It would be easy to wrap wires around thumbtacks and makes taps off the flat cable. You could mash tacks into the wall, wires leading from the tacks would terminate on nails, and you could cook a hot dog right on the wall!

yeah but i think i will pass the hotdog for now but crank up the amparage on the flat ribbon then you got nice heater in the wall shall we take our work boots off and put the feet up to feel the " warm " wall ??
but no sun of course.
anyway that the idea how it can be abused very easy
