Lockheed Martin’s Compact Fusion Reactor Might Change Humanity Forever

Posted by in categories: nuclear energy, space travel

This is an invention that might possibly modify the civilization as we know it: A compact fusion reactor presented by Skunk Works, the stealth experimental technology section of Lockheed Martin. It’s about the size of a jet engine and it can power airplanes, most likely spaceships, and cities. Skunk Works state that it will be operational in 10 years.

Why Bezos and Microsoft are betting on this $10 trillion energy fix for the planet

Posted by in categories: business, nuclear energy, transportation

So far, no one has commercialized nuclear fusion, but the race is on to be the first to figure it out. Whoever does will be able to bring power to the more than 1 billion who don’t have access to electricity, power cars and help companies operate businesses without having to create harmful emissions.


Jeff Bezos and others have sunk more than $127 million into General Fusion, a start-up trying to commercialize fusion energy. Microsoft is partnering with the company. The goal: to provide energy to 1 billion people that don’t have electricity.

Researchers turn liquid metal into a plasma

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

Scientists at the University of Rochester’s Laboratory for Laser Energetics have achieved a plasma research first. They were able to convert the liquid metal deuterium to the plasma state and directly observe the interaction threshold.


For the first time, researchers at the University of Rochester’s Laboratory for Laser Energetics (LLE) have found a way to turn a liquid metal into a plasma and to observe the temperature where a liquid under high-density conditions crosses over to a plasma state. Their observations, published in Physical Review Letters, have implications for better understanding stars and planets and could aid in the realization of controlled nuclear fusion — a promising alternative energy source whose realization has eluded scientists for decades. The research is supported by the US Department of Energy and the National Nuclear Security Administration.

What is a Plasma?

Plasmas consist of a hot soup of free moving electrons and ions — atoms that have lost their electrons — that easily conducts electricity. Although plasmas are not common naturally on Earth, they comprise most of the matter in the observable universe, such as the surface of the sun. Scientists are able to generate artificial plasmas here on Earth, typically by heating a gas to thousands of degrees Fahrenheit, which strips the atoms of their electrons. On a smaller scale, this is the same process that allows plasma TVs and neon signs to “glow”: electricity excites the atoms of a neon gas, causing neon to enter a plasma state and emit photons of light.

CERN Creates Antimatter to Answer Fundamental Question of Universe

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

The concept of antimatter has delighted sci-fi fans for years, but it also poses a real question for physicists. Mathematically speaking, it makes sense that for every type of particle in our universe there exists a corresponding antiparticle which is the same but with the opposite charge — so to correspond with the electron, for example, there should be an antielectron, also known as a positron. When antimatter and matter come into contact, they both destroy each other in a flash of energy.

When the Big Bang happened, it should have created equal amounts of both matter and antimatter. And yet matter is everywhere and there is hardly any antimatter in our universe today. Why is that?

A new experiment from CERN, the European Organization for Nuclear Research, has been tackling the question by looking at how matter and antimatter could react differently to Earth’s gravitational field. Physicists think that antimatter could fall at a different rate than matter, which would help to explain why it is less prevalent. But in order to test this, they need to create antimatter particles such as positronium atoms. These are pairs of one electron and one positron, but they only live for a fraction of a second — 142 nanoseconds to be exact — so there isn’t enough time to perform experiments on them.

Check Out This Incredible X-Ray ‘Superbubble’ That’s Nearly 5,000 Light-Years Wide

Posted by in categories: cosmology, nuclear energy

This incredible image shows a pair of “nuclear superbubbles,” one over 4,900 light-years across and the other over 3,500 light-years. They’re emanating from the center of the galaxy NGC 3079, likely the result of a central black hole consuming matter and spewing it back out.

Or, the superbubbles could be from a starburst, a faster-than-usual stellar birth. The bubble-like shape could come from shock waves and compression within the cooler gas. But there’s still an element of mystery here, as the smaller bubble seems to be emanating synchrotron emission, or high-energy x-rays from spiraling electrons, while the larger bubble isn’t.

Tennessee Teen Builds Working Nuclear Fusion Reactor at Home

Posted by in category: nuclear energy

A Tennessee teen has become the youngest person in America—and possibly the world—to build a working nuclear reactor and achieve fusion.

Jackson Oswalt, now 14, set out on the ambitious project when he was just 12, according to USA Today, and achieved nuclear fusion in his Memphis home just hours before he turned 13 on Jan. 19, 2018.

“A couple of years back, all I did was play video games,” he told the news outlet. “And I decided I didn’t want to spend all my life doing video games.”

Experts: United States Should Build a Prototype Fusion Power Plant

Posted by in categories: biotech/medical, engineering, nuclear energy

The United States should devote substantially more resources to nuclear fusion research and build an ambitious prototype fusion power plant, according to a new report.

The report is the work of the National Academies of Sciences, Engineering, and Medicine. Its conclusion: it’s more important than ever for the U.S. and the world to explore roads to practical fusion power.
