A friend of mine, who is a cathodic protection engineer, states that in the 
cathodic (corrosion) protection business,  he installs sacrificial anodes on 
buried gas piplines to protect against corrosion.  He also states that  current 
flows from the positive to the negative pole but electrons flow from the 
negative to the positive pole!  -  Sherrill   k4own
