Thanks to renewables, ‘insanely cheap electricity’ is coming. But when?

Posted by in categories: futurism, nuclear energy

There’s even talk in some quarters that solar could one day fulfil the unrealised promise of nuclear power to generate electricity so abundant that it would be “too cheap to meter”.

So how cheap can solar get? And will you — the energy consumer — still have a power bill?

This future of cheap power is already here — at least sometimes.

Finally, a Fusion Reaction Has Generated More Energy Than Absorbed by The Fuel

Posted by in category: nuclear energy

A major milestone has been breached in the quest for fusion energy.

For the first time, a fusion reaction has achieved a record 1.3 megajoule energy output – and for the first time, exceeding energy absorbed by the fuel used to trigger it.

Although there’s still some way to go, the result represents a significant improvement on previous yields: eight times greater than experiments conducted just a few months prior, and 25 times greater than experiments conducted in 2018. It’s a huge achievement.

Fusion Energy Could Be a Reality in Less Than 5 Years

Posted by in categories: nuclear energy, physics

SPARC is aiming to be the first experimental device to achieve an energy-positive fusion reaction. New research suggests that this goal may soon be within reach.

With construction slated to begin in spring 2021, the team predicts it could be built within 3 to 4 years from that. Their goal is to achieve a Q factor of at least 2, basically meaning SPARC will pump out twice the energy needed to power it.

NASA is Building a Nuclear Reactor to Power Lunar and Martian Exploration!

Posted by in categories: health, nuclear energy, solar power, space travel, sustainability

NASA and the U.S. Dept. of Energy have come together to solicit design proposals for a nuclear reactor that will power Lunar and Martian exploration!


Over the next fifteen years, multiple space agencies and their commercial partners intend to mount crewed missions to the Moon and Mars. In addition to placing “footprints and flags” on these celestial bodies, there are plans to establish the infrastructure to allow for a long-term human presence. To meet these mission requirements and ensure astronaut safety, several technologies are currently being researched and developed.

At their core, these technologies are all about achieving self-sufficiency in terms of resources, materials, and energy. To ensure that these missions have all the energy they need to conduct operations, NASA is developing a Fission Surface Power (FSP) system that will provide a safe, efficient, and reliable electricity supply. In conjunction with solar cells, batteries, and fuel cells, this technology will allow for long-term missions to the Moon and Mars in the near future.

Experts Say Fusion Power Is Finally Starting to Look Imminent

Posted by in category: nuclear energy

If it sounds too good to be true, it probably is, right? Normally we’d say yes, but experts around the globe say nuclear fusion power, which holds the promise of clean and virtually limitless electricity, could be just around the corner. After nearly six decades with many promises but few results, new advancements may finally tip the scale, according to the Financial Times.

“Fusion is coming, faster than you expect,” Fusion Industry Association exec Andrew Holland told the publication.

There could be many benefits to nuclear fusion. Unlike nuclear fission it would create little waste and, as far as we know, could never result in an accident like Chernobyl. Insert a side-eye here for plans to dump radioactive water into Cape Cod Bay and the Pacific.

China’s New Space Nuclear Reactor Might Be 100 Times More Powerful Than NASA’s

Posted by in categories: nuclear energy, space travel

And the prototype design is already completed.

China’s space program has completed a prototype design for a powerful nuclear reactor, a report from the South China Morning Post reveals.

The country’s space program is building the device to keep up with other space agencies that have also drawn plans to go nuclear, such as NASA, which recently made a call for private firms to develop a nuclear fission system to power missions on the Moon within 10 years.

Korea’s Cutting-Edge Fusion Reactor Just Broke Its Own Record For Containing Plasma

Posted by in category: nuclear energy

Barely a year after the Korea Superconducting Tokamak Advanced Research (KSTAR) broke one record for fusion, it’s smashed it again, this time holding onto a churning whirlpool of 100 million degree plasma for a whole 30 seconds.

Though it’s well short of the 101 seconds set by the Chinese Academy of Sciences earlier this year, it remains a significant milestone on the road to cleaner, near-limitless energy that could transform how we power our society.

Here’s why it’s so important.

A South Korean Artificial Sun Reactor Just Broke a Nuclear Fusion Record

Posted by in category: nuclear energy

We’re a step closer to limitless energy. The Korea Institute of Fusion Energy has set a new record by running at one million degrees and maintaining super-hot plasma for 30 seconds, beating its own previous record by 10 seconds, a report by New Atlas reveals.

The tokamak reactor used for the record run is the Korea Superconducting Tokamak Advanced Research (KSTAR), which is also known as South Korea’s artificial sun.

KSTAR fusion reactor sets record with 30-second plasma confinement

Posted by in category: nuclear energy

Scientists are exploring nuclear fusion technology through various experimental devices, and a popular design for this pursuit of clean, practically inexhaustible energy is known as the tokamak. An exciting example of these donut-shaped reactors can be found at the Korea Institute of Fusion Energy, where scientists have reportedly set a new record by maintaining super-hot plasma for 30 seconds.

The idea behind fusion power is to recreate the processes that take place inside the Sun. Huge gravitational forces combine with intense heat and pressure to produce a plasma, in which nuclei smash into each other at high velocity to form helium and release energy.

Tokamaks are designed to recreate this process here on Earth with a series of coils placed around a torus-shaped reactor, magnetically confining plasma heated to millions of degrees for long enough for the fusion of nuclei to occur. Many of these experimental devices are in operation around the world, and the Korea Superconducting Tokamak Advanced Research (KSTAR) reactor is one making some promising strides.
