New fusion tech utilizes lasers to bypass sun-like temps and get rid of nuclear waste

Posted by in categories: nuclear energy, particle physics

You know what this world needs now… aside from love, sweet love, of course? Less nuclear waste. But it also seemingly needs more and more power, which nuclear would be great at providing, if not for all that pesky waste and those darn radioactive meltdowns that can happen when you go around splitting atoms (fission). Which is where nuclear fusion was supposed to help out, but generating Sun-like temperatures to recreate the processes that power our Earth-powering star have kept that technology at bay.

Well, we may be a lot closer to utilizing the power of fusion, thanks to the revolutionary thinking of HB11, a company that recently secured patents in the U.S., Japan, and China for just that kind of forward thinking technology. And if all goes according to plan, it could just change the world of electricity generation as we know it.

Design of the W7-X fusion device enables it to overcome obstacles, scientists find

Posted by in categories: nuclear energy, physics

A key hurdle facing fusion devices called stellarators—twisty facilities that seek to harness on Earth the fusion reactions that power the sun and stars—has been their limited ability to maintain the heat and performance of the plasma that fuels those reactions. Now collaborative research by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the Max Planck Institute for Plasma Physics in Greifswald, Germany, have found that the Wendelstein 7-X (W7-X) facility in Greifswald, the largest and most advanced stellarator ever built, has demonstrated a key step in overcoming this problem.

Cutting-edge facility

The cutting-edge facility, built and housed at the Max Planck Institute for Plasma Physics with PPPL as the leading U.S. collaborator, is designed to improve the performance and stability of the plasma—the hot, charged state of matter composed of free electrons and atomic nuclei, or ions, that makes up 99 percent of the visible universe. Fusion reactions fuse ions to release massive amounts of energy—the process that scientists are seeking to create and control on Earth to produce safe, clean and virtually limitless power to generate electricity for all humankind.

Patents Secured for Revolutionary Nuclear Fusion Technology

Posted by in categories: materials, nuclear energy

Scientists in Australia are making some astonishing claims about a new nuclear reactor technology. Startup HB11, which spun out of the University of New South Wales, has applied for and received patents in the U.S., Japan, and China so far. The company’s technology uses lasers to trigger a nuclear fusion reaction in hydrogen and boron—purportedly with no radioactive fuel required. The secret is a cutting-edge laser and, well, an element of luck.

The laser doesn’t heat the materials. Instead, it speeds up the hydrogen to the point where it (hopefully) collides with the boron to begin a reaction.

Fusion Startup Claims Breakthrough Will Provide “Unlimited” Energy

Posted by in categories: innovation, nuclear energy

The process even skips the “need for a heat exchanger or steam turbine generator” and can feed an electrical flow “almost directly into an existing power grid,” according to the company’s statement.

No nuclear waste, no steam, zero chance of a nuclear meltdown. It almost sounds too good to be true — but the startup still has a lot to prove. McKenzie admitted himself he doesn’t know if or when the startup’s idea could be turned into a commercial reality.

“I don’t want to be a laughing stock by promising we can deliver something in 10 years, and then not getting there,” he told New Atlas.

Radical hydrogen-boron reactor leapfrogs current nuclear fusion tech

Posted by in categories: nuclear energy, particle physics

“We are sidestepping all of the scientific challenges that have held fusion energy back for more than half a century,” says the director of an Australian company that claims its hydrogen-boron fusion technology is already working a billion times better than expected.

HB11 Energy is a spin-out company that originated at the University of New South Wales, and it announced today a swag of patents through Japan, China and the USA protecting its unique approach to fusion energy generation.

Fusion, of course, is the long-awaited clean, safe theoretical solution to humanity’s energy needs. It’s how the Sun itself makes the vast amounts of energy that have powered life on our planet up until now. Where nuclear fission – the splitting of atoms to release energy – has proven incredibly powerful but insanely destructive when things go wrong, fusion promises reliable, safe, low cost, green energy generation with no chance of radioactive meltdown.

Particle Tracking at CERN with Machine Learning

Posted by in categories: information science, nuclear energy, particle physics, robotics/AI

TrackML was a Kaggle competition in 2018 with $25 000 in cash prizes where the challenge was to reconstruct particle tracks from 3D points left in silicon detectors. CERN (the European Organization for Nuclear Research) provided data over particles collision events. The rate at which they occur over there is in the neighborhood of hundreds of millions of collisions per second, or tens of petabytes per year. There is a clear need to be as efficient as possible when sifting through such an amount of data, and this is where machine learning methods may be of help.

Particles, in this case protons, are boosted to high energies inside the Large Hadron Collider (LHC) — each beam can reach 6.5 TeV giving a total of 13 TeV when colliding. Electromagnetic fields are used to accelerate the electrically charged protons in a 27 kilometers long loop. When the proton beams collide they produce a diverse set of subatomic byproducts which quickly decay, holding valuable information for some of the most fundamental questions in physics.

Detectors are made of layers upon layers of subdetectors, each designed to look for specific particles or properties. There are calorimeters that measure energy, particle-identification detectors to pin down what kind of particle it is and tracking devices to calculate the path of a particle. [1] We are of course interested in the tracking, tiny electrical signals are recorded as particles move through those types of detectors. What I will discuss is methods to reconstruct these recorded patterns of tracks, specifically algorithms involving machine learning.

8 Year-Old Mexican Girl Invents A Solar Water Heater & Wins Nuclear Science Prize

Posted by in categories: nuclear energy, robotics/AI, science, sustainability

Innovation comes from all ages, and this is further seen in the story of Xóchitl Guadalupe Cruz, an eight-year-old girl from Chiapas, Mexico who invented an entirely solar-powered device for heating water. The impact her invention could have on others around the world is immense, and this has inspired the UNAM’s (National Autonomous University of Mexico) Institute of Nuclear Sciences to award her.

To those in developed countries, her invention may not seem all that revolutionary as access to warm or hot water is commonplace, but for those in many other areas of the world, including her town in Mexico, this would be a luxury.
