Car safety stats (risk of death vs risk of killing other drivers)

Discussion in 'General Motoring' started by fft1976, Apr 1, 2009.

  1. Rather than guessing we could check information on the intenet:

    Model S will have a range of 160 miles (260 km), 230 miles (370 km) or
    300 miles (480 km) when fully charged, depending on the chosen battery
    option, and feature a 45 minute QuickCharge when connected to a 480V
    outlet. In addition, a battery swap will be possible in less than five
    minutes. [4]

    • 42 kWh battery storage system standard
    • 70 kWh and greater battery storage systems optional

    They say a full charge costs "as little as $4" whatever that means.
    Would be nice if they told us how many kWh for a full charge.

    The battery swap is an interesting proposal, especially if you could
    trade up or down in storage capacity. However, you have to whether
    the infrastructure for on-the-road quick charging or battery swaps
    will ever be installed during the life of your 2012 model.

    If you assume that gas costs $4, and a Prius gets 40 mpg, it will cost
    you ten cents a mile to fuel it. As little as $4 sounds like at least
    $6 to go 160 miles in your S. That is four cents a mile or a savings
    of 6 cents over the Prius. Driven 12,000 miles per year, that is $720
    in fuel savings. That won't even come close to paying the interest on
    the extra $25K cost of the S. Of course the S would be a lot more fun
    to own, but most people cant afford $25K for fun. If they could, BMW
    would be selling a lot more cars.

  2. I appreciate the difference from current hybrids, but the fact is that
    this is a plug-in series hybrid. Afterthought or not, the engine is
    critical to making it viable in the marketplace. And remember, this
    car is totally unproven at this point. Last I heard GM doesn't even
    have a battery supplier yet. At best this thing will go 40 miles
    under optimum conditions. Without the engine, no one would trust the
    car for more than 30 miles and even that much trust might not be
    justified.
    Perhaps we don't mean the same thing by stress. What I mean is
    draining the batteries down low and then fully charging them back up.

    "A lithium-ion battery provides 300-500 discharge/charge cycles. The
    battery prefers a partial rather than a full discharge. Frequent full
    discharges should be avoided when possible. Instead, charge the
    battery more often or use a larger battery."

    http://batteryuniversity.com/parttwo-34.htm

    "Fully discharging your Lithium battery frequently can actually be
    quite harmful to your battery’s health, possibly rendering it
    completely unusable if energy levels go too low."

    http://spicygadget.com/2006/12/24/guide-getting-the-most-out-of-your-lithium-battery/

    Li-ion batteries are not as durable as nickel metal hydride or
    nickel-cadmium designs, and can be extremely dangerous if mistreated.
    They may explode if overheated or if charged to an excessively high
    voltage. Furthermore, they may be irreversibly damaged if discharged
    below a certain voltage. To reduce these risks, li-ion batteries
    generally contain a small circuit that shuts down the battery when
    discharged below a certain threshold (typically 3 V) or charged above
    a certain limit (typically 4.2 V).

    http://en.wikipedia.org/wiki/Lithium_ion_battery

    I understand the principle, I just don't think that pure electric cars
    will have any measurable impact on our energy needs for at lest 10 -
    15 years. That will only come when they are economically viable and
    they aren't even close now.
    The first step to treating it with respect is to never consider it
    benign.
    They are until they aren't. And then they are very bad.

    Nuclear energy and military force should both be treated with great
    respect. That could explain why we have had a major nuclear accident
    and France hasn't (yet).
    I agree.

    I know you've only been independent for about 200 years, but a child
    learns to spell in primary school (4to11 to you), when will you learn to
    spell and then not talk rubbish about "Processing" against dry storage?
    You've a lovely country, it's a shame that your brains don't match up.

    Oh, oil is finite. Many geologists believe we will soon reach "peak
    oil", if we haven't already. Saudi Arabia has never disclosed their
    reserve numbers. The consensus is that we probably have 30 to 40
    years left at current use.

    And, ask yourself what else we use petro for. You know those computer
    chips? They are in epoxy cases. A petro product. You know that
    keyboard I'm hammering on? Yup. How about that poyester suit? Okay,
    there are some things we won't miss.
    With a few exceptions, SUVs really aren't needed. I hear
    protestations about needing the space for the "team", but how often
    does that really happen? Do the parents of all of the kids "need"
    one? The number of times I see a solo driver on my way to work
    (guilty of solo, not guilty of SUV) is outrageous.

  6. Which allows plenty of time to develop alternatives. All it takes is
    leadership.

    True, but as an aside, plastic products can be recycled which minimizes
    the impact.

    Well, SUV(s) replaced the venerable station wagon which was being held
    to passenger car requirements regarding both, fuel efficiency and
    safety. Leave it to Detroit to find a way around such...

    HOW can any "expert" make estimates when new fields ARE being discovered?
    Oil may be "finite",but we certainly haven't found ALL the drillable oil
    fields yet,or began producing from them.
    All the leadership in the world is not going to bring about a battery
    capable of holding enough energy to equal a tankfull of gas or diesel.
    That requires a scientific breakthrough.
    Used oil can be used for making plastics.
    Perhaps vegetable oils and coal (perhaps together)can be used to make them.
    "Detroit" could have made good smaller cars,but instead chose to fight the
    trend and continue making the same stuff.
    AND in the process fostered the import of foreign oil that gave 3rd world
    nations incredible wealth that they used for evil instead of bettering
    their people's lives,and cost US more in security.
     
