Understanding the concept of cross section

The cross section is a tiny area, measured in barns ($10^{-28} \mathrm{m^2}$), which relates to the probability of a reaction. But I have trouble interpreting that number. For example how can I ...

Polarizing virtual photons to make fusion easier?

So, this is probably incredibly foolish, outlandish, etc but I figure I'd post it anyways. Basically I was thinking about how the Deuterium nuclei repel each other and how they do this by exchanging ...

Does the plasma move in the tokamak?

I was reading about tokamaks, for usage in fusion, and it seems that the positive ions circle in one way in the toakmak, while the negative circles in another. That would make a lot of sense, as it ...

Can we use a warp bubble for nuclear fusion?

I understand NASA is now experimenting with a tweaked Alcubierre drive. Apperantly some physicists predict crazy heat (hotter than the sun) inside the warp bubble caused by Hawking radiation (recent ...
