rafknúnum

Could you clarify what "rafknúnum" refers to? It appears to be Icelandic and could mean "electric-powered" as a general term, or it might be the name of a place, organization, project, or other specific subject. Do you want a linguistic overview of the term, or a concise wiki-style article about a particular topic named "rafknúnum" (if you have a specific context or source, please share it)? Once you specify, I can draft a neutral, under-300-word article.
