Northrop Grumman wins DARPA contract for a railway on the Moon

Posted by in categories: nuclear energy, space

In preparation for a permanent human colony on the Moon, DARPA has awarded a contract to Northrop Grumman to develop a lunar railway concept, as part of the 10-year Lunar Architecture (LunA-10) Capability Study.

Running a train on the Moon may seem profoundly silly, but there is some very firm logic behind it. Even as the first astronauts were landing on the Sea of Tranquility in 1969, it was realized that a permanent human presence on Mars would require an infrastructure to maintain it. That includes mines for water ice, nuclear power plants, factories, and railways.

Though many people think the Moon is small, it is, in fact, a very large place with a surface area equivalent to that of Africa. Over such an expanse, even a limited presence would require some sort of a transport system to link various outposts and activities.

Preventing magnet meltdowns before they can start

Posted by in categories: biotech/medical, nuclear energy

The particle accelerators that enable high-energy physics and serve many fields of science, such as materials, medical, and fusion research, are driven by superconducting magnets that are, to put it simply, quite finicky.

Synchrotron nuclear facility saves big with massive solar push

Posted by in categories: nuclear energy, particle physics, solar power, sustainability

The Australian Synchrotron, a crown jewel of Australian scientific infrastructure, is making major strides towards sustainable energy independence. The nuclear research facility recently completed the installation of 3,200 solar panels which now blankets the facility’s rooftops. This move is expected to generate substantial savings and support Synchrotron’s world-class research.

The state-of-the-art particle accelerator has now gone green with a 1.59 MW/ 1,668 kWh rooftop solar system. The facility will save about $2 million in energy costs over the next five years.

Startup Says Its Coin-Sized Nuclear Battery Could Fly Drones “Continuously”

Posted by in categories: drones, nuclear energy

Imagine never having to change a battery in a device ever again — or, in fact, a battery that could outlive you.

That’s what Betavolt, a Chinese tech company, is claiming with its newly unveiled miniature nuclear battery that it says can keep working for up to 50 years.

The Beijing-based company claims to have entered the “pilot stage” for the battery, which is smaller than a coin and will soon put it into mass production.

What is the big rip, and can we stop it?

Posted by in categories: cosmology, nuclear energy, particle physics

If two points were ripped apart faster than light, they would no longer interact through any force of physics. Whereas a constant dark energy would leave behind already-intact objects, like clusters of galaxies, phantom energy could tear them apart. In a finite amount of time, billions of years from now, clusters would tear apart, followed by ever-smaller objects. Even atomic and nuclear bonds would not withstand the onslaught.

Eventually, space itself would dissolve in an event known as the Big Rip. Any two points, no matter how close, would be ripped infinitely far away from each other. The very structure of space-time, the causal foundations that make our universe work, would no longer behave. The universe would just break down.

However, luckily, most physicists do not believe this scenario can actually happen. For one, it’s unclear how this process of ripping interacts with the other laws of physics. For example, quarks cannot be torn apart — when you attempt to do so, you need so much energy that new quarks materialize out of the vacuum. So ripping apart quarks just might lead to other, interesting interactions.

Plasma oscillations propel breakthroughs in fusion energy

Posted by in categories: nuclear energy, particle physics

Most people know about solids, liquids, and gases as the main three states of matter, but a fourth state of matter exists as well. Plasma—also known as ionized gas—is the most abundant, observable form of matter in our universe, found in the sun and other celestial bodies.

Creating the hot mix of freely moving electrons and ions that compose a often requires extreme pressures or temperatures. In these , researchers continue to uncover the unexpected ways that plasma can move and evolve. By better understanding the motion of plasma, scientists gain valuable insights into solar physics, astrophysics, and fusion.

In a paper published in Physical Review Letters, researchers from the University of Rochester, along with colleagues at the University of California, San Diego, discovered a new class of plasma oscillations—the back-and-forth, wave-like movement of electrons and ions. The findings have implications for improving the performance of miniature particle accelerators and the reactors used to create fusion energy.
