Consequences / Re: COVID-19

"There is no scientific evidence that meat transmits the virus."
But, “the coronavirus can survive freezing temperatures and still be active when thawed.”

Chicken wings test positive for Covid-19 in China, but there's no evidence of food transmission, experts say
A sample of frozen chicken wings imported from Brazil has tested positive for the novel coronavirus in the southern Chinese city of Shenzhen, authorities said Thursday, the latest in a series of reports of contaminated imported food products.

The coronavirus was detected Wednesday on a surface sample taken from a batch of chicken wings during screening of imported frozen food in Longgang district of Shenzhen, the municipal government said in a statement. Officials did not name the brand.

Health authorities, including the World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC), have said the possibility of catching the virus through food is low.

David Hui Shu-cheong, a respiratory medicine expert at the Chinese University of Hong Kong, said the imported food products that tested positive in China were almost certain to have been contaminated during packaging.

But he said it doesn't necessarily mean that they're infectious -- the nucleic acid tests could be picking up the RNA of dead virus. These remnants of the virus are known to have caused false positive results on patients who have recovered from the coronavirus, such as in South Korea.

If the virus taken from the food products can be grown in labs, however, then they are infectious, he said, adding that the coronavirus can survive freezing temperatures and still be active when thawed. ...

In many ways it is not even worth talking about these stats.  The Zoe factory has a capacity per year that will be exceeded by Tesla in 1q within 6 months.  The Zoe has sold 300k vehicles in Europe, ever! The eGolf is not the VW main EV and the stats mask the Id.3 catastrophe.

Giga Berlin will produce 500k vehicles per year by end 21 and a total capacity of 2m vehicles.

This kind of news will have a very short shelf life but nobody will go back and call it out for what it was 6 months from now.

That is the whole problem.  If the purveyor of this "news" was ridiculed constantly for the next 6 months they might actually be a bit more careful with how they present their "truth" next time.

Being that the article was German-centric, it is likely it was written that way to comfort those with a stake in the German auto industry, who are desperate to hear anything that suggests that Tesla is failing, especially on German turf.  Legacy companies will continue to insist that despite their ICE burden, they can successfully make the transition to EVs... somehow... up until their own factories shut down.

The single piece casting machine for Model Y has been installed in Fremont. Shanghai and Berlin will also use single piece casting.

Elon Musk (@elonmusk) 8/13/20, 10:51 AM
Will be amazing to see it in operation! Biggest casting machine ever made. Will make rear body in a single piece, including crash rails.

< a rear-end collision will require replacing half of the car (if it's all one piece)?
Quantum Tarantino: No. The rear end of the car is two pieces. One smaller piece sits on a crash rail. In the event of a crash the smaller piece crumples into the crash rail. If it's a massive rear end collision then the car would be totalled anyway.

Starship skeptics
Eric Berger (@SciGuySpace) 8/11/20, 2:17 PM
After speaking to a few leaders in the traditional aerospace community it seems like a *lot* of skepticism about Starship remains post SN5.  Now, [SpaceX has] got a ways to go. But if your business model is premised on SpaceX failing at building rockets, history is against you.

< Can you go into more detail about their worries? Is it just generic "new designs are always harder than they look" stuff, or is it something specific about the Starship architecture?
Eric Berger:  Everything from "They shouldn't be blowing up that many tanks" to "It's a stunt" to "they're not close to solving the technical problems."

Everyday Astronaut: So wait. [SpaceX is] already the cheapest, one of the most reliable rides to space with an increasing cadence & experience. They could ride the F9 / FH wave for 10+ years with out touching anything & take the market share. Who honestly doubts they won’t make progress w/ Starship
… As in who cares if starship never even does anything but blow up for the next 5 years and then gets canned... F9 / FH are a decade ahead of the competition already! They could scratch further advances entirely and still be a leader.

Nathan Gilmore: In my MBA we studied Kodak, IBM, BlackBerry, few others about failure to recognize but also "acknowledge" threats to their business. I suspect twenty years from now, students will study aerospace industry and how they did not see SpaceX for the threat they truly are.
< No doubt in my mind this will happen. Worst case scenario Starship isn't operational until 2031, most likely it will come into full operation by 2026, at that point it's game over for old space.

< A smarter business model might be making things that can be lifted inexpensively in those rockets.
Susan Witts:  Well, that IS an interesting point. If I can make my satellites out of steel and off-the-shelf modules, with a 3-ton impact shield and a lifetime's-worth of propellant, maybe I can out-craft my competitors with their expensive bespoke every-kilo-counts ultra-engineering?

Tony Tran:
1. Reusability is impossible
2. Reusability is unprofitable
3. Big Fat Steel rocket can't fly
4. Orbital refueling is impossible
5. You can't build a colony on Mars

Neotopiaman:  Most are so behind, it's all they have...
Starship works, then expendable rockets very soon become a rounding error in the share of tonnage to orbit.

Here's some grade-A trolling of Dmitry Rogozin by a priest from Siberia, Father Aleksandr Mikushin.

