1) What do these folks do for work that they can live up in the Arctic in this fashion?
2) How do they keep the dome's light from being completely obliterated. In the second to the last picture from the bottom you can see the dome almost completely covered in snow, which would make it very dark inside. Unlike in majority of photos where there is no snow covering the glass.
The name of the island in the article is a link to its Wikipedia page, from which another link takes you to the page for Nordland, the county it belongs to. https://en.wikipedia.org/wiki/Nordland#Economy
> How do they keep the dome's light from being completely obliterated.
As another poster noted, the dome is not very well isolated. As a wild guess, this might mean that thin layers of snow could melt off if it's not too cold outside.
Also, during the three winter months when it doesn't get light outside at all, you might as well live under a layer of snow. Its reflection of the house's lights should give an overall brighter feeling than if the light just goes off into the arctic night.
Is this as big as a tourist draw as the fjords around Bergen? It looks equally as impressive.
Has a bit more infrastructure and job opportunities, if that's something that is relevant to you - and plenty of "alpine" mountains in the surrounding area.
That said, the Lofoten area is famous for its spectacular beauty - many graphical artists and painters have lived moved there over the years because of the unique landscape and light.
Further north than Tromsø, things get a bit flat as you move up towards Finnmark - and more remote. And then there's of course Svalbard, if you want to live in an area that's more like northern parts of Alaska...

I'm guessing people clean these with a telescoping pole. But I could see that being a back-breaking exercise. But maybe that's a small place to live in such harmony with your surroundings.
