Nuclear fusion startup test fires plastic waste-powered rocket

"...A UK company with lofty aspirations around sustainable space travel has test-fired a rocket engine powered in part by plastic waste. Pulsar Fusion's hybrid rocket engine is part of an ambitious journey that also involves the development of nuclear fusion technology for high-speed propulsion, which could cut travel times to Mars in half. The idea of incorporating recycled plastic waste into hybrid rocket fuels is something we have seen explored before..."

KSTAR fusion reactor sets record with 30-second plasma confinement

"...Scientists are exploring nuclear fusion technology through various experimental devices, and a popular design for this pursuit of clean, practically inexhaustible energy is known as the tokamak. An exciting example of these donut-shaped reactors can be found at the Korea Institute of Fusion Energy, where scientists have reportedly set a new record by maintaining super-hot plasma for 30 seconds. The idea behind fusion power is to recreate the processes that take place inside the Sun..."

World's strongest fusion magnet brings new power to nuclear pursuit

"...In the field of nuclear fusion some are going big with their pursuit of clean, inexhaustible energy, like those piecing together the seven-story building to house ITER, the world's largest tokamak reactor. Others, meanwhile, are working on more compact and affordable designs in an attempt to edge the technology forward. A new breakthrough from MIT scientists demonstrates how some of the biggest advances might just come from these projects that are smaller in stature, with the team revealing a record-setting superconductive magnet, the most powerful of its type in the world..."

Wendelstein 7-X fusion reactor on path to plasma twice as hot as the Sun

"...The Wendelstein 7-X stellarator is an experimental nuclear fusion reactor designed to bring us closer to the prospect of clean, limitless energy, and since producing its first plasma in 2015 we've seen it take steady and significant steps toward that aim. Physicists have just confirmed another "major advance" that could see the reactor host plasma twice as hot as the Sun's core as a result of efforts to address inherent energy losses in the design. Stellarators stand apart from the more common, symmetrical doughnut-shaped tokamak fusion reactors as hugely complex structures full of twists and turns..."

Celebrating stories of Ontarians: Roberta Bondar and Art McDonald, Members of the Order of Ontario

"...“Nuclear fusion powers the sun; it’s being attempted on Earth as a major green energy source,” says McDonald. “We have proven that the calculations of how the sun burns are accurate. So it’s the engineering that needs to be sorted out to create a very substantial green energy source that uses water from the oceans and can help our climate change efforts..."

China claims new fusion record with its

"...China's Experimental Advanced Superconducting Tokamak (EAST) is one of a number of promising nuclear fusion research devices in operation around the world, and over the past few years we've seen it take some impressive steps forward. Chinese state media is now reporting that scientists working on the project have achieved a new world record by holding plasma of 120 million degrees Celsius for 101 seconds in their latest round of experiments, edging closer to the long-pursued goal of clean and limitless energy. The idea behind nuclear fusion research is to recreate the process that the Sun uses to produce monumental amounts of energy, where intense heat and pressure combine to produce plasma in which atomic nuclei fuse at incredible velocities..."

New findings help in protecting divertor without degrading core plasma

"...The high-power and long-pulse operation of tokamak will cause excessive particle flux and heat load on the divertor target plate. The surface of the target plate will be subject to intense sputtering, and the thermal load of the target plate will exceed the material/component limit..."

Tracking the progress of fusion power through 60 years of neutral particle analysis

"...As the world's energy demands grow, so too does growing concern over the environmental impact of power production. The need for a safe, clean, and reliable energy source has never been clearer. Fusion power could fulfil such a need..."

Four ways to fusion: The pros and pitfalls of our nuclear power pursuit

"...For nearly a century, scientists have been tantalized by the prospect of attaining an inexhaustible source of energy through nuclear fusion. Unfortunately, engineering a controlled environment where atomic nuclei can continuously fuse under extreme pressure and temperature to produce energy that we can capture is very difficult, but that doesn't mean exciting advances aren't being made. Here we take a look at some of the different approaches to nuclear fusion, and the reasons why some appear more promising than others..."

Bottling the world's coldest plasma

"..."To understand how the solar wind interacts with the Earth, or to generate clean energy from nuclear fusion, one has to understand how plasma -- a soup of electrons and ions -- behaves in a magnetic field," said Rice Dean of Natural Sciences Tom Killian, the corresponding author of a published study about the work in Physical Review Letters..."
