Recent questions
How does Helion Energy's Trenta nuclear fusion generator work?
The Trenta nuclear fusion generator by Helion Energy operates by forming two mirrored rings of plasma on either end of a reactor, colliding them to fuse and convert kinetic energy into thermal energy. This unique approach allows fusion reactions to occur at temperatures of tens of millions of degrees, overcoming electromagnetic repulsion to fuse atoms and release a significant amount of energy. The fusion process involves merging field reverse configurations to compress fusion plasma and accelerate it to over a million miles per hour, creating new particles and generating energy.
What is the fuel mixture used in Helion Energy's fusion reactions?
Helion Energy's fusion reactions utilize a fuel mixture of deuterium and helium-3. Deuterium is a common element, while helium-3 is rare but essential for efficient fusion reactions. When these two elements fuse inside the reactor, they create new particles and release energy. The mass difference in the final products, particularly helium-3, carries useful energy that can be captured to generate electricity.
How does Helion Energy capture energy from fusion reactions?
Helion Energy captures energy from fusion reactions by focusing on charged particles like protons and tritium. Neutrons, which carry most of the energy in fusion reactions, cannot generate electricity. Protons and tritium isotopes created in fusion reactions are captured for energy generation before being exhausted through a turbo molecular pump. Tritium decays into helium-3 over a period of 12.3 years, ensuring a sustainable pathway for generating energy from deuterium and helium-3 fusion.
What are the advantages of generating fuel on-site for fusion reactions?
Generating fuel on-site for fusion reactions offers several advantages. It provides the option of a dedicated fusion facility for fuel production, separating deuterium fusion from electricity generation to prolong generator life due to neutron damage. Designing a cheaper, robust reactor solely for fuel production could be economically beneficial in the long run. Additionally, moving away from deuterium and tritium reactions to deuterium and helium-3 reactions offers benefits, although the latter requires higher temperatures for fusion to occur.
What are Helion Energy's future plans for fusion technology?
Helion Energy's future plans for fusion technology involve the development of Polaris, a seventh-generation system that aims to demonstrate electricity production by 2024. Polaris will build on the advancements made in fusion technology, including precise control of electricity bursts for fusion reactions. The new system will be 25% larger than previous models to accommodate new discoveries and advancements in fusion technology.
