Although, batteries are coming down in weight, increasing in energy density and lowering in cost every year. The latest technology, now in large scale testing will, if it holds up, more than double the energy density, while lowering the cost by 2/3. At that point a 300 mile range might come down to 25 -30 thousand and be a more practical op

Volt battery @ 435lbs ='s 1 gallon of gasoline @6.8 lbs...

We need a 64x increase in battery techology to get the same power density, I am not holding my breath for all those breakthroughs...

Electric motors are several times more efficient than gasoline engines in converting energy to forward motion, so you don’t need to carry as much energy. Also, you can afford to carry more battery weight, since you are giving up the heavy gasoline engine and transmission.
