Nuclear Fusion

The US Department of Energy and its National Nuclear Security Administration have announced the first-ever achievement of fusion ignition. The breakthrough should "pave the way for advancements in national defense and the future of clean power."

Having achieved a self-heating “burning plasma” in the quest for producing clean, limitless energy using nuclear fusion, on closer inspection of that plasma researchers have discovered strange, unexplained behavior of ions within it.

It seems China's Chang'E-5 robotic Moon mission has discovered more than water on the lunar surface. Scientists have confirmed the discovery of a new mineral, a transparent crystal named Changesite-(Y), as well as a promising potential fusion fuel.

Some fusion projects aim to create hundred-million degree working temperatures in magnetically confined plasma. The CEO of TAE Technologies tells us his team's aiming for 10 times that temperature, targeting cheaper, easier and safer boron fuel.

Nuclear fusion is an incredibly complex scientific problem that researchers are coming at from all sorts of angles, and company Zap Energy is starting to make waves through one of the lesser-known approaches.

While stellarator fusion reactors have conventionally featured irregularly shaped magnetic coils, scientists have now developed simpler and straighter versions they say can offer some important benefits.

Scientists have developed a sensor made of incredibly thin strands of sapphire that can withstand extreme heat and radiation, and possibly be put to work in the harsh environment of nuclear fusion reactors and enable more streamlined air travel.

A UK company says it's demonstrated fusion in record time, on a shoestring US$59 million budget, using an innovative new approach that embeds fuel pellets in tiny, falling cube targets, then shoots projectiles at them at 19 times the speed of sound.

Australian nuclear fusion company HB11 says its disruptive laser-powered reactor design has demonstrated results "many orders of magnitude higher than those reported by any other fusion company," without requiring multi-million degree temperatures.

Oxford-based UK tech firm Tokamak Energy has reached a milestone in privately-funded fusion research after its ST-40 spherical tokamak reactor reached a temperature of 100 million °C (180 million °F), the threshold for commercial fusion energy.

A new technology representing a "revolutionary change" in how magnets are made for tokamak reactors could form a key piece of the nuclear fusion power puzzle, by facilitating the type of sustained streams of plasma needed for it to become a reality.

DeepMind has lent its AI know-how to the quest for nuclear fusion. Through a partnership with scientists at EPFL, the company has developed an AI algorithm that can generate control strategies to create and maintain different plasma configurations.
