Google Street View has announce the addition of new images within the exclusion zone in Japan. You can easily view the official Google site here. The images are truly revealing and show the insane impact the Earthquake and Tsunami had on the area.
I found some interesting technology while looking at the new images, it looks like a solar powered sensor system of some kind. I suspect it's a Geiger Counter with a nice display on it with the value it reading, would love to hear from anyone with more insight into what it could be?
