Re: Not enough range.
However, the diesel in a diesel-electric is tuned to run most efficiently at exactly the same speed as required to run the generators. It is actually just as efficient as a full-scale power plant (ignoring scale issues). However, it has virtually NONE of the power transmission losses. That's why almost all long-haul freight, world-wide, is powered by diesel-electric. Including shipping. It is quite simply the most cost efficient method of moving massive quantities of stuff from point A to point B.
Power line losses in any National Grid are a very, very large part of total operating expenses ... and the more electric cars you plug into said grid, the higher these losses become. Hybrid is the only logical answer.
