  1. Sour grapes of the short sellers? on The Billionaire Space Race Is Making Life Difficult for Airlines (bloomberg.com) · · Score: 1
    Short sellers have borrowed and sold 39 million shares of TSLA, 30% of float. Or 23% of total stock. They have pledged 12.5 billion dollars of other securities as collateral to hold this position, and they are paying 2 million dollars a day to sustain the position, as fees/interest for the borrowed shares. They have already suffered 2 billion dollars mark to market losses in the recent surge to 370+.

    Elon has been taunting and teasing them, "Tsunami of hurt coming their way ..." "In three weeks their position is going to explode ..." "They are going to get a rude awakening ...". It is coming to a head, tomorrow is a short settlement date and next week Q2 numbers are going to be released. Meanwhile AWD models are announced, and price has been dropped, and people are configuring AWD, performance options, white interior etc etc.

    Goldman Sachs had been whispering it is going to miss the production numbers, now it is saying "even if it meets the production number it does not mean much".

    The shorts are painting the picture of wild eyed liberal tree huggers enamoured by con man who is making cars in a tent, burning cash, losing money in every car sold, and trying to make it up in volume. But 85% of the float is owned by institutions, that is 60% of the total, that is 100 million shares valued at 30 billion dollars. It does not compute these seasoned mutual funds and investment managers would risk their return "to save the world". Shorts are still have not started covering their position. So we will know end of next week, how it all ends.

    Either shorts are right, stock crashes to 100$, SpaceX buys Tesla and takes it private.

    Or they are wrong, and the stock hits 500$, and so many hedge funds go bankrupt we actually learn the names of the people behind the shorting.

    Anyway it sounds more like sour grapes story spun up by the shorts.

  6. Right angled triangle != Pythagoras Theorem. on Stonehenge Builders Used Pythagoras' Theorem 2,000 Years Before He Was Born (techtimes.com) · · Score: 5, Informative
    The link sheds no light. But lots of ancient cultures knew right angled triangles. That does not mean they knew Pythagoras theorem as we know it today.

    I know an ancient Tamil formula that seems to be Pythagoras theorem at the first glance. "Make eight parts of the running length, and discard one part, add to it, half of the altitude. What you get is the hypotenuse". Instantly one notes, there is no quadratic term. It is a linear formula, so it is not a general Pythagoras theorem. It boils down to "when two sides of a right angled triangle is 4 and 3, the hypotenuse is 5".

    Nothing unusual. All they needed was an easy way to construct the right angle. That is all. The simplest way is the make a lasso with a rope ten units long, and mark off 3 feet and 4 feet, you can form a right angled triangle. If you make the rope hundreds of feet long, the angle will be accurate enough for the ancient construction techniques.

    Egyptians had been using the 3-4-5 right angled triangles to demarcate land holdings after Nile floodings 1500 years before Pythagoras.

    For aligning ancient temples, pyramids and other structures with East/West directions, the technique was ridiculously simple. Plant a pole, and mark the tip's shadow location at sunrise on equinox day and again the location at sunset. Line joining these two points is East-West. Use the 3-4-5 triangle from a 10 unit long loop of a rope and mark off North and South. Use plumb bob for vertical. You have a clean three axes Cartesian coordinate axes marked on the ground.

    Dont get me wrong. I am amazed they can identify the equinox and solstice days, that they can predict eclipses, form calendars, They were as intelligent and smart as any modern human being. 5000 years is, but a blink of an eye, in evolutionary time scale. But let us also note that what we mean by Pythogoras theorem today is vastly different what they were using back then.

  8. Shareholders fined. on Volkswagen Fined One Billion Euros By German Prosecutors Over Emissions Cheating (reuters.com) · · Score: 3, Insightful
    The money will come from the current shareholders of VW.

    The perps are in their mansions, not in jail.

    The perps are not going to pay the fine. There is no clawback provision to get back the bonuses and salaries and incentives they got for achieving the goals by cheating.

    The shareholders should sue the board and ask them to pay the fine without using company funds.

    Board might sue the old office holders and get the money from them.

    But none of that will happen. So next scandal will happen. There is no effective way to punish the Criminal Executive Officers.

  16. The containers are still being loaded and unloaded using gantry cranes. The railroads should design very low floor flat bed cars. Containers should have a small batter and wheels to "self" drive and get off the road tractor trailer frames and get on to railroad cars and vice versa. The battery should have some small range, like 1 mile at 10 mph.

    The long distance freight trains should pull into a yard close to a major highway intersection like I-75 on I-80. A whole bunch of containers get off on one side, another bunch gets on from the other side and the train pulls off in 15 minutes, next stop could be I-65 on I-80. These containers follow dedicated path to freight sorting centers while they are being unloaded sorted and reloaded. The container traction batteries can be recharged by the train or the loading center.

    But even such an efficient system would not be able to beat a fully electric truck as envisaged by Tesla. Already Tesla is reporting battery cell prices below 100 $/kWh. Pack price is expected to be 130 $/kWh. Trucks with a two battery system can be designed. One permanent battery to keep the truck mobile, and a range extender swappable battery pack that is typically rented on the highways. It is just the battery pack price that is the stumbling block. Running cost of electric vehicles is about 1/5 of diesel trucks. The steam to diesel transition was quite slow between 1930 and 1938. But between 1938 and 1948 the bottom just fell out of steam loco markets. And the running cost differential was just 2. (Diesels had 15% thermal efficiency back then. Steam was at 6%. But coal was cheaper per BTU. The net was a factor of 2). Compare this to Tesla Model 3 costing 3 cents a mile charged off the grid (12 cents /kWh, 4 miles/kWh), compared to 15 cents a mile for similar gasoline car (3 $/gallon, 20 MPG). It is a factor 5. The transition would be even faster, if the initial investment cost is brought down to affordable levels.

    By making the range-extender battery rentable, the truck operator will just compare the cost per mile, battery price financing gets folded into energy price.

  21. The energy "content" is 10 times that of electro chemical batteries. OK, go on.

    Half life is 100 years.

    So, half, that is 5 times the chemical batteries is available over 100 years. Right?

    So, on average, 1/20 of the energy is available per year .

    That works out to 1/7300 per day. But the decay is exponential, so we need a correction from mean to peak. Let us be generous and round up e (=2.7182818) to 3. So you are looking at 1/2500 of chemical battery energy per day. Divide by another 86400 to get per second. That is the max power out put of this device. Looks like you would be better off harvesting the power from local WiFi signals.

The shortest possible braking distance is decided by the tire not by brakes. That is the meaning of "limited by the tire, not by the brakes".
