You would also be getting the same benefit from the electron-positron annihilation gammas, but those will be negligible. Luke |

Probably not possible, but not proven to be so just yet. Right?

If you need FTL anyway, why not use the same FTL mechanism to also get you other fun stuff? Orientable wormholes give you rapid transit to other star systems, non-orientable wormholes give you bulk antimatter. Wormholes have not been shown to be possible in real life, but they are a valid solution to Einstein's equation in general relativity so their existence cannot be ruled out a priori. I am not going to say they are probable or improbable - science doesn't work that way - but they are fun for fictional purposes. For my own setting I use wormholes extensively, both for transportation and energy http://panoptesv.com/RPGs/Settings/V...s/TheVerge.php Another non-physics-denies method of getting energy is to use magnetic monopoles (which are predicted by many theories but not yet observed) to catalyze baryon decay into light leptons and energetic radiation. "Matter to energy", as it were, using more popular but incorrect terminology. Luke |

Re: [Spaceships] Anti-Lithium for Drives – Does this work?
Just a vague speculation, but anti-lithium is a solid at room temperature, while anti-hydrogen and anti-helium are gases at all but very low temperatures. That might make it easier to handle and store.
Though if you don't have a really really good way to store antimatter you probably shouldn't be messing with it at all...

Re: [Spaceships] Anti-Lithium for Drives – Does this work?
But storing matter hydrogen is exceptionally difficult for more than short term, especially if you care about individual atoms escaping rather than tens of percents.
Antimatter hydrogen must be similarly difficult, so on a purely storage issue, nearly any other type of antimatter would be easier and safer. But making it in such a way as to make any economical sense seems nigh impossible. Maybe very niche small super speedy military vehicles of a very wealthy government.

Assuming that you can make non-orientable wormholes with throat diameters of around 100 pm you could make antilithium as long as the wormhole is open, which I think just means big initial costs in generating the required negative energy densities (much lower than the densities needed for large traversable wormholes at this scale). Once you have the wormhole all you need to do is keep it open and shoot lithium ions through. |
