    So if Bill and Melinda Gates were smart they would have about $8,000,000,000 in bonds/CDs/money market/checking/savings.
    And if Warren Buffet bonds/CDs/money market/checking/savings was smart he would have $6,000,000,000 in bonds/CDs/money market/checking/savings.
    So if Larry Ellison were smart he would have $4,600,000,000 in bonds/CDs/money market/checking/savings.
    Maybe Elon Musk should invest the almost $1,000,000,000 he has in bonds/CDs/money market/checking/savings into the gigafactory ...

    There. FIXED.

    So Bill and Melinda Gates have about $8,000,000,000 in cash lying around.

    And Warren Buffet has $6,000,000,000 lying around.

    Larry Ellison has $4,600,000,000 lying around.

    Maybe Elon Musk should invest the almost $1,000,000,000 he has lying around into the gigafactory ... but he can't :-(

    They must have really big mattresses.

  • Tesla Motors: China Update [View article]
    molli & doubleE:
    The batteries for which $44,000+ was charged were probably not degraded but damaged in some way that did not satisfy the warranty requirements. I shouldn't have brought those up in the current context.

    However, even when an owner was unaware, some batteries were replaced under warranty when the car was brought in for some reason. Whether the problem was some bad cells, or damaged internal connections, or whatever, the fact that the batteries were replaced means that they were, as far as the owner was concerned, totally degraded. There is some evidence that replacement batteries may not be new but factory refurbished.

    Really? Are you sure?
    In well documented instances, several Model S owners were charged over $44,000 for replacement 85 kWh batteries (before the latest warranty upgrade.) In addition, numerous owners have had their 85 kWh batteries replaced under warranty when brought in for service.

    Toastypro writes: " ... it does not need 58KW generator, it may work with a smaller one in range of 4KW-8KW to provide charging for several hours while driving."

    You do know that you can't charge the battery at the same time you're also discharging the battery to provide power to drive the car? To charge while driving would require a second battery to drive the car and then switch between the two as required; what a wasteful design concept.
    On the other hand, if you did have the 58 KW generator (you discarded) , you could use it to power the car under nominal conditions (about 20 - 30 kW) and still have plenty left over to charge the battery, which is no longer powering the drive motor. There is ample power left in the 58 kW ICE to handle modest changes in immediate driving requirements and if you suddenly need lots of power, you kick in the battery for that; sort of reverse of the process of regenerative braking. You would mostly engage the ICE when needed for drives exceeding the battery's range capacity. The ICE as a supercharger on the go also offers many other desirable options and capabilities.

    mjrickard writes: " ... Average time at the gas station: 17 minutes and 20 seconds. "
    Jack Rickard spends perhaps an hour, or so, timing how long it takes to get in and out of a gas station and comes up with an average of 17 minutes and a minimum of 11 minutes.
    Some other commenters here come up with 24 minutes and other atrocious times.
    Yet, in the battery swapping video of 2013, Elon Musk himself times a huge SUV loading up with 23 gallons of gas in 4 minutes 10 seconds and this includes about 30 seconds for credit card swiping. Most cars don't load 23 galllons; mine is 17 max, many others 15, and some much less than that. Using the data gathered by Elon Musk himself, it should take me no more than about 4 minutes to fill up a reasonable car's gas tank. Another measure is that I fill up at a rate of 80 miles per minute ( I get at least 350 miles on a tank full); the 20 minute Super charge to 150 miles is a rate of less than 8 miles per minute.

Musk makes the trip from northern to southern CA weekly and my guess is he WILL use the swap station as will others of his officers and likely this will attract more CEO's who have to make the trip - think about it, to fly - 2-3 hours to get to the airport, 45 minute flight, hassles at the arrival end and then the reverse - Tesla Model S - 5 hour drive (LA to San Jose), converse (work) while driving - Elon plans for the most productivity for himself and other and the battery swap may be self deserving but will also help drive the technology - "

    Wow. Just Wow.
    You think that Musk spends 10 hours a week driving back and forth between Northern and Southern California? Other CEOs do the same? For Musk to waste that much company time is a crime against his companies and company investors. Doesn't he have a corporate jet for that purpose - so he doesn't waste 2-3 hours to get to the airport (WHAT - no closer airport?) and on and off a commercial plane. And if he doesn't use a corporate jet, then he is wasting company time and resources. Shouldn't he, at least, have a driver for safety and so that he can work?

    Keep coming up with these self serving scenarios?

    Yeah, with a typical car roof you might be able to get about a miles worth of energy for every hour of sunlight ... if you have the very best solar cells and system.

    Tech Talker writes: "Its called an adapter"

    Yeah, but the Tesla will take 3 or 4 times as long to fill the battery to the same level of charge. I don't think others waiting in line for a charge will be too tolerant of "charge hogs."

    Battery swapping is a really bad idea.
    First, you have to do at least two swaps to get your original battery back; that's 2x$60, at the very least. Secondly, if you go a long distance it's swaps every few hundred miles. Even if the swapped batteries are rotated within the system, you still have to get back to the original station to get yours back; or it's $thousands for that swapped battery. And if you thing the supercharger network confines you to certain routes, the swapping network will be even more restrictive. Each swapping station will have to have a pretty complicated and expensive machine and attendant to perform the swap and many charged batteries stored for anticipated customers. No more simple "pump" in a parking space; now they'll need an actual structure and space. And liability if the battery (whose battery?) does something bad.
    The down side to this battery swapping is just too great to enumerate here. It's just a bad idea.

    Do you get a new gas tank with every fill up?

  • Tesla's New $120,000 Flagship Matches The $61,000 Dodge [View article]
    John Bingham writes: " ... Even at that retail price (and both the cost and the capacity of such batteries will improve in the future) you're talking about at least 170 MWh of throughput over the lifetime of the battery in the car, not just 85 kWh. "

    Well, that 170 MWh represents 2000 full charge/recharge cycles at a cost of $22 per cycle, paid in advance by as much as, say, ten years. In addition, the full charge cost of 85 kWh is at least $8.50, giving a full cycle cost of more than $30 to be able to travel 265 miles. An ICE can be expected to require 10-12 gallons of gas to do that and at $3.50 per gallon that comes to $35 to $42; paid as you go and not in advance. So the saving of $5 -$12 per cycle, while meaningful, is not nearly the windfall that you would have us believe.

    " ... And as the battery may be repurposed for stationary storage after that time there could even be a good trade-in value if you decide to buy a new, longer range pack to replace it. "
    This "repurposing" has yet to be demonstrated as economically useful. The viability of a 10 year old pack has to be questioned because its possibility of failure is certain to be high and the installation/reinstall... effort and cost of replacing that "old" battery after a few years also high in comparison to a new battery and full warranty (including labor.) The Tesla 85 kWh pack would need work (re-plumbing, modified operating voltage) to be suitable for stationary applications; you can't just take a chainsaw to cut it in half, or thirds, or quarters, or etc.

    Advantages of going "electrical" are real; I know, I've been an electrical guy for over 50 years. But the uncontrolled hoopla exhibited by some (not you) is embarrassing and does more harm than good.
