Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achieved

In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature of the core of the sun. Zap Energy's unique...

Apple versus donut: How the shape of a tokamak impacts the limits of the edge of the plasma

Harnessing energy from plasma requires a precise understanding of its behavior during fusion to keep it hot, dense and stable. A new theoretical model about a plasma's edge, which can become unstable and bulge, brings the prospect of commercial fusion power closer to reality.

First Light Fusion Makes Progress Towards an Economical Working Fusion Reactor | NextBigFuture.com

First Light Fusion is developing an inertial fusion with a pulsed process. They fire physical projectiles at high speeds like 40 kilometers per second to

Machine 4 will have a stored electrical energy of about 100 megajoules with the capability of launching projectiles at 60 kms per second. This speed on impact inside the target will accelerate to about 200kms per second as a result of First Light’s exclusive amplifier technology.

First Light is aiming for net energy gain with Machine 4 with fuel gain of 100 or more. This machine is the building block for the pilot power plant, validating First Light’s simulation codes, while de-risking the design of high-gain targets for power production.

They are aiming for a power plant producing ~150 MW of electricity, firing once every 30 seconds, and costing less than $1 billion.

Xcimer lands $100M to build fusion energy prototype

Xcimer lands $100M to build fusion energy prototype​

"...the startup’s plan is to leverage laser technology originally conceived as part of the US Strategic Defense Initiative (aka “Star Wars” program) of the 1980s, using 248 nm-emitting KrF sources that have since played a key role in semiconductor manufacturing as the light source in deep-ultraviolet lithography systems.

“Xcimer’s laser architecture will produce up to ten times higher laser energy at ten times higher efficiency and over 30 times lower cost per joule than the NIF laser system that achieved fusion scientific breakeven in December 2022,” it claims, with CEO Conner Galloway..."
