## Abstract

A method is disclosed for retrofitting a ground surface with electrically resistant conduit to melt snow that accumulates on a ground surface, such as a driveway. A power source carries electrical current to an electrical coil, in some embodiments. A thermostat regulates the electrical current.

## Claims

### Claim 1

A method for conducting thermal energy across a retrofitted ground surface, the method comprising:
determining a cement ground surface region that requires thermal energy to melt ice or snow;
cutting a boustrophedon channel into the cement ground surface region using a cement saw;
embedding a resistive electrical coil into the directional channel such that the cement ground surface is retrofit with the electrical coil;
providing electrical current from a control box to the electrical coil embedded in the lower panel;
generating thermal energy in the electrical coil from resistive electricity traveling the electrical coil; and
emanating heat across the cement ground surface.

### Claim 2 (depends on 1)

The method of claim 1, further comprising filling the boustrophedon channel with a polymeric adhesive after embedding the resistive electrical coil.
