A $700 Million Bet on Electric Cars

This has major banks behind it, Israeli investors, the Israeli government (which has a defense-based incentive to do this), and the Danish government (whose country gets 20% of its electricity from wind power, giving it an environmental incentive to do this). Also, Renault, a $50 billion automaker, says it will have conventionally priced electric cars available by next year. The key concept here, which I think it's extremely important for the other automakers to recognize and adopt, is the interchangeability of batteries between vehicles. This will allow for quick changes of batteries at gas stations and extend the range of electric vehicles at low cost.
