A Few More Articles
An invention that could lead to more energy efficient vending machines is described in this Harvard Magazine article. It is a small box that transmits inventory, sales and other information to the supplier’s computer. H. Jeffrey Leonard heads a company (Global Environment Fund (GEF)) looking to deploy them. He describes the current problem:
…Right now, these vending companies have guys in big trucks driving around with their whole inventory, checking and filling the machines. Most of the time they come back more than half full. It’s incredibly inefficient.
GEF aims to increase efficiency and lower carbon footprints of traditional industries.
Traffic engineering done right can reduce emissions. This little piece (from a year ago) Saving Gas — Saving $$ (Ivanhoe Newswire, August 2008) describes the traffic simulation work of Byungkyu Park at the Univ. of Virginia. Follow the information at the bottom to get to more technical material. There is undoubtedly a lot more going on. See also this description of the traffic sensing MARTA project at the Polytechnic University of Catalonia.
And last, a new EJOR article about emission reduction:
