    surferbb: you may already be a millionaire. Your 100 shares of Tesla is worth about 2,040,000 pennies, 2,400,000 yen, and about 1,240,000 roubles. Congratulations !!

    runiter writes and asks: " ... Why wouldn't it be able to haul your boat? Your Sierra has only 420 horsepower where as Tesla P85D has 691 horsepower. "

    Because at 691 hp the battery will be depleted in less than 10 minutes, if it, or the drive train, haven't blown up by then.

    And if the Tesla "only" put out 420 hp, the battery would be depleted in about 16 minutes.

  • Ripping The Shorts' Faces Off! [View article]
    AltEnergyGuy (aka TheMortgageBanker, TheMortgageGuy, user#####, etc.) writes: "Anyone looking at deliveries is not very smart. Focus on production. "

    OK. So if ICE manufacturers and dealers have lots are full of Fords, Chevys, Caddies, Camrys, etc, they're doing good as long as they keep producing, even if no one is buying their stuff. Check! Got it!

    Or, does this measure of goodness only apply to Tesla?

    Isn't that exactly what Musk (and Tesla) is doing by wrapping himself in a green blanket while selling a car that can produce an "insane" 700 hp?

  • The electric vs. hydrogen debate just got interesting [View news story]
    S Dalal writes: "The temperature outside is currently 9F and high is 22F. Lovely weather to stand and fill gas while smelling some fumes. Even at 2$/gallon it costs me more than double for gas vs electricity too. "

    So, if you needed to get to Washington DC, or Baltimore, or Philly from Charlottesville Va, how long would it take you in your Leaf? Spending 2 to 5 minutes in a gas station would seem a really good deal compared to the extra time it would take with your EV.

  • Why Is Tesla Throttling Production? [View article]
    LDI writes: " ... If they really had a demand problem they would HAVE to advertise because, you know, if they can't sell cars then they are out of business!
    Conventional advertising is the best way to stoke demand.
    They aren't doing it because they don't have a demand problem.
    Simple. "

    Tesla is making a huge mistake by not advertising. They need an ad here and there to raise some curiosity and stoke some interest.
    They may not have a demand problem with much of the affluent class that knows all about Tesla from sites like this and other investment information sites that have stories about Tesla ad nauseam. But what about the people that are supposed to be buying the EV for everyone, the Model 3?
    By the time Tesla has it available, people will see all sorts of EV ads from GM, BMW, Ford, Nissan, ... . When Tesla finally arrives, it is they who will seem to be the copycats, late comers, and interlopers. By then it may be too late.

  • Tesla Could Sell A Million Vehicles Per Year By 2020 [View article]
    Jonaskinny writes: " ... Personally if Tesla got 400 miles on a readily available 3 minute charge I would not be motivated to pay more for further range. "

    Let's see now. 400 miles at a generous 4 miles/kWh requires 100 kWh of energy. To inject that into the battery in 3 minutes, or 1/20 hour, means it is charging at a rate of 2,000 kW, or, 2 MegaWatts. Charging at about 400 volts means a charging current of about 5,000 amps; for three minutes. Good luck with that.

    wwt1 writes: " especially considering that many of the current owners are multiple offenders....
    You are so arrogant it's incredible. Is that some kind of super power you were born with? "

    Go to the TeslaMotors site and some other sites and you will find numerous participants who own more than one Tesla.
    One owners owns at least four and is (was) eagerly awaiting his fifth - a D model. Another frequent contributor had an accident backing out of a parking spot and, instead of repairing the car ($20K -$30K), sold it as-is so he could buy another new one: by the way, it was his wife's car, so we know that family had at least two.
    Many current owners ARE multiple "offenders".

    Pete VV writes: " ... If you happen to drive 200 miles straight and need a charge, 15 minutes will do. "

    True. But only if you're driving towards a supercharger. And if not, and you are about to run out, be prepared to spend an hour, or more, for 60 miles worth of charge.
    Like the National Park Service, which offers a gimmicky "passport" that can be stamped at every site visited, maybe Tesla can also offer such a "passport" and see if a driver can visit every supercharger ... and then get a T-shirt.

    The green and black bar graph could just as well be showing the resolution of an improved Hi-Def television screen with 1080 by 2020 (instead of 1080x1920) pixels. Malthus would be proud of this contributor's "irrational exuberance" analysis.

