metal nanoclusters contain fewer than one hundred atoms and are much smaller than nanoparticles. They have unique electronic properties but also feature numerous active sites available for catalysis on their surface. There are several synthetic methods for making nanoclusters, but most require multiple steps involving and harsh temperature and pressure conditions.
