Oof, that's a VERY critical piece of information. Never trust a headline!
And remember my friend, future events such as these will affect you in the future

Efficiency breakthrough cuts cost of fusion power

20th December 2021

Tokamak Energy has announced a more efficient design for the cryogenic electronics in fusion reactors. This provides a 50% reduction in the power needed for the cooling of high-temperature superconducting (HTS) magnets.

General Fusion Raised US$130 Million for Demo Nuclear Fusion Plant Around 2025
https://www.nextbigfuture.com/2021/12/d ... n2025.html
December 29, 2021 by Brian Wang

At the end of November, 2021, General Fusion announced they had raised $130 Million to build their demonstration nuclear fusion reactor.

The Series E funding round included the Business Development Bank of Canada, the hedge fund Segra Capital Management and several family-office investors.

General Fusion designs from the ground up to enable a practical, commercially-viable power plant. Electricity is generated from the fusion plant by pumping hot liquid metal through a heat exchanger to heat water, which then turns a steam turbine. General Fusion power plants will also be modular, allowing multiple units to energize large cities or heavy industry.

The key components of a Magnetized Target Fusion power plant are the plasma injectors, pistons and liquid metal vortex. Currently, General Fusion is developing and optimizing these components in parallel to accelerate construction of a demonstration power plant.

General Fusion was founded in 2002 with a goal to transform the world’s energy supply by developing the fastest, most practical, and cost-competitive path to commercial fusion power.

In 2006, Dr. Michel Laberge completed proof-of-principle experiments, and with the support of leading venture capital firms, General Fusion began building a team that today is recognized as a global leader in commercial fusion energy. The company has now grown to a team of more than 100 at its world class laboratories in Burnaby, just outside Vancouver, where it is developing the key components of the world’s first fusion power plant.

General Fusion hopes to have a large scale demo plant by 2025 and a commercial fusion system around 2030. The timelines slipped over the decades.

The UK Atomic Energy Authority (UKAEA) and General Fusion will build and operate its Fusion Demonstration Plant (FDP) at UKAEA’s Culham Campus. The FDP will demonstrate General Fusion’s proprietary Magnetized Target Fusion (MTF) technology. Construction starts 2022.

Chinese Fusion Reactor Maintains 70 Million Degrees Celsius For More Than 17 Minutes
https://www.heise.de/news/Chinesisches- ... 16278.html
https://www.heise.de ^

The Experimental Advanced Superconducting Tokamak (EAST) in Hefei in the east Chinese province of Anhui reports a new temperature record. At the end of last year, a plasma temperature of 70 million ° C could be maintained in the experimental nuclear fusion reactor for 1056 seconds, i.e. a good 17 minutes, reports the Institute for Plasma Physics at the Chinese Academy of Sciences (ASIPP). That is the longest time in which such a temperature could be kept constant.

This creates a solid basis for further research into energy generation from nuclear fusion, writes the ASIPP. Its general director Prof. Yuntao Song believes that the perfect ASIPP team will face any difficulty, no matter how difficult it is.

In May, the research team was able to maintain a plasma temperature of 120 million ° C for 101 seconds in the superconducting reactor of the tokamak type in an experiment, and the Chinese news agency Xinhua reported 160 million ° C for 20 seconds. An important step at the EAST is to be able to maintain a temperature of over 100 million ° C for a week. China participates in ITER

EAST is working on the international nuclear fusion project ITER in Cadarache in southern France. In addition to China, the EU, Japan, the USA, Russia, South Korea and India are involved in the project. The knowledge gained in China should help in southern France. In addition, the ASIPP is sending teams of experts to Cadarache, for example in the first quarter of 2021 when it came to installing the 330-ton PF6 field coil for the floor of the ITER, which was also manufactured in China.

Belgium to close all existing nuclear power plants

Boy these European Green parties are working hard to undermine the fight against climate change by shutting down perfectly good 0 emissions plants to replace with coal and fossil fuels...

Clearly an overhyped technology. A real shame.


The future isn't with fusion at this time it is with improved fission technologies like those based on SMRs and other advancements to fuels. Fusion is a way out and I don't expect this before mid to late century at earliest...

Hot stuff: Lab hits milestone on long road to fusion power
Source: AP

By SETH BORENSTEIN
With 192 lasers and temperatures more than three times hotter than the center of the sun, scientists hit — at least for a fraction of a second — a key milestone on the long road toward nearly pollution-free fusion energy.

Researchers at the National Ignition Facility at the Lawrence Livermore National Lab in California were able to spark a fusion reaction that briefly sustained itself — a major feat because fusion requires such high temperatures and pressures that it easily fizzles out.

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.

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.

Fusion Power Experiment in The UK Smashes Its Old Record in Major Step Forward
by Mike McCrae
February 9, 2022

https://www.sciencealert.com/european-f ... -of-energy

Introduction:
(Science Alert) Late last century, the Joint European Torus (JET) near Oxford, UK, churned out 22 megajoules of energy in what was, at the time, a record in fusion power.

Now, experimental upgrades have brought the facility into line with the technology anticipated for a major international project, resulting in the production of nearly three times that amount of power.

The advances are a major step forward for tokamak-based fusion, bringing us ever closer to a balance point where we can harvest a near endless stream of energy without the cost of polluting emissions or large amounts of radioactive waste.

"What we have learned in the past months will make it easier for us to plan experiments with fusion plasmas that generate much more energy than is needed to heat them," says Sibylle Günter, the Scientific Director of the Max Planck Institute for Plasma Physics.

Tokamaks might be the horse to back for reaching this milestone in energy production. Consisting of a relatively simple torus surrounded by a bank of seriously powerful magnets, they facilitate fusion by channeling bursts of hydrogen heated to dissolve into a plasma.
Don't mourn, organize.
