I got two! It looked like another CQCB opportunity but this time they closed access to the ticket very fast 😜

Haha, that would be super cool! Like, Nobel-price-wrothy innovation if we learned to do so much :)
But yes, theoretically, that would be a lot of energy, awesome for space ships!

You can read about BASE, one of the experiments also on CERN news home.cern/news/news/ex...
and I'm sure they will also publish updates when it's done with antiprotons

The biggest danger here is just batteries and electricity (comparable to electric car) and liquid helium that is at -269C but that simply evaporates when it heats up🎈🎈🎈
So would I want it in my back yard? Yes, please! 😂

No danger at all, the energy from annihilation is currently so small that we need very sensitive detectors to even see it. Experiments planned next year talk about transporting 10^9antiprotons, a gram would be 10^23 so we are very far from any dangers :)

Exactly! It's less than Joule of released energy, mostly in form of particles flying out undetected and decaying fast... A radiation detector like Geiger-Muller counter would maybe beep once, that's it 🙃
And to do 1g as in movies, that would take us millions of years at current rates
