This is a small robot snow/ice remover to clean your driveway and footpath. It's a small tracked vehicle, and the tracks are copper-plated. The engien would be encased in a copper sheath, with heat pipes connecting from the engine to the copper tracks transporting heat to them, to melt the ice/snow underneath.
Pure
copper is too soft/ductile, so it would have to a copper alloy with adequate hardness, yet still highly thermally conductive.
This machine would work slowly until it had traversed every square inch of your driveway/footpath to melt all the snow/ice covering them.
