  1. Tesla death watch, sneak post view on Elon Musk Continues To Amuse Himself On Twitter, Sharing Song, Duck Emoji (billboard.com) · · Score: 4, Interesting

    Meanwhile the fans are planning a Eleventh Tesla Death Anniversary Celebration. The link has all the previous predictions of death of tesla. Interesting chronology.

  2. Q1: Demand. Q2 gross margins. on Elon Musk Continues To Amuse Himself On Twitter, Sharing Song, Duck Emoji (billboard.com) · · Score: 1
    The most interesting things to watch out for in the initial production/delivery numbers expected tomorrow or day after are Demand, and Gross margins.

    It is very clear the pent up demand of people who booked years ago willing to buy higher trims have been fully sated. By 19Q2 around the world all people willing to pay high priced versions would have bought them. Going forward it needs to sell the lower priced versions to generate the cash it needs to develop the truck and bring to production the Y, the semi and the roadster2.

    Is there enough demand for the 35K version? Are there enough gross margins to pay down the debt and pay for new facilities? Indications are they definitely have a positive margin on the low end version. It is marginal or is it substantial in the 15% to 20% range? That is the question.

  3. Not sure what this really means on Elon Musk Continues To Amuse Himself On Twitter, Sharing Song, Duck Emoji (billboard.com) · · Score: 2, Informative
    This quarter 19Q1 does not seem to be as critical as the 18Q2 where the cash position turned very precarious. This quarter had unexpectedly long delays in getting euro transition and certiticates, Some China deliveries. Guidance changed from "profitable in all following quarters" (18Q4) to "small loss" (Jan 2019) to "definite loss" (Feb 2019). Share prices are reacting to that.

    SEC contempt case is not strong. "Must pre screen all tweets" was the original demand, it was redlined and negotiated and taken out. So it is clear Tesla never agreed to pre screen ALL tweets. SEC seems to be under the impression there should be a standing panel with some board members and appointees to screen the tweets. Tesla seems to be thinking, if Elon agrees not to treat anything material, not tweet anything during trading hours, there is no need to pre screen, just a post screen to issue clarification before trading resumes.

    The particular tweet seems to be very immaterial, not much to hang its coat on. If this is the most material breach they have found, SEC has nothing. Looks like it is just a pretext to show that there is no standing panel, no real process to pre screen tweets. Court can rule for either party, but not likely to punish Tesla much. Elon has not made a market moving tweet since funding secured. So SEC got what it wanted.

    Usually wont reply to AC. But to rebut the FUD.

    The link I posted is from bloomberg, not some wild eyed greenie tree hugging site. They calculated load cycle, investment cost, repayment interest, amortization and life of the batteries into the calculations.

    Tesla batteries have been absorbing at the rate of 128 kW for several years now, discharging to a surging peak of 400 kW routinely. And you still FUD on chemistry.

    NG is a sort of battery? Yeah, sure solar energy from millions of years ago were stored in the natural gas and is being discharged now. Once you deplete it, just wait for a few hundred million years for it to "recharge". Dimwitted beyond belief!

    Coal to natural gas conversion is very cheap and natural. So as soon as the gas prices fell below coal per megajoule they switched to gas. Easier to transport, adding a bunch of nozzles to an existing coal fired furnace is trivial, without ash removal issues it is so much simpler.

    So natural gas will kill coal very quickly. Solar will kill natural gas slowly.

    Natural gas is cleaner than coal. Thats about it. Megajoule per megajoule it emits same amount of CO2 as coal.

    In CA PG&L is closing three natural gas plants replacing them with batteries. Four systems, two experimental at 10 GWh each. Two large systems 350 MW x 4 hours and 175 MW x 4 hours.

    South Australian grid using wind mills widely separated was the first one to go in with a 50 MW system. It stabilized the grid and flattened the spot market prices so much they saved millions of dollars. Every dollar saved by the utility is a dollar NOT EARNED by gas powered plants. The ROI on natural gas plants are going to take a serious rework, they are losing juicy profits in the spot markets.

    Now, Florida. Cost of storage batteries is falling so rapidly, it is like the micro chip revolution in computing. There is a Moore's Law for batteries, with a time period of about 7 years.

    The neck of the famous "duck curve" is after sunset in CA. Solar has stopped, but a/c load is yet to peak. That one hour after sunset is the last critical piece needed for solar to become totally effective against natural gas. It is at hand. It is very exciting for the renewable energy fans.

    Some of the gas plants operating in the peak load are "quick response" gas turbine plants. Their quick response is still measured in tens of minutes. The batteries are responding in milliseconds. The key thing about spot market electricity is, the price can go negative. If the gas plant is producing power and the grid could not absorb it they need to pay someone to take their power. The gas plant will not throttle down for several minutes. Who can absorb that power and get paid? The Batteries! Once the battery systems reach a critical mass, all natural gas fired power will be sold at long term pre negotiated fixed contract prices. Not the spot market. This will seriously change the ROI calculations of these plants that were already built. I am expecting the owners of these plants to cry uncle and come with hat in hand asking for "relief" from the utility rate payers.

    Should not be a serious problem. They were able recover data because it was unencrypted. Tesla should be able to encrypt the HDD and SSD .

    Even simple symmetric XOR encryption is enough, if the key is individualized for each car. Unless the computer is still operational and you are able to step through and find the key in memory you can't hack it. And it is not that hard to do public-private keys too.

    How to protect decryption when the car is totaled but the computer is still functional? That would be hard, but it should possible to remove/destroy one chip somewhere that holds the keys. And issue guidance to insurance companies and users to destroy that part when the car is totaled.

    We were freshman in IIT, having passed JEE, head high in the clouds, top 1000 All India Rank, all the orientation speakers calling us creme-de-la-creme of India. First Chemistry 101 class. Reading ahead for the class, our study group found there are some electron orbital stuff, n orbital, p orbital etc. One of them was described to be doughnut shaped. All of us were stumped. We did not know what a doughnut was or what it would look like.

    Then one from our study group found an American chemistry text book with pictures. It spelled doughnut as donut, but had a picture. We exclaimed, "It is a damned torus! Why wouldn't they call it a torus? Why use this weird thing donut/doughnut". In the class Prof PJ Narayanan said, "... it says doughnut in the text book. Doughnut is like a vada but it is sweet not savoury, they make in the West..."

    If slashdot is going to call itself "news for the nerds" the least it can do is to call that shape by its proper name, a torus.

    Do you know how much work there is shutting down the coal mines safely? All those tilings left behind. Mine shafts to be systematically closed and sealed, lest some random soccer team gets lost in there. All those toxic ponds of pumped water to be safely disposed off. These are all green jobs. The coal companies posted bonds to do the clean up. Or have self bonded. There are just 50,000 coal workers left. And we need them. They are the only ones skilled enough, trained enough to do the job. None of the coal workers want their kids to get into coal mining. They really don't want the coal mines to operate in perpetuity. All they want is a honest job with honest pay till their retirement.

    Orderly shutting down of coal mines would do the job, has the money for it. But you can trust Republicans to play up the emotions, steal all the bond money posted by the coal companies and leave the workers high and dry, and the taxpayers with the clean up bill.

    If the coal workers have any sense, they will support the Democrats and make sure they get the job of safely shutting down coal mines. There is enough work there to guarantee jobs for the coal workers till they retire. There is money for it from the bonds posted by the coal companies. Democrats will make sure those bonds are actually used to give jobs to the coal workers. If they go with the Republicans, the companies will self post, sign some papers, steal the bonds, and promptly declare bankruptcy after divvying up the money.
