    The times they are a changing.

    Modern power electronics can do DC-DC conversions efficiently. High voltage DC power grids with significant advantages are arriving:

    Dave_M writes: " ... Tesla was trying to promote a superior "Alternating Current power grid", while Edison was promoting an inferior "DC power grid". "

    How ironic that Powerwall is a 350 - 450 V DC device and that superchargers deliver DC power to Tesla cars. Today major power grids are designed and built to operate at 500,000 V, 750,000 V and over 1,000,000 V using DC rather than AC; it is more efficient and cost effective to transmit DC current over long power lines because the wires can be significantly smaller and lighter.
    Incidentally, the AC/DC war wasn't so much a clash between Tesla and Edison, as it was a clash between Westinghouse and Edison; Westinghouse was a great inventor, innovator, and industrialist who seems to now be forgotten.
    None of my comments are intended to take anything away from the great genius of Tesla, but it was Westinghouse's money and foresight (much like Musk's) that helped fuel early electrical progress in the US.

    Equally miraculous in 1969 were the underdog Jets and Broadway Joe defeating the unbeatable Colts, even with Johnny U making a late appearance.

    There are several claims: " ... that Panasonic, Tesla’s major partner in the Gigafactory project, will involve 14 more companies at the Reno location. "

    I think a Sushi restaurant may be one of them.

    Ahh! I bet a friend that the Mets would win in four straight. Horror of horrors, the Orioles won the first game and I was sunk. Then the Mets won the next four in a row to take the series. So, did I win the bet?

    watchingfromabove writes: " ... LOL! The idea for SC isn't to drive from home and fill up and go back home. Nobody in their right mind would do that. You fill up at home and if your plan is to visit grandma, you drive to grandma and fill up at the SC enroute. "

    Of course I'm not talking about using a SC instead of the charger at home. I'm talking about a business trip, scenic vacation, or other trip where you go off the Tesla favored route and have to be careful not to wander too far from an SC. And if you try to top off before a side excursion, it takes almost twice as long (as expected) to "refuel" because the battery is near full. This is not as uncommon as some would like to believe.

    " ... you drive to grandma and fill up at the SC enroute. " But, but, what if there is no SC enroute? What if there is no charger at grandmas? In the Baltimore/Pittsburgh route I mentioned an SC in not conveniently located and for the return I would have to go miles, and at least an hour, out of the way.

    An example is this Tesla owner who probably has to take a cab to his Model S:

    AntiBodian writes “ Why?? “ then follows with a description of superior Tesla functionality. I’ll get back to that shortly,

    To start, I apologize for not responding sooner (from 4 days ago.) But, since it wasn’t addressed to Zelaza, I didn’t notice it and I wouldn’t want AntiB to think that I was ducking him (as he has accused me in the past.)

    Getting back to supposed “Tesla functionality”. I have taken my first serious look at the Supercharger map and find its promises hollow. The claim, and map demonstration, that about 98% of the population is within 100 miles of a Supercharger may be true but is totally meaningless. Imagine being 50 miles from the nearest SC, let alone 100 miles, and having to drive there and back, spending 4 hours (100 miles back and forth) and ending with hardly any additional range on the meter. Ridiculous. The Supercharger map of reachable “domain” is Tesla Deceptive and, instead, should be limited (at best) to 20 miles and more realistically to 10 miles (from Supercharger) before proclaiming how much of the population, and land, is covered. For me, trips I normally take would be terribly inconvenienced (including Baltimore to Pittsburgh via the beautiful and scenic route 68 and Laurel Highlands.)
    Another flaw I find in the Supercharger map is that it doesn’t specify the source of electrical energy for each Supercharger. Since green energy is one of the main justifications for the Tesla EV, one would think that each Supercharger location would specify where its energy comes from: whether hydro, nuclear, natural gas, coal, wind, PV, other.
    So, it is true that currently Tesla has more functionality than other EVs, but only if you don’t get too far from the Tesla selected route.

    AntiBodian also writes: “ … And sorry about that G35X. When you grow up perhaps you'll own a nice car. “
    Talk about immature and someone’s need to grow up! Actually, I really love my G35X. It bothers me that it sucks gas, but that’s a price I’ve accepted. My 8-9 year old G35x is great. I bought it used and paid well under $30K. It has all the options including adaptive cruise control (it’s a 2007), voice commands, headlights that track in the direction I'm turning, and etc. It’s very comfortable and a pleasure to drive. I don’t need to go 0-60 in 5 seconds or less, nor pay outrageously for that feature. The most serious problem I’ve had, and that caused the dealer to hold my car for several days, was to replace the CD player at no cost to me (they wouldn’t let me have the car back until they got a replacement player.) Of course, they let me drive a Q50 which had all the bells and whistles and proximity sensors and safety stuff.
    Anti, since you’re so keen on driving between St. Louis and Denver, would you “race” me in my G35x? Although I’ve never been on any such route, I’d let you pick a Tesla friendly route and even give you a two to three hour head start: my $30K old car vs fairly new $90K+ car.

