    This is the subject of "well to wheel" comparisons. How much does it help,
    if any, to move the generation of the power from one place to another,
    including the inefficiencies in transport.

    Time of day metering might be mandatory for an Electric car owner, charging
    up at night.

    Solar power could be used for charging the electric vehicle, in a home
    setup.

    Nuclear/Geothermal/Hydro could be the source of the electricity, reducing
    the need for non-renewable and foreign resources.

  2. As a historian I would remind the NG that the ICE was seen as a clean
    alternative to horse power and the tons of manure the horses left on
    city streets every day. Manure was sticky mud when wet and choking
    coulds of dust when dry.

    Replacing all of the cars currently on the road with an equivalent number
    of horses would lead to environmental problems very quickly.

    Electric wins out ...

    A pure electric vehicle might average 300-400 Wh/mile. Add charging
    inefficiency and it'll take a bit more, but let's use 400 Wh. My
    marginal electric is about $.07/kWh, so it's about $0.028/mi, or
    about 36 mi/$. Compare to gasoline at about 10 mi/$ ($2.40/gal and
    a 24 mpg car).

    Efficiencywise, using 41% average electrical efficiency, it's about
    1 kWh(original fuel)/mi compared to about 1.6 for crude oil to the
    above car.

    But if everyone did it, we'd have to up our electrical capacity by
    quite a bit! ( I don't think just off peak charging would do it).

    What you're forgetting, typical for this thread, is that the Insight is not
    rated at 60/71 USMPG while doing 10.6 second 0-60 times.

    Certainly you don't think that the Smart is getting 51mpg during the run?

    Why would you point out that the Insight doesn't get EPA rated mileage
    during an acceleration run unless it differs from the Smart car?

    Given that the Insight doesn't get good mileage during a 0-60 run, do you
    think it is better than the Smart during a 0-60 run, with the Smart taking
    twice as long for the run?

    especially if you consider my civic has 108 horsepower. that would be a
    long horsedrawn carriage.

    Not after the first run or two which is about all you get before a battery
    recharge is required. Always ignored is the fact that hybrid efficiency
    drops dramatically with ambient temperature - another problem the Smart42
    and plain old gasoline ICE cars don't have. This particular problem is
    mitigated by warming the batteries in the same way the passenger compartment
    is warmed. If it's cold outside, you can plan on hybrid ICEs running all the
    time - even in city driving. Same thing happens with the batteries get too
    warm except then they use A/C which, again, requires the ICE.

    Wouldn't be able to go 85, either. ;-))

  12. You bet! Not what I was suggesting, of course. Too expensive to convert
    all the gas stations to selling hay & oats, just for openers, plus
    there's a severe shortage of blacksmiths to keep the horses shod.

    This is a silly point.

    Motor Trend did eight back to back runs to deplete the battery, and
    then they still got a 13.1 second 0-60.
    I don't notice a drop in 20-30 degree weather. Dramatically colder
    climates might see different results. I do see a drop in MPG with the A/C
    running, whether in the summer to cool the car, or the winter to defrost.
    The ICE does not auto-stop when it is cold. I haven't noticed that cause a
    drop in the mileage. I think its contribution is small for normal driving.
    It might be a plus in congested city traffic, but there I find that the
    Honda runs anyway, because it has to get up to 10mph before the auto-stop
    is enabled. There is no A/C for the batteries in a Honda. It gets a flow
    of air from the passenger compartment, whatever temp that might be.

    There is a separate cooling/heating unit in the Escape. I think it is a
    separate electric-driven unit, so it doesn't require the ICE to be running.
    I can hear it running after the ICE shuts off. I don't know that I would
    call it A/C, since it uses coolant and not freon.

  15. Do you think the Smart gets 54 mpg irrespective of conditions?

    In California u can get a Civic NGV and get an NGV home refueling
    appliance installed to get a low-pressure fill from your house natural
    gas line. That's good for about 100 mi -- for a complete fill-up you
    have to go to NGV station. One driver/HOV lane eligible, less
    pollution, more supply + tax rebate (but fuel not much less $$). But
    since carpool lane might open to Hybrids it isn't very popular. Plus
    there isn't much trunk space.

    The home fueling option is very recent. Prior to that, I can understand
    why there was very little market outside government agencies.
    There is no natural gas in my area, so it isn't helpful to me.
