Elon Musk is trying to help solve the Flint Water Crisis
After building a mini-submarine to aid in the rescue attempt of the members of the Wild Boar soccer team in Thailand, Elon Musk is now flexing his philanthropic muscles towards a long-standing issue in the United States — the Flint Water Crisis.
Musk previously noted on Twitter that he has already been helping out the citizens of Flint. Spurred on by some Flint residents and activists for the city, however, Musk opted to take a more hands-on approach. The Tesla and SpaceX CEO promptly coordinated with individuals testing the contamination levels of the city’s water system, and by Wednesday, Musk has provided an email address, flint@x.com, where residents can send the results of their water’s ppm (parts per million) and ppb (parts per billion) levels.
Musk’s pledge to help the people of Flint has mostly been met positively by the online community, with several of his followers even offering to lend a hand to a “barnstorming weekend” aimed at installing water filters in the homes of the city’s residents. Musk also reacted favorably to the idea of utilizing Flint’s local plumbers to help in the initiative. Despite being in China to discuss Tesla’s plans of building Gigafactory 3 in Shanghai, Musk further stated that he would call Flint Mayor Karen Weaver about plans to address the city’s water problems.
Gathering input this week, will begin taking action next week and let people know how they can help

Just like his efforts to help in the Thailand cave rescue operations, Musk’s pledge to help the city of Flint became a target for his staunch critics online. Key Flint activist Mari Copeny, better known as Little Miss Flint due to her letter to then-president Barack Obama about the ongoing water crisis, clarified Musk’s involvement, however, stating that the city is appreciative of the serial tech entrepreneur’s efforts to help.
Hey world. Let’s set the record straight. My team has been working with @elonmusk and his team for over a week to figure out the best solution to help #Flint with the #FlintwaterCrisis
Extremely grateful for him and all he has done so far.— Mari Copeny (@LittleMissFlint) July 12, 2018
The Flint Water Crisis started in April 2014, after the city’s drinking water source was changed from Lake Huron and the Detroit River to the much cheaper Flint River. Insufficient water treatment caused lead to be leached from lead water pipes into the residents’ drinking water. Lead pipes are viable pipes for water systems, provided that corrosion inhibitors are used to prevent lead from contaminating the water. A common corrosion inhibitor is orthophosphate, which forms low-solubility complexes with the lead in the pipes. Orthophosphates were used in Flint’s systems when the drinking water was coming from Detroit, but when the shift to the Flint River was conducted, no orthophosphate or any other anti-corrosion inhibitors were used. The absence of these inhibitors is behind the harrowing images of rust-colored water coming from Flint’s water supply.
The lead-contaminated water caused several grave problems for Flint’s residents. Between 6,000 to 12,000 children from Flint have been exposed to drinking water with high levels of lead, which could result to serious health problems. The percentage of Flint children with elevated blood-lead levels is estimated to have risen from about 2.5% in 2013 to as much as 5% in 2015 as well. An outbreak of Legionnaires’ Disease, a form of atypical pneumonia with no known vaccine, also resulted in 10 fatalities. The Legionnaires’ outbreak is linked to Flint’s contaminated water supply.

The Flint Water Crisis has resulted in several lawsuits being filed against government officials, many of which were accused of mismanaging the situation. Since the water crisis’ peak, however, the Michigan Department of Environmental Quality (MDEQ) has stated that the lead content of Flint’s water has fallen below the federal limit. As of April 2018, the MDEQ issued a statement assuring Flint’s residents that the city’s water quality “has been restored.” Regardless of this, however, many Flint residents remain skeptical that their water is now safe, especially considering that the replacement of the contaminated lead pipes is still ongoing. In this sense, Musk noted on Twitter that the planned “barnstorming” weekend in Flint would not only aim to give residents water filters for their homes; it would also attempt to fix residents’ perception of the city’s water supply.
You’re right on both counts. Most houses in Flint have safe water, but they’ve lost faith in govt test results. Some houses are still outliers. Will organize a weekend in Flint to add filters to those houses with issues & hopefully fix perception of those that are actually good.

While Elon Musk’s recent philanthropic ventures are attracting more attention than usual, the SpaceX and Tesla CEO’s humanitarian efforts have actually been going on for some time. It should be noted that Tesla’s big battery in South Australia was started after Musk became aware of the power crisis in the region. After Hurricane Maria ravaged Puerto Rico, Musk also promptly sent a team to help the island nation get back on its feet. As of Musk’s latest update, he noted that there are currently 11,000 projects underway in Puerto Rico.
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
