comment How small can you be and still hear?
Also, you can hear tones even if their RMS value is lower than the RMS value of white noise.

So as diaphragm size increases, signal-to-noise ratio improves?

revised Would an octahedral magnet work as a magnetic bottle?
clarify the focus of the question is only on confining particles, not fusion or anything else

comment Would an octahedral magnet work as a magnetic bottle?
Thanks for the answer. Note that Stack Exchange is not a forum; it's for concise focused questions, so I phrased this question to ask only whether this shape would confine charged particles (whether for fusion power or for studying plasma or whatever other purpose). Anything else about fusion or power generation is off-topic and should be addressed by different questions.

comment Would an octahedral magnet work as a magnetic bottle?
@user23660: in other words, this is trying to combine multiple magnetic bottles with alternating magnetic polarities to get a more spherical symmetry, while polywell has all the magnets monopole-like facing inwards, like trying to combine multiple biconic cusps to get a more spherical symmetry.

comment Would an octahedral magnet work as a magnetic bottle?
@user23660: Yes, this is based on polywell and the problems they have with particles hitting the magnets.

comment What is non-thermal plasma?
Doesn't "non-thermal" imply that the temperature of the plasma is meaningless?

comment Does magnetic geometry determine the scaling of a Polywell fusor?
"the polywell mainly aims to confine the electrons magnetically" I thought it confined them by electrostatically charging the spherical grid, and the magnets in the grid just coaxed the electrons to go through the holes in the electrode instead of hitting it. Am I misunderstanding?

comment Would a fast inter-stellar spaceship benefit from an aerodynamic shape?
so extremely fast spaceships should be needle-shaped to minimize cross section?

comment Would a super-hot object launch itself into the air?
I guess this indestructible box is mostly air, so it's going to have a lot of buoyancy

comment What would ACTUALLY happen to a person jettisoned into space?
Unless you're near a hot object, you will eventually freeze, but it takes hours for all your body heat to radiate away.
