Interesting yes, but regardless of the scientific viability of Helion's approach (that I have no means to discuss), at least they are aiming at addressing the core problem of fusion energy as an investment strategy: turning an non-existent into an existent technology. What bewilders me here are people discussing the business model and implementation details of these ships' reactors for the endeavor to become profitable. These kind of discussions would only be appropriate in the Worldbuilding StackExchange.
