The threat of wildfires is rising. So is new artificial intelligence solutions to fight them

Posted by in categories: climatology, robotics/AI, satellites, sustainability

Wildfires fueled by climate change have ravaged communities from Maui to the Mediterranean this summer, killing many people, exhausting firefighters and fueling demand for new solutions. Enter artificial intelligence.

Firefighters and startups are using AI-enabled cameras to scan the horizon for signs of smoke. A German company is building a constellation of satellites to detect fires from space. And Microsoft is using AI models to predict where the next blaze could be sparked.

With wildfires becoming larger and more intense as the world warms, firefighters, utilities and governments are scrambling to get ahead of the flames by tapping into the latest AI technology—which has stirred both fear and excitement for its potential to transform life. While increasingly stretched first responders hope AI offers them a leg up, humans are still needed to check that the tech is accurate.

Stanford engineers invent a solar panel that generates electricity at night

Posted by in categories: particle physics, solar power, space, sustainability

“If you can get up to a watt per square meter, it would be very attractive from a cost perspective,” Assawaworrarit says.

The invention taps into a source of energy that’s easily overlooked

The Earth is constantly receiving a tremendous amount of energy from the Sun, to the tune of 173,000 terrawatts. Clouds, particles in the atmosphere, and reflective surfaces like snow-covered mountains immediately reflect 30 percent of that energy out into space. The rest of it ends up warming the land, oceans, clouds, atmosphere, and everything else on the planet.

Inside One of Europe’s Largest Urban Development Projects—aspern Seestadt

Posted by in categories: energy, mapping, sustainability

The result: aspern Seestadt, reclaims a brownfield area to create a development that embraces new urban ideals while retaining the classical urban structure of old Vienna.

As aspern Seestadt has evolved, it has emerged as one of Europe’s most dynamic planned communities and an incubator for smart city initiatives. Geographic information system (GIS) technology helps planners implement clean energy and low-emission strategies and aids the long-range planning and implementation to ensure that aspern Seestadt achieves a unique balance of sustainability and livability.

-Vienna’s sustainable city within a city can be a model used by developing and developed countries dealing with housing crisis.

Canadian telecom uses AI cameras to fight wildfires

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

The technology is part of a project by Rogers to detect wildfires early.

A Canadian telecom is installing artificial intelligence (AI) cameras to monitor and prevent wildfires caused by climate change. This is according to a report by City News Everywhere.

“Climate change is a global issue,” said Tony Staffieri, CEO of Rogers, the company behind the new initiative.

Solar cars can reduce global charging needs by half

Posted by in categories: solar power, sustainability, transportation

A new study modeled the behavior of solar vehicles in 100 locations around the world.

According to a new study, solar energy can provide a range of between 6 and 18 miles (11 and 29 kilometers) for electric vehicles each day, cutting down on the requirement for charging by half. The study took into account the capabilities of solar-powered vehicles in urban settings in 100 locations across the world, modeling the behavior of the cars in busy cities.

The loss of dark skies is so painful, astronomers coined a new term for it

Posted by in categories: climatology, space, sustainability

Humanity is slowly losing access to the night sky, and astronomers have invented a new term to describe the pain associated with this loss: “noctalgia,” meaning “sky grief.”

Along with our propensity for polluting air and water and the massive amounts of carbon we’re dumping into the atmosphere to trigger climate change, we have created another kind of pollution: light pollution.

Tesla Giga Texas is looking to employ 60k workers when Cybertruck ramps: report

Posted by in categories: business, Elon Musk, sustainability, transportation

Jason Shawhan, Tesla’s director of manufacturing at Giga Texas, recently gave a rare talk about the facility’s existing operations and the company’s plans for the future. The executive shared the information during a keynote address at the State of Manufacturing conference and expo, which was held by the Austin Regional Manufacturers Association.

Tesla is the world’s most valuable automaker by market cap, and its CEO, Elon Musk, is one of the most visible chief executives in the auto industry. Despite this, Tesla has a reputation for being tight-lipped when it comes to the details of its operations. Rare appearances from high-ranking executives such as Shawhan, who serves as director of manufacturing at Gigafactory Texas, are therefore very interesting.

Shawhan did not disappoint, as he did share a number of important insights about the facility. As noted in a report from the Austin Business Journal, the executive confirmed that Giga Texas has become the second-largest private employer in the region because the factory currently employs over 20,000 workers today. This is a notable increase from the 12,277 employees that Tesla confirmed at the end of 2022. Considering Gigafactory Texas’ growth so far, it would appear that the facility would be outpacing Musk’s estimates.

New method to recycle materials inside lithium-ion batteries

Posted by in categories: energy, sustainability

Lithium-ion batteries (LIBs), which store energy leveraging the reversible reduction of lithium ions, power most devices and electronics on the market today. Due to their wide range of operating temperatures, long lifespan, small size, fast charging times and compatibility with existing manufacturing processes, these rechargeable batteries can greatly contribute to the electronics industry, while also supporting ongoing efforts towards carbon neutrality.

The affordable and eco-friendly recycling of used LIBs is a long sought-after goal in the energy sector, as it would improve the sustainability of these batteries. Existing methods, however, are often ineffective, expensive or harmful to the environment.

Moreover, LIBs heavily rely on materials that are becoming less abundant on Earth, such as cobalt and . Approaches that enable the reliable and cost-effective extraction of these materials from spent batteries would drastically reduce the need to source these materials elsewhere, thus helping to meet the growing LIB demand.

Cheap and efficient catalyst could boost renewable energy storage

Posted by in categories: particle physics, sustainability

Renewable energy generation, from sources like wind and solar, is rapidly growing. However, some of the energy generated needs to be stored for when weather conditions are unfavourable for wind and sun. One promising way to do this is to save the energy in the form of hydrogen, which can be stored and transported for later use.

To do this, the renewable energy is used to split water molecules into hydrogen and oxygen, with the energy stored in the hydrogen atoms. This uses platinum catalysts to spur a reaction that splits the water molecule, which is called electrolysis. However, although platinum is an excellent catalyst for this reaction, it is expensive and rare, so minimising its use is important to reduce system cost and limit platinum extraction.

Now, in a study published this week in Nature, the team have designed and tested a catalyst that uses as little platinum as possible to produce an efficient but cost-effective platform for water splitting.
