Nuclear power is going portable in the form of relatively lightweight, cost-effective microreactors. A team of former SpaceX engineers is developing the “world’s first portable, zero-emissions power source” that can bring power to remote areas and also allows for quick installation of new units in populated areas, a press statement revealed.
Last year, the team secured $1.2 million in funding from angel investors for their startup Radiant to help develop its portable nuclear microreactors, which are aimed at both commercial and military applications.
Could combining solar panels plus farming be a viable solution to the growing demand for food production and energy demand? Let’s take a closer look at electrifying our crops (not literally electrifying crops) … well, adding solar to our farm land as well as some of the side benefits and challenges it creates.

It sounds like a scene from a spy thriller. An attacker gets through the IT defenses of a nuclear power plant and feeds it fake, realistic data, tricking its computer systems and personnel into thinking operations are normal. The attacker then disrupts the function of key plant machinery, causing it to misperform or break down. By the time system operators realize they’ve been duped, it’s too late, with catastrophic results.
The scenario isn’t fictional; it happened in 2,010 when the Stuxnet virus was used to damage nuclear centrifuges in Iran. And as ransomware and other cyberattacks around the world increase, system operators worry more about these sophisticated “false data injection” strikes. In the wrong hands, the computer models and data analytics—based on artificial intelligence—that ensure smooth operation of today’s electric grids, manufacturing facilities, and power plants could be turned against themselves.
Purdue University’s Hany Abdel-Khalik has come up with a powerful response: To make the computer models that run these cyberphysical systems both self-aware and self-healing. Using the background noise within these systems’ data streams, Abdel-Khalik and his students embed invisible, ever-changing, one-time-use signals that turn passive components into active watchers. Even if an attacker is armed with a perfect duplicate of a system’s model, any attempt to introduce falsified data will be immediately detected and rejected by the system itself, requiring no human response.
“The twisted coils are the most expensive and complicated part of the stellarator and have to be manufactured to very great precision in a very complicated form,” physicist Per Helander, head of the Stellarator Theory Division at Max Planck and lead author of the new paper, told Princeton Plasma Physics Laboratory News.
The new design offers a simpler approach by instead using permanent magnets, whose magnetic field is generated by the internal structure of the material itself. As described in an article published by Nature, Zarnstorff realized that neodymium–boron permanent magnets—which behave like refrigerator magnets, only stronger—had become powerful enough to potentially help control the plasma in stellarators.
Advanced Nuclear Power Advocacy For Humanity — Eric G. Meyer, Founder & Director, Generation Atomic
Eric G. Meyer is the Founder and Director of Generation Atomic (https://generationatomic.org/), a nuclear advocacy non-profit which he founded after hearing about the promise of advanced nuclear reactors, and he decided to devote his life to saving and expanding the use of atomic energy.
Eric worked as an organizer on several political, union, and issue campaigns while in graduate school for applied public policy, taking time off to attend the climate talks in Paris and sing opera about atomic energy.
Eric began his full time nuclear work in May of 2016 with Environmental Progress by organizing marches, rallies, and trainings in California, New York, and Illinois, before leaving to found Generation Atomic in late 2016.
In only a short period of time, Generation Atomic has made significant progress in the world of nuclear advocacy. Over the last year they’ve held several advocacy trainings at conferences, Marched for Science, talked to over tens of thousands voters, and carried the banner for nuclear energy at the climate talks in Morocco, Germany, and Poland.
While wind turbine and solar power platforms are beginning to take to the sea, another, more established form of power might also avoid hiking real estate costs.
A Copenhagen-based startup just raised funding to the sum of eight figures in Euros to begin construction of a new kind of cheap, flexible, portable, and unyieldingly safe nuclear reactor, according to a press release shared by the company, Seaborg Technologies.
And, crucially, the timeline for global deployment will shatter conventional paradigms in the energy industry.
How close is nuclear fusion to break-even? If you trust the headlines we’re getting close and the international project ITER is going to be the first to produce energy from fusion power. But not so fast. Scientists have, accidentally or deliberately, come to use a very misleading quantity to measure their progress. Unfortunately we’re much farther away from generating fusion power than the headlines suggest.
Editor’s note, 6/28/21, 3:35 PM: The article was updated to clarify that Natrium features a sodium‐cooled fast reactor and not a type of molten salt reactor, as previously reported.
A nuclear power startup founded by Bill Gates has announced plans to build a new kind of nuclear reactor at a retiring coal plant in Wyoming.
This reactor will be the first real-world demonstration of the startup’s technology, which could help power the world — without warming the climate.
Stellarators, twisty magnetic devices that aim to harness on Earth the fusion energy that powers the sun and stars, have long played second fiddle to more widely used doughnut-shaped facilities known as tokamaks. The complex twisted stellarator magnets have been difficult to design and have previously allowed greater leakage of the superhigh heat from fusion reactions.
Now scientists at the Max Planck Institute for Plasma Physics (IPP), working in collaboration with researchers that include the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL
The U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) is a collaborative national laboratory for plasma physics and nuclear fusion science. Its primary mission is research into and development of fusion as an energy source for the world.
Past and present nuclear activities (energy, research, weapon tests) have increased the urgency to understand the behavior of radioactive materials in the environment. Nuclear wastes containing actinides (e.g. plutonium, americium, curium, neptunium…) are particularly problematic as they remain radioactive and toxic for thousands of years.
Lawrence Livermore National Laboratory (LLNL) scientists and collaborators proposed a new mechanism by which nuclear waste could spread in the environment.
The new findings, that involve researchers at Penn State and Harvard Medical School, have implications for nuclear waste management and environmental chemistry. The research is published in the Journal of the American Chemical Society.
“This study relates to the fate of nuclear materials in nature, and we stumbled upon a previously unknown mechanism by which certain radioactive elements could spread in the environment,” said LLNL scientist and lead author Gauthier Deblonde. “We show that there are molecules in nature that were not considered before, notably proteins like ‘lanmodulin’ that could have a strong impact on radioelements that are problematic for nuclear waste management, such as americium, curium, etc.”
