The Dirty Environmental Tricks of Elon Musk

Elon Musk made big promises to Wall Street about Tesla’s Model Y SUV in 2022, and the company was ramping up its production in Austin, Texas, when environmental problems threatened to derail his plans. The door to the plant’s giant casting furnace, which melts metal to be molded into the Model Y’s parts, wouldn’t shut, spewing toxins into the air and raising temperatures for workers on the floor to as high as 100 degrees. Hazardous wastewater from production—containing paint, oil and other chemicals—was also flowing untreated into the city’s sewer, in violation of state guidelines. Tesla left the costly problems largely unaddressed during the critical ramp-up. As a result, the company’s 10 million-plus square foot plant—among the largest car factories in the world—dumped toxic pollutants into the environment near Austin for months.

This account of the Austin plant’s environmental problems, which haven’t been reported previously, comes from emails between Texas regulators and the company obtained by The Wall Street Journal in response to public-records requests, as well as interviews with former employees and other documents, including a memo sent by a whistleblower to the Environmental Protection Agency….Former employees said they feared they might lose their job if they drew attention internally to potential environmental hazards, because senior managers didn’t consider such issues to be mission critical. As head of the company, Musk set the tone, these people said, pushing employees to move fast and complaining frequently in public statements that unnecessary regulations are strangling the U.S.

Musk is considered a champion of the environment for his role in pioneering the electric car industry. He has said the mission of Tesla, which is the largest maker of electric cars in the U.S., is to “protect life on Earth.” Yet across his business empire, Musk’s companies show a pattern of breaking environmental rules again and again, federal and state government filings and documents show.

Tesla’s Fremont, Calif., facility has accumulated more warnings for violations of air pollution rules over the past five years than almost any other company’s plant in California, according to a Journal analysis of informal enforcement actions in the EPA’s compliance database. It is second only to a refinery owned by oil-and-gas behemoth Chevron, which is in nearby Richmond.

In 2024, California regulators said Tesla violated air-pollution permits at its Fremont factory 112 times over the past five years and alleged it repeatedly failed to fix equipment designed to reduce emissions, releasing thousands of pounds of toxic chemicals in excess of permissible limits into the surrounding communities.

Musk’s rocket company, SpaceX, has also had run-ins with regulators in Texas and community pushback in Florida, including over the impact of its launches on local plants and animals. Federal regulators recently fined the company for dumping about 262,000 gallons of wastewater from launches into wetlands in Texas without a permit. SpaceX has denied the allegations.

Rockets Create Holes in Earth’s Ionosphere

A rocket launch has ripped a hole in the Earth’s ionosphere as it accelerated into space. The rocket, belonging to Firefly Aerospace, was carrying the Space Force Victus Nox satellite into orbit as it launched on September 14, 2024 from Vandenberg Space Force Base in California…The ionosphere is a layer of the atmosphere around 50 to 400 miles above, filled with charged atoms (ions). These ions reflect and refract radio signals, making the ionosphere essential to radio communications, which is why radio blackouts occur during solar flares, as the ionosphere is disrupted.

Rockets release exhaust as they ascend, mostly containing water and carbon dioxide, which reacts with the ions in the ionosphere. If the chemistry of the upper atmosphere is disturbed, such as when a rocket flies through it, the carbon dioxide and water molecules from the rocket exhaust change the chemical balance in the atmosphere. This temporarily makes it much easier for the ionization to recombine into neutral atoms, weakening the ionosphere and causing the red glow to be seen…This can lead to a 70 percent drop in ionization in the area that the rocket passes through, particularly in the F-layer at the top of the ionosphere. The red glow in particular comes from oxygen ions, which also glow during the northern and southern lights.

Several recent rocket launches have resulted in a similar phenomenon, including two SpaceX rockets in July and August 2024. The consequences of these holes in the ionosphere are disruptions to radio communication and satellite navigation systems.

The ionosphere absorbs ultraviolet and X-rays from the sun, which is what ionizes the gas atoms in the layer. This prevents these harmful rays from reaching the ground. The holes made by rocket launches do not affect the ionosphere’s ability to filter out this radiation. “While the number of rocket launches is increasing dramatically in recent years, this still constitutes a small amount of gas in comparison with the volume of the upper atmosphere. But if the rate at which rocket exhausts transport water to the upper atmosphere exceeds the rate at which it is removed then the cumulative effect will be a weaker ionosphere.”
