New catalysts steer hydrogen fuel cells into mainstream

Posted by in categories: biological, chemistry, space travel, sustainability

Cornell chemists have discovered a class of nonprecious metal derivatives that can catalyze fuel cell reactions about as well as platinum, at a fraction of the cost.

This finding brings closer a future where fuel cells efficiently power cars, generators and even spacecraft with minimal greenhouse gas emissions.

“These less expensive metals will enable wider deployment of hydrogen fuel cells,” said Héctor D. Abruña, the Émile M. Chamot Professor in the Department of Chemistry and Chemical Biology in the College of Arts and Sciences. “They will push us away from and toward .”

A Window Into the Future of Wave Energy

Award Helps Move Cost-Effective, Productive, Robust Wave Energy Design a Step Closer to Commercialization and Widespread Use

In 1974, Stephen Salter, a professor at the University of Edinburgh, sent his “ducks” into the Scottish seas, launching the world’s first major wave energy project. But the ocean’s rough heaves and surges proved too much for his house-sized, floating generators. Like the more recent Pelamis’ P-750 model and Aquamarine’s Oysters, they succumbed to the power they were meant to harness.

Low-cost self-healing material for robotic hands and arms

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

Soft sensing technologies have the potential to revolutionize wearable devices, haptic interfaces, and robotic systems. However, most soft sensing technologies aren’t durable and consume high amounts of energy.

Now, researchers at the University of Cambridge have developed self-healing, biodegradable, 3D-printed materials that could be used in the development of realistic artificial hands and other soft robotics applications. The low-cost jelly-like materials can sense strain, temperature, and humidity. And unlike earlier self-healing robots, they can also partially repair themselves at room temperature.

“Incorporating soft sensors into robotics allows us to get a lot more information from them, like how strain on our muscles allows our brains to get information about the state of our bodies,” said David Hardman from Cambridge’s Department of Engineering the paper’s first author.

In a way, it could mean climate change is linked to an “immature technosphere”.

It’s called an epiphenomenon.

Elon Musk’s Boring Company has submitted a proposal for a 6.2-mile underground transit system in Miami

Posted by in categories: Elon Musk, sustainability, transportation

Elon Musk’s The Boring Company has submitted a proposal to construct a 6.2-mile underground transit system in Miami, Insider can reveal.

The North Miami Beach Loop would ferry Tesla vehicles between seven stations along State Road 826, between the Golden Glades Transit Center and Sunny Isles Beach at Newport Pier, according to the proposal, seen by Insider.

The Boring Company estimated that the loop would initially be able to carry more than 7,500 passengers per hour, and could be scaled to carry more than 15,000 per hour.

Tesla announces it has produced 1 million next-gen 4680 battery cells

Posted by in categories: sustainability, transportation

Tesla has announced that it has produced 1 million of its next-generation 4,680 battery cell at its pilot factory in California.

The announcement comes as Tesla is expected to start deliveries of its new Model Y equipped with its 4,680 cell and structural battery pack.

In 2020, Tesla unveiled its new 4,680 battery cell, a new tabless cylindrical cell in a much bigger format that the company claimed produces six times the power and five times the energy capacity while significantly reducing the cost.

Self-healing materials for robotics made from ‘jelly’ and salt

Posted by in categories: robotics/AI, sustainability

Researchers have developed self-healing, biodegradable, 3D-printed materials that could be used in the development of realistic artificial hands and other soft robotics applications.

The low-cost jelly-like materials, developed by researchers at the University of Cambridge, can sense strain, temperature and humidity. And unlike earlier robots, they can also partially repair themselves at room temperature.

The results are reported in the journal NPG Asia Materials.

Engineering Student Builds Solar Panels That Don’t Need Direct Sunlight, Uses UV Light

Posted by in categories: engineering, solar power, sustainability

However, now an engineer from the Philippines has developed a new kind of solar panel that doesn’t really need sunlight to generate electricity. At least not directly.

Developed by Carvey Ehren Maigue, a student at Mapua University in the Philippines, the novel solar panels (called AuRES) are designed to feed off the UV rays of the sun — something that even dense cloudy days cannot block.

A next-generation Chevrolet could have airless tires

Posted by in categories: business, sustainability, transportation

Michelin has been working with General Motors to develop airless tires that will be sold on a next-generation Chevrolet Bolt electric car, expected to go on sale in the next few years, a Michelin executive said. It could mark the decline of over 130 years of tire tradition but also the end of one of the most annoying aspects of car ownership: keeping air in the tires.

“We want to bring the next generation of the Chevrolet Bolt with airless tires,” Alexis Garcin, president of Michelin North America said in an interview with CNN Business, “and it’s going to happen now in the next three to five years.”
