I really haven't touched on the specifics of the nuclear situation occurring in Japan. This has been intentional on my part as analysis of events by "experts" in the field have been all over the board and I'm in no position to really delve into any sort of deep criticisms of what is being said.
That explanation out of the way, I just came across this video on reddit and had to share it. It is a heavily simplified and animated explanation of what is occurring at Fukushima Daiichi.
Now, deconstructing a current event like a potential reactor meltdown into a pretty silly animation is something I consider to be pretty distinctly Japanese, and I don't know if it would be all that warmly received in the US. But I do think that this method of presentation can be much better at explaining what is going on, and having it understood, than a talking-head scientist might be.
