China builds huge laser system for unlimited clean energy

Latest pictures from space reveal an enormous, x-shaped building that rises from the rocky terrain in southwestern China. Experts indicate that this is a big Research facility for Core fusion acts, which could be a sign that China takes an important step forward when using this future -oriented energy source.

It could also indicate that China is driving its developments in the field of nuclear weapons. Decker Eveleth, analyst at the US research organization CNA Corporation, has been pursuing this facility for years. In 2020, a US official published pictures that show various potential Chinese nuclear locations, including the location near Mianyang in the province of Sichuan.

construction progress and technical details

At this point, the system was more or less a "dirt stain", says Eveleth in an interview with CNN. But after the removal of the covid-related restrictions, the construction accelerated. In the contract documents obtained, the project is described as a "laser fusion system". If it is actually a laser system, it offers a unique way to examine materials under extreme conditions. According to Brian Appleel, research employee at the Center for Inertial Fusion Studies at Imperial College London, scientists can create "pressure relationships, as they typically occur inside stars or in nuclear weapons."

process of the merger process

Eveleth explains that the four huge arms that can be seen in the satellite picture show "bays" that are able to fire lasers on the high central tower. In this tower there is a target chamber that contains hydrogen isotopes. The laser energy merges the hydrogen and creates an energy push in a process that is known as an ignition.

The advantages of core fusion

core fusion offers the tempting view of plenty of clean energy, without the problem of long -lasting radioactive waste connected to the nuclear fission, the current technology to produce nuclear energy. Countries and companies worldwide are in a race to master this technology.

USA and the race for fusion energy

The USA was a leader in this area for a long time. The National Ignition Facility (NIF) in California, which also uses laser ignition technology, achieved a significant breakthrough in fusion energy in 2022. In a global novelty, NIF scientists managed to achieve a successful core fusion with a net profit of energy (although the energy required for the laser was not taken into account).

china's ambitious plans

This was a great step forward in decades of striving to reproduce the reaction on earth that drives the sun and other stars. But the new facility in China could be a sign that China begins to take the lead in this technology. "This signals that you are working seriously on fusion research," said Melanie Windridge, CEO of Fusion Energy Insights, an organization to monitor the industry. "They act decisively, move quickly and bring things forward."

Potential influence on nuclear weapons research

Eveleth estimates that the research center in Mianyang will be around 50 % larger than the NIF in the USA and, as soon as it is complete, will probably be the largest system of its kind worldwide. This size could bring advantages. A larger laser enables higher pressures, and more material can be compressed, which could potentially increase the energy yield from fusion experiments. However, Appeals emphasizes that it is "extremely challenging" to achieve a successful fusion experiment itself with a very large laser.

conclusion and outlook

Experts warn that the facility also offers China the opportunity to research core weapons. Both China and the United States are parties of the comprehensive nuclear testing contract that prohibits nuclear explosions. The energy released by nuclear weapons is very difficult to simulate computers and other conventional methods. According to Eveleth, laser ignition systems can help by focusing high-performance lasers on different materials to simulate the conditions in the first microseconds after a nuclear explosion.

it is assumed that the Mianyang facility ultimately becomes a different type of merger system, a hybrid form made of fusion and fission reactor, this could be worrying. "If this turns out to be true, it is particularly alarming," says Andrew Holland, managing director of the Fusion Industry Association. This would amount to domestic Chinese technology and "probably more powerful than anything that concerns this kind in western countries."

Regardless of this, the facility is "clearly part of an ambitious program," said Holland in an interview with CNN. The United States is currently still in the leadership race, but "China is moving quickly" and has shown that it can progress much faster from the conception to completion than the government programs.

"It is time to invest," emphasizes Holland. "If the USA and its allies do not do that, China will win this race."
