> and has low power density Wikipedia: "They have one of the highest energy densities of all batteries ... an electric vehicle with aluminium batteries has the potential for up to eight times the range of a lithium-ion battery with a significantly lower total weight." > Because it is highly inefficient I just read in the 20 - 30% range. One, that's a lot better than a gas burner. Two, your magical 93% doesn't account for the efficiency of the source of the electricity. Over 40% of the electricity produced in the US is from coal. The average efficiency of a coal plant is around 30%. Coal plants are also the #1 source of greenhouse gasses in the US.
