description: "A dynamo current drive (hence “Dynomak”) is a proposed model for predicting the magnetic field based on the injection of outside magnetic fields. This could have huge implications for fusion power."

# The New Dynomak Fusion Reactor Design Could Make Fusion Power Cheaper Than Coal

![Default Futurism featured image](<https://futurism.com/wp-content/uploads/2025/10/Futurism-Filler-Image.jpg>)

- A Dynomak facility could be built for about a tenth the cost of competing fusion reactor designs and produce up to five times as much power
- Essentially, the Dynomak is a precisely controlled spheromak reactor that uses imposed dynamo current drive to control the magnetic field it creates
- Given the incredible cost benefits, the project would be a huge breakthrough.
