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 reveals it is using AI to make factories more sustainable: here’s how

Tesla is using AI in its Gigafactory Nevada factory to improve HVAC efficiency.

Tesla has revealed in its Extended Impact Report for 2024 that it is using Artificial Intelligence (AI) to enable its factories to be more sustainable. One example it used was its achievement of managing “the majority of the HVAC infrastructure at Gigafactory Nevada is now AI-controlled” last year.

In a commitment to becoming more efficient and making its production as eco-friendly as possible, Tesla has been working for years to find solutions to reduce energy consumption in its factories.

For example, in 2023, Tesla implemented optimization controls in the plastics and paint shops located at Gigafactory Texas, which increased the efficiency of natural gas consumption. Tesla plans to phase out natural gas use across its factories eventually, but for now, it prioritizes work to reduce emissions from that energy source specifically.

It also uses Hygrometric Control Logic for Air Handling Units at Giafactory Berlin, resulting in 17,000 MWh in energy savings each year. At Gigafactory Nevada, Tesla saves 9.5 GWh of energy through the use of N-Methylpyrrolidone refineries when extracting critical raw material.

Perhaps the most interesting way Tesla is conserving energy is through the use of AI at Gigafactory Nevada, as it describes its use of AI to reduce energy demand:

“In 2023, AI Control for HVAC was expanded from Nevada and Texas to now include our Berlin-Brandenburg and Fremont factories. AI Control policy enables HVAC systems within each factory to work together to process sensor data, model factory dynamics, and apply control actions that safely minimize the energy required to support production. In 2024, this system achieved two milestones: the majority of HVAC infrastructure at Gigafactory Nevada is now AI-controlled, reducing fan and thermal energy demand; and the AI algorithm was extended to manage entire chiller plants, creating a closed-loop control system that optimizes both chilled water consumption and the energy required for its generation, all while maintaining factory conditions.”

Tesla utilizes AI Control “primarily on systems that heat or cool critical factory production spaces and equipment.” AI Control communicates with the preexisting standard control logic of each system, and any issues can be resolved by quickly reverting back to standard control. There were none in 2024.

Tesla says that it is utilizing AI to drive impact at its factories, and it has proven to be a valuable tool in reducing energy consumption at one of its facilities.

Tesla analysts believe Musk and Trump feud will pass

Tesla CEO Elon Musk and U.S. President Donald Trump’s feud shall pass, several bulls say.

Tesla analysts are breaking down the current feud between CEO Elon Musk and U.S. President Donald Trump, as the two continue to disagree on the “Big Beautiful Bill” and its impact on the country’s national debt.

Musk, who headed the Department of Government Efficiency (DOGE) under the Trump Administration, left his post in May. Soon thereafter, he and President Trump entered a very public and verbal disagreement, where things turned sour. They reconciled to an extent, and things seemed to be in the past.

However, the second disagreement between the two started on Monday, as Musk continued to push back on the “Big Beautiful Bill” that the Trump administration is attempting to sign into law. It would, by Musk’s estimation, increase spending and reverse the work DOGE did to trim the deficit.

President Trump has hinted that DOGE could be “the monster” that “eats Elon,” threatening to end the subsidies that SpaceX and Tesla receive. Musk has not been opposed to ending government subsidies for companies, including his own, as long as they are all abolished.

How Tesla could benefit from the ‘Big Beautiful Bill’ that axes EV subsidies

Despite this contentious back-and-forth between the two, analysts are sharing their opinions now, and a few of the more bullish Tesla observers are convinced that this feud will pass, Trump and Musk will resolve their differences as they have before, and things will return to normal.

ARK Invest’s Cathie Wood said this morning that the feud between Musk and Trump is another example of “this too shall pass:”

Additionally, Wedbush’s Dan Ives, in a note to investors this morning, said that the situation “will settle:”

“We believe this situation will settle and at the end of the day Musk needs Trump and Trump needs Musk given the AI Arms Race going on between the US and China. The jabs between Musk and Trump will continue as the Budget rolls through Congress but Tesla investors want Musk to focus on driving Tesla and stop this political angle…which has turned into a life of its own in a roller coaster ride since the November elections.”

Tesla shares are down about 5 percent at 3:10 p.m. on the East Coast.

Tesla scrambles after Musk sidekick exit, CEO takes over sales

Tesla CEO Elon Musk is reportedly overseeing sales in North America and Europe, Bloomberg reports.

Tesla scrambled its executives around following the exit of CEO Elon Musk’s sidekick last week, Omead Afshar. Afshar was relieved of his duties as Head of Sales for both North America and Europe.

Bloomberg is reporting that Musk is now overseeing both regions for sales, according to sources familiar with the matter. Afshar left the company last week, likely due to slow sales in both markets, ending a seven-year term with the electric automaker.

Tesla’s Omead Afshar, known as Elon Musk’s right-hand man, leaves company: reports

Afshar was promoted to the role late last year as Musk was becoming more involved in the road to the White House with President Donald Trump.

Afshar, whose LinkedIn account stated he was working within the “Office of the CEO,” was known as Musk’s right-hand man for years.

Additionally, Tom Zhu, currently the Senior Vice President of Automotive at Tesla, will oversee sales in Asia, according to the report.

It is a scramble by Tesla to get the company’s proven executives over the pain points the automaker has found halfway through the year. Sales are looking to be close to the 1.8 million vehicles the company delivered in both of the past two years.

Tesla is pivoting to pay more attention to the struggling automotive sales that it has felt over the past six months. Although it is still performing well and is the best-selling EV maker by a long way, it is struggling to find growth despite redesigning its vehicles and launching new tech and improvements within them.

The company is also looking to focus more on its deployment of autonomous tech, especially as it recently launched its Robotaxi platform in Austin just over a week ago.

However, while this is the long-term catalyst for Tesla, sales still need some work, and it appears the company’s strategy is to put its biggest guns on its biggest problems.
