Well got a longer note from the BIL last night. I asked him how the solar and wind units made it through the quake and tsunami.
The roof mounted solars did OK as long as the building handled the damage. The ones mounted on poles mostly went down due to the motion. The wind units in the southern areas seem to be OK but the ones up north are all gone, most of them just fell over during the quake I guess.
He also told me that Japan uses a weird power grid. The eastern half uses a 60 hz grid frequency while the western side uses 50 hz power. That is one of the items causing problems now. They cannot just shunt power from one side to the other.
He said that so far Tokyo has had some blackouts but that they have been short duration and his place near Chiba hasn't been out for more than 10 minutes.