“May God the Merciful bless you [Elon Musk] and your employees for continued success in the space industry."

Mikushin continues:

"And please send some of your company’s specialists to Russia. May they teach the staffers at the Salyut Construction Bureau how to build re-usable booster stages."

< Fun fact, so when a colony is built, the colony becomes part of the diocese the ship departed from.
So, the Moon colony will likely fall under the Archdiocese of Orlando.
Which will make it the largest diocese in the Solar System.
<< But if it's a Starship launched from Texas, different diocese.

Back at Cape Canaveral, SpaceX’s Crew Dragon capsule preps for next mission
August 12, 2020 Stephen Clark
“The capsule is designed for five to 10 missions,” said Gwynne Shotwell, SpaceX’s president and chief operating officer. “We’ll have to see how things work out after we examine the capsule when it gets back to port and back to the Cape to our facilities there, but based on the telemetry and any visible indications that we’ve had so far, the vehicle looks like it’s in really good shape.”

Steve Stich, manager of NASA’s commercial crew program, said SpaceX’s proposal to reuse the Crew Dragon spacecraft “looked like it was a reasonable thing to do.”

“I think part of the question was how long does it take refurbish the vehicle,” Stich said. “It takes about four months or so. We have a lot of margin getting to the flight in the spring timeframe for Crew-2. The vehicle … as gets back to Area 59 at the Cape, it’ll start going through its maintenance.”

Stich said NASA will follow along with SpaceX’s maintenance, “just to make sure that there’s nothing untoward.” …

So in Germany, automakers are finally offering more than a tiny handful of desirable EVs.  Good!  About damn time! ;D

Not mentioned in the article:
1H2019, Tesla began mass shipping the first of its eagerly-awaited Model 3 to Europe.
1H2020, its California factory was shut down for weeks due to the pandemic.

Sales are still production-limited, not demand limited. :)
Globally, Tesla is still Number 1 — and by a large margin, if you are only counting pure EVs.  Tesla has definitely not been “crushed.” ;)
World’s Top 5 Plug-In EV Automotive Groups Ranked By Sales In H1 2020
Tesla remains #1 by a significant margin among plug-ins and is a dominant player in the BEV category.

With the first half of 2020 already behind us, let's check which automotive groups are selling the most plug-in electric cars and all-electric cars globally.

The total volume in H1 2020 amounted to about 950,000 and more than two-thirds (close to 643,000) were all-electric cars - according to EV Sales Blog.

Plug-ins (BEV+PHEvs)
The top company by sales volume among groups is Tesla with 179,050 sales, which also has expanded its market share in the overall plug-in car market from 14% a year ago to 19%!
However, the Volkswagen Group is moving fast using many of its brands and is currently #2 with 124,018 and 13% market share.
The biggest change compared to the top 5 in 2019 is the absence of Chinese groups: BYD, Geely Group and BAIC. They disappeared in Q1 2020 rank and did not manage to return yet.

Plug-in car sales in H1 2020:
   1   Tesla: 179,050 (19% share)
   2   Volkswagen Group: 124,018 (13% share)

   3   Renault-Nissan-Mitsubishi Alliance: 84,501 (9% share)
   4   BMW Group: 68,503 (7% share)
   5   Hyundai Motor Group (Hyundai, Kia): 63,731 (7% share)
Top 5 total: 519,803 (54.7% share)
others: 430,273 (45.3% share)
Total: 950,076

Battery-electric only (BEV)
Once we subtract plug-in hybrids from the equation, the top five changes a lot, as Tesla's position improved to a dominant 28% share!
Then we see the Renault-Nissan-Mitsubishi Alliance, slightly ahead of the Volkswagen Group - both with a 10% market share.
All-electric car sales in H1 2020:
   1   Tesla: 179,050 (28% share)
   2   Renault-Nissan-Mitsubishi Alliance: 65,521 (10% share)
   3   Volkswagen Group: 64,542 (10% share)

   4   BYD: 46,554 (7% share)
   5   Hyundai Motor Group (Hyundai, Kia): 43,689 (7% share)
Top 5 total: 399,356 (62.1% share)
others: 243,621 (37.9% share)
Total: 642,977

Elon Musk Splits Stock, Makes Tesla's Case to Join Dow Jones
Until Tuesday, there was one seemingly insurmountable obstacle that would have made Tesla getting into the Dow Jones Industrials impossible. Its stock price of nearly $1,400 per share as of the Aug. 11 close would've made it an impractical choice to join the price-weighted average, because its influence over the entire Dow Jones Industrials would've been unjustifiably high. Even now, the fact that Apple has a nearly 11% weighting in the Dow is somewhat controversial, and that's with Apple's share price of just $450. The idea of having Tesla represent 30% was a complete nonstarter.

Yet Musk surprised just about everyone by doing something that Tesla has never done before: splitting its stock. It announced a 5-for-1 split for owners of record on Aug. 21, with shares to start trading on a split-adjusted basis a week and a half later on Aug. 31.

