  • Tesla Motors to add charging stations in NYC parking garages [View news story]
    NYC has a grid mix including 65% is listed dual fuel. The fuels are Oil and NG
    So their grid is powered from 24% oil to 89% oil with NG from 8% to 73% of the grid. This leaves 3% for renewable energy.

    Assuming you have 50% of the dual fueled generation as oil (65%/2 = 32.5%) you have over 32.5% + 24% = 56.5% oil fueled EVs. With a 6% distribution loss on the grid putting you over 60%.

  • Tesla's Insane Mode Of Pricing [View article]
    Beginner investor
    "Care to do a similar analysis on inefficiencies in oil/gas exploration, production, distribution etc. to get the fuel into your ICE in the first place?"

    Most of what I've seen is a bit below this at 18% - 20% an this is a bit old at 2007 but it should be close.

    Pumping a gallon of oil out of the ground, getting it to a refinery, refining it to gas and getting it to a gas station all in is "about 21%."

  • Why Free And Unlimited Supercharger Access Can Devastate Tesla [View instapost]
    Every vehicle Tesla has ever sold has the promise of unlimited superchargers free, for life. I expect nearly every MS ever sold up to now, will end up a taxi near a supercharger station. 22kW chargers may be only a grand but the electricity in Europe is $2,500 a year, wholesale.
    Multiples of that for Uber drivers and other small fry.

    "Which is very different to individual users hogging Tesla SC stations to avoid local charging."

    So it's OK for businesses to hog SC but not regular customers?

    Excuse me?
    When Elon sold the MS to regular buyers. Part of the purchase agreement was free SC for life. An incredibly stupid offer but Tesla/Elon made it. The Tesla stockholders embraced this claim as completely acceptable and doable. After all, the electricity was going to come from solar panels on the roof of the SC. Batteries would be installed for night time charging. Tesla would get no bills for electricity from the SC stations at all.
    All other opinions on this stupid offer were ignored as naysayers.

    Elon has, just realized/announced what Tesla is on the hook for. Elon made a promise of, free SC for life, to these people and on that basis, sold them cars.
    The best defense being a good offense... Elon attacks the buyers. He is using social pressure to try and block them from making him live up to his own (idiotic) promise!
    (If this was an ICE manufacturer, Imagine selling a car with a guarantee of free gas for life, then months/years later coming back to the buyers saying "But but you are only aloud free gas when you go on long trips! Not around where you live and work! Oh the screams we would hear.)
    Hogging the SC indeed. But back to Tesla.
    You too are attacking MS owners. (Part of that social pressure Musk wants. Good job, you are following the leaders orders, well.)

    These MS owner's sin? Buying a car based on the agreement Tesla/Elon made with them.

    I wonder how far this will go?
    There are always extremists.

    "The pollution created by the manufacturing and disposal of > Batteries, inefficient solar farms, and tech intensive/expensive wind generators will someday exceed that now caused by coal."

    While you may be technically correct there may be more pollution at some point in the future it is unlikely to cause the damage of the air pollution wafting around the planet from coal plants.
    While these things need proper disposal or potentially recycling the reach and breadth of their pollution is in general more local than coal.

  • Why Free And Unlimited Supercharger Access Can Devastate Tesla [View instapost]
    Value

    Interesting information: Free for life was unsustainable from the beginning. Despite people claiming otherwise.

    Renim
    I do agree with your first point.

    1stly; to understand free supercharging, you need to understand commercial electricity rates, not residential rates.

    If you look at the chart, (By my eye) on average wholesale prices are about 10 cents per kWh in Europe.
    http://bit.ly/1CLX2Ga

    Which puts it in with the US at $20K to $30K per car. Still wildly unsustainable.

    2ndly; there is large difference between domestic users using supercharging for local use vs commercial taxis with 22kW nighttime charging. Unless a Taxi is 2x12hr shift, the taxi has the opportunity to fully recharge a battery using a mere 22kW AC charger during off shift time. So taxi's using free supercharging is not a burden either, - as long as they also do pre dawn base charging.
    So if the Taxi is 1x12 hour or 2 x 8 hour shifts, its still is all good for Tesla. For Taxi use a Tesla gets around 500km on a single daily nighttime charge. and that's before any use of supercharging for long distance driving.

