1990s sectoral corrosion cost breakdown

There are studies and the corrosion people still do them. This one is probably about the 1990s, and they actually broke it down by different sectors. The biggest sector for corrosion — and this is replacement of things — is drinking water and sewer systems, thirty-six billion a year. Motor vehicles is twenty-three billion a year because cars rust out. Defense, that you should have some interest in, is about twenty billion a year. Twenty billion a year is a lot more than the budget of most of the militaries of anybody in the world except us, because we're spending about two-thirds of all the world's military budget. Of course China gets a little more for their dollars.
