Fusion and its problems.

The biggest technical problem in fusion seems simple. How to control plasma. Theoretically, that requires only. That the outermost layer of the plasma belt is at a higher energy level. Than the inner plasma that travels in Tokamak reactors. The higher energy level. At the outermost layer of that plasma. Traps energy in the plasma ring. 

When fusion begins. Energy. That comes from the middle of the plasma ring. It will break the plasma. So, fusion starts in the middle of the plasma ring. That plasma ring travels in a magnetic tube. That keeps it away from the walls of the Tokamak reactors. That plasma is hotter than the Sun.  The system must increase the temperature to compensate for the Sun’s gravitational effect. 

This means the reactor compresses plasma in the middle of the magnetic tube. And that causes another problem. When. fusion starts. Ignition pushes ions, or high-temperature plasma, away from the center. This spreads the plasma all around the Tokamak reactor. That also causes the plasma to touch the reactor’s structure. When the plasma, which is at temperatures of billions of degrees, destroys the reactor. 

The solution could be. The system pushes back when fusion starts. This means. The energy level is at the outermost layer of the plasma. It should be higher than the center of the plasma ring. The idea is this. The energy level in the outermost layer of the plasma ring is higher than in its inner layers. 

That outside energy pushes the deuterium and tritium together, forming helium. Lithium deuteride, lithium hydride: normal hydrogen is replaced. Using deuterium is a good source for deuterium and tritium. But that system requires a neutron source. 

In thermonuclear weapons. The small nuclear bomb. Creates the needed energy and neutrons to start fusion. Maybe. Fusion reactors. They could use a neutron source and laser-accelerated neutrons to create conditions that can start fusion in lithium deuteride. 

The outer layer’s higher energy level helps to keep that plasma in that form. If. The energy level in the middle of the plasma ring rises higher than the outermost layer. That energy breaks the plasma ring. And fusion is impossible. The key element is to keep that plasma in one form.

If that is possible. Researchers. Are one step closer to a fusion power plant. The technical problems with this type of reactor are huge. But if that reactor can transport energy into the network. This can be the next step. To benefit renewable energy. The main problem with a hydrogen economy is how to produce hydrogen.

Hydrogen is a promising energy source. If it is produced using clean energy. Things. Like aircraft carriers. They could produce hydrogen for their air wing as fuel. Fusion reactors can offer a clean way to produce hydrogen.
