Calculator to the development of electronic calculators. The Casio Computer Company, in Japan, released the Model "14-A" calculator in 1957, which was the world's first all-electric (relatively) compact calculator. It did not use electronic logic but was based on relay technology, and was built into a desk. In October 1961, the world's first "all-electronic desktop" calculator, the British Bell Punch/Sumlock Comptometer ANITA (A New Inspiration To Arithmetic/Accounting) was announced. This machine used vacuum tubes, cold-cathode tubes and Dekatrons in its circuits, with 12 cold-cathode "Nixie" tubes for its display. Two models were displayed, the Mk VII for continental Europe and the
Plug-in electric vehicles in the United States occupancy. The study concluded that the increased environmental impacts of manufacturing the battery electric technology is more than offset with increased environmental performance during operational life. For the assessment, the study used the average electricity mix of the U.S. grid in 2014. In the 2014 mid-size cars category, the Leaf also ranked as the best all-around performance, best environmental and best social performance. The Ford Focus Electric, within the 2014 compact cars category, ranked as the best all-around performance, best environmental and best social performance. The Tesla Model S ranked as the best environmental performance in the 2014 full-size cars
