I suppose one has to assume that the backup diesel pumps are no longer functioning, destroyed by the tsunami. Then we heard that they had tried to use battery power, but that didn't work either.
I don't really understand. I thought the US military had delivered new diesel pumps to the site, what happened to them?
Why are they dragging an electric cable power source in? What will they connect it to, what pumps? If the primary pumps were destroyed in the earthquake and the tsunami, and the secondary diesel pumps were also destroyed, what's the electricity for, for what pumps? I find it confusing and worrying.
ITS1789 on a thread at the Guardian has all the same questions I do on the Fukushima nuclear crisis.
