I am looking for an overview of Cathodic Protection.  Specific
questions would include:

o  Definition
o  Market summary 
o  Market trends, drivers & value proposition
   o  Current solution providers (key industry players)
   o  Technology solutions
   o  Non-technology solutions
   o  Currently available products
o  Expected future developments for products in the industry
o  Approximate market size

My primary interest is in U.S. or North American markets, but
Worldwide data would be interesting as well.
