Dave,
No, I don't think so.
If the anode is connected to the steel tank, the magnesium anode will react
with the steel it is in contact with. I believe that the reaction will take
place between the magnesium and the steel center rod it is formed around,
instead of between the magnesium and the water. At least that's how it
looks logically to me.
Back to my initial logic.
Putting the anode at the bottom of the tank, provides a long contact area,
and any water at the bottom of the tank would provide that electrolyte.
Now I am back to thinking. . . . . Which is better?
Jack

Jack,
What are you going to use for electrolyte, fill the tank with water?
Otherwise, it will be just like a battery with no electrolyte in it.
