    The promising new technologies are: Compressed air in caverns, molten salt, and Li-Ion batteries.

    Compressed air seems to be more economical than batteries today. Utilities would prefer this because, we would still need the grid.

    Molten salt idea is to melt common salt using solar energy and keep it in underground tanks, and boil water off the stored energy to run steam turbines when the sun is not shining and the wind is not blowing. It involves basic thermodynamics and heat to mechanical energy conversion. So its efficiency is not great. It might come back to bite. Again utilities like this because we would still need the grid.

    The Li-Ion battery prices are following a 7 year half life curve. We are at the cusp 100 $/kWh at pack level magic number right now. Tesla claims it is at 120$/kWh at pack level and below 100$/kWh in cell level. Others are close or ahead. Even at this price, batteries can stabilize the grid and take care of sudden changes in wind or solar generation. It has already saved Southern Australian grid several million dollars in the spot market for electricity. And with some financial engineering and capitalization of revenue streams, solar panel companies are viable in many places where the utility prices are high. At around 80$/kWh at pack level most middle class homes will be able to choose the grid or panel+batteries for their home. As prices drop below that level, affluent people will start dropping off the grid, (like affluent commuters dropped off public transportation in the 1960s and bus/tram lines collapsed in 1970s). This is the scary situation for the electric utility companies. Cost for remaining customers go up, and more people drop off the grid. When will the batteries be at 65$/kWh at pack level? If Elon Musk's secret master plan is right, it is just 7 Elon years from now. Like N Dog years = 7*N human years, N Elon years = N+6 human years. So we are looking at 2031 for this price for batteries.

  4. The setting was an isolated island in the Pacific in the 15th and 16th century. Among the vast selection of brutal savages with technology, the one that is likely to see the smoke signal would be some like Vasco da Gama.

  5. No, not Vikings. Vikings took bath regularly. More like medieval Anglo Saxon savages who thought taking a bath or cleaning them would make them lose their strength in battle. 500 years before the development of the Germ Theory of Disease they had stumbled on to the secret of biological warfare.

  6. Imagine some primitive stone age tribe living in some island in the Pacific. Never knew if they were alone on the Earth or some other humans existed elsewhere. Some Chief gets the bright idea to send smoke signals so that if there are people somewhere in the ocean they will know there are people on this island.

    Any tribe that had such an idea in the 15th and 16th century would have been run over and destroyed before they even know what was happening.

    Why would you assume the aliens will be any less brutal than the 16th century European explorers?

  10. The Wall St Journal report Elon is critical of, came right in the middle of a huge rally last week. Big positive earning surprise, and that Friday when options close and sort out, the report came stopped the rally. Then within an hour the market realized it is old news and it recovered.

    The second report about subpoena came yesterday during market hours. Again it seems to be recycling some 10-K filing done in September. This time market did not budge much.

    The S3 partners is reporting that the number of Tesla shorted shares has come down a little. But because of the price increase the value of shorted shares spiked making Tesla most shorted shares again for a while. S3 does not think the shorts have been squeezed, and there is no forced covering of shorts. The big players are ignoring the paper loss, and girding down for a longer fight.

    There was a shortage of shares that could be borrowed, down to almost a few thousand shares and the cost of keeping a short position open was seven times more expensive for TSLA shorts than other securities a while back. S3 says it has eased now and 16 to 20 million shares are now available for borrowing. So the cost of keeping the short position open for another quarter is not much for the big ones.

    Some long time shorts are exiting. A second one (not the Left of Citron, another one) announced "Tesla short is no longer the bankruptcy live or die short thesis. It is now merely a valuation too high short thesis. So I am out".

    Soon "Tesla is going to die" stories will stop generating clicks and these click-bait "journalists" also will go away.

    This is my theory, which is quite mild compared to most fanboi conspiracy theories: The timing of WSJ stories suggest it is well connected small time shorts with good connections, who ride along the big players, who are "persuading" friendly journalists to plant stories so that they can exit.

    Were they merely overly optimistic then or were criminally misleading? Since almost all the production woes were quite public. Tesla has said many times it was betting the company. Its behavior in early 2018 can actually shows it was just overly optimistic.

  16. It's worth nothing that the rats were exposed to radiation at a frequency of 900 megahertz, the frequency used in the second generation of cellphones that prevailed in the 90s, when the study was first conceived. For comparison, fourth generation (4G) and fifth generation (5G) phones employ much higher frequencies, which are "far less successful at penetrating the bodies of humans and rats," the NYT reports.

    Study originated before 2000. They spent 30 million dollars. Studied 900 MHz phones. Now we are using the 5 GHz bands. So they need 150 million dollars, (five times higher frequency, they need fives times more funding) and another 18 years to study the link between new phones and rat cancer.

    They might need another 30 million dollars to study if the rats were "holding the phone right", if they were using iPhones

    Microsoft is fighting back with its best product. VisualStudio. When it comes to Integrated Development Environment, there is nothing better than Visual Studio. Already Microsoft is supporting ssh daemon and incoming ssh connections, linux tools are shipping with WinX.

    Visual Studio is attaching to gdb and xdb command line debuggers in Linux from Windows in Visual Studio 2017. I would not be surprised if Windows become the preferred development platform for Linux clients also. Given Active Directory has managed to get a strangle hold on authentication servers it is making serious efforts to displace many unix tool vendors.

    If Visual Studio painlessly steps through code running in a linux machine with the GUI running on a windows box it will get lots of sales there.

    MS might lose the numbers game, but in some sense it already has. iPad and phones have become the most common computers, lap top sales are dwindling, desktops too. So in some sense latops and desktops are losing to phones and pads.
