Almost five months after SpaceX began the process of filling and testing the first custom-built propellant storage system for Starship, the largest rocket ever built, the company has finally begun to fill the fuel half of the ‘tank farm’.

SpaceX began delivering truckloads of liquid nitrogen (LN2) to the LN2 and liquid oxygen (LOx) sections of the tank farm in mid-September 2021, well before the farm was anywhere close to completion. In about a month, SpaceX accepted ~60 LN2 deliveries – enough to partially fill one of the farm’s seven cryogenic tanks. Instead of some operational purpose, that LN2 was likely used to clean and partially proof the farm’s three LOx tanks. Just two weeks later, the orbital tank farm received its first LOx deliveries.

At the time, mere days after the basic structure of the main tank farm storage system was effectively completed, most figured that it would take SpaceX about as long to clean, proof, and begin filling the farm’s two liquid methane tanks. That would not be the case.

SpaceX installed the second of the farm’s two vertical SpaceX-built cryogenic liquid methane (LCH4) tanks in mid-October 2021. All seven cryogenic tanks had ‘sleeves’ – designed to be filled with foam insulation – installed by the end of the month, effectively completing the farm’s basic structure half a year after assembly began. However, around the same time, SpaceX also installed two horizontal tanks that were also identified as LCH4 storage – giving the overall tank farm far more fuel storage than its oxidizer (LOx) tanks could match. Starship’s Raptor engines burn about 3.55 kilograms of LOx for every 1 kilogram of LCH4.

As work on the vertical LCH4 tanks appeared to slow to a crawl, it took until December 2021 for SpaceX to begin cleaning and proofing the farm’s horizontal LCH4 tanks with liquid nitrogen. By that time, a rough unofficial narrative had been constructed to explain the lack of progress on the farm’s fuel half. Namely, in an excellent Twitter thread, CSI Starbase made a strong case that SpaceX appeared to have designed the first orbital-class Starship tank farm – a compact and pleasingly symmetric set of eight vertical storage tanks – without taking into consideration rudimentary Texas regulations for the storage of liquid natural gas and methane. By all appearances, that conclusion was correct, as the farm was visibly violating several rules – namely the requirements that all LCH4 storage be surrounded by six-foot-tall retaining walls and that all associated plumbing not be situated under power cabling.

As it exists, the LCH4 side of the vertical tank farm violates both of those rules and it’s not obvious that there is actually enough space between the two vertical methane tanks to build a retaining wall with two feet of horizontal clearance. It’s possible that the situation is more complex and that SpaceX intentionally broke those rules or was pursuing an exception to them but the end result was that those vertical LCH4 tanks have yet to be finished, let alone cleaned or proof tested. Instead, SpaceX appears to have fully refocused on horizontal tanks and most recently tore down a dirt berm beside them and began preparing foundations for at least two or three more.

Those horizontal tanks appear to store about 1000 cubic meters (~35,000 ft^3) of LCH4, while the vertical tanks would have stored about 1800 m^3. To fully replace them, SpaceX will need approximately four horizontal tanks – two more in addition to the two already installed. Thankfully, SpaceX has finally begun filling the already installed tanks while it works to expand the methane farm, beginning with three truckloads on the very first day – February 13th, 2022.

To fill the two existing tanks, which may store enough methane to fuel a stacked Starship and Super Heavy about 4/5ths of the way, SpaceX will need around 40-50 more tanker deliveries. Since last November, SpaceX has completed more than 320 liquid nitrogen and 200 liquid oxygen deliveries – equivalent to about 6700 tons (~14.8M lb) of LN2 and 4200 tons (~9.3M lb) of LOx. If SpaceX maintains that average and focuses entirely on LCH4, the two horizontal tanks could be filled to the brim before the end of February.

Having a substantial amount of LCH4 stored at the orbital tank farm will finally allow SpaceX to attempt the first major wet dress rehearsals (WDRs) and, more importantly, the first full static fires with flightworthy Super Heavy booster prototypes. Of course, a tank farm with full supplies of LOx, LCH4, LN2, and their gaseous equivalents is also a necessity for the first orbital Starship launch attempt, which has most recently slipped from a target of mid-2021 to no earlier than (NET) Q2 2022, pending regulatory approval.

Tesla Robotaxi is headed to New York City, but one thing is in its way

Tesla is working to hire Vehicle Operators in New York City, but the company still needs some regulatory hurdles to go through.

Tesla Robotaxi will be headed to New York City, but there is one huge thing that stands in its way: approval to test autonomous vehicles.

Tesla is expanding its Robotaxi platform across the United States as it currently operates in Austin, Texas, and the Bay Area of California.

The company has also been seeking approvals in several other states, including Nevada, Arizona, and Florida.

However, the company is also working to expand to major metropolitan areas across the U.S. that it has not explicitly mentioned, as it attempts to reach CEO Elon Musk’s goal of giving half of the country’s population access to the platform by the end of the year:

It appears New York City is next on the list, according to a job posting on Tesla’s Careers website.

The company says it is hiring a Vehicle Operator for Autopilot in Flushing, New York, a section of the borough of Queens. Queens is connected to Brooklyn and Long Island, so it seems more ideal than launching in Manhattan or the Bronx, where traffic is heavy and charging is not as readily available.

