hard to come by and that are essentially effectively irreplaceable are the high voltage transformers that you saw in the first step down that is really critical to the backbone of the grid. >> a couple questions. number one, when you talk about some of the bigger parts of it, is it true that some of it is made in china and other countries so that were they to be damaged and our power went out totally in this country that we would have a hard time replacing some of the main components? >> yeah. as i understand it, these transformers, which, as i say, are the backbone, really, of the grid, the high energy transformers of which we've got about 2,000, essentially no spares to speak of. they're custom built for where they go into the grid, and it takes about a year to have them custom built, hand built, no less, in places principally like germany, south korea and india perhaps. where the thing really breaks down is, if it takes a year to get one, and then once you've
