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.

  1. Those are definitely the things that happened by Anonymous Coward · · Score: 5, Insightful

    The man said he would do the thing, and he did the thing.

  2. I'm actually impressed by Baron_Yam · · Score: 5, Interesting

    I assumed when he made the boast that it would be 100 days from the signing of a contract, or that there'd be an allowance for shipping times to Australia and possibly other 'fudge factors'.

    I'm now assuming instead that there was a huge loss involved here in order to move and install the required hardware in such a short time, just to prove the point it was possible and would actually work, and thus make future sales more likely.

  3. 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.

  4. Re:Musk completes largest tax drain on Earth by HanzoSpam · · Score: 5, Insightful

    Ok, I'll give you that Musk is a tax soak. But unlike most tax soaks, he actually delivers some cool and useful things for the taxpayers dime. In this case, I'm willing to look the other way. When it comes to cutting waste of taxpayer funds, there are a lot of other candidates I'd cut before I got around to Musk.
