Pollution free transportation has been an engineering goal for many years. One suggestion is to have cars carry nitrogen and operate a heat engine based upon the temperature difference between the air (300 K) and boiling nitrogen (77.36 K). Calculate the maximum possible work produced per unit of high-temperature heat.
