LNG: TESLARATI

Recent reports have emerged suggesting that Tesla may complete its purchase contract for the site of Gigafactory 4, which is located near Berlin in Germany, before the end of 2019. A special meeting of the Finance Committee about the facility’s permit could be held as early as the week before Christmas, at around the 17th of 18th of December. The recent recent update was related by Brandenburg’s Finance Minister Katrin Lange (SPD) during a meeting on Thursday.

Elon Musk aims to start producing the Tesla Model Y crossover at the Germany-based site as early as 2021. This is an ambitious target, and one that would be challenging considering that the electric car maker would still need to wait for a lengthy test procedure from the country’s authorities before the upcoming facility could be built. 

That being said, the district of Oder-Spree, where Gigafactory 4 will be located, wants the project to move quickly. This was related by Landrat Rolf Lindemann in a previous statement to the German Press Agency. “We stand rifle by foot. When the first planning documents arrive tomorrow, we start immediately,” Lindemann said. 

Lindemann explained that the district will proceed with care when adhering to Gigafactory 4’s legal framework. The District Administrator further noted that he is optimistic about Tesla’s factory, considering that the area had already been planned for a BMW facility back in 2001. “This is already the development plan for this type of industrial use,” he said. 

It should be noted that the area Tesla is aiming to acquire for Gigafactory 4 requires approval from conservation groups. In comments to the German Press Agency, National Chairman of the Brandenburg Nature Conservation Union Friedhelm Schmitz-Jersch stated that the development plans for the site that were granted for BMW’s potential facility would need to be re-examined, particularly as the flora and fauna in the area may have changed since 2001. “One must now grasp which species worth protecting are there. Is what was then still valid today?” he said. 

Tesla, for its part, has stated that it intends to plant three times as many trees that it would uproot for Gigafactory 4’s construction.

Tesla’s Gigafactory 4 came as a surprise announcement from CEO Elon Musk during a recent visit to Germany. Musk was in the country to accept the Golden Steering Wheel Award for the Model 3, and while speaking with the host of the ceremony, the Tesla CEO dropped the news that Gigafactory 4 will be constructed in the country. An engineering and design center will also be constructed in Berlin. 

“Everyone knows that German engineering is outstanding, for sure. That’s part of the reason why we are locating our Gigafactory Europe in Germany. We are also going to create an engineering and design center in Berlin, because Berlin has some of the best art in the world,” Musk said.

SpaceX says Crew Dragon’s upgraded “Mk3” parachutes are almost ready to safely return astronauts to Earth and need to pass just a few more consecutive tests before NASA will have the data it needs to qualify them.

Although SpaceX originally hoped to pursue a program of propulsive landing for Crew Dragon and Cargo Dragon space capsules, that effort was canceled to avoid the major cost increases and delays NASA’s qualification certification requirements would have triggered. Already designed with parachutes as a backup, SpaceX quickly pivoted and redesigned those parachutes as the primary (if not sole) method of gently landing astronauts back on Earth.

That decision was likely made in late 2016 or early 2017 and CEO Elon Musk announced the program’s cancellation – as well as plans for “Red Dragon” Mars landings – in July 2017. For the next 18 months, SpaceX worked with suppliers and NASA to design and test a parachute system up to the space agency’s extremely rigid standards. Coincidentally, Cargo Dragon suffered a significant (but survivable) parachute failure the same year when one of its three main chutes failed to deploy before splashdown. Additionally, Crew Dragon’s first “Mk1” parachutes suffered their own failures during testing.

A Mk2 variant was designed and built to account for Mk1’s issues, but it too suffered failures during field tests, particularly struggling to make it through tests simulating the failure of one Dragon’s main parachutes. As a result, NASA further required SpaceX to add a fourth parachute, requiring a whole new round of tests and experimentation due to the significantly different dynamics it introduced. Mk2 testing continued into 2019 but SpaceX quickly switched gears and worked with its supplier to design an even more upgraded “Mk3” parachute, building off of a cutting-edge program to model parachute deployment more accurately than ever before.

Over the course of 2019, SpaceX began to extensively test Mk3 parachutes with a variety of drop tests. Unfortunately, even Mk3 suffered a failure or two at first, leading SpaceX and its supplier to refine the design even further.