To be clear, Tesla's board of directors didn't explicitly say it's trying to join the Dow. In its press release, the company cited the desire to "make stock ownership more accessible to employees and investors." Yet with the advent of fractional share trading, that's an increasingly difficult argument to make. ...

Dow Jones vs. NASDAQ vs. S&P 500: The Differences

The Dow Jones Industrial Average is a price-weighted average of 30 significant stocks traded on the New York Stock Exchange (NYSE) and the Nasdaq. The DJIA was invented by Charles Dow in 1896.

Earl: Yep. They actually specifically said they are not a Tesla killer. Won’t stop the news

Covid-19 is here to stay. People will have to adapt
The world is not experiencing a second wave: it never got over the first
IT IS ASTONISHING how rapidly the pandemic has spread, despite all the efforts to stop it. On February 1st, the day covid-19 first appeared on our front cover, the World Health Organisation counted 2,115 new cases. On June 28th its daily tally reached 190,000. That day as many new cases were notched up every 90 minutes as had been recorded in total by February 1st.

The world is not experiencing a second wave: it never got over the first. Some 10m people are known to have been infected. Pretty much everywhere has registered cases (Turkmenistan and North Korea have not, though, like Antarctica). For every country such as China, Taiwan and Vietnam, which seems to be able to contain the virus, there are more, in Latin America and South Asia, where it is raging. Others, including the United States, are at risk of losing control or, in much of Africa, in the early phase of their epidemic. Europe is somewhere in between.

The worst is to come. Based on research in 84 countries, a team at the Massachusetts Institute of Technology reckons that, for each recorded case, 12 go unrecorded and that for every two covid-19 deaths counted, a third is misattributed to other causes. Without a medical breakthrough, it says, the total number of cases will climb to 200m-600m by spring 2021. At that point, between 1.4m and 3.7m people will have died. Even then, well over 90% of the world’s population will still be vulnerable to infection—more if immunity turns out to be transient.

The actual outcome depends on how societies manage the disease. Here the news is better. Epidemiologists understand how to stop covid-19. You catch it indoors, in crowds, when people raise their voices. The poor are vulnerable, as are the elderly and those with other conditions. You can contain the virus with three tactics: changes in behaviour; testing, tracing and isolation; and, if they fail, lockdowns. The worse a country is at testing—and many governments have failed to build enough capacity—the more it has to fall back on the other two. Good public health need not be expensive. Dharavi, a slum of 850,000 people in Mumbai, tamed an outbreak (see article).

Treatments have improved, thanks to research and dealing with patients. Although mass vaccination is still months away at best (see article), the first therapies are available. More is known about how to manage the disease—don’t rush to put people on respirators, do give them oxygen early. Better treatment helps explain why the share of hospital patients who went on to be admitted to intensive care fell in Britain from 12% at the end of March to 4% in mid to late May.

And economies have adapted. They are still suffering, of course. J.P. Morgan, a bank, predicts that the peak-to-trough decline in the first half of the year in the 39 economies it follows will be around 10% of GDP. But workers stuck in Zoom hell have discovered that they can get a surprising amount done from home. In China Starbucks designed “contactless” ordering, cutting the time customers spend in its coffee shops. Supply chains that struggled now run smoothly. Factories have found ways to stagger shifts, shield staff behind plastic and change work patterns so that personal contact is minimised.
Now that nationwide lockdowns are done, governments can make sensible trade-offs—banning large indoor gatherings, say and allowing the reopening of schools and shops. Sometimes, as in some American states, they will loosen too much and have to reverse course. Others will learn from their mistakes.

The problem is that, without a cure or a vaccine, containment depends on people learning to change their behaviour. After the initial covid-19 panic, many are becoming disenchanted and resistant. Masks help stop the disease, but in Europe and America some refuse to wear one because they see them as emasculating or, worse, Democratic. Thorough handwashing kills the virus, but who has not relapsed into bad old habits? Parties are dangerous but young people cooped up for months have developed a devil-may-care attitude. Most important, as the months drag on, people just need to earn some money. In the autumn, as life moves indoors, infections could soar.

Changing social norms is hard. Just look at AIDS, known for decades to be prevented by safe sex and clean needles. Yet in 2018, 1.7m people were newly infected with HIV, the virus that causes it. Covid-19 is easier to talk about than AIDS, but harder to avoid. Wearing a mask is chiefly about protecting others; the young, fit and asymptomatic are being asked to follow tedious rules to shield the old and infirm.

Changing behaviour requires clear communication from trusted figures, national and local. But many people do not believe their politicians. In countries such as America, Iran, Britain, Russia and Brazil, which have the highest caseloads, presidents and prime ministers minimised the threat, vacillated, issued bad advice or seemed more interested in their own political fortunes than in their country—sometimes all at once.

Covid-19 is here for a while at least. The vulnerable will be afraid to go out and innovation will slow, creating a 90% economy that consistently fails to reach its potential. Many people will fall ill and some of them will die. You may have lost interest in the pandemic. It has not lost interest in you.

