It is time for some good news. In recent weeks there has been a spate of announcements about plans to develop electric cars and much better batteries to power them. Although few new models will be ready for sale in a couple of years, by the end of 2007 there should be many technology-proving prototypes driving around. This in turn should give us better insight into how soon electric vehicle technologies might become available and whether there will be limitations such as prohibitively high cost, inadequate performance, or shortages of specialized raw materials that might prevent their widespread adoption.
