Why is division better than merger

In nuclear fusion, two atomic nuclei fuse to form a new nucleus. Nuclear fusion is the reason why the sun also radiates energy. It is a giant plasma ball, which consists mainly of hydrogen. A constant fusion fire blazes inside the sun. The hydrogen atomic nuclei fuse to form helium and huge amounts of energy are released.

Scientists are trying to recreate this process in fusion reactors. With the hydrogen types deuterium and tritium, a helium core and a lot of energy are to be generated at the same time. This requires temperatures of up to 100 million degrees Celsius in the fusion reactor. In such a reactor, one gram of fuel would be enough to generate the amount of energy that today requires eleven tons of coal.

Another advantage: the fusion fuels are relatively cheap and are found in abundance all over the world. The researchers also expect the fusion reactors to have favorable environmental and safety properties.

The problem with the previous nuclear fusion facilities is that they consume more energy than they generate. In Greifswald it was at least possible to bring about a merger over ten seconds. Energy production over 30 minutes should follow in the foreseeable future. However, it will take many years before continuous operation.

The international research project ITER, in which the EU, the USA, Russia, China, South Korea and India are also involved, is also estimated to go into operation in 2025 at the earliest. Commissioning was originally planned for 2016. It is still unclear whether and when the dream of nuclear fusion energy will come true. Meanwhile, the joke of the "fusion constant" has established itself among critics. Regardless of when you ask about it - it still takes "40 to 50 years" for a fusion device to operate continuously.
