promissing futureNano would have great retail sales even if it didnt have a more powerfull battery, longer lasting battery, safer battery, cheaper battery, faster charging battery, battery withstanding higher temperatures etc, There are not enough auto battery manufacturers to supply the world market as it stands. Whos not going to want the battery with the upside nano has in its product. T.V. commercials are now comming out with electric vehicles of any type. VERY PROMISSING
