The IPCC report strongly encouraged not only trying to get our carbon dioxide emissions down to fight climate change, but to go into negative emissions so as to draw the carbon dioxide out of the air (since it's too high as it is). Wouldn't that help to fight ocean acidification too? Because...

What I mean is that I was reading that for an idealized box, that the waves have nodes at the edges of the box, but that when dielectrics are used, it can make the edge of the box "fuzzy" in regards to the wavelengths that can fit inside. I'm just trying to get a better handle on the how and why.

I suspect that it doesn't, since a dielectric shouldn't affect the null field value for standing waves at the boundaries. I just wanted to confirm if my thinking was right.

How do dielectrics affect the number of modes for standing electromagnetic waves in a box?

I don't have any info for voltages or currents yet, since it's still a theoretical exercise (but I'm trying to get to the point where I can determine voltages and currents). As such, I'm determining what the generator would look like, particularly since I'm also trying to determine the exact...

For more details, I was considering a very small electric generator with also a very small driving force. I know that obviously an electric current would be induced from the rotation, which in turn would generate a magnetic field that would oppose the motion. When doing calculations involving...

For a microscale electric generator (where the driving force is a fraction of a Newton), can losses from eddy currents be significant enough to noticeably alter the rotational velocity of the rotor? Because my understanding is that the rotation is basically taken as a constant when examining the...

I had started by looking at the authors of some books about it, but wasn't able to readily narrow it down. Part of the reason that I asked was to see if people had an idea off the top of their head for various places.

Yeah, sorry about not clarifying that, but I'm asking within the context of pursing it for graduate study.

I'm interested in the theoretical aspects, but also being mindful of how easy it is to test those ideas.

What would be a good school/s for studying the Casimir Effect at?

Ok, cool. Because I thought that it only supporting conduction along the axis sounded a little strange.

Can carbon nanotubes support electron propagation perpendicular to the axis? That is, can there be circular current flow on the tube's perimeter, not just the linear flow parallel to the axis? Because I reading that it's generally considered a 1-dimensional conductor.

Good point; I hadn't considered about the tube possibly being dragged along, or the compression heating.

If a magnet was going fast enough as it approached/entered a copper tube, could the current induced in the tube via Lenz's Law be high enough to melt or even vaporize the tube?