Tesla’s job posting states:

“We are looking for a highly motivated self-starter to join our vehicle data collection team. As a Prototype Vehicle Operator, you will be responsible for driving an engineering vehicle for extended periods, conducting dynamic audio and camera data collection for testing and training purposes. Access to the data collected is limited to the applicable development team. This role requires a high level of flexibility, strong attention to detail, excellent driving skills, and the ability to thrive in a fast-paced, dynamic environment.”

It also lists the hours of operation as Tuesday through Saturday or Sunday through Thursday, with its three shifts listed as:

  • Day Shift: 6:00 AM – 2:30 PM or 8:00 AM – 4:30 PM
  • Afternoon Shift: 2:00 PM – 10:30 PM or 4:00 PM – 12:30 AM
  • Night Shift: 10:00 PM-6:30 AM or 12:00 AM-8:30 AM

We wouldn’t count on New York City being the next place Tesla launches Robotaxi. According to a report from CNBC, a spokesperson for the NYC Department of Transportation confirmed Tesla has not yet applied for permits that are needed to operate its ride-hailing service.

For what it’s worth, it could just be the first step in Tesla’s plans. It also has Vehicle Operator job postings in other regions. Houston, Texas, as well as Tampa, Miami, and Clermont, Florida, are all listed on Tesla’s Career postings.

Tesla’s Elon Musk gives nod to Ford while acknowledging his influence on EVs

“Ford basically invented mass manufacturing of large, complex products. Everyone else copied.”

Tesla CEO Elon Musk gave a tremendous nod to Ford while also acknowledging his own influence on EVs and the automotive industry in general.

Yesterday, Ford announced its new manufacturing process for EVs, which was essentially a rebirth of its own production lines and plans for more affordable models to offer consumers.

It was important to recognize that Ford truly launched automotive manufacturing with its production of the Model T 122 years ago.

That’s exactly what Musk did in a response to Ford CEO Jim Farley:

In the over 100 years since Ford started producing vehicles, the company has had one significant fact go under the radar: it truly created a great process for building large, complex vehicles. It is something that many companies eventually adopted as the car industry took off.

Tesla is in a similar situation. It has used things like the Giga Press from the Italian company IDRA to create a better, more efficient, streamlined process for building cars.

It was able to use casting to eliminate a vast majority of parts from the Model Y, which not only helped increase manufacturing efficiency but also improved safety and structural rigidity. It truly revolutionized manufacturing for the company, and Ford said that it would adopt a similar mindset with its new EVs.

Yesterday, Doug Field, the Chief EV, Digital and Design Officer for Ford, and a former Sr. VP of Engineering for Tesla, said the company was taking the mentality that “the best part is no part.”

Musk acknowledged how far it has come and how it is influencing other car companies to do the same in terms of its production strategy:

Ford is using an “Assembly Tree,” which is essentially very similar to Tesla’s “unboxed production process.” In addition to the use of Gigacasting, which Ford is calling “Unicasting,” as well as the use of structural batteries, it is almost as if Tesla is having its own “Model T moment.”

Ford has been quick to adopt an EV mentality as it plans to transition its business over the next decades. It is working to prepare for the future of the atuomotive industry, and although it has adjusted its strategy, it can’t be denied that Ford is one of the legacy automakers taking this new chapter in cars seriously.

Tesla has one big bottleneck with its public Robotaxi launch, but it can fix it easily

Elon Musk plans for Tesla Robotaxi to be open to the public in Austin in September.

Tesla CEO Elon Musk said that the company’s Robotaxi program would open to the public in September, but there is one big bottleneck that would inhibit it from launching smoothly.

The thing is, it can be resolved in no time, and Tesla can fix it internally.

In Austin, the Robotaxi platform has been in operation since late June. The launch of the program only allowed a handful of privileged influencers and groups to access the driverless ride-hailing service, although it has expanded this group on several occasions.

It has also slowly added vehicles to the fleet, starting at 11 cars when it launched in June. There have been a few cars added, but Tesla has continued to prioritize safety, keeping its rider population and number of vehicles low for the time being.

However, this is going to cause quite a bit of a bottleneck in next month’s planned public launch, as there will be an open invitation for anyone and everyone to test out the Robotaxi platform in Austin.

Tesla CEO Elon Musk confirms Robotaxi is opening to the public: here’s when

Many people have been waiting for an invitation to ride in a Robotaxi, and Tesla has not been prone to give one to just anybody.

As that becomes a much larger number next month, Tesla is going to have to step up its Robotaxi fleet number, as well as its population of Safety Monitors, the riders that sit in the passenger seat to ensure everything goes smoothly.

While the geofence in Austin has roughly doubled in size twice during both of Tesla’s expansions of the service area, the company is still playing it safe with rider population growth, something that aligns with its focus on safety.

Musk said recently about the expansion of Robotaxi to customer-owned vehicles:

“As I said, we’re being paranoid about safety. But I guess next year is I’d say confidently next year. I’m not sure when next year, but confidently next year, people would be able to add or subtract their car to the Tesla, Inc. fleet.”

The Robotaxi fleet will, without a doubt, revolutionize the way people view ride-hailing. Tesla seems ready to open it up to the public next month, based on what Musk said, but some changes will have to occur to ensure it goes smoothly.
