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.
Tesla (NASDAQ: TSLA) is set to hold its Earnings Call for the first quarter of 2026 on Wednesday, and there are a lot of interesting things that are swirling around in terms of speculation from investors.
With the company’s executives, including CEO Elon Musk, answering a handful of questions that investors submit through the Say platform, fans want to know a lot of things about a lot of things.
These five questions come from Retail Investors, who are normal, everyday shareholders:
- When will we have the Optimus v3 reveal? When will Optimus production start, since we ended the Model S and Model X production earlier than mid-year? What’s the expected Optimus production rate exiting this year? What are the initial targeted skills?
- What milestones are you targeting for unsupervised FSD and Robotaxi expansion beyond Austin this year, and how will that drive recurring revenue?
- How will Hardware 3 cars reach Unsupervised Full Self-Driving?
- When do you expect Unsupervised Full Self-Driving to reach customer cars?
- When will Robotaxi expand past its current limited rollout?
Additionally, these are currently the three questions that are slated to be answered by Institutional Firms, which also answer a handful of questions during the call:
- Now that FSD has been approved in the Netherlands and is expected to launch across Europe this summer, can you discuss your Robotaxi strategy for the region?
- What enabled you to finish the AI5 tapeout early and were there any changes to the original vision? Last week, Elon said AI5 will go into Optimus and the Supercomputer, but one month ago said it would go into the Robotaxi. Has AI5 been dropped from the vehicle roadmap?
- Given the recent NHTSA incident filings, can you update us on the Robotaxi safety data? If safety validation remains the primary bottleneck, why not deploy thousands of vehicles to accelerate the removal of the safety driver?
The questions range through every current Tesla project, including FSD expansion and Optimus. However, many of the answers we will get will likely be repetitive answers we’ve heard in the past.
This is especially pertinent when the questions about when Unsupervised FSD will reach customer cars: we know Musk will say that it will happen this year. Is Tesla capable of that? Maybe. But a more transparent answer that is more revealing of a true timeline would be appreciated.
Hardware 3 owners are anxiously awaiting the arrival of FSD v14 Lite, which was promised to them last year for a release sometime this year.
The Earnings Call is set to take place on Wednesday at market close.

Elon Musk reveals shocking Tesla Optimus patent detail
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
Elon Musk revealed a shocking detail on the Tesla Optimus patent that was revealed last week. Despite it being made public for the first time, Musk said the company has already moved on from the design, an incredible truth about the development of new technology: things move fast.
Musk dropped a bombshell about the Tesla Optimus humanoid robot hand patent that was released last week. Musk, candidly replying to a post late at night on X, revealed that what is a new technology to many fans and insiders is actually old news to those developing the tech directly.
“We already changed the design,” Musk said. “This one didn’t actually work.”
We already changed the design. This one didn’t actually work.

Patents, after all, are often viewed as blueprints for future products. Yet Musk revealed that the rolling contact mechanism—intended to provide smooth, low-friction articulation in the fingers—had already been scrapped after real-world testing exposed its shortcomings.
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
The hand has been one of the biggest challenges for Tesla engineers since Optimus development started years ago. Musk has said that there is not enough recognition for how incredible and useful the human hand is, and designing one for a humanoid robot has been the biggest challenge of all.
Tesla is stumped on how to engineer this Optimus part, but they’re close
This moment underscores the persistent engineering hurdles in achieving reliable humanoid hand dexterity. Human fingers are marvels of evolution: 27 bones, intricate tendons, ligaments, and a network of sensors working in perfect harmony. Replicating that in metal and silicon is extraordinarily difficult.
Rolling contacts promised reduced wear and precise motion, but testing likely revealed issues with durability under repeated stress, grip stability on varied surfaces, or the micro-precision needed for fine motor skills.
These aren’t minor tweaks, but instead they represent fundamental challenges that have plagued robotics teams for decades. Even advanced competitors struggle here—hands remain the Achilles’ heel of most humanoids because the margin for error is razor-thin.
A fraction of a millimeter off, and a robot drops a glass or fails to button a shirt.
What makes Musk’s reply remarkable is how it signals Tesla’s direct communication style on prototype limitations. While many companies guard failures behind glossy marketing and vague timelines, Tesla openly shares setbacks.
Musk was forthcoming about the failure of this recent design. This transparency builds trust with investors, engineers, and fans. It shows Tesla treats Optimus development like true science: rapid iteration, rigorous testing, and zero tolerance for hype that doesn’t match reality.
The disclosure from Musk also highlights Tesla’s blistering pace of development. By the time the patents are published, which is often over a year after the initial filing, the technology has already evolved.
Optimus is far from a static product, and it’s a living project advancing weekly.
In the high-stakes race for general-purpose robots, Tesla’s approach stands out. Admitting a finger-joint design “didn’t actually work” isn’t a weakness—it’s confidence.
True innovation demands confronting failure head-on, and Musk just reminded the world that Optimus is being engineered that way. The next version of those hands is already in testing, and it will be better because Tesla isn’t afraid to say what didn’t work.

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.