    Well, Tesla charges $39.5833/month for a four year service plan that allows a single inspection per year. Doesn't this seem excessive for a car that is supposed to be almost maintenance free?

    AntiBodian writes: " ... And feel free to tell me how you'll get that Bolt from Denver to St. Louis. I notice you keep avoiding answering that question. It doesn't have to be my way. Show me your way. "

    I'm not avoiding the question. It is a vacuous question for me because I have no interest in getting a Bolt, Leaf, or other BEV because they don't meet my needs. But I can easily get from Denver to St. Louis by using my 2007 Infiniti G35x. If I start with a full tank of gas, I can do the trip with one stop of 5 to 10 minutes. Or, if years ago, I could use my 64 1/2 Mustang Convertible, or my 1975 280Z, 1983 300ZX, 1997 Acura 3CL, or my 2003 Infiniti G35X. For any of these cars the question of being able do the trip would never come up. And I could make side trips to interesting and out of the way locals. For the same trip I figure you would have to make at least three "refueling" stops of at least 1 hour each. If I had a garage I might consider a Volt like EV with which I could do 90% of my traveling purely electrically and not ever be concerned about long trips.

    " ... Enjoy your Bolt and the very small radius in which you'll be able to use it. "
    This reveals to me that you are one of those that only pretend to favor EVs while actually only supporting Tesla. If you're into EVs, why do you hate on GM or any other car maker that intends to build EVs? Why???

    Davewmart writes: " ... I think in-wheel motors likely for the Model 3."

    I couldn't disagree more.
    Assuming only two motors for either the front wheels or rear wheels, the necessary torque per driven wheel would be five times that of the current motors because the (almost) 10:1 gearing advantage would not be there. Five times the torque implies five times the current draw per motor; very unreasonable for intended demographic. And then there is the issue of unsprung wheels, a driver/inverter per wheel, plus other headaches to contend with. And four in-wheel motors just amplifies the difficulties.
    I think the car will use the smaller of the two motors in the dual drive Tesla because it seems to have a very respectable torque and horsepower capability for the intended car (or my perception of it.)

    Maybe the Model 3 will look like one of the tear drop shaped bicycle racing helmets. After all, I seem to recall Musk commenting that the Model 3 shape will be unconventional (or some such phrase.)

    AntiBodian writes: " ... And unless the GM dealers are putting in multiple DC fast chargers, you're likely to get blocked ... yada, yada, yada,..."

    Anti, you have a very narrow view of how other people will, or can, do things. Teslarians often accuse those who question some Tesla practices or goals as being narrow minded, unable to see ahead, stuck in their ways, etc., etc., etc ... in short, luddites. When it comes to how GM, or any other big manufacturer, will deal with long distance travel you are the one thinking like a luddite because you assume that they will try to do things only in your narrowly imagined way.
    How many gas stations were on the Oregon Trail? Not many because there was no need for them. In the same way, the big car manufacturers haven't populated the landscape with superchargers because they have no need for them, yet. (Incidentally, I consider a charger a supercharger if it operates at about 1C.) When they do, and there is a shakeout of what battery sizes and types make sense, you can be sure that appropriate chargers will be available everywhere and in very little time. Tesla's network cost about $150 million (I think ... whatever ...) and this is a pittance to a consortium of car makers; a suitable system can be up and running in no time.
    In my high school electronics courses, half wave, full wave, and bridge vacuum tube rectifiers were the first things we learned to design ... and making them regulated didn't require much more ... (loved those surplus military vacuum tubes and parts available on Canal Street.) Chargers are some of the most straight forward devices to produce ... ain't no magic required.

    " ... Once you've done that, I'll provide the same plan for a presumptive Model III assuming it's exactly the same as a Bolt except with supercharging. My plan will include actual locations and what's available nearby. Get to work! "

    So you plan a military style logistical effort for a trip. I don't. I would use a hybrid which would be all electric about 90% of the time I own it, and heat engine powered a fraction of the remaining 10% including the "trip." See, I'm not restricted to your rules. Incidentally, if you start in about two years from now, and with little planning, you can walk from the East coast to Silicon Valley long before your Tesla Model 3 gets you there.
    Buy the whey, a little less intensity and insults would serve you better.
