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 shows what Roadster drivers will see on screen before thruster activation
Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.
Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”
The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.
Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.
That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.
The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.
The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.
Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves
Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.
Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”
The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.
Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.
The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.
Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.
The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.
Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on
Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.
Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.
On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”
Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”
The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.
Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.
How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.
Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.
Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.
