Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One of the problems is how to overcome the strong electrical repulsion between atomic nuclei which requires high energies to make them fuse. But fusion could be initiated at lower energies with electromagnetic fields that are generated, for example, by state-of-the-art free electron lasers emitting X-ray light. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) describe how this could be done in the journal Physical Review C.

During nuclear fusion two atomic nuclei fuse into one new nucleus. In the lab this can be done by particle accelerators, when researchers use fusion reactions to create fast free neutrons for other experiments. On a much larger scale, the idea is to implement controlled fusion of light nuclei to generate power – with the sun acting as the model: its energy is the product of a series of fusion reactions that take place in its interior.

For many years, scientists have been working on strategies for generating power from fusion energy. “On the one hand we are looking at a practically limitless source of power. On the other hand, there are all the many technological hurdles that we want to help surmount through our work,” says Professor Ralf Schützhold, Director of the Department of Theoretical Physics at HZDR, describing the motivation for his research.

China has developed its own artificial sun that uses nuclear fusion to generate clean energy as much as 10 suns! China has recently completed the construction of this reactor and the operations for the same are expected to commence starting sometime in 2020.

Ok… which one of y’all is this?

UPDATE 3: The man reportedly told bomb squad that he sustained “radio frequency burns” while working on a “quantum physics generator” in his garage, according to Battalion Chief Steve Martin, the Columbus Division of Fire spokesman, speaking to the Columbus Dispatch.

“We have no reason to believe that he was trying to make anything that would do anyone any harm,” Martin added.

Robert Adams updated the work on a phase 2 Pulsed Fission-Fusion (PuFF) Propulsion Concept. Robert works at the NASA Marshall Space Flight Center. This system should be able to achieve 15 kW/kg and 30,000 seconds of ISP. This will be orders of magnitude improvement over competing systems such as nuclear electric, solar electric, and nuclear thermal propulsion that suffer from lower available power and inefficient thermodynamic cycles. Puff will meet an unfilled capability needed for manned missions to the outer planets and vastly faster travel throughout the solar system.

A tiny lithium deuteride and uranium 235 pellet will be fired into a shell of structure that will complete a circuit and generate high voltages and pressures that will compress the pellet and cause fission and fusion to occur.

Heat from fission fuel increases the reactivity of the fusion fuel and the neutron flux may breed additional fuel to fuse. Additionally, the neutron flux from the fusion fuel will induce fission. This coupling can drastically reduce the driving energy required to initiate the burn and drastically improve output. This concept has been examined in the past by Winterberg and is being investigated in support of a Pulsed Fission-Fusion (PuFF) engine concept at Marshall Space Flight Center and the University of Alabama in Huntsville.

A nuclear-powered bullet train that was equipped with amenities more appropriate to a cruise ship, it had luxuries such as swimming pools and shopping centers.

Supertrain was an American television drama/adventure series that ran on NBC from February 7 to May 5, 1979. Nine episodes were made. Most of the cast of a given episode were guest stars. The production was elaborate, with huge sets and a high-tech model train for outside shots.

On February 7th, 1979, thousands of Americans were introduced to the Supertrain, which ran from New York to Los Angeles. Nuclear-powered, the super-wide-bodied train topped out at 190 miles per hour and boasted on-board luxuries like a swimming pool, a discotheque, a shopping center and a movie theater. It even had a dedicated on-board Social Director.

New research from the University of Rochester will enhance the accuracy of computer models used in simulations of laser-driven implosions. The research, published in the journal Nature Physics, addresses one of the challenges in scientists’ longstanding quest to achieve fusion.

In laser-driven inertial confinement fusion (ICF) experiments, such as the experiments conducted at the University of Rochester’s Laboratory for Laser Energetics (LLE), short beams consisting of intense pulses of light—pulses lasting mere billionths of a second—deliver energy to heat and compress a target of hydrogen fuel cells. Ideally, this process would release more energy than was used to heat the system.

Laser-driven ICF experiments require that many laser beams propagate through a plasma—a hot soup of free moving electrons and ions—to deposit their radiation energy precisely at their intended target. But, as the beams do so, they interact with the plasma in ways that can complicate the intended result.

Physicist plans to karate-chop them with super-fast blasts of light.

There are many directions we could go when it comes to the future of sustainable energy—but the UK made a bold move when it announced a huge investment (220 million pounds huge) in a prototype fusion power facility that could be functioning as a commercial power plant by 2040.
