Electronics using heat rather than charge for carrying information!!? http://www.scientificamerican.com/article.cfm?id=magnetism-confirmed-to-control-the-flow-of-heat So the article states it's been confirmed that magnetism controls heat. It also mentions that future electronics could use heat as an information carrier instead of charge. How would this work? What does that mean for electrical engineers? Would EEs begin learning heat information signal control in universities or would some other discipline take over?
