Episode notes
Fusion's Powerful Efficiency
- Fusion is a process of smashing together light atomic nuclei to form heavier elements and release enormous energy.
- It is millions of times more efficient than fossil fuels despite converting only about 0.1% of the fuel's mass into energy.
Fusion's Historical Challenge
- Achieving break-even energy output in fusion has been a historic challenge with massive machines and budgets involved.
- Fusion is often considered perpetually "20 years away" due to scaling and cost challenges.
Helion's Fusion Innovation
- Helion uses a unique linear, compact, pulse-driven fusion reactor, different from traditional tokamak designs.
- It fuses deuterium and helium-3, which produces mostly charged particles that are easier for energy capture and are less radioactive.
