A article on newscientist that caught my eye...
Sunstones huh, souds interesting.
So I am sure someone has some info on the stories mentioned in the article,
about how the vikings used sunstones to navigate.
Well if we could rediscover this technology I think it would be useful.
Say if we had a magnetic disturbance in our atmosphere, causing compasses to direct falsly,
a sunstone would be quite useful.
