Not a new article, but I found this interesting. "Artificial" sunlight in places which would not normally see the sun throughout the winter.

The villages of Rjukan, Norway, and Viganella, Italy, are both situated in deep valleys where mountains block the sun's rays for up to six months every year. To illuminate those darker winter months, the two towns have built gigantic mirrors that track the sun and reflect daylight downwards. Viganella completed its huge computer-controlled mirror in 2006, and Rjukan followed suit just this month, mounting a mirror that will reflect a 600 square meter (6,500 square foot) beam of sunshine into the town square below.

What benefit does it have besides providing more daylight? Is it the psychological effect of bright sunshine? There is not going to be much heat value in reflected light

LOL - Exactly.
They have only their forefathers to blame for building a city in the wrong location.

I bet this cost a fortune as well.
They should have invested in those shakey torches that charge when you jerk them off.

Give every villager a torch and tell them to stfu :p
 
I wonder what the psychological impact of this will be. The sun rise in the South-West (I'm guessing), and stays there the whole day...
 
Reminds me of Lancre :

There isn’t much of the kingdom of Lancre where you could drop a football and not have it roll away from you. Most
of it is moor land and steeply forested hillside, giving way to sharp and ragged mountains where even trolls wouldn’t
go and valleys so deep that they have to pipe the sunlight in.
