Both @swurzel and @ScottCHsu have done a great job tracking decades of progress toward net fusion energy — more power out than in. That goal, denoted Q>1, is a key step toward fusion energy commercialization. The researchers’ 2022 paper summarizes decades of results from dozens of machines.
Now Wurzel and Hsu are updating their research with newer results like the National Ignition Facility’s successful demonstrations. Projected results from our own SPARC machine, which we detailed in our own physics basis research papers, appear on their plots. We plan to push first for Q>1, but the machine is designed to reach Q=11.
For anyone who wants to track fusion energy progress, this unbiased assessment rises above much of the noise. Kudos to these researchers for helping it keep pace with our fast-moving industry.

The horizontal axis is the ion temperature, measured in kilo-electron volts (keV). 1 keV = 11.6 million degrees. Under the assumptions made in this plot, high performance requires high temperatures, period.

Now that NIF has crossed that threshold, we've created a new plot of scientific gain over time. You can see the results from the 1990s in tokamaks like JET and TFTR and the recent rapid progress being made at the NIF. The inset is the same data on log-linear axes.

The vertical axis is the product of two quantities, plasma density and how long energy stays in the system.
These two can be traded off! In magnetic confinement schemes the density is low and energy stays in the system for a longer time compared to inertial confinement (usually done with lasers) where the density is much higher but the time energy stays in the system is much lower.
We call the product of these two quantities the Lawson parameter.

Senator Manchin highlighted recent global trends in equity investments to fusion companies with a Fusion Energy Base graph in today's Full Committee Hearing to Examine Fusion Energy Technology Development. Given the interest in this graph, I've run the numbers through September 2024 and made an updated graph in the article linked below.