“[In October and November,] SpaceX says it successfully completed thirteen consecutive tests of Crew Dragon’s new Mk3 parachutes in less than two weeks. That essentially blew [NASA administrator Jim] Bridenstine’s expectations out of the water, as SpaceX surpassed his predicted 10 tests and did so barely three weeks into the tentative 12-week window he set. SpaceX now has plenty of time to either continue testing Crew Dragon’s parachutes or refocus its efforts on other equally important qualification challenges.

Prior to those thirteen consecutive successes, SpaceX suffered two failures during single-parachute Mk3 testing. The first two development tests of the Mk 3 design used loads much higher than the parachutes would ever see in operation in an effort to better understand overall design margins and system performance. After a period of rapid iteration with parachute provider Airborne Systems, the faults responsible for those two stress-test failures were resolved and subsequent drop tests confirmed that Mk3’s suspension lines – the numerous lines connecting the parachute to Crew Dragon – are far stronger than those on Mk2.”

Teslarati — November 3rd, 2019

In the latest chapter of the Crew Dragon parachute saga, on December 4th, SpaceX tweeted that the spacecraft’s upgraded Mk3 chutes recently completed their seventh successful “system test”. On November 3rd, CEO Elon Musk tweeted that one such multi-chute test had already been completed but said SpaceX wanted to successfully complete ten such consecutive tests before it would feel fully confident in the upgraded parachutes.

If the seven tests SpaceX is now describing are part of the same planned series that kicked off in early November, then those seven were likely consecutive successes and leave just three more tests (give or take) to go. Additional testing may well be required by SpaceX, NASA, or both parties, but if Mk3 continues to perform as well as it has over the last two months, Crew Dragon’s recovery systems ought to be well on their way to NASA certification. Once NASA gives the go-ahead on Crew Dragon’s parachutes (and every other facet of the spacecraft), SpaceX can proceed with its Demo-2 mission, set to be SpaceX’s inaugural astronaut launch and likely to mark the first time the US has launched its own astronauts in nearly nine years.

Tesla Cybertruck will be able to support extended-length cargo via a flip-up load stop on its tailgate, according to CEO Elon Musk.

Tesla fan Ron Pomeroy presented the potential problem to Musk, specifically the loading of a large sheet of 4’x8′ plywood which exceeds the electric pickup truck’s 6.5 ft. “vault” bed length. “Elon, nice owl. Now, how should I transport a standard 4X8 sheet of plywood in my Cybertruck? Can you add a flip stop to the tailgate?” noted Pomeroy over Twitter, to which Musk confirmed with a “yes”.

The flip stop, that’s in question, is a built-in flap on the inward side of a pickup truck’s lift gate that flips out and prevents long cargo from sliding off the truck bed. The section is hinged to the tailgate and can be folded back down when not in use. It’s essentially a tailgate within a tailgate.

Finally found it – a ‹Flip Stop› is a small section that flips up form the inside of the tailgate when it is flat, to act as a stop for goods being carried. Eg: pic.twitter.com/6RXPc7kicT

Yes

— Elon Musk (@elonmusk) December 3, 2019

While the current prototype of the Tesla Cybertruck does not incorporate a flip stop to its design, adding one can only increase the versatile utility of the truck. Cybertruck will have a modular truck bed system that can include a Cybercamper and kitchen attachment. Similar in amenities to the all-electric Rivian R1T, such adaptability can be the convincing factor that pushes consumers to transition to all-electric pickup trucks.

Auto experts have also praised the new member of the Tesla garage. Jack Rickard foresees the Cybertruck to become astonishingly successful.

As Musk announced during the unveiling of the Cybertruck, Tesla’s electric ATV will come as an option. He also hinted that the Boring Company “Not-a-Flamethrower” may also be included.

The entry-level Cybertruck boasts of a towing capacity of over 7,500 lbs, a range of over 250 miles, and sprinting capability from 0 to 60 in less than 6.5 seconds. It offers a storage capacity of 100 cu.ft. It is Tesla’s boldest vehicle to date with a starting price of $39,990 that also shocked the electric vehicle community. Autopilot will also come as a standard feature along with an adaptive air suspension that can adjust to heavy loads and prevent the vehicle from being mangled.

There are many criticisms of electric vehicles like Teslas, and one of them involves the notion that EVs require massive amounts of water to produce the lithium in their batteries. This idea, according to Dr. Maximilian Fichtner, who serves as the Director at the Helmholtz Institute for Electrochemical Energy Storage in Germany, is not accurate at all. 

