No Longer in the Center

So the commercials for the new Nissan Leaf got me thinking about how far away we are from large scale conversion to electric cars (or some version of electric-motor-drive car, such as the hydrogen fuel cell cars we keep hearing about). The arguments in favor are simple. While the internal combustion engine is relatively efficient it cannot be as efficient as large-scale energy generation just because of scale. Although, the power has to come from somewhere, plugging a car into your home outlet would be significantly more efficient (and therefore less polluting) in the long run than running a small-scale power station under your hood. Designing a car around a small (non-explosive) and quieter electric motor also provides infinite possibilities for improvement in safety, aesthetic and spacious design. Contrarians that suggest the technology can't be advanced to the level of internal combustion engines (in terms of distances per charge, torque etc.) are obviously ignorant of the ...
