But Why? What is the reasoning behind this not being made a reality now? Its simply money. we are wrecking this planet, and its all because the research into other means is too expensive, and will remain so until oil runs out. Its not that we dont have the technology to do it, we do. Its just not financially practical to put the means into place. And this is another reason, Mass Production. The combustion engined cars are cheaper to produce, therefore a bigger profit margin is made, and people can afford to buy them. Electric cars with this new technology would be too expensive to buy at the moment, and its too big a financial risk to say "right, we're going to make thousands of these and MAKE it cheap to produce". No mass production company are willing to experement with it, just specialist companies that can only produce them in small numbers. These small numbers mean they are expensive, and immediatly price themselves out of the market. Money Money Money. Give out an unlimited supply for research and production, and i bet a prototype could be knocked together in 6 months. Perhaps not electric, but something renewable.