In a recent conversation with Tagesspiegel Background, the battery researcher stated that the production of electric car batteries is not as extreme as what EV critics would suggest. To produce the lithium needed for a 64 kWh battery pack, for example, Fichtner stated that about 3840 liters of water are evaporated according to usual calculation methods. This is roughly comparable to the production of 250 grams of beef, 30 cups of coffee, or half a pair of jeans, according to the researcher. 

Explaining further, Fichtner stated that even before electric cars like Teslas became popular, lithium was already being used in large quantities in many industrial and chemical processes. Lithium-ion batteries are also widely used in mobile devices, which are universally accepted today. “I’m always surprised that the public never talks about lithium in laptops or mobile phones – but suddenly it’s a problem with the e-car,” the battery researcher said. 

But the water consumption involved in the production of lithium for electric car batteries is just the tip of the iceberg. Fichtner estimates that a 64 kWh pack is likely in the middle of various variants of the Tesla Model 3 sedan, whose long-range versions can easily go beyond 450 km (280 miles) of range per charge. If one were to infer that an electric car battery pack can remain optimal with 2,000 full charging cycles, this could equate to a total distance of about 900,000 km. And that’s with estimates on existing battery technology. 

With this in mind, it appears that Tesla’s lithium-ion batteries are actually less polluting than otherwise everyday items such as steak or the aforementioned 30 cups of coffee, since they have the potential to remain in service for a very long time. About 2,000 charging cycles, after all, would likely equate to years of average EV use.

Companies like Tesla are hard at work in improving their battery cells. This much is hinted at by Tesla executives such as CEO Elon Musk and President of Automotive Jerome Guillen, both of whom have noted that Tesla’s batteries are always evolving. Fichtner expects electric car batteries to have an average lifespan of 3,000 cycles by 2025, which would make EV batteries even more environmentally-friendly. 

In his recent conversation with the publication, the researcher discussed one of the most sensitive topics surrounding battery production: cobalt. Cobalt has developed a very negative reputation due to the abhorrent conditions in cobalt mines in areas such as Congo. Fortunately, many automakers have since pledged to source the cobalt used in their EVs from areas that meet stringent standards. Tesla does this and more, with the electric car maker attempting to develop cobalt-free batteries in the near future. 

For now, electric car makers are in a game of cobalt reduction, and in this sense, Tesla has a notable lead. The batteries used in Volkswagen’s well-received ID.3 hatchback, for example, contain about 12-14% cobalt. The Tesla Model 3, on the other hand, only contains about 2.9% cobalt as of 2018. Fichtner predicts that if things go well, cobalt-free batteries could enter the market as early as 2025. 

Maximilian Fichtner received his Ph.D. in Chemistry/Surface Science with distinction and the Hermann Billing Award for his thesis in 1992. He currently serves as the professor for Solid State Chemistry at the Ulm University and Executive Director of the Helmholtz Institute Ulm for Electrochemical Energy Storage (HIU). He has also worked in collaboration with the German ministries of Economy and Research and Education, and has served as the Chair of the 1st International Symposium on Magnesium Batteries in 2016.

The Taycan is one of Porsche’s biggest announcements in recent years, and the company’s first crack at an all-electric performance car recently received top marks in terms of crash-test safety ratings from the European New Car Assessment Programme (Euro NCAP). The announcement comes shortly after news that the Tesla Model X was given the same 5-stars with a stellar 98 rating on adult occupant safety.  The tests for the Taycan were performed in December 2019.

Euro NCAP noted that Taycan’s safety score, while only performed on the 4s variant of the Taycan, would apply to the 4s Plus, the Turbo, and Turbo S trims.

In terms of the Adult Occupant, Euro NCAP noted: “The passenger compartment of the Taycan remained stable in the frontal offset test. Dummy readings indicated good protection of the knees and femurs of the driver and passenger. Porsche showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions. In the full-width rigid barrier test, protection of all critical body areas was good or adequate for both occupants, with the exception of the rear passenger’s chest, for which dummy readings of compression indicated a marginal level of protection.

“In the side barrier impact, protection of all critical body areas was good and the car scored full points in this tests. In the more severe side pole test, protection of the chest was adequate and that of other body areas was good. Tests on the front seats and head restraints demonstrated marginal protection against whiplash injuries in the event of a rear-end collision. A geometric assessment of the rear seats also indicated marginal whiplash protection. The standard-fit autonomous emergency braking (AEB) system performed well in tests of its functionality at the low speeds at which many whiplash injuries occur. However, the Taycan was not awarded the points for these tests as good dynamic performance in the front seats is a prerequisite for AEB scoring.”

