Using relativistic effects for laser fusion: A new approach for clean power

Posted by in category: nuclear energy

A team of researchers at Osaka University has investigated a new method for generating nuclear fusion power, showing that the relativistic effect of ultra-intense laser light improves upon current “fast ignition” methods in laser-fusion research to heat the fuel long enough to generate electrical power. These findings could provide a spark for laser fusion, ushering in a new era of carbonless energy production.

Current nuclear power uses the fission of heavy isotopes, such as uranium, into lighter elements to produce power. Yet, this fission power has major concerns, such as spent fuel disposal and the risk of meltdowns. A promising alternative to fission is . Like all stars, our sun is powered by the of light isotopes, notably hydrogen, into heavier elements. Fusion has many advantages over fission, including the lack of hazardous waste or risk of uncontrolled nuclear reactions.

However, getting more energy out of a fusion reaction than was put into it has remained an elusive goal. This is because hydrogen nuclei strongly repel each other, and fusion requires and pressure conditions—like those found in the interior of the sun, for instance—to squeeze them together. One method, called “inertial confinement” uses extremely high-energy laser pulses to heat and compress a fuel pellet before it gets the chance to be blown apart. Unfortunately, this technique requires extremely precise control of the laser’s energy so that the compression shock waves all arrive at the center simultaneously.

Iran discovers new oil field with over 50 billion barrels

Posted by in category: nuclear energy

TEHRAN, Iran (AP) — Iran has discovered a new oil field in the country’s south with over 50 billion barrels of crude, its president said Sunday, a find that could boost the country’s proven reserves by a third as it struggles to sell energy abroad over U.S. sanctions.

The announcement by Hassan Rouhani comes as Iran faces crushing American sanctions after the U.S. pulled out of its nuclear deal with world powers last year.

Rouhani made the announcement in a speech in the desert city of Yazd. He said the field was located in Iran’s southern Khuzestan province, home to its crucial oil industry.

Sustainable supply of minerals and metals key to a low-carbon energy future

Posted by in categories: governance, nuclear energy, sustainability, transportation

The global low-carbon revolution could be at risk unless new international agreements and governance mechanisms are put in place to ensure a sustainable supply of rare minerals and metals, a new academic study has warned.

The amount of cobalt, copper, lithium, cadmium, and rare earth elements needed for solar photovoltaics, batteries, electric vehicle (EV) motors, wind turbines, fuel cells, and nuclear reactors will likely grow at a rapid pace in the upcoming years. Even if alternatives are found for one metal, there will be reliance on another as the scope of possibilities is inherently limited by physical and chemical properties of elements.

However, with global supplies often heavily monopolized by a single country, confronted by social and environmental conflict, or concentrated in poorly functioning markets, there is a real possibility that a shortage of minerals could hold back the urgent need for a rapid upscaling of low-carbon technologies. In some cases, markets are providing misleading signals to investors that can lead to poor decisions. In other cases, the countries or regions supplying minerals are politically unstable.

From dream to reality: Russia’s ‘Silicon Valley’ to mark 10-year anniversary with new projects

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

Russia’s Skolkovo innovation center, which is marking 10 years since its founding, has ambitious plans for 2020 and beyond to continue promoting technology and helping small innovative startups grow into profitable companies.

Skolkovo Technopark was built from scratch almost a decade ago to create a platform for research and innovation in key spheres such as energy, IT, space, biomedicine, and nuclear technology. Now the complex has facilities spread around 800,000 square meters and hosts around 500 startups, while there are an additional 1,500 enterprises beyond its campus. Skolkovo hosts around 50 research centers employing more than 15,000 people.

Laser-heated nanowires produce micro-scale nuclear fusion

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

Nuclear fusion, the process that powers our sun, happens when nuclear reactions between light elements produce heavier ones. It’s also happening — at a smaller scale — in a Colorado State University laboratory.

Using a compact but powerful laser to heat arrays of ordered nanowires, CSU scientists and collaborators have demonstrated micro-scale nuclear fusion in the lab. They have achieved record-setting efficiency for the generation of neutrons — chargeless sub-atomic particles resulting from the fusion process.

Their work is detailed in a paper published in Nature Communications (“Micro-scale fusion in dense relativistic nanowire array plasmas”), and is led by Jorge Rocca, University Distinguished Professor in electrical and computer engineering and physics. The paper’s first author is Alden Curtis, a CSU graduate student.

5G, AI, data privacy and mass surveillance — 12 biggest tech policy challenges India will have to face in 2020

Posted by in categories: cybercrime/malcode, government, internet, nuclear energy, policy, robotics/AI, surveillance

As access to the internet grows, so do the risks associated with being online. Cybersecurity threats are on the rise as data hackers find new ways to breach through firewalls. Earlier this year bad actors were able to gain access to the administrative serves of India’s largest nuclear power plant with a simple phishing email.

The government want to increase its cyber might to ward off such hazards but experts feel some of its policies might do the exact opposite.


2020 will be a busy year for India with the 5G spectrum auction still pending, Personal Data Protection Bill under discussion, and the deadline for social.

This Powder—Not Gas—Could Rescue Nuclear Fusion

Posted by in category: nuclear energy

Researchers at Princeton University have found a way to make a tokamak nuclear fusion reactor safer using insulating boron powder. The new research appears in the IAEA journal Nuclear Fusion and comes from Princeton’s U.S. Department of Energy-funded Princeton Plasma Physics Laboratory (PPPL).

A tokamak, like the huge one that will reach 200 million Celsius in China next year, is a nuclear fusion plasma reactor where extremely hot, charged plasma spins and generates virtually limitless energy. The Princeton research examines the way boron powder can prevent one of the fundamental flaws in existing plasma reactor technology.

Russia to track EARTH-THREATENING asteroids from robot-inhabited nuclear-powered polar Moon base

Posted by in categories: government, nuclear energy, robotics/AI, solar power, space, sustainability

Moon’s southern pole will be a good spot for an observatory that together with space-based telescopes help find dangerous asteroids. Russia plans to build one as part of an ambitious lunar base project.

Conquering the moon is on the Russian space agency’s to-do list for the not-so-distant future. Roscosmos is currently working on a comprehensive plan that the Russian government wants to see before allocating any money for it. Part of a permanent Russian base envisioned on the Moon will be given to an observatory that will serve as part of a “global system for tracking asteroid and comet threats,” a senior Roscosmos official said in a recent interview.

“The location selected for the base is southern pole of the moon. It has favorable relief and conditions: enough light for solar panels, constantly shadowed craters with ice reserves for fuel and raw material,” Aleksandr Bloshenko explained.
