Gemini says a firecracker releases 150 J, so yeah not a lot.
For a tiny number, that is still insanely high...
CERN can make/store the antiprotons, but not measure them as cleanly as they want because the facility itself introduces tiny magnetic fluctuations. So this is really a story about moving the sample to a quieter lab, not moving toward sci-fi antimatter batteries... for now
Or something.
Was kind of disappointed to see it was transported via 18-wheeler.
Of course, it's compact because it only has to last so long. CERN's press release discusses needing a generator and a cryocooler in the truck for longer trips: https://home.cern/news/press-release/experiments/base-experi...
This older article about the test they did with ordinary protons, indicates the outer frame measures "2.00 meters in length, 0.87 meters in width, and 1.85 meters in height" and comes in under 1000kg https://ep-news.web.cern.ch/content/cerns-base-step-leap-for...
Either nothing would happen, or like molten salt in water, the joule currents would be instant and drive it all to go boom in a big way. I wonder which.
It would immediately explode.
Being able to transport it seems like an important piece of that puzzle.
Production and storage would need to be scaled by many orders of magnitude, but that's merely an engineering problem...right?
Not necessarily because I want to use it, but because I have a vague idea of what it's capable of, and what that would mean in the hands of certain groups capable of producing it.
If you're ok with the looming threat of total annihilation.
I suppose at least it will kill you faster than your neurons can communicate so you wouldn't even notice.
A slightly less insane fuel source is a micro black hole. Drag a tiny black hole behind your ship and drip-feed it any kind of mass you come across. You still get >90% mass-energy efficiency which is far beyond anything else we know of.
Besides, one of the big problems with antimatter is that it's a battery, not a fuel source. We must first collect the unimaginable amount of energy and then process it into antimatter one particle at a time. If you build a ton of factories around a star you can get meaningful production. But a black hole drive can suck up interstellar gas or any asteroids you come across. Matter is easy to get. Don't ask where the micro black hole comes from.
The fact that we don't see these glowing boundaries in space is evidence that there are not antimatter regions and that the visible universe is almost entirely composed of matter.
More accurately: we aren't sure if antineutrinos are the same or different from neutrinos!