In the past, Porsche’s vehicles have received positive ratings from Euro NCAP. In 2014, the Porsche Maycan received a five-star rating, and in 2017, the Cayenne received the same top score. Quite interestingly, the Porsche Taycan’s 5-star rating also matches the stellar scores earned by the Model 3, Tesla’s more affordable sedan.

The Taycan was unveiled by the German automaker in early September in three simultaneous events in Canada, Germany, and China. Porsche’s first attempt at an electric sports car was introduced at the Toronto, Canada event by Porsche Executive Board Member for Sales and Marketing Detlev von Platen, who was adamant that the Taycan would help the automaker transition into the electric vehicle market. “The Taycan links our heritage to the future. It carries forward the success story of our brand – a brand that has fascinated and thrilled people the world over for more than 70 years. This day marks the start of a new era,” von Platen said.

A New York man plans to use the Tesla Cybertruck as a power source for his “tiny home.” Karl Gesslein, a resident of Ithaca placed an order for the Cybertruck the day of the unveiling after realizing that Tesla’s initial attempt at a pickup truck was exactly what he had been looking for since his childhood.

The idea came from his desire to power his new house in a sustainable way, and by using the $50,000 Dual Motor variant of the Tesla Cybertruck, he will no longer need to use portable batteries as his primary power source.

“I watched the Cybertruck reveal and knew I had to have one because it was everything I had always wanted in a car but never been able to have,” Gesslein said. His interest in the Cybertruck came from his childhood dreams of owning cars like the Lotus Espirit and the Delorian DMC-12. But the most appealing thing about the vehicle was its capability to power his house, especially with the help of the “Vault’s” optional solar panel cover.

Currently, Gasslein and his wife live in an off-the-grid house that they have called home for six years. The house utilizes a homemade battery pack, but he is looking for another option as only 1 kWh of the 1.25 kWh system is usable. The Cybertruck, by his estimation, would power his home for 240 straight days, along with some help from solar panels. “That is long enough to get through a pretty harsh nuclear winter with some time to spare,” he says in a blog post he wrote about his idea.

One thing that Gesslein has noted is that the Cybertruck would fight power outages and scheduled blackouts, especially if the vehicle was hooked up to an on-the-grid circuit breaker. Blackouts and power outages are a relevant issue, especially to those who live in California’s San Francisco Bay Area, who were negatively impacted by them earlier this year.

Pacific Gas and Electric (PG&E), a power supplier for many Bay Area homes, conducted mandatory scheduled blackouts to lower the possibility of forest fires caused by their powerlines during California’s windy and dry Autumn months. In response to the blackouts, Tesla offered its solar solutions for a reduced cost, a strategy that would assist homeowners in avoiding blackouts and carbon emissions altogether.

Tesla’s Cybertruck is a versatile machine. Its triple-motor setup offers the highest towing capacity on the market with a 14,000+ lb rating, a stainless steel design that will not bend or dent, a solar panel vault cover capable of charging the vehicle while it is sitting in sunlight, and a charging port for the electric ATV Tesla unveiled at the same event.

But now, the truck will have a new use: powering a future owner’s tiny home. The Cybertruck is a safe and sustainable option for those who are looking for an alternative way to power their homes. While it will take some creativity and some experience with electric, it is definitely possible. “The Cybertruck is the best deal to be found for electric backup power that won’t accidentally burn your house to the ground or kill you in your sleep. Hands down,” Gesslein said.

The Cybertruck begins production in late-2021 and has accumulated over a quarter-of-a-million pre-orders according to CEO Elon Musk. The truck will be available in three trims, a Single, Dual, and Tri-Motor, all offering different power and performance ratings. The Single Motor base model will cost $39,900, the Dual Motor $49,990, and the Tri-Motor variant that will offer a 2.9 second 0-60 MPH acceleration rate will be available for $69,900.

SpaceX will aim to send a Dragon cargo capsule to the International Space Station aboard its 19th Commercial Resupply Services (CRS-19) contract mission for NASA. Currently, NASA and SpaceX are targeting a 12:51 pm EST launch time this Wednesday afternoon, December 4th from Space Launch Complex 40 at Cape Canaveral Air Force Station in FL.