  • GM To Deliver Inexpensive 200-Mile EV 2 Years Ahead Of Tesla [View article]
    doubleE wrote: " The S40 reservation holders get their cars at the promised price. "

    Yes, they got "their" cars.
    But they weren't the S40s that were ordered; because they were never produced. To avoid a PR debacle of stranding some of the earliest adopters and Tesla fans and believers (some of whom could barely afford even the lowest priced Model S), Tesla gave them the higher priced S60 with a purposely reduced capability at the originally ordered price. That was a good deal for the buyers, but they got it only because Tesla really had no other choice.

  • Using Tesla Math, Is The Jeep Brand Worth $100 Billion? [View article]
    capt601 writes: " ... How does your ICE car so under comparable conditions? Think even AAA did a study hat showed ICE cars lose 20-40% of their range as well under similar conditions but hey you knew that. "

    An ICE has unlimited range since, in almost all cases, a gas station is very nearby and a refill to the full range, under even adverse conditions, is minutes away. And even if a gas station is far away, a couple of gallons of gas can be delivered to the ICE; but that energy can not be so easily delivered to an EV. That's the point: range is not an issue for the ICE, it is for the EV; " but hey you knew that", didn't you?

    PVGO writes:
    “ … And then you burn this gasoline (as instructed in the car owner's manual) at 20-25% efficiency to move your wheels.
    That's *really* smart, isn't it? “

    This is yet another example of someone not knowing what they are talking about and spreading BS.
    PVGO, do you even know what that 20 – 25 % means?

    When a gallon of gasoline (as an example) is burned it is converted to a very hot gas that contains about 30 kWh of THERMAL energy. THERMAL ENERGY is in the form of rapid motions of the constituent hot gas molecules. Then a miraculous device (in my opinion), called a heat engine, converts some of that thermal energy of the hot gas into about 6 – 7 kWh of MECHANICAL energy. Mechanical energy that can move things and can do work. What you want to do.
    The 20 – 25 % efficiency, mocked at, refers to the ratio of the MECHANICAL-ENERGY to THERMAL-ENERGY. Talk about comparing apples to oranges. By the way, the reason that “only” 20-25% is converted is because the cooler, but still hot, gases that are exhausted by the engine still contains a lot of energy (that can be used to do things like heat the cars interior - also, cogeneration in power plants) and the only way to get it all out is if the working fluid (gas) would have its temperature reduced to absolute zero, which ain’t gonna’ happen.
    Comparing this to the efficiency of 85%, 90%, 95% efficiency of an electric motor, that converts electrical energy to mechanical energy, is a false measure because lots of energy is used to generate the electricity in the first place. The universe is unfair; converting electrical to mechanical seems more "efficient" than thermal to mechanical if you carefully select the location of your "scenic" overlook.

    If you have solar panels on the roof then, at best, only 40% of the solar energy that makes it through the atmosphere (another big loss not counted here) impinging on the panel is converted to electricity. If the panels don’t move to follow the sun, then that 40% is greatly reduced by the cosine effect and, I’m guessing, you only extract, at best, about 25% of the solar energy available at the panel locations. Not much better than an ICE.

    If the electrical energy is from a power plant using coal, NG, or other fuels, the efficiency of generating the electricity is, maybe, about 30% and after transmission costs, the energy of the electricity at the plug is also only about 20-25% of the thermal energy in the fuel.

    If the electrical energy comes from a hydro-plant, the efficiency is much less than believed if the same measure is applied to it as to the burning gas. Take the Grand Coulee dam on the Columbia river in the Northwest. A glance at Google Earth shows that the elevation of the water in the upper part is 1285 feet (image of 7/13/2013). Immediately below the dam the water elevation is at 970 feet. The head of water of 315 feet represents the potential energy of the water in the vicinity and from which the electricity is generated. But the base is still at 970 feet, so there is 3 times more potential energy (with respect to sea level) still available and that is “wasted” by this hydro plant. The efficiency in this case is 25%. Obviously this is a silly comparison, but no worse than comparing the mechanical energy extracted by an ICE from the thermal energy in the ICE fuel.

    “That's *really* smart, isn't it? “

    Yeah, it is.
