21st Century Rods for cold weather

[Red Childress]

How difficult would it be to construct a casting or spinning rod that would house maybe 2-4 "D" size batteries in the butt which would be connected to a wire that flows into the guides to prevent icing??

If it would be semi-practical to construct, would a few D size batteries deliver enough heat to keep the guides clear for an 8-hour day of casting??

Maybe a screw-in rear cap section on the butt to keep the batteries snug and a highly conductive metal to reduce loss of heat on the way to the guides??

Would the innerflow rods be more useful in this situation due to only having to keep the end guide ice free??

Been thinking about something like this for years but I have little knowledge on the practicality of such a contraption.

It is OK to tell me I am crazy.
