- The argument is built upon the following causal and conceptual chain:
- David Kirtley argues that nuclear fusion represents a transformative energy solution with the potential to provide virtually unlimited, clean, safe electricity, radically changing the trajec
- The abundance of deuterium in Earth’s water and cosmic isotopes means fusion fuel is effectively limitless for millions to billions of years, making energy scarcity obsolete.
- Replicating this on Earth has been historically difficult due to the need to achieve and sustain extremely high temperatures and confinement without relying on the sun’s gravitational confin
- Fusion powers the stars by fusing lightweight isotopes (hydrogen, deuterium) at ~100 million degrees Celsius, releasing energy via mass-energy conversion (E=mc²).
- Helion Energy’s pulsed magneto-inertial fusion uses rapid magnetic field reversals to self-organize plasma into a confined state, enabling higher efficiency energy extraction directly from c