Tesla (TSLA) declares five-for-one stock split

Tesla (NASDAQ: TSLA) has announced that its Board of Directors has approved a 5:1 split for the company’s common stock in the form of a dividend. The move will make the ownership of TSLA stock more available for both employees and investors alike.

The electric automaker stated that each stockholder of record on August 21, 2020, will receive a dividend of four additional shares of common stock for each share that the investor held on that date. It will be distributed after the closing bell on August 28, 2020.
Trading will then begin on a stock split-adjusted basis on the following trading day, which is Monday, August 31.

Stock splits, or stock divides, are used to increase the number of shares in a company. The act of splitting a stock will decrease the market price of individual shares, but it will not affect the total market capitalization of the company that chooses to perform the split.
The move could help smaller investors afford TSLA stock, which has tripled in value since the beginning of the year.

TSLA stock closed at $1,374.39 today, but aftermarket trading has brought the price of the stock back up by nearly 6%. At the time of writing, the stock was being traded at $1,453.55. ...

Starlink: SpaceX’s 100th mission may break an incredible reusability record
SpaceX's upcoming launch could raise the bar for reusing rockets.
SpaceX may be about to take another step in its plan to reuse space rockets.
The company is expected to send up its 11th batch of Starlink satellites in mid-August, sending up 58 craft from Space Launch Complex 40 at the Cape Canaveral Air Force Station in Florida. The mission is also expected to send up three SkySat imagine satellites for Planet as part of a ride-sharing agreement, after the company previously hitched a ride in a Starlink mission in June. The extra satellites will be used to help bring SpaceX's high-speed, low-latency internet connectivity constellation to life.

But SpaceX's mission could be notable for its impressive use of rocket reusability. Eric Berger, senior space reporter at Ars Technica, claimed via Twitter last week that the mission could use a booster that has previously flown five times. This would be the sixth mission for booster B1049, the first time SpaceX has flown the same first-stage rocket that many times.

As Twitter user Simon Merton noted in response, this could be SpaceX's 100th mission. The website SpaceXStats notes that the company has launched 99 missions. Of those, five were with the Falcon 1 rocket, 91 with the Falcon 9 rocket, and three with the Falcon Heavy. SpaceX's first successful launch, and fourth launch overall, was in 2008.

Reusing rockets forms part of its mission to make spaceflight more accessible for all. Landing a booster after flight saves approximately $46.5 million of the $62 million price tag associated with a Falcon 9 launch. That means saving the booster enables SpaceX to reduce the costs of spaceflights even further, which in turn can fund more ambitious projects like a city on Mars. …

The remaining question:  How big is the Lucid Air’s battery?

Lucid claims the high voltage and other improvements helped the car be so efficient, but rumor has it its battery pack will be below 130 kWh. If that is the case, it would be about 30 percent larger than the 100 kWh battery pack currently on the Model S.

Not by chance, the difference between 517 miles and 402 miles is 115 miles – or 28.6 percent more than what the Model S offers. We would not doubt if the Air's battery pack was 128.6 kWh. ...
Lucid Makes Tesla Eat Dust With Air's Estimated 517-Mile EPA Range

Policy and solutions / Re: Electric cars
« on: August 11, 2020, 04:20:50 PM »
Meanwhile, Lucid actually knows what needs to be done:
“I am therefore pleased that we have consequently achieved an estimated EPA 517 miles of range today whilst also significantly reducing our battery pack’s capacity, thereby reducing vehicle weight and cost, and improving interior space. Such exceptional efficiency, achieved through in-house technology, is undeniably a measure of a true EV tech company.”

Lucid Air to top Tesla Model S with astonishing 517-mile estimated EPA range
Lucid’s upcoming all-electric luxury sedan, the Air, will boast 517 miles of battery range per single charge, making it the longest range electric vehicle in the industry.

Lucid’s range tests for the Air were secured at FEV North America, Inc. in Auburn Hills, Michigan where it conducted trial runs utilizing the EPA’s Multicycle Test Procedure (SAE J1634 Oct 2012 Standard) with the standard adjustment factor.

The results indicated that the Air would have a 745-mile city range rating and a 730-mile highway rating, giving the vehicle a 738-mile combined unadjusted range estimation. After the adjustment factor, the range was estimated to be 517 miles of EPA range, beating the Tesla Model S, which holds the current production vehicle record for the longest range at 402 miles per charge.

Rawlinson, a former Tesla Chief Engineer who worked on the Model S, has been heavily focused on the aerodynamic development of the Lucid Air. After testing the Air’s aerodynamic performance at the Windshear facility in North Carolina, it was determined that the vehicle had a drag coefficient of .21, beating the Model S (.23) and Porsche Taycan (.22).

Aerodynamic efficiency plays a key role in achieving world-beating range and performance and is particularly valuable to an EV in that it provides ‘smart range’ independent of battery pack size,” Rawlinson said in June. “So naturally, we intensively focused upon aerodynamics throughout the Lucid Air’s development.”

