Burning plasma! Controlled nuclear fusion on Earth briefly sustains itself

Posted by in categories: nuclear energy, particle physics

We’ve been trying for a long time to make a tiny Sun on Earth, one that would sustainably produce energy by nuclear fusion of hydrogen or similar atoms. Come to think of it, I’d like one for my basement.

Fusion requires quite a bit of heat to get going, but once it does, it starts producing its own heat. If you can keep that system contained so it doesn’t expand too much or allow too much heat to escape, further fusion happens. If it reaches a point where self-heating becomes the primary driver of fusion, you have yourself a “burning plasma”.

A Novel ‘Artificial Leaf’ Captures 100 Times More Carbon Than Others

Posted by in categories: engineering, nuclear energy

Using less power than a lightbulb. A team of engineers at the University of Illinois Chicago (UIC) has developed a relatively low-cost “artificial leaf” that can capture carbon dioxide at rates 100 times faster than existing systems, bringing us one step closer to the goal of engineering the process of photosynthesis by which plants convert sunlight, water, and carbon dioxide into energy.

Here’s What Happens to Nuclear Waste

Posted by in categories: government, nuclear energy

Nuclear power could be essential to weaning the world off fossil fuels.

Nuclear power is a powerful form of energy that allows us to produce clean electricity. However, the waste it produces is difficult to tackle and is often the reason nuclear power has not become as popular as perhaps it should be. It is estimated that there are currently around 370,000 tonnes of spent nuclear fuel in temporary storage around the world, according to the International Atomic Energy Agency.

Burn, baby, burn: Nuclear scientists achieve major fusion feat

Posted by in categories: nuclear energy, particle physics

The ultimate goal, still years away, is to generate power the way the sun generates heat, by smooshing hydrogen atoms so close to each other that they combine into helium, which releases torrents of energy.

WATCH: Is alluring but elusive fusion energy possible in our lifetime?

A team of more than 100 scientists published the results of four experiments that achieved what is known as a burning plasma in Wednesday’s journal Nature. With those results, along with preliminary results announced last August from follow-up experiments, scientists say they are on the threshold of an even bigger advance: ignition. That’s when the fuel can continue to “burn” on its own and produce more energy than what’s needed to spark the initial reaction.

NASA’s First Test to Lower the Sound of Sonic Booms Was Successful

Posted by in categories: nuclear energy, physics, transportation

The Concorde’s successor might be quieter.

NASA has completed the first test of the works on lowering the volume of supersonic flights in an effort to lift the ban on commercial supersonic flights, NASA’s Glenn Research Center announced.

The sonic booms happen when the merge of shock waves, created by breaking the sound barrier at the speed of 767 mph (1,235 kph). The huge amount of sound energy, approximately 110 decibels, generated by sonic booms sounds like thunderclaps or explosions and can be heard from 30 miles (48 km) away, which is why supersonic commercial flights are banned by the Federal Aviation Administration (FAA). physicists confirm that they have achieved a stage in nuclear fusion called “burning plasma”.

Structured thermal armor achieves liquid cooling above 1,000°C and solves challenge presented by Leidenfrost effect

Posted by in categories: engineering, nuclear energy

A research team led by scientists from City University of Hong Kong (CityU) has recently designed a structured thermal armor (STA) that achieves efficient liquid cooling even over 1,000°C, fundamentally solving a 266-year-old challenge presented by the Leidenfrost effect. This breakthrough can be applied in aero and space engines, as well as improve the safety and reliability of next-generation nuclear reactors.

The research has been led by Professor Wang Zuankai from CityU’s Department of Mechanical Engineering (MNE), Professor David Quéré from the PSL Research University, France, and Professor Yu Jihong, Director of the International Center of Future Science, Jilin University and Senior Fellow of the Hong Kong Institute for Advanced Study at CityU.

The findings were published in the latest issue of the highly prestigious scientific journal Nature.

The United States military has a long record of being at the forefront of humankind’s technological achievements. For example, it was the U.S. Navy in the 1940s, led by Admiral Rickover, who pioneered the use of nuclear power as a propulsion device, and that eventually led to nuclear power plants for civilian use. Today, the military again leads the charge into the future with their innovations in robotics and their many applications across the entire infrastructure of the organization. We will talk about MAARS, Robobee, DOGO, SAFFiR and Gladiator!

China set a ground-breaking record with its “artificial sun,” which superheated plasma to temperatures five times hotter than the sun. The Experimental Advanced Superconducting Tokamak (EAST) nuclear fusion reactor reached 158 million degrees Fahrenheit for 1,056 seconds (17 minutes, 36 seconds). This latest breakthrough brings the country one step closer toward its goal for unlimited clean fusion energy.

China’s EAST surpassed France’s Tore Supra tokamak record, set in 2003 when it superheated plasma in its coiling loop to identical temperatures for 390 seconds. Also, in May 2021, EAST set another record by running at 216 million F for 101 seconds. The fusion reactor achieved a peak temperature of 288 million Fahrenheit for 20 seconds during this experiment. In comparison, the sun’s core reaches approximately 27 million Fahrenheit.