The mission will feature a previously flown Dragon capsule (C106) that has visited the ISS not once, but twice. It previously completed SpaceX’s fourth and eleventh Commercial Resupply contract missions to the ISS in 2014 and 2017 respectively. The CRS-19 mission is only the second mission to feature a twice flown Dragon capsule to visit for a third time. It will join the only thrice flown C108 Dragon capsule that recently completed the CRS-18 mission this past July.

The C106 Dragon capsule is currently filled with over 5,700lbs of cargo and supplies including more than 250 science investigations and technology demonstrations. Investigations include malting barley seeds while in a microgravity environment and Rodent Research-19 to investigate methods of preventing bone and muscle loss.

Along with a recycled Dragon capsule, the CRS-19 mission will feature a freshly minted Falcon 9 core (B1059.1). This is notable as re-flown Falcon 9 boosters have almost become the norm for SpaceX launches. B1059.1 is the first fresh Falcon 9 core to be flown since the STP-2 Falcon Heavy in June of 2019. The booster is expected to return for landing aboard the autonomous spaceport droneship Of Course I Still Love You.

SpaceX and NASA will both provide webcast of today’s mission. The SpaceX webcast will go live about 15 minutes prior to today’s launch time of 12:51pm EST provided below.

SpaceX’s CRS-19 Falcon 9 launch and landing has been scrubbed by wind conditions miles above the ground at the same time as the rocket’s drone ship landing platform battles high seas in the Atlantic Ocean.

SpaceX decided to stand down from Wednesday’s launch attempt for NASA’s CRS-19 International Space Station (ISS) resupply mission due to unacceptably high upper-level winds. Previously scheduled to lift off around 12:51 pm ET (16:51 UTC) on December 4th, NASA and SpaceX have recycled the mission and are now targeting 12:29 pm ET (16:29 UTC) on December 5th, slightly different to account for the ever-changing position of the ISS.

In rocketry, upper-level winds have always been a bit of a problem: different air currents at different altitudes can produce an effect akin to running sideways along a series of treadmills, dramatically increasing the risk of a rocket’s structure failing under longitudinal loads. At the same time, drone ship Of Course I Still Love You – set to recover Falcon 9 booster B1059 shortly after its launch debut – is dealing with high seas in the Atlantic Ocean, raising the risk of the booster suffering damage during landing or even toppling off the deck.

CRS-19 features a flight-proven Cargo Dragon capsule (C106) that has visited the ISS not once, but twice. It previously completed SpaceX’s fourth and eleventh Commercial Resupply contract missions in 2014 and 2017 and will be the second time a twice-flown Dragon capsule heads to orbit for the third time. After berthing at the ISS around December 8th (assuming a Thursday launch), Dragon will depart the ISS and land in the Pacific Ocean sometime in early January, about a month after arriving at the station.

Along with a recycled Dragon capsule, the CRS-19 mission will feature a fresh-from-the-factory Falcon 9 booster – in this case, B1059.1. New Falcon 9 boosters have become a rarity in 2019, and this mission’s only flight-proven hardware will actually be the orbital spacecraft, Cargo Dragon.

B1059.1 is the first fresh Falcon 9 core to be flown since the STP-2 Falcon Heavy in June of 2019. The booster is expected to return for landing aboard the autonomous spaceport droneship Of Course I Still Love You.

Science On Board

Waiting patiently atop Falcon 9, Cargo Dragon is loaded with almost 5800 pounds (2650 kg) of cargo, including more than 250 science investigations and technology demonstrations to be performed on the ISS. Investigations include a look into the process of malting barley seeds (i.e. beer) in a microgravity environment to hopefully improve the process on Earth and explore possible nutritional use for future long-duration space missions.

Another prominent investigation – Rodent Research-19 or “Mighty Mice in Space” – is sending live mice to the ISS to investigate a preventative measure to prevent muscle and bone loss caused by long-term microgravity exposure, potentially aiding astronauts on long-duration space missions. According to NASA, “this therapeutic approach may be optimal in conditions characterized by both muscle and bone loss. Hence, this therapeutic strategy may have significant advantages for certain applications, including treatment of muscle and bone loss during spaceflight.”

SpaceX will provide a webcast of the launch attempt that will go live about 15 minutes prior to liftoff, NET 12:29 pm ET (16:29 UTC), December 5th.
