New Physics at Play: Physicists Discover a New Force Acting on Water Droplets Moving Over Superhydrophobic Surfaces

Posted by in categories: physics, solar power, sustainability

Researchers at Aalto University have discovered a new force acting on water droplets moving over superhydrophobic surfaces like black silicon by adapting a novel force measurement technique to uncover the previously unidentified physics at play. This force, identified as air-shearing, challenges previous understandings and suggests modifications in the design of these surfaces to reduce drag, potentially improving their efficiency and application in various fields.

Microscopic chasms forming a sea of conical jagged peaks stipple the surface of a material called black silicon. While it’s commonly found in solar cell tech, black silicon also moonlights as a tool for studying the physics of how water droplets behave.

Black silicon is a superhydrophobic material, meaning it repels water. Due to water’s unique surface tension properties, droplets glide across textured materials like black silicon by riding on a thin air-film gap trapped beneath. This works great when the droplets move slowly—they slip and slide without a hitch.

More Than Just Fool’s Gold: Scientists Uncover Hidden Treasure in Pyrite

Posted by in categories: computing, sustainability, transportation

There’s a reason airlines won’t let you put your laptop in your checked luggage; the lithium-ion battery poses a serious fire hazard. But why? Lithium is incredibly reactive.

For instance, pure lithium violently interacts with seemingly innocuous water, releasing heat and forming highly flammable hydrogen. This reactivity, however, is exactly why lithium makes a great material for batteries, and why it is a critical mineral for the green energy transition.

Lithium-ion batteries are widely used in electric vehicles. Plus, they can store energy produced by renewable resources like solar and wind.

Tesla set to roll out awesome new Sentry Mode feature

Posted by in categories: security, sustainability, transportation

Tesla is set to roll out an awesome new feature with Sentry Mode, allowing owners to watch the video clip recorded by the car on their phone.

Sentry Mode is a security feature on Tesla vehicles that records instances and events that occur near the car. It has helped solve things as simple as petty vandalism, like keying, and even liability in accidents.

For years, it has been available on Tesla vehicles. Yet, people are still not aware of this capability and continue to commit crimes on the cars, not realizing they are being recorded.

Scientists make breakthrough with advanced technology generating water from thin air — and it could save millions of lives

Posted by in categories: energy, physics, sustainability

I found this on NewsBreak.

Researchers in China have reportedly developed a new technology similar to hydropanels for harvesting water out of thin air that is powered by energy from the sun. The device could be especially useful in dry, arid areas where water — but not sunlight — is hard to come by.

Watch: Tesla Optimus takes a walk bare-bones in a new video by Elon Musk

Posted by in categories: Elon Musk, sustainability, transportation

When we thought Tesla’s Optimus project was settling into a routine of shirt-folding chores and tasks, Elon Musk threw us a curveball. A new video, shared by the Tesla CEO on X(formerly Twitter), showcases Optimus in its new Gen 2 avatar in a state we haven’t seen before, walking but decidedly undressed.

But unlike the polished presentations we’ve seen before, this time, Optimus is bare-bones, revealing its intricate inner workings in all their unpolished glory.

Increasing Deep Water Oxygen Levels by “Mixing Down” Oxygen

Posted by in categories: climatology, computing, health, sustainability

With climate change warming the oceans, this results in drastic consequences for marine life in deep water environments, but can steps be taken to help mitigate these effects? This is what a recent study published in Nature Communications hopes to address as a team of researchers from the United Kingdom investigated how “mixing down” oxygen levels in the ocean could help contribute to a more suitable environment for deep sea life. This study holds the potential to help scientists, conservationists, legislators, and the public better understand the steps that can be taken to mitigate the long-term effects of climate change.

Decreasing oxygen levels in the ocean is a natural phenomenon, but climate change has been predicted to accelerate this process, which could lead to massive decreases in oxygen levels in deep water environments and pose catastrophic consequences for marine life. For the study, the researchers used new methods that combine ocean water data from the Celtic Sea and computer models to ascertain how deep water oxygen levels could be replenished during the warmer summer months. In the end, they determined that summertime storms can result in the “mixing down” of oxygen and decrease this oxygen loss by almost half, which also shows promise for putting floating wind farms in the northern North Sea and Celtic Sea to assist in this process.

“There is growing concern for the health of our coastal oceans as the climate warms because warmer water holds less oxygen,” said Dr. Tom Rippeth, who is a Professor of Physical Oceanography at Bangor University and lead author of the study. “Living creatures in the ocean are reliant on oxygen to survive in the same way as animals on land are. Oxygen is also used up as rotting matter decomposes in the depths of the ocean. This creates a summer oxygen deficit in the deep seas around the UK. Unfortunately, as our climate warms, this deficit is forecast to grow.”