Range and efficiency are widely recognized as the most relevant proof points by which EV technical prowess is measured,” Rawlinson said. A few years ago, Lucid revealed that it had achieved a 400-mile range vehicle. Still, the company planned to develop and continue improving upon the foundation it had set for the Air to become the most efficient electric car on the market.

“I am therefore pleased that we have consequently achieved an estimated EPA 517 miles of range today whilst also significantly reducing our battery pack’s capacity, thereby reducing vehicle weight and cost, and improving interior space. Such exceptional efficiency, achieved through in-house technology, is undeniably a measure of a true EV tech company,” Rawlinson added.

The production version of the Air will be revealed during an online event on September 9, 2020. Information on the vehicle’s interior and exterior designs, as well as specifications, configurations, and pricing options, will also be shared during the event.

Cadillac has revealed the vehicle that will kick off its electric future... which is still two years away.

After earlier postponing their planned reveal of the Cadillac Lyriq due to the pandemic, GM had an on-line event August 6.
Electric 2023 Cadillac Lyriq revealed as brand shifts to battery power
The Lyriq is a midsized SUV with a promised range of over 300 miles between charges that is scheduled to go on sale in the U.S. in late 2022, when it will become Cadillac’s first all-electric vehicle and compete with models like the Audi E-Tron Jaguar I-Pace and Tesla Model X.

Offered in rear-wheel-drive and all-wheel-drive models, the Lyriq is powered by GM’s upcoming Ultium battery, which is more advanced than the current technology used in the Chevrolet Bolt.

GM North America president Steve Carlisle said pricing for the Lyriq will start under $75,000 and that the brand is aiming to offer electric versions of its entire lineup by 2030.

"Our objective is to offer over 300 miles range on what we’re doing with these products and the variants on these products. But we’re still in the development phase of the program"
Translation: We hope we can hit 300 but we have no clue

well, they have the right idea of what they need to build. Lyriq looks like a compelling product.
but can they actually build it? doesn’t look like they have a near production prototype.
And they’re relying on LG chem for batteries? Let’s see when it starts production...

"In 2019, we partnered with Iveco, a subsidiary of CNHI, to manufacture the Nikola Tre BEV truck at the Iveco manufacturing plant in Ulm, Germany through a JV with CNHI, which is expected to commence operations in the third quarter of 2020."

According to 10-Q filing for Q2-2020, the only binding reservations are for the "up to 800 trucks" in the Anheuser-Busch contract but these are cancellable if Nikola does not fulfill its commitment regarding delivery timeline (i.e. December 31, 2021) which it won't & can't. $NKLA

Some thoughts on Tesla’s Autopilot & Robotaxi strategy:
1) I believe Tesla has a unique & superior strategy for solving Robotaxis which I categorise as the Intelligence/Data heavy approach, based on the assumption that Robotaxis are a very difficult intelligence problem to solve.
2) This is opposed to the approach of the rest of the industry which I would categorise as hardware heavy, Intelligence/data light which is based on the assumption that self driving is a relatively easy intelligence problem. I’ll explain this more later.

A: When solving Robotaxis, prediction is the hard problem – it requires a lot of intelligence and experience. Detection is easier.
B. Hence our strategy should be optimised to solving prediction, not detection.
12) C. To solve prediction of other objects paths we need billions of miles of real world driving experience to train the cars to understand the universe it is interacting with and to be able to solve enough edge cases to beat human driving accuracy by 2-10x.
13) D) We can't get billions of miles of driving experience without a hardware suite affordable to install in a consumer owned car.
E)Lidar won't be cheap enough to install in a high volume consumer car in a reasonable timeframe (& also has issues with rain & lidar interference)
14) F). Therefore we cannot use Lidar, even though it is a shortcut to solving the detection problem because it can easily measure distance and velocity of objects with hardware rather than software & intelligence. …

—- The Military Launch Contract: Another Perspective
SpaceX, ULA win multibillion-dollar military launch contract years in the making
…  Regardless of the missed opportunities, the NSSL LSA Phase 2 contract is a major win for SpaceX and guarantees the company’s Falcon 9 and Falcon Heavy rockets some 13-14 military launch contracts over a five-year period. For ULA, the victory is like a massive relief, given that the company’s next-generation (expendable) Vulcan Centaur rocket has next to no chance of sustaining itself with commercial launch contracts. Much like Atlas V in the last decade of the rocket’s life and Delta IV over most of its two-decade career, ULA’s Vulcan rocket will continue the trend of relying almost exclusively on US military contracts.

This time around, however, the US military’s preferential treatment of ULA is nakedly obvious. At almost every turn, SpaceX’s Falcon 9 and Falcon Heavy rockets can provide the same launch services as ULA for anywhere from 20-50% less. For the few missions (direct to geostationary) where ULA’s Atlas V, Delta IV, and Vulcan rockets might actually have a step up over SpaceX, the US could have easily awarded ULA the smaller 40% share or even split that 40% share with Blue Origin or Northrop Grumman, giving SpaceX the lion’s share and likely saving hundreds of millions of dollars – if not $1B+ – over the next seven years.

