Deuterium fusion Starships III

Friedwardt Winterberg’s fusion pulse driven space vehicles initiate fusion by injecting a rapid jolt of energy into the fusion target causing an implosion to high density fast enough that the fuel fuses before being blown apart. A mere 10 MJ is enough for the D-T triggered D-D pulse units to implode, but it has to be pumped into the target in a nanosecond – a power of 10 quadrillion watts (10 petawatts, 1016 W.) In his original papers Winterberg outlines two multi-use triggering systems – a super-Marx Generator, which is a huge linear bank of Marx generators, and a gigavolt charge build up on a space-ship in the high vacuum of space.

But what if there’s a different way? A new capacitor design theoretically has more than enough power (~1019 W/kg estimated) and enough energy storage (1 MJ/kg) to allow a very light weight triggering system for fusion…

Digital Quantum Batteries
…a research paper describing the concept and preliminary designs. The system uses billions of nano-scale vacuum tubes (for want of an analogy) which can be used as information storage (thus ‘Digital’) and as power storage, via a tricky quantum effect that enhances the electric field strength far more than expected from classical electronic theory.

If this research pays off, then this is potentially a game-changer for pulsed fusion.
