Shoot for the Moon: Its Surface Contains a Pot of Gold

Posted by in categories: biotech/medical, military, nuclear energy, terrorism

Here’s a riddle: What do the Moon, nuclear weapons, clean energy of the future, terrorism, and lung disease all have in common?

The answer is helium-3, a gas that’s extremely rare on Earth but 100 million times more abundant on the Moon.

The capability to show anatomic details of the lungs and airways, and the ability to display functional imaging as a patient breathes, makes helium-3 MRI far better than the standard method of testing lung function. Called spirometry, this method tells physicians how the lungs function overall, but does not home in on particular areas that may be causing a problem. Plus, spirometry requires patients to follow instructions and hold their breath, so it is not great for testing young children with pulmonary disease.

Scientists gain an unprecedented view of irradiated nuclear fuel

Posted by in categories: materials, nuclear energy

In a feat requiring perseverance, world-leading technology, and no small amount of caution, scientists have used intense X-rays to inspect irradiated nuclear fuel. The imaging, led by researchers at Purdue University and conducted at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, revealed a 3D view of the fuel’s interior structure, laying the groundwork for better nuclear fuel designs and models.

Until now, examinations of uranium fuel have been limited to mostly surface microscopy or to various characterization techniques using mock versions that possess little radioactivity. But scientists want to know at a deeper level how the material changes as it undergoes fission inside a . The resulting insights from this study, which the Journal of Nuclear Materials published in August 2020, can lead to that function more efficiently and cost less to develop.

Storm in a cosmic teacup: A new paradigm for understanding plasma turbulence

Posted by in categories: nuclear energy, physics, space

On the path to writing his Ph.D. dissertation, Lucio Milanese made a discovery—one that refocused his research, and will now likely dominate his thesis.

Milanese studies , a gas-like flow of ions and electrons that comprises 99 percent of the visible universe, including the Earth’s ionosphere, interstellar space, the , and the environment of stars. Plasmas, like other fluids, are often found in a turbulent state characterized by chaotic, unpredictable motion, providing multiple challenges to researchers who seek to understand the cosmic universe or hope to harness burning plasmas for fusion energy.

Milanese is interested in what physicist Richard Feynman called “the most important unsolved problem of classical physics”—turbulence. In this case, the focus is plasma turbulence, its nature and structure.

Meet the father of the hydrogen-boron laser fusion reactor

Posted by in category: nuclear energy

Circa 2020 radiationless laser.

One of the world’s leading specialists in laser fusion, the Australian physicist Prof. Heinrich Hora, has proposed a new type of nuclear reactor which promises to provide highly-efficient, radioactivity-free generation of electric power, with virtually unlimited reserves of fuel. The design uses ultra-high-power, ultra-short-pulsed lasers to trigger fusion reactions between nuclei of hydrogen and boron. Hora believes that a prototype of his reactor could be running within the decade.

In the previous installments of this series, Jonathan Tennenbaum introduced readers to the new reactor concept and its fascinating scientific and technological background.

The thorium-powered car: Eight grams, one million miles

Posted by in categories: nuclear energy, transportation

A US company says it will have a nuclear-powered prototype vehicle on the road within two years.

Laser Power Systems from Connecticut is developing a method of propulsion that uses thorium to produce electricity to power a car engine.

Thorium is an element similar to uranium and because it is such a dense material it has the potential to produce massive amounts of heat.

Future interstellar rockets may use laser-induced annihilation reactions for relativistic drive

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

O,.o kaons in action for interstellar travel: D.

Interstellar probes and future interstellar travel will require relativistic rockets. The problem is that such a rocket drive requires that the rocket exhaust velocity from the fuel also is relativistic, since otherwise the rocket thrust is much too small: the total mass of the fuel will be so large that relativistic speeds cannot be reached in a reasonable time and the total mass of the rocket will be extremely large. Until now, no technology was known that would be able to give rocket exhaust at relativistic speed and a high enough momentum for relativistic travel. Here, a useful method for relativistic interstellar propulsion is described for the first time. This method gives exhaust at relativistic speeds and is a factor of at least one hundred better than normal fusion due to its increased energy output from the annihilation-like meson formation processes. It uses ordinary hydrogen as fuel so a return travel is possible after refuelling almost anywhere in space. The central nuclear processes have been studied in around 20 publications, which is considered to be sufficient evidence for the general properties. The nuclear processes give relativistic particles (kaons, pions and muons) by laser-induced annihilation-like processes in ultra-dense hydrogen H. The kinetic energy of the mesons is 1300 times larger than the energy of the laser pulse. This method is superior to the laser-sail method by several orders of magnitude and is suitable for large spaceships.