Instead, business (more or less) as usual will continue for at least another decade as the US military functionally subsidizes ULA’s existence by prioritizing a more expensive rocket to achieve the same outcome. The first LSA Phase 2 launches are currently scheduled to begin no earlier than (NET) 2022.

“Beef is clearly declining as a percentage of total meat production, from 39% in 1961 to only 20% in 2018. Pork is exactly the same percentage of total meat production now as it was in 1961: 35%. All of the growth has come from chicken, which has more than tripled from 11% to 34% of total meat production.”

The World Is Finally Losing Its Taste for Meat
Production is projected to dip for the second year in a row, and there’s reason to believe we’re already falling out of love with beef.
August 8, 2020
Global consumption of animal proteins has been rising, apparently inexorably, for the past six decades. The coronavirus pandemic has finally changed that trajectory.

The Food and Agriculture Organization of the United Nations estimates that meat production—a decent proxy for consumption—dropped in 2019, and it forecasts a decline again this year. Last year was only the second since 1961 in which production fell; two consecutive years of decline is unprecedented and could be the start of something durable. We’re already at peak pasture as far as demand is concerned, and it looks like we’re also approaching peak beef, even in places like steak-crazed Brazil.
But by any number of measures, beef consumption looks very near its peak, and the investors betting more than $1 billion on alternative proteins this year are hoping that their portfolio companies can drive meat demand down further. For now though, the easiest and the nearest-term solution for reducing land use emissions is simply to use less land. Substituting chicken for beef does this already on the margin; a measurable shift away from beef consumption could take that trend much further. …

COVID-19 was cited as the reason for 63,517 job cuts in July. The respiratory illness has been blamed for 1.075 million layoffs so far this year. The balance of job cuts in July were attributed to market conditions, a downturn in demand and bankruptcies.

Job cuts announced by U.S. companies jump 54% in July: report
U.S. employers announced another 262,649 job cuts in July as the COVID-19 pandemic continued to weigh on demand, the latest indication that the labor market recovery is losing steam.

“The downturn is far from over, especially as COVID cases rise around the country,” said Andrew Challenger, senior vice president at Challenger, Gray. “Consumers are buying fewer goods and services, businesses are closing, and bankruptcies are rising.”.

Several retailers including J.C. Penney and Lord & Taylor have filed for bankruptcy since March. Job cuts remained concentrated at bars, restaurants, hotels and amusement parks. The automotive sector cut 83,853 jobs.

“It is clear that many job losses are now permanent, and it will be challenging for many workers to find new jobs and feel safe taking jobs that are public-facing,” said Challenger.

NASA awards DART launch contract to SpaceX
April 11, 2019
SpaceX will launch a NASA mission to test an asteroid deflection technique at a significantly lower price than past agency contracts won by the company.

NASA said April 11 it awarded SpaceX a contract to launch the Double Asteroid Redirection Test (DART) on a Falcon 9 in June 2021 from Vandenberg Air Force Base in California. The total cost to NASA for the mission, including the launch and related services, is $69 million.

DART is a mission under development at the Johns Hopkins University Applied Physics Laboratory as part of NASA’s planetary defense program. The spacecraft will use an electric propulsion system to travel to the asteroid Didymos. DART will collide with a small moon orbiting Didymos, sometimes nicknamed Didymoon, at a speed of six kilometers per second.

Astronomers will measure the change in the moon’s orbit around Didymos as a result of the impact to measure how well the energy of the impact was transferred to the moon. That will help scientists gauge the effectiveness of the “kinetic impactor” approach proposed as one means of deflecting an asteroid on a collision course with the Earth.

DART originally planned to launch as a rideshare on the commercial launch of a geostationary orbit satellite. The mission switched several months ago to a dedicated launch. NASA did not disclose if DART, which weighs about 500 kilograms, will share the launch vehicle with another spacecraft. …

South Korea mulls exiting its own launch program. South Korean defense industry analysts say the nation would have difficulty competing with other countries in the launch industry, which can provide more advanced technologies and services at lower prices with their already established space-industry infrastructure. "Even if South Korea develops its own rockets, they would not be able to excel more than aerospace giants like SpaceX in terms of technology," said Shin Jong-woo, a senior researcher at the Korea Defense and Security Forum, in The Korea Times.

Ten times the cost ... The country's space institute, KARI, has developed several small-satellite rockets, but these are not competitive with SpaceX's Falcon 9, which recently launched South Korea's first military communications satellite, ANASIS-II. "The costs spent by the South Korean government to develop the two rockets were 10 times higher than those spent by SpaceX," Kim Seung-jo, former president of KARI, said. "But the South Korean government's outcomes in its rocket projects were far behind the Falcon 9 rocket produced by SpaceX."