    As to the second point; Obviously this is not what is happening.
    Did you read the article Value linked to?
    "AMSTERDAM—Matthijs van Seventer won’t take his Model S electric sedan to the Tesla charging station in the southeast part of the city if he is in a hurry. The chargers are typically loaded with taxicabs serving Schiphol airport."
    http://on.wsj.com/1CLX4Og

    Tesla now has enough of a problem that :
    1. The CEO is spending time talking about it at the annual shareholders meeting.
    2. They are changing the wording on Tesla's site in an attempt to stop it.
    3. the problem in Germany is bad enough to be showing up in an American paper WSJ.
    4. Finally it appears the airport bought the MS for taxis. if there is a free for life supercharger station at the airport, why do you think the airport (or any other fleet buyer) would or has installed any other method to charge them?

    "You also may want to revisit your 60% fossil fuelled grid numbers, I don't think your little country is that far behind Canada - we use less than 30% fossil fuels and somewhere near 60% hydro power (as of 2012). "

    "Sorry. I must of forgotten that your country represents the ENTIRE world without variation. "

    Pretty funny, you ask fiwiki for the US numbers. When you don't like the answer, you change the question and pretend it was his error.

    So what are the global grid numbers?
    They are worse than the US for fossil fuels.

    Coal 40%
    NG . 23%
    Oil .. 4%

    67% fossil fuels in 2012 that latest word figures available. Same as the US in 2014.

    BTW your #3
    "The fuel used does not change throughout the cars life."

    More e-Fuel Development From Audi
    http://bit.ly/1TI2Kgp
    "CO2-neutral synthetic fuels is one direction Audi is aiming its fuel researches."

    While this is only a small pilot project more is going on.

    "Audi affirmed it is also conducting joint research into the synthetic manufacture of Audi e-gasoline with Global Bioenergies of France; and a joint project with U.S. company Joule is striving to produce the synthetic fuels Audi e-diesel and Audi e ethanol with the help of microorganisms."

    http://bit.ly/1TI2Kgr
    "Audi engineer’s conclusion: unlike fossil fuels, the composition of which varies depending on their place of origin, synthetic Audi e-fuels are absolutely pure fuels. Thanks to their chemical properties, fewer emissions are generated when they are burned.
    Audi added these e-fuels do not contain any olefines or aromatic hydrocarbons; as a result, the synthetic fuels assure a more effective mixture preparation process, cleaner combustion and lower emissions."

    CO2 neutral and fewer emissions.

    "It has been pointed out to you more than once but here it goes again (maybe it'll sink in a bit if you hear it enough times)."...
    "But fuel used does not change throughout the cars life."

    How many times have you claimed that?

  • Meet the new U.S. automobile startup [View news story]
    The Corbin Sparrow was an EV. They were about to bring out an ICE version. To that end they had bought a business with a factory in Canada. Unfortunately (As I understand it) the company they were buying had accountants better at hiding their problems than Corbin had accountants trying to find out what they were getting. The day the company was to begin production of the ICE version Corbin instead shut down.

    There is a newer version of the EV version resurrected from the bankruptcy called Myers Motors.

    " In the worst US places that burn fossil fuel to deliver electricity, the energy delivered to a Tesla uses half the emissions of a car. I have done the math. Have you?"

    While Java has probably no backing on what he is saying. Clearly you have not done the math or anything else.

    Here's another from the National Academies of Sciences.

    http://bit.ly/1I3d4wG
    "EVs powered by grid-average electricity also have greater negative impacts than do vehicles powered by gasoline."

    "Scenarios with substantially decreased air quality-related health impacts compared with gasoline include gasoline hybrid vehicles (30% decrease) and EVs powered by natural gas or by WWS (50% and 70% decrease, respectively); scenarios with substantially higher damages than gasoline include corn ethanol (80% increase) and EVs powered by grid average or coal electricity (200% and 350% increase, respectively). "

    A grid powered EV using the average us grid causes twice the damages of an ICE. An EV on coal causes 3.5 times the damages of an ICE.
    Yes powered by solar wind etc an EV can be cleaner but for most people they won't be.
    Probably you have only looked at evidence based on CO2.

    "If you did, you would find that ICE street cars are about 20% efficient, due to the laws of physics, so they can't compete. Only other BEVs compete with Tesla."

    However the grid is only about 30% efficient 65% loss at the powerplant and 6% more lost in the distribution to your EV. Charging an EV is about 80% efficient. (Tesla MS, as close as I can tell, is 75% and a Leaf at 84%.) There is the loss in actually using the vehicle. About 90% efficient.
    Then you get into smaller things such as the mining and transportation of coal, uranium etc.
    Supplying an ICE with gasoline has an all in efficiency of 82%.
    Basically efficiency is a wash. A good ICE/hybrid is higher in total efficiency a bad one worse.
