Tesla Completes World's Largest Battery Project In Half the Time Promised (engadget.com)

Rei writes: Tesla announced the completion of the world's largest battery -- a 100 MW/129 MWh wind-power backup system for 30,000 homes in South Australia. Three times more powerful than any other battery on Earth, the $50 million project had garnered press due to Elon Musk's Twitter boast that it would be completed within 100 days of the contract signing or it would be free. In the end, Tesla took it up a notch: the battery was finished 55 days from the date of contract signing and 99 days from the date of Musk's boast itself.

      I have a lot too thank Musk for, but he's far from consistent.

      Firstly it only takes a couple of "weeks" to ship from the USA in the first place. The difference between shipping from Korea vs USA to South Australia is 25 days vs 30 days (there's basic calculators you can use online for this).
      Secondly he bought the batteries from Samsung SDI not because of shipping time to Australia, but because of lack of availability from his normal supplier: Panasonic, whose batteries are made right next to South Korea anyway. The gigafactory and "made in America" was never part of the equation, and neither was shipping time.

      Any sufficiently motivated municipal electrical engineering company could have bolted all the pieces together.

      Most sufficiently motivated people can do most things. The problem is very few consider it as an option due to preconceived ideas about what a solution looks like. This entire exercise was about demonstrating the viability of a solution, not showing off that Tesla has any kind of superior engineering capabilities. This has basically been Tesla's process all along with the vast majority of their stuff actually being incredibly off the shelf, down to the type of batteries they use.

    Yeah, no one wanted his batteries so much that he was unable to fulfil the order using the existing contractual supplier (Panasonic) or from his existing factory and had to turn to Samsung SDI as an emergency second supplier.

More than Boeing and the rest of the MIC who get their own ExIm bank to loan countries with bad credit the money to buy MIC stuff? Which has gone on longer than Elon's been alive?
    Perhaps the haters can explain how the ULA drops out of bidding whenever SpaceX shows up, even though they got more subsidies for longer - and they say that they can't meet the bid price. Or how NASA crows about the huge savings they're now getting.
    Oh, we're talking about cars. So, GM got no bailout or subsidy to make my Volt?

  7. Because of black-box economics by Okian+Warrior · · Score: 5, Insightful

    Why is it any story about Musk ends up dominated by trolls and assholes? Butt-hurt much that he can actually get things done?

    Because when Tesla is viewed as a black box - considering only revenue, profit, and other information without considering the context or goal horizon - the economic forecast is very bad.

    Almost all stock predictions made today are based on this sort of black-box calculation. Every month the analysts plug a bunch of companies' numbers into their spreadsheet algorithms, and those algorithms tell them how well the stock is doing. They then write an article noting what happened in the previous month as the "reason" they say the stock is doing whatever the algorithm said.

    The analysts give the impression that they reviewed the information and are giving expert opinion. In reality, they are reporting events and claiming the algorithm outputs as their conclusion.

    Also, the algorithm goal horizon is 6 months, and Tesla has been reinvesting lots of revenue into new production (ie - gigafactory). Tesla's goal horizon is a couple of years down the road, where they will be in a position to corner the market in battery production or supercharger network or home solar.

    So a lot of people bought Tesla short, and are hoping it goes down so they can make some money. I don't know how many people are shorting Tesla right now, but 8 months ago it was something like 22% of all Tesla stock was short. Since Tesla has been doing well, that number has dropped considerably, but there are still bunches of people holding out and hoping that Tesla crashes so that they can at least mitigate their loss.

    It's a less right now, but we still hear "echoes" of all the nudging and convincing that people were doing to try to make the stock crash.

    It'll fade over time.

    You never know - maybe he was so confident of the contract that he had parts shipped before the signing, possibly he had parts already in Australia during the signing.

    As a PR move it was actually pretty good.

      Tesla uses different battery chemistry for the stationary storage units.

      Not quite. Tesla uses different battery chemistry for their stationary storage units designed specifically for daily cycling, e.g. the Powerwall which has nickel-manganese-cobalt chemistry. Additionally this battery is much safer and less likely to burn your house down due to thermal runaway. Oh but it's more expensive.

      The PowerPack (which is their grid storage solution) actually uses nickel-cobalt-aluminum, the same chemistry as their cars. This is mainly due to the load expectations being similar. The grid connected solution is not expected to be cycled on a daily basis and the chemistry favours high rates of charge and discharge which is precisely what is needed in order to stabilise a large grid, especially when the primary reason for the design is to avoid cascading failures due to a breaker opening somewhere.

      Now that being said the Powerwall used to come in two different versions, a daily and a backup model, the latter having a larger capacity and also the same nickel-cobalt-aluminum batteries as used in the cars. Not sure if that is still the case though.

      Now that ALSO being said, earlier this year Tesla's car division hired an expert who some people believe are the first step to the company shifting the Car / Powerpack chemistries to NMC as well.

      As far as I can tell that's only true if you count even non-plugin hybrids. Telsa has delivered just over 200,000 vehicles world wide, all batter electric vehicles (BEVs).

      Thought it's possible I've missed something

      Doesn't exactly seem far to call a hybrid that gets 100% of it's initial energy from it's gas engine an "electric car"; but certainly Toyota has sold more hybrids that Tesla has sold cars.

      But in BEVs Toyota is laughably behind, and even throwing in plug-in hybrids (with their vastly shorter electric-only ranges) they're look to have moved barely more than half the electric cars that Tesla has...

    I was looking at Toyota's plug-in cars and got significantly larger numbers than you did, but anyway that's a good point that Toyota's plug-in cars also have a gas engine. Maybe that's part of the reason Toyota sells a hundred times as many cars as Tesla does.

    > Telsa has delivered just over 200,000 vehicles world wide

    I see Nissan sold nearly that many fully electric Leafs last year alone, and has sold over 350,000 total. Sales numbers for BYD are harder to find, but it looks like they may have sold more than Tesla and Nissan combined. If I were betting on BEVs being the future, Nissan, BYD, or even Renault seem more likely to become the world's largest car maker than Tesla does - both Nissan and Renault have the dealer and service infrastructure and everything that Tesla lacks. Make no mistake, the current pricing of Tesla's stock assumes they'll be the world's biggest car maker within a few years.
