Helicity Space CEO Dr. Stephane Lintner, Chairman Jeff Neuman, COO Marta Calvo, and CTO Dr. Set You, discuss the magneto-inertial fusion Helicity Drive with Balerion Advisor Doug McAdams.
Helicity scientist Seth Pree is on the right running the recording. This webinar was preceded by a tour of the Helicity lab spaces which include a functioning non-nuclear prototype. Following the webinar, we toured NASA Jet Propulsion Laboratory at the California Institute of Technology which is slated to build the upcoming nuclear prototype with Helicity.
00:00 – 01:30 Welcome & introductions
Doug McAdams opens the webinar from Pasadena and introduces the Helicity Space leadership team: CEO Dr. Stéphane Lintner, Chairman Jeff Neuman, COO Marta Calvo, and later CTO Dr. Set Yu.
01:30 – 03:00 Founders’ backgrounds & company origins
Stéphane discusses his background spanning Caltech science, JPL projects, and Wall Street banking, explaining how Helicity combines technical rigor with disciplined company-building.
03:00 – 04:30 Why propulsion is the real space bottleneck
Doug frames the problem: chemical rockets get you to orbit, but deep-space missions are constrained by the rocket equation, thrust-efficiency tradeoffs, and fuel mass.
04:30 – 06:00 Why fusion propulsion is inevitable
Helicity explains why fusion has always been the theoretical solution for deep-space travel, referencing decades of physics and popular science visions (Star Trek, The Expanse).
06:00 – 07:45 Introducing Helicity’s fusion breakthrough
The team introduces Helicity’s novel fusion propulsion concept and credits the foundational scientific work of Dr. Set Yu, whose plasma physics research underpins the system.
07:45 – 09:30 Dr. Set Yu’s background & scientific journey
Dr. Yu outlines his path through Imperial College, Caltech, the University of Tokyo, and the University of Washington, culminating in a DOE Early Career Award and the invention of a novel plasma gun.
09:30 – 11:30 Why fusion in space is easier than fusion on Earth
Key insight: space propulsion does not require continuous, wall-plug-efficient power generation—only momentum—making fusion viable earlier in space than on Earth.
11:30 – 12:45 Pulse fusion vs steady-state fusion
Explanation of why intermittent fusion pulses are useless for terrestrial power but extremely valuable for propulsion, orbital maneuvering, and spacecraft acceleration.
12:45 – 15:15 Magneto-Inertial Fusion explained
Dr. Yu explains Helicity’s approach: an intermediate “Goldilocks” regime between magnetic confinement (tokamaks) and inertial confinement (lasers), balancing density, confinement time, and system size.
15:15 – 16:45 What makes Helicity’s approach unique
Two differentiators:
* Magnetic reconnection heating to preheat plasma efficiently
* Modular, multi-jet scalability—like adding cylinders to an engine—avoiding material limits of single-source systems
16:45 – 18:30 Near-Earth and cislunar applications
Helicity’s drive enables continuous acceleration for heavy cargo transport, orbital logistics, refueling infrastructure, and national security applications.
18:30 – 20:00 Lunar logistics without launch windows
Fusion propulsion allows flexible, on-demand Earth-Moon transport, avoiding orbital timing constraints and drastically reducing fuel requirements.
20:00 – 21:30 Mars missions: speed, safety, and radiation
Comparison to Starship’s ~9-month Mars transit: Helicity enables ~2-month trips with abort capability, dramatically reducing radiation exposure and mission risk.
21:30 – 22:45 Science missions & asteroid exploration
Fusion propulsion shortens mission timelines (e.g., Psyche-like missions from years to months), lowering costs, accelerating science, and enabling sample return at scale.
22:45 – 24:30 Commercial traction & investor interest
Helicity discusses backing from venture investors, collaboration with Caltech and JPL, and strong interest driven by real experimental results—not theory alone.
24:30 – 26:00 Development roadmap & funding strategy
A staged, capital-efficient plan:
* Proof-of-concept achieved (~1M° plasma)
* Scale to 10M° and fusion conditions
* Modular expansion to net gain
* First fusion drive demonstrated in space within ~9 years
26:00 Closing remarks & invitation
The team emphasizes disciplined de-risking, government collaboration (NASA, DOE, DoD), and invites qualified partners to engage further, while noting appropriate security sensitivities.