Nissan Leaf drivers in Japan can now pay for parking with electricity from their vehicle.
The proof-of-concept experiment, at Nissan’s Pavilion exhibition space in Yokohama, allows EV owners to pay for their stay by feeding battery power back into a localised grid.
The Pavilion opened on August 1, 2020, and will run until October 23. It is an arena for the Japanese manufacture to show off new technologies.
“The Pavilion is a place where customers can see, feel, and be inspired by our near-future vision for society and mobility,” said Nissan CEO Makoto Uchida.
“As the world shifts to electric mobility, EVs will be integrated into society in ways that go beyond just transportation.”
Practical implementation of the displayed energy storage and sharing systems is still in its early stages, however Nissan has reportedly entered into agreements with local governments to use their vehicles as mobile battery units during natural disasters.

Coronavirus hastens Big Oil's Atlantic divide on climate change
The big picture: Economic shutdowns around the world in response to the coronavirus choked off oil demand at a time when the industry was already awash in too much of the fuel and struggling financially. Now, the world may be changing in permanent ways that tilt society away from what has been a steadily growing demand for oil despite rising concerns about its impact on the planet.

“The coronavirus crisis has, all of a sudden, accelerated at least the potential that oil demand will plateau,” said Martijn Rats, global oil strategist at Morgan Stanley.

Persistently low oil prices are making other sources more intriguing investments. “The profitability of investing in renewables versus oil and gas is an awful lot closer now.”

How it works: Europe’s more progressive governments and investors are major reasons why its oil companies are looking to evolve compared to their U.S. counterparts.

SpaceX launches tenth Starlink mission, nails booster’s fifth landing
By Eric Ralph August 6, 2020 
While Starlink-9 was originally scheduled to launch as early as June 23rd, Principal Integration Engineer John Insprucker – a familiar fixture and voice on SpaceX webcasts – was quick to note that through the more than six subsequent weeks of delays, “Falcon 9 has been trouble-free.” He also partially answered the main question on everyone’s mind, noting that all of those delays could be traced back to bad weather and issues with the mission’s payloads.

Notably, the next two non-Starlink launches currently on SpaceX’s manifest are SAOCOM 1B – the first polar orbit launch from the East Coast in half a century – and Crew-1 – Crew Dragon’s first operational astronaut launch. Scheduled no earlier than late-August and late-September, respectively, both major customer missions are likely to be punctuated by several Starlink launches over the next two months. With Starlink-9 complete, SpaceX could be just 4-5 missions away from rolling out Starlink internet service according to a comment from COO/President Gwynne Shotwell that service could begin after the 14th Starlink launch. ...

Nikola’s Q2 earnings call this week mostly consisted of them reading the SEC filing.  They refused to give a number of Badger reservations, and still have not contracted with an OEM to build it.

They also revealed that each hydrogen station will take 18 months to build, and no production is expected this year.
ALEX  (@ajtourville) 8/5/20, 1:36 PM
Nikola signed the contract with Anheuser-Busch in February 2018 which stipulates Nikola must provide hydrogen trucks & hydrogen fueling stations for each of the 13 AB locations in the Network by December 31, 2021.
~ 7/9
30 months after signing the Anheuser-Busch contract, Trevor Milton says Nikola hasn't even determined the location of the first 2 hydrogen stations & that it will take Nikola 18 months to assemble each Nel plug & play station!
~ 8/9
Not to mention Nikola only began the beta engineering of its hydrogen truck in Q1-2020 & that it isn't even scheduled to go into production until 2023!

The “factory” in Ulm, Germany where the BEV Nikola Tre is to be made is a small warehouse with no assembly equipment visible in the SEC photos.  (One photo shows a long-abandoned, empty space.)   The “Business Outlook” section of the filing is exactly three lines, saying only that they plan to begin “testing” (of some sort) in 2021 before proceeding to “low volume production” of the Nikola Tre (no time frame given).

Nikola Tesla’s Ghost  (@Nikola_Truth) 8/4/20, 4:37 PM
So what was once ‘12 months’ and became ‘mid to late next year’ is actually at best late next year.
Even then, that’s probably still optimistic.

The only Q2 revenue in the filing is $36,000 (reported as “$0.04 million”) which Trevor Milton paid the company to install solar panels on his house in Utah.
< $0.04 million is the cutest way I’ve ever seen to say $40,000  This year, they also built 0.0 million vehicles.

"Is this all we get?" Paul Coster of JPMorgan asked. Jeff Osborne, an analyst at Cowen, said Nikola's rollout timeline is "a bit confusing."
Tesla competitor Nikola sinks 17% after debut earnings report misses forecasts and analyst call turns contentious

Why Nikola Stock Fell Sharply After Earnings
Investors would have been delighted to hear that Nikola has a manufacturing partner for its electric Badger pickup -- but no news was forthcoming on Tuesday.

Nikola's stock is down because the company missed a different set of expectations. As Deutsche Bank analyst Emmanuel Rosner said in a note on Monday, before Nikola reported, investors were expecting news on any of several fronts.

