  • Battery Recharging: Why Is Tesla Not Going Wireless? [View article]
    wfa writes" ... Could you please inform us how the sun orbiting the galactic center in any way affects solar panel electricity production which seemed to be your initial point? ;-) "

    (1) Try reading my comment to see what I was responding to.
    (2) " which seemed to be your initial point? ;-) " No, that was not my point. I made no point about the solar production of electricity. My point was to point out the ridiculous, uncontrolled rhetoric, of some people who can't stop themselves. For example: "Oh and the Earth still went around the Sun and the sun went around a spiral arm of a far flung galaxy and so far this is the only dot of life known to man with naught but vacuum and a few dead rocks and burning plasma for lightyears in all directions. And for some reason some of those life forms don't seem to think that this situation is at all precious." :-)

  • Tesla Has A Graphite Problem [View article]
    JRP3 writes:
    16,000 tons of coal used by refineries in 2014, down quite a bit from previous years. "

    Sounds like a lot!
    Let's see.
    16,000 tons divided by 365 days gives about 44 tons per day. Typical rail coal cars have a capacity of about 100 to 120 tons. So, all the refineries in the US, combined, use about 1/3 the load of a coal carrying rail car. On average, one rail car load of coal can supply all US refineries for three days.
    That's impressive.

    oildeathspiral writes: " ... Even your snarky answer is off base. It takes a fair amount of electric power to turn oil into gasoline or diesel. Various estimates put that figure at around 5kw per gallon. Even if it's half of that it's not "infinitely more". "

    The electricity and steam used in processing petroleum comes from a portion of the petroleum itself (about 15%) and petroleum "waste" products of the distillation process. Oil refineries usually don't make the steam or electricity themselves but hand it off to nearby "companies" that are often closely related or subsidiaries. There is no need for "outside" electrical power.

    Cecil Rhodes writes: " @Zelaza ... Prove that the sun is moving or anything else is on that list that moves."

    The speed of the Sun about the galactic center of the Milky Way is:
    220 (+/- 20) km/sec.

    See, for example:

    As for gears, wheels, cooling fluids, what can I say?

    Cecil Rhodes smugly writes: " ... Note that the only moving part in the entire chain is the rotor inside that motor at the last step. "

    Actually, you forgot the moving sun, the moving gears, the moving wheels, and the moving cooling fluids and pump components required to keep this eco-system from overheating. And you can't get too far from that "Wall Socket."

    doubleE writes: " You miss the point completely . Wireless charging only needs a six inch or smaller air gap . Wired charging needs a much longer cable for practical reasons. "

    How many feet of wire (capable of handling large currents) in each of the coils of wire on either side of the six inch gap? I'll bet it's more than the cable in a direct connection.

  • Tesla Motors Model 3 launch pushed back to 2018 [View news story]
    Dave_M writes: " ... Really? I thought paying $200/month for gasoline would be a pretty big burden for drivers ... Leaf owners only pay $50/month for electric fuel to drive the same distance. I'd say that's less of a financial burden for the middle and lower income consumer."

    I'd say that 99% of middle and lower income consumers (who don't own EVs) continue to pay the $200/month and are not at all helped by the savings of the 1% (or less) who can afford an EV (affording an EV includes having a home and a garage space for at home recharging.) And it is these 99% who also pay road use taxes (through the gas pump) who are supporting the 1% who don't pay road use tax even though the heavier EV (battery) is churning up paved roads much more aggressively. And the tax rebates ($7500) people like Dave_M received are also payed for by the 99%.

    " ... or the Jiffy Lube franchise owners, or the ICE parts makers, etc."
    Wait till you have to pay for Tesla parts; that will be fun to watch.

    As an aside. I think that when a Supercharger is used, the Tesla driver (or Tesla) should be charged the state tax on a mileage equivalent amount of gas (i.e., if you Supercharge 200 miles worth of electricity, which would be comparable to at about 7 or 8 gallons of gas, the driver (Tesla) should be billed the tax on that amount of gasoline.)

  • Tesla takes out $500M-$750M credit line [View news story]
    WSRU writes: " ... You get the price on the website and that's it. That's how car buying should be. Haggling over price just hurts people."

