Abstract
The street and ground warming system is used to prevent both the surface and sub-surface of a street or ground from freezing. The system includes a box that is partially buried, and atop of said box is provided a solar cell array that generates electricity to power heating elements. The heating elements may extend from the box, and through the sub-surface and emit heat therefrom. The heating elements may stay within said box and coil around rebar that passes there through so as to enable transmission of heat to a sub-surface structure. Alternative powering means may change the location of the solar cells or eliminate the solar cells all together.
