Induction stoves are the much better option here. They will only heat up ferromagnetic material (i.e. actual pots and pans) and most can sense when nothing is on them and turn off automatically.

True, but that's a much bigger purchase I guess, and many ppl would prefer gas if that's what they are used to.
