Nuclear Fusion Power Without Regular Tokamaks Or Stellarators:
When it comes to nuclear fusion, the most well-known reactor type today is no doubt the tokamak, due to its relatively straight-forward concept of plasma containment. That's not to say that there aren't other ways to accomplish nuclear fusion in a way that could conceivably be used in a commercial power plant in the near future.
As we covered previously, another fairly well-known type of fusion reactor is the stellarator, which much like the tokamak, has been around since the 1950s. There are other reactor types from that era, like the Z-pinch, but they seem to have all fallen into obscurity. That is not to say that research on Z-pinch reactors has ceased, or that other reactor concepts — some involving massive lasers — haven't been investigated or even built since then.
In this article we'll take a look at a range of nuclear fusion reactor types that definitely deserve a bit more time in the limelight.

Well, I was doing a lot of original research looking through budget proposals to try and figure out where fusion research is actually allocated.
But I finally found a number someone else put together: 631 million 2019 dollars [aip.org], which is apparently 551 million in 2013 dollars.