    Jim Yanik, Apr 14, 2009
  8. Most oil producing countries have already peaked. The US peaked
    almost 40 years ago. Yes, they find new oil fields every year but
    they aren't enough to replace what we suck out in a year. And the
    fields they develop are getting harder and harder to extract.
    Leadership can help us stretch what oil we have. The best thing we
    have right now is conservation. Building mass transit and replacing
    SUVs with subcompacts do not require scientific breakthroughs.
    Most "used oil" is CO2 in the atmosphere. And most plastic products
    (unlike packaging) can't be recycled as a practical matter.
    Only at a far higher price than petroleum.
    If we had just paid for Iraq with increased gas tax, we would be
    driving Priuses and bicycles now.

    Of course,the DemocRATs were the ones who stopped US domestic oil
    production,and currently are holding up any new drilling and refinery
    construction.
    BTW,oil tankers are the biggest risk and have done the most damage to the
    environment,from oil production.
     
    Jim Yanik, Apr 14, 2009
  10. Peak oil like "human caused" climate change is a joke at best and giant
    scam at the worst. There's plenty of fossil fuels left but the point is
    the liquid form is controlled by unstable and often unfriendly nations.
    It's akin to economic blackmail which in turn should provide the
    incentive to replace what we don't have with alternative existing
    technology, (nuclear power), and new technologies.

    (BTW, your comment above was not to any of my statements)

    And that's what leadership can bring about. Battery technology is
    advancing very rapidly at the present time. My guess is that most urban
    tasks could be done with plug-in cars within five years.

    I don't think that vegetable oil should be considered unless you want to
    see price spikes like the ones that occurred with ethanol from corn
    products. Any cartel that can grab you by the short hairs will wring
    your wallet dry if the guv'ment doesn't do so first.

    And caused foreign manufacturers to also create mostrous SUVs. Ever
    follow a CRV? It ain't the Honda that I fondly remember...

  11. Has domestic oil production stopped? I had not heard that. I did
    hear (WSJ) that US refineries are being shut down because the oil
    companies are predicting declining demand.
    Another good argument for conservation.

    Not all of it.The US has known reserves we refuse to produce.
    Nuclear is not going to power automobiles.Not without a decent battery.
    well,the other folks are ones I killfiled.
    sorry,but leadership does NOT bring about scientific breakthroughs.
    Not all vegetable oils come from farming.
    They're working on algae that produce oil.also oils from weeds and other
    non-food vegetation.
    And I wouldn't use them for the high volume auto transportation
    application,but for plastics feedstocks.
    CRVs are small compared to most domestic SUVs on the roads today,and have
    better fuel economy,I suspect.
    Granted,Toyota,Honda and Nissan all make monster SUVs/PU trucks,too.

    I did hear that the shale (shell?) sands of Canada contained about 50%
    of world oil, but at the moment it was to expensive to extract it.

  15. The mere fact that we are talking about oil shale is proof that we are
    running out of oil. A lot of the conventional oil left in the ground
    is going to be very difficult to extract.
     
    Gordon McGrew, Apr 16, 2009

  16. I would prefer to think that it is because oil derived from shale
    deposits are in a friendlier part of the world... But not viable with
    the price of gas less than $3 per gallon.

    Nonsense. There's oil off the California coast,and some of it NATURALLY
    bubbles up from the sea floor. There's oil in coastal ANWR.
    There's oil off the coast of South America,and oil in the South China Sea(a
    shallow sea,too).
    there's still enough places we haven't even explored yet,too.

    our main problem now is the environuts/socialists who hinder our drilling
    and refining,and cost us economically and strategically by making us
    dependent on foreign oil.

    with -today's- processes.
    The use of some of those might even be inhibited by the environuts who want
    us to do without oil.

    Coal power is very safe. Assuming you aren't mining it or live very
    close to a coal ash mound.

    More people were killed in 2007 in coal mining accidents in the US
    than have been killed in ALL US nuclear accidents. Power, weapons,
    research, etc.

    In China, it seems that there are more people killed in coal mining
    accidents in a month than all the people killed in nuclear accidents
    around the world.

    Even if you were right and these is actually plenty of oil (you aren't
    but let's just assume), you think it's ok to keep burning it at the
    rate we do? It's all just a plot of the environnut socialists to keep
    the poor capitalists from enjoying life? Global warming and the threat
    of huge damage to the earth is just another plot, right?
     
    dgk, Apr 17, 2009
  20. There certainly are untapped oil deposits, but they aren't as big as
    you think. If ANWR came on line next year, it might take US
    production levels back to 1999, but nowhere near our 1970 peak. The
    reality of the development process is that, by the earliest time the
    undeveloped US capacity could come on line, we will be lucky if it
    would bring us back up to today's production level.

    There is no magic recovery process. You can't do it with a microchip.
    It is very slow, very dirty and very expensive.
