Scientists are exploring fusion power as an emerging clean, renewable energy technology to achieve net-zero emissions. There are two main types of devices for this research: stellarators and tokamaks.
In simple terms, the difference between a tokamak and a stellarator comes down to how they shape and control magnetic fields to handle hot plasma during nuclear fusion:
- A stellarator has a more complex, twisted, and three-dimensional shape
- It uses carefully arranged magnetic coils to create a 3D magnetic field that confines the plasma
- Unlike a tokamak, a stellarator doesn’t need a net plasma current. It achieves stability through the magnetic field’s inherent design
3D modeling of the famous Wendelstein 7-X (W7-X) fusion reactor in SOLIDWORKS. It’s among the most promising research concepts to achieve clean energy and combat climate change. The W7-X is the largest experimental stellarator built at the Max Planck Institute for Plasma Physics in Germany. It took around 1.1 million hours (19 hours) to build this massive plasma device in reality, spanning 16 meters across.
