A system for removing snow and ice from a surface that includes a fan and
a heating element contained within a hollow cavity open at one end, and a
hollow duct positioned above the hollow cavity. The hollow duct is open
at both ends; one end is positioned directly above the open end of the
hollow cavity, while the other end leads back into the hollow cavity
through a hole on the other side of the heating element contained
therein. The fan blows air past the heating element and out the open end
of the hollow cavity. The heated air melts any snow or ice with which it
comes into contact. At least some of the heated air that does not contact
any snow or ice is drawn into and through the hollow duct, and back into
the hollow cavity where it may be reused.
