Seems as though Corning has always been an up and down kind of
business.

After the telecom fiasco, Corning downsized, got rid of some weak
product
lines and focused back on their core business. The stock has slowly
recovered from a low of about 2 bucks a share up to the mid to high
20's.

Many years ago Corning developed the ceramic "rice" used in catalytic
converters for gas powered cars. I was involved in the design,
building,
test and installation of several sputter deposition systems that coated
the
"rice" with the catalytic material.

In addition to LCD glass (their primary business) and fiberoptics,
Corning
is the primary supplier of the catalytic material now required in the
newer
diesel powered trucks. I think I recall reading that by 2012 it will
also
be required in diesel powered boat applications. (Boating content

Wow, that's a lot of heat to disperse from the boat, assuming the
converter will be inside the hull, which would probably be the case....

Good point, although there's already quite a bit of heat generated by a pair
of big diesels running anyway. The heat generated by the converters will
obviously have to be carried away through a water cooled jacket or
something.


Man, that's gonna' be a lot of engineering, really a whole new system
will probably be developed. I don't think you would want to run tubing
from the engine cooling system through the hull to the cat, or add to
the existing load on it. Now you are talking space and resources for a
new cooling system and cat, remembering that a breakdown in a cat
cooling system could be disasterous if unnoticed.. It is going to be
huge, hull design and fit may have to be completely rethunk. Oh well,
think outboard... Sorry to ramble, just thinking out loud...

Have you read about the new diesel powered pickups? They go through a
exhaust particulate filter regeneration process every once in a while. When
they first came out, some Ford pickups were exhausting flames that started a
couple of grass fires.

I don't see the big problem. First of all, you aren't "cooling" the
converter (or particulate filter (as it is called in the diesel). All you
are doing is carrying away the excess heat generated by the exhaust gases
and reaction process. A secondary raw water pump or even a dual output raw
water pump (main to engine heat exchanger, secondary to cat water jacket)
with both exhausting through the current, water cooled exhaust would do it I
think.