    You cannot possibly believe this.
    So much for the free enterprise system and market forces determining the price and value of goods and services. So when Tesla buys giant rolls of sheet aluminum they should pay the full price demanded by the aluminum producers and not haggle. When it comes to buying the raw materials for the gigafactory Tesla should just pay the demanded price and not haggle. Did Tesla do any haggling with the several states that tried to get the gigafactory? When Tesla tries to hire a promising employee the employee should accept the offer and not haggle. The list goes on and on.

    "Women are usually taken advantage of when buying a car."
    Sexist much?

    "TSLA doesn't do that to people but car dealers do it every day." Try buying a car part from Tesla and see what happens. When the warranties run out people are going to be in for some real shocks.

  • Tesla Motors Model 3 launch pushed back to 2018 [View news story]
    78silverannvette writes and asks: "Looking at the slide, there is no date on it. End of 2017? early 2018? Where does it say 2018 on that slide? What am I missing? "

    Really? You don't see 2018?
    OK, look on the graph. See the box with the super size font that says $35K in big red letters? Right below it, on two lines, read "200 MI-RANGE PLANNED FOR 2018" Also, see the red arrow pointing to the red diamond with the Tesla symbol just to the left.

  • Tesla spotlight falls on Model 3 lineup and credit ratings [View news story]
    WSRU writes:
    " They will be shipping $35k versions but I'd guess only 10% of the Model 3 sold will be the base model. Most people are going to get upgrades. "

    There is no basis for this statement as the car (apparently) hasn't even been built yet. Comparison to the 40 kWh Model S fiasco comes to mind.


    " ...The problem with the S40 was the battery was too small for that size of car. Nothing was wrong with the car at all, it just didn't have the power. "

    It also didn't have any useful range for a $60,000 car, $50,000 car, or $40,000 car, or etc. Tesla knew from DAY ONE that the Model S, with the 40 kWh battery couldn't do squat, and yet they promoted and advertised this car for (perhaps) two or three years and accepted $5,000 deposits from the most devoted EV adherents only to cancel the car. The base Model 3 is supposed to cost about half the 40 kWh Model S yet get far more range. It's looking like the Model 3 will be more like the now canceled 60 kWh Model S which cost $70,000.
    Like the 40 kWh Model S, the $35k Model 3 is a bait and switch car. As you try and order it, it may be strongly suggested that you really want this or that upgrade and, besides, the $35k car won't be available for X-many months later than the $45k-$50k minimalist Model 3.

    Please list or link to two of those "numerous times."
    It took two days for someone else to link to an unreliable source (a random blogger infatuated with Musk and dazed by common everyday technology and techniques.) Apparently you don't have a link but not at all reluctant to troll by making unsubstantiated claims using inflammatory language. You do this all too often.

    WSRU writes: " The $35k is the target for the base model that a small % will buy, just like the S60. I imagine most people will be in the range of $40k to $50k due to adding options. If Musk is smart, he won't be shipping any units at $35k the first year and focus on the performance version of the car first. "

    In other words, following the same strategy used for the Model S 40kW, which never shipped, the $35K Model E is touted only for publicity purposes and will also never ship.

  • Will Tesla's Model 3 Compete? [View article]
    Logical Thought writes: "... For that alone you can probably add 300 pounds to the Model 3, and then another 400 pounds for the bigger battery and 200 pounds for the heavier parts needed to accommodate the extra weight. Tesla will be EXTREMELY lucky to bring in the base Model 3 at 3700 pounds. "

    Let's not forget that the Model 3 will be made of steel and not aluminum (body) so you have that additional weight.

    How about enlightening us about the status of the Model 3 by linking to some credible articles, just like you demand from others.

    Davewmart writes: " ... For some configurations of PHEV 4WD is virtually a freebie, as you are going to have two engines anyway. "

    One way to do this is have an electric motor #2 (EM2) connected to a clutch that then connects the motor's drive shaft to EITHER the wheels or the ICE. When the main battery is adequately charged it supplies either or both motors. When the battery is low the clutch disconnects EM2 from the wheels and connects EM2 to the ICE which then drives EM2 in generator mode to charge the battery and, possibly, also provide power for the main drive motor. In this way EM2 saves the need for an additional electrical machine (separate generator.)