News of (for instance) new fleet customers for Nikola's upcoming battery-electric semi, an announcement of a commercial partner for its hydrogen refueling network, or a manufacturing partner for its Badger pickup truck could have pushed the stock significantly higher. …

Las Vegas tunnel project clears last major hurdle for expansion
Aug 5 2020
On Wednesday, county officials unanimously approved designs for two additional tunnels connecting hotels with the Las Vegas Convention Center, clearing the way for Musk’s Boring Co. to expand its first commercial underground transportation system.

Approval form the Clark County commission is one of the last hurdles to a proposed expansion of a Boring Co. project burrowing underneath the convention center, which was largely finished in May but has yet to open for rides. One of the hotels connecting to the Loop, Resorts World, said it expects construction on the expansion to begin by the end of this year, Scott Sibella, president of Resorts World Las Vegas, said in an emailed statement.

In May, Musk tweeted that Boring Co. would “also connect Vegas hotels & airport.” Airport officials have held introductory conversations with the Boring Co. in recent weeks, according to Chris Jones, a spokesman for McCarran International Airport.

With the coronavirus pandemic curbing travel, including to Las Vegas, Boring Co. and its hotel partners may benefit from some extra time to get their projects ready. Boring Co. has said it’s on track to finish the Vegas convention center Loop by January, in time for the massive Consumer Electronics Show, though conference organizers said last week that the event will be held exclusively online. A Boring Co. Loop to Dodger Stadium in Los Angeles is still mired in the city’s environmental review process and missed a deadline for opening this year that had been set by the baseball team’s financial chief. ...

Just so we're clear, SpaceX built a Mars rocket out of rolls of steel, in tents, in South Texas, in weeks. And the first time they flew it, it made a smooth launch, a controlled flight, and safely landed. This is truly remarkable.
Eric Berger: Mars is still long freaking way away. So very far. But the first step is low-cost, frequent access to space for tons of stuff. This is the first step toward that first step. And it's a big one.

Honda Electric Car Is Range And Price Challenged, But Technology, Quality Are Plusses
Cars like the Renault Zoe (240 miles) and the Peugeot 208 e (220 miles) are priced very close to the Honda e but are bigger, and have this huge almost double advantage in range. Honda counters with the argument that the interior quality of the “e” is in a higher class, and the technology offered is also worth paying for. Honda says that for most daily commuters, the range of 125 miles would be more than adequate, while its fast charging is top class. Honda says it can be 80% recharged in 30 minutes.

Starship’s landing legs are hidden under the bottom “skirt,” and thus are not easily visible while on the launch mount, but they extend for landing.

Michael Baylor (@nextspaceflight) 8/4/20, 10:03 PM
Sounds like the plan is now to get more experience with the launch process. Makes sense, given that a lot of the ground support equipment and systems on the vehicle are new. Perhaps, SN6 will get to fly to 150 meters too!

Elon Musk (@elonmusk) 8/4/20, 9:17 PM
V1.1 legs will be ~60% longer. V2.0 legs will be much wider & taller — like Falcon, but capable of landing on unimproved surfaces & auto-leveling.

The single Raptor engine in SN5 is mounted off-center, because future prototypes will have 3 Raptors in a triangular configuration, per Elon Musk.  That is why the rocket does a “power slide” off the launch mount and the engine does not thrust straight down.  SN5 also rolled (rotated) approximately 90° during its flight, testing the ‘steering’ thrusters.

Trevor Mahlmann (@TrevorMahlmann) 8/4/20, 8:20 PM
There for 20m.
There for 120m.
Here for 150 m.

With certainty, I can say, offset thrust is the best thrust.

Looking Back on a Revolution: Tesla Model 3 Turns Three
Jul 29, 2020
Tesla's Master Plan
In 2006, Tesla CEO Elon Musk posted Tesla's secret master plan online for the world to see.

"So, in short, the master plan is:
Build sports car
Use that money to build an affordable car
Use that money to build an even more affordable car
While doing above, also provide zero emission electric power generation options"

2008: Tesla delivered the first Tesla Roadster. Check.
2012: Tesla delivered the first Model S. Check.
2016: Tesla acquired Solar City. Check.
2017: Tesla delivered the first Model 3. Check.

Project BlueStar
On July 28, 2017—three years ago today—Tesla's decade-long master plan came to fruition when Tesla handed over the first BlueStar, now known as Model 3, vehicles to customers. The goal for BlueStar was clear from the start: drive volume.

"With BlueStar, we're looking at cost and lowering the overall expense to the user. If it's not cost-competitive (with oil), you are going to have a hard time scaling to a high level." - Tesla co-founder JB Straubel to CNET, 2008

While scaling to a high level has not been without challenges, the Model 3 has cemented its revolutionary status by quickly becoming the best-selling electric vehicle in history despite 5-10 year head starts from runners-up.

But it's not just other EVs that the Model 3 has overthrown. In the United States, the Model 3 has outsold competing premium internal combustion engine sedans: the Mercedes C-Class, BMW 3 Series, Audi A4 and S4, Lexus IS, and Jaguar XE. Combined. ...
