Why hasn’t there been more innovations in the cooking gas stove? Its still mostly LPG/Natural Gas I believe, atleast in India. Electric gas does not seem to do justice to a smooth cooking experience. Despite the source being LPG/Natural Gas, the stove probably is not very efficient. I guess I am making an assumption here as there might have been lot of improvements already. Microwave, for example, is a completely separate cooking medium available in most middle-class homes.
