There's this very cool blog I found on the nets.

 

 

We Need More Antimatter: Here’s How To Get It

 

Antimatter is the ultimate fuel for high-speed space propulsion. While we can in principle make do with nuclear rockets for interstellar colonization, antimatter is in a different league entirely. They would enable interstellar travel at speeds of up to 30 to 70% of light speed, three to eight times higher than any form of nuclear propulsion, even the Orion ship that I love talking about so much.

 

The problem, of course, is producing antimatter in sufficient quantities. We need tons—literal tons—of antimatter to power a starship of any appreciable size. That is somewhat more than current antimatter stockpiles, which are barely capable of powering a lightbulb. Although antimatter production is increasing exponentially, we need to do better. Much better.

 

This blog will examine some of the weird and wonderful ways we could get more antimatter. Because antimatter is awesome. And so are rockets. Therefore, antimatter+rockets must be even more awesome, right? Right? Okay...just so as not to scare everyone off with my mad ravings about strange and futuristic things, I'll begin with methods that are mostly just extensions on existing technology, not some absolute craziness.

A very enjoyable read, you shameless self promoter.

Yes, enjoyable, but it's not quite accurate, as there is a fuel even more potent than antimatter: black holes. Kugelblitzes, to be precise. I recall someone doing the math, and they said that the difference in power between an antimatter power source and a black hole power source is somewhere on the order of eight orders of magnitude. Antimatter fuel is used relatively quickly in one go and produces terawatts of power per second. A black hole can last for years and produces anywhere from exawatts to yottawatts of power per second. Not to mention that, if you managed to somehow play with its gravitational field, you might even break physics and produce a warp bubble that can help you get somewhere even faster, perhaps even slightly faster than light. You wouldn't go faster than light locally, but you'd zip along at ungodly speeds outside of your pocket of warped spacetime. 

 

Currently in the process of fact checking this, so give me a while to find the posts.

 

TLDR for the amount of energy you need to create enough usable antimatter, you could also create a black hole.

Well not really more potent. Just more energy dense per volume NOT MASS depending on the size of the blackhole. It is equviliant to anti-matter if we go by mass.

What is true, just, and beautiful is not determined by popular vote. The masses everywhere are ignorant, short-sighted, motivated by envy, and easy to fool. Democratic politicians must appeal to these masses in order to be elected. Whoever is the best demagogue will win. Almost by necessity, then, democracy will lead to the perversion of truth, justice and beauty. -Hans Hermann Hoppe
