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.

“We have to ask ourselves,” said Krish Thiagarajan Sharman, the endowed chair in renewable energy at the University of Massachusetts Amherst, “why have we been working on this for so long? Why don’t we have grid-ready, commercial-scale wave energy systems out in the world?”

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.

The idea is that the ordinary function of one thing can generate a secondary effect that seems unrelated and beyond its scope of influence. And when it comes to the interconnected systems of the Earth, we see it all the time.

Plants, for example, found their way via evolution to photosynthesis, which greatly improved their survival. But it also led to them releasing oxygen into the atmosphere, and that changed everything: One form of life seeded a planet-wide transformation, just by pursuing its own nature.

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 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.

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.

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.”

New solar panels that don’t need sunlight have been invented and could revolutionize the green energy initiative.

The idea of solar panels that don’t need sunlight might sound crazy, but it’s not completely impossible. As a cornerstone of the revolution to bring more clean energy to people, solar panels have become one of the best options out there. However, these energy conductors have one fatal flaw. They require direct sunlight to create energy. What if we could remove that flaw, though? That was the idea behind AuREUS, a new solar panel that doesn’t rely on direct sunlight to generate energy.

Solar panels are a cornerstone of the clean energy revolution. And yet, they have one great flaw: when the clouds roll in their productivity dives.

Now, a new type of solar panel has been developed by an electrical engineering student at Mapua University that harvests the unseen ultraviolet light from the sun that makes it through even dense cloud coverage. Maigue, who won the James Dyson Sustainability Award for his creation, hopes it will soon be used on the windows and walls of large buildings, turning them into constant sources of energy.

The solar panels, developed by student Carvey Maigue, won this year’s Dyson Sustainability Award. Click here to find out more.
