Why should gasoline still be held up as the gold standard for energy storage? Its sad that just because LiFe is the current state of the art in battery technology that we have to be impressed with it. Does anyone know the energy storage capacity of the batteries in the Lunar Rover that the Apollo missions took to the moon 40 years ago? Even if it was only equivalent to LiFe, its a crying shame that we haven't managed to improve capacity, weight and/or cost in two generations.
