[edit] More light than equatorial regions?

The article says "In fact, polar regions typically get more light throughout the year than regions located closer to the equator."

But what does "more light" mean? Higher annual total insolation in watts? Or (as I suspect) more hours of non-darkness? Either way it should be clarified, and hopefully quantified. Chondrite 16:17, 15 September 2006 (UTC)

[edit] Mountain Eclipses

I remember something about villages south of the arctic circle, but experiencing polar nights due to being north of mountains, which put the whole village in shadow. I suppose it's probably more of a twilight than a night, but it might be worth mentionning. —The preceding unsigned comment was added by M0ffx (talk • contribs).

That's an interesting detail, and it would bear mentioning, but it would really be best if we had some kind of citation for it. Do you remember where you learned this, and (ideally) can you dig up a reference we could cite? — coelacan talk — 03:45, 2 December 2006 (UTC)

I _think_ the source may have been New Scientist. There was an idea (implemented I think) to place large mirrors at locations suitable to light parts of the village center. Unfortunately I can't remember which issue of New Scientist. M0ffx 21:39, 7 January 2007 (UTC)
