The article doesnt mention US efforts, such as Lawrence Livermore National Laboratory.
Lawrence Livermore has been doing this for the longest time I can think of.
Here is an article from 2008:
EXCERPT:
While it has seemed an impossible goal for nearly 100 years, scientists now believe that they are on brink of cracking one of the biggest problems in physics by harnessing the power of nuclear fusion, the reaction that burns at the heart of the sun.
In the spring, a team will begin attempts to ignite a tiny man-made star inside a laboratory and trigger a thermonuclear reaction.
Its goal is to generate temperatures of more than 100 million degrees Celsius and pressures billions of times higher than those found anywhere else on earth, from a speck of fuel little bigger than a pinhead. If successful, the experiment will mark the first step towards building a practical nuclear fusion power station and a source of almost limitless energy.
At a time when fossil fuel supplies are dwindling and fears about global warming are forcing governments to seek clean energy sources, fusion could provide the answer. Hydrogen, the fuel needed for fusion reactions, is among the most abundant in the universe. Building work on the £1.2 billion nuclear fusion experiment is due to be completed in spring.
Scientists at the National Ignition Facility (NIF) in Livermore, nestled among the wine-producing vineyards of central California, will use a laser that concentrates 1,000 times the electric generating power of the United States into a billionth of a second.
The result should be an explosion in the 32ft-wide reaction chamber which will produce at least 10 times the amount of energy used to create it.
“We are creating the conditions that exist inside the sun,” said Ed Moses, director of the facility. “It is like tapping into the real solar energy as fusion is the source of all energy in the world. It is really exciting physics, but beyond that there are huge social, economic and global problems that it can help to solve.”
Probably because the US program is a bottomless money pit.
Indees. Tokamak is not the only way to produce fusion. Amongst others are particle colliders, laser arrays, x-ray lasers and electically driven implosions of wires at temperature high enough to create x-rays.
I once sold Taiwan products to that place...
