The Stellarator Reborn
# Breakthrough fusion technology designed for operation and scale
We’ve radically evolved the stellarator, enabling systems to be simpler and more practical than previously thought possible. With this groundbreaking technology, Thea Energy is changing the trajectory of fusion energy.
## thea energy Fusion technology
### Stable, steady-state magnetic confinement fusion
The stellarator is a highly efficient power plant architecture
###### Steady-state
Inherently stable magnetic confinement with no risk of disruptions.
###### Full 3-dimensional field control
Dynamic correction of system operating conditions.
###### Highly efficient
No requirement for current drive systems, with low recirculating power.
###### Simplified system and magnet architecture
We’ve eliminated the longstanding Achilles’ heel of the stellarator: system complexity.
##### Steady-state
##### Highly efficient
##### Full 3-dimensional field control
##### Simplified system and magnet architecture
## The stellarator reborn
Prior iterations of the stellarator were much more complex than other fusion systems such as the tokamak. This was a limiting factor–until now.
Our proprietary stellarator technology eliminates the intricate 3D magnet coils required in all other proposed stellarator architectures. These modular coils are extremely difficult and expensive to manufacture, assemble, and maintain.
By transferring the complexity of 3D magnetic fields to modern electronic control systems, we leverage the significant developments in computing and control systems. The result is a radically simplifying (and cost-reducing) new paradigm.
Our stellarator architecture and magnet systems can be built in simpler, less expensive ways, while solving long-standing barriers to fusion energy.
## Introducing Eos
Our first system, Eos, is a neutron source stellarator capable of commercial operation for the production of various isotopes including tritium. Eos is the only first-generation fusion system prototypical of a power plant. Our development roadmap is not contingent on further scientific breakthroughs. No miracles required.
#### Large-scale planar coil stellarator
Our breakthrough stellarator architecture uses computer-controlled arrays of HTS planar coils.
#### Capable of near-term commercial operation
D-D fusion for the production of tritium and other isotopes including medical radioisotopes.
#### Dynamic field control​
We can optimize machine parameters and dynamically change operating points in real-time.
#### Simplified commercial system maintenance and operation
Our planar coil arrays allow for sector maintenance, minimizing downtime.
#### Dynamic field control
# Thea Energy fusion power
Our proprietary stellarator architecture enables safe and reliable baseload fusion energy generation at a lower capital cost. We’re accelerating commercialization of fusion energy to curtail climate change and provide for the long-term energy needs of humanity.
##### On-the-grid power generation
Our planar coil stellarator technology enables a more practical power plant design, with on-the-grid operation in the 2030s.
##### Rapid commercialization and scaling of fusion power plants across the world
Thea Energy’s modular system architecture enables simpler manufacturing and construction of fusion power plants, allowing for the rapid deployment of carbon-free energy at scale.

## Next up: Eos, a large-scale planar coil stellarator
 Learn why the planar coil stellarator architecture gives us a more practical and efficient path to commercialize fusion energy.
Why It Matters
##### Expansion into HTS Magnet Manufacturing, Scaling & Iteration
Following the close of our Series A, we rapidly began prototyping HTS magnets.
Our proprietary architecture and IP allow for all magnet systems to be constructed using more conventional manufacturing methods, a radical simplification of stellarator magnet design and a critical advancement allowing for the deployment of stellarator fusion power at scale.
We’re able to iterate our core fusion tech at a quicker pace.
By utilizing an array of smaller and simpler planar magnets, we have been able to advance our tech from generation to generation on a time scale of months, not years (like prior modular stellarator magnets) and for orders of magnitude less capital.
##### HTS Planar Magnet Testing
Our current testing campaigns operate these superconducting magnet coils at scale and high field, validating our ability to produce the complex magnetic fields required for stellarator systems.
##### HTS Magnet Array Testing
Next we will operate a 3×3 array of high temperature superconducting magnets.
This system will validate our core planar coil stellarator tech and demonstrate our ability to create and dynamically control a stellarator plasma’s precise and complex magnetic field.
Why this is a Big Deal
# Reinventing the world’s energy supply with programmable magnets
Our vision is to manufacture compact magnets and other modular system components at scale, load them into containers, and ship them around the world to any customer interested in safe, around-the-clock, carbon-free power plants.
###### Magnet Pixels for High-Definition Stellarator Plasmas
We’ve shifted the complexity of the stellarator from hardware to software. For the first time ever, we can precisely dial-in arrays of magnets via an electronic control system, creating a stellarator with an order of magnitude better confinement than prior modular coil stellarator devices.
###### AI/ML for Dynamic Field Control
Via our control system, we take advantage of the recent revolutionary advancements in AI, ML, computation, and control systems to develop a device that can continually re-optimize itself.
###### Real-World Operation
Our architecture and ability to individually control each magnet allows us to correct for hardware variability including defects and off-spec manufacturing, mounting inconsistencies, real-world conditions, and long-term wear and tear.
