# In 1000 years, could a magnetic bottle-like plasma dome system protect a small city? [closed]

I've looked at the magnetic bottle (hydrogen plasma/fusion) idea as a potential basis for extrapolating what technology might be capable of doing with plasma fields 1000 years into the future...which is when my novel is set...but I'm worried about the heat it might give off, as well as the large electromagnetic field needed, which could cause the people inside or within a certain radius of the dome to be killed. Additionally, a magnetic bottle would be disrupted by the interference of the soil/ground, if it were just one magnetic bottle per dome. Maybe a series of magnetic bottle-like plasma fields - vertically or horizontally arranged - in a dome-like shape could work?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

• Plasma? It would be like living inside the sun itself, and your heatsinks are trying to absorb/divert the heat of the sun. Science-based this just seems weird. We would have to first solve what prevents the plasma from causing the air around it to excite instantly into something close to a nuclear explosion. – Trevor D Dec 17 '18 at 19:51
• Welcome to worldbuilding. Please take the tour and visit the help center to understand our standards, then rework your question. As it is now it is too broad (we prefer 1 well defined question per post), unclear (what do you mean with "adding an electromagnetic charge"?) and also opinion based (in 1000 years we don't know what the tech level will be or if we will still be there). – L.Dutch Dec 17 '18 at 20:20
• To figure out what will be possible in a thousand years, see what people from thousand years ago predicted properly about today. Or people in the 30s or 50s, really. Then you will see the impossibility of such predictions. – Mołot Dec 17 '18 at 22:33

• Please update your question to state exactly what kind of setup you want, what it is for, and what your concerns are. As of now i cannot figure out where the plasma is supposed to be, why it would be there, for what reason, and what magnetic bottles have to fo with it. – bukwyrm Dec 18 '18 at 8:20
