A Houston energy and sustainability expert has been named to a national committee that provides a forum for issues around national efforts to reduce plastic pollution.

Rachel Meidl, a fellow at Rice University’s Baker Institute for Public Policy, was appointed to the Roundtable on Plastics Committee established by the National Academies of Sciences, Engineering and Medicine.

"As a member of the The National Academies of Sciences, Engineering, and Medicine Roundtable on Plastics Committee, our science- and evidence-based work will cover all aspects of the plastics lifecycle and examine interventions in plastic production, waste management, environmental and health impacts, and data collection, management, and modeling," Meidl writes on LinkedIn. "The goal is to pave the way for a sustainable circular economy for plastics. I look forward to working on this important endeavor."

Meidl has more than 27 years of experience in industry, government, policy, finance, international relations, and academia. Her research focuses on sustainability, environmental justice, resiliency, circular economy, safety and environmental regulations of the treatment, storage, disposal and transportation of hazardous materials and wastes.

She also works with understanding environmental, economic and social impacts across energy and material supply chains. Previously, she was appointed deputy associate administrator of the Pipeline and Hazardous Materials Safety Administration in Washington, D.C.. There, she led the agency’s domestic and international strategy, policy and programs.

The roundtable is expected to be a way for federal agencies and experts in academia, industry and nongovernmental organizations to talk about future research initiatives. Activities will include aspects of the plastics lifecycle and potential interventions in plastic production and waste management; material and product design; environmental and health impacts and data collection, management and modeling. The National Academies will address the diversity and complexity of issues in reducing plastic waste by convening various sectors and experts to match each step in the lifecycle of the plastics.

Tesla unveils its robotaxi, plans to bring autonomous driving tech to other models in 2025

hop in

Texas-based Tesla unveiled its long-awaited robotaxi at a Hollywood studio Thursday night, though fans of the electric vehicle maker will have to wait until at least 2026 before they are available.

CEO Elon Musk pulled up to a stage at the Warner Bros. studio lot in one of the company's “Cybercabs," telling the crowd that the sleek, AI-powered vehicles don't have steering wheels or pedals. He also expressed confidence in the progress the company has made on autonomous driving technology that makes it possible for vehicles to drive without human intervention.

Tesla began selling the software, which is called “Full Self-Driving,” nine years ago. But there are doubts about its reliability.

“We’ll move from supervised Full Self-Driving to unsupervised Full Self-Driving. where you can fall asleep and wake up at your destination,” he said. "It’s going to be a glorious future.”

Tesla expects the Cybercabs to cost under $30,000, Musk said. He estimated that the vehicles would become available in 2026, then added “before 2027.”

The company also expects to make the Full Self-Driving technology available on its popular Model 3 and Model Y vehicles in Texas and California next year.

“If they’re going to eventually get to robotaxis, they first need to have success with the unsupervised FSD at the current lineup,” said Seth Goldstein, equity strategist at Morningstar Research. “Tonight’s event showed that they're ready to take that step forward.”

When Tesla will actually take that step, however, has led to more than a little anxiety for investors who see other automakers deploying similar technology right now. Shares of Tesla Inc. tumbled 9% at the opening bell Friday.

Waymo, the autonomous vehicle unit of Alphabet Inc., is carrying passengers in vehicles without human safety drivers in Phoenix and other areas. General Motors’ Cruise self-driving unit had been running robotaxis in San Francisco until a crash last year involving one of its vehicles.

Also, Aurora Innovation said it will start hauling freight in fully autonomous semis on Texas freeways by year’s end. Another autonomous semi company, Gatik, plans to haul freight autonomously by the end of 2025.

“Tesla yet again claimed it is a year or two away from actual automated driving -- just as the company has been claiming for a decade. Indeed, Tesla’s whole event had a 2014 vibe, except that in 2014 there were no automated vehicles actually deployed on public roads,” Bryant Walker Smith, a University of South Carolina law professor who studies automated vehicles, told The Associated Press in an email. “Now there are real AVs carrying real people on real roads, but none of those vehicles are Teslas. Tonight did not change this reality; it only made the irony more glaring.”

Tesla had 20 or so Cybercabs on hand and offered event attendees the opportunity to take rides inside the movie studio lot — not on Los Angeles' roads.

At the presentation, which was dubbed “We, Robot” and was streamed live on Tesla’s website and X, Musk also revealed a sleek minibus-looking vehicle that, like the Cybercab, would be self-driving and can carry up to 20 passengers.

The company also trotted out several of its black and white Optimus humanoid robots, which walked a few feet from the attendees before showing off dance moves in a futuristic-looking gazebo.

Musk estimated that the robots would cost between $28,000-$30,000 and would be able to babysit, mow lawns, fetch groceries, among other tasks.

“Whatever you can think of, it will do,” he said.

The unveiling of the Cybercab comes as Musk tries to persuade investors that his company is more about artificial intelligence and robotics as it labors to sell its core products, an aging lineup of electric vehicles.

Tesla’s model lineup is struggling and isn’t likely to be refreshed until late next year at the earliest, TD Cowen analyst Jeff Osborne wrote in a research note last week.

Osborne also noted that, in TD Cowen’s view, the “politicization of Elon” is tarnishing the Tesla brand among Democrat buyers in the U.S.

Musk has endorsed Republican presidential candidate Donald Trump and has pushed many conservative causes. Last weekend he joined Trump at a Pennsylvania rally.

Musk has been saying for more than five years that a fleet of robotaxis is near, allowing Tesla owners to make money by having their cars carry passengers while they’re not in use by the owners. Musk said that Tesla owners will be able to put their cars into service on a company robotaxi network.

But he has acknowledged that past predictions for the use of autonomous driving proved too optimistic. In 2019, he promised the fleet of autonomous vehicles by the end of 2020.

The announcement comes as U.S. safety regulators are investigating Full Self Driving and Autopilot based on evidence that it has a weak system for making sure human drivers pay attention.

In addition, the U.S. National Highway Traffic Safety Administration forced Tesla to recall Full Self-Driving in February because it allowed speeding and violated other traffic laws, especially near intersections. Tesla was to fix the problems with an online software update.

Last April in Snohomish County, Washington, near Seattle, a Tesla using Full Self-Driving hit and killed a motorcyclist, authorities said. The Tesla driver told authorities that he was using the system while looking at his phone when the car rear-ended the motorcyclist. The motorcyclist was pronounced dead at the scene, authorities said.

NHTSA says it’s evaluating information on the fatal crash from Tesla and law enforcement officials.

The Justice Department also has sought information from Tesla about Full Self-Driving and Autopilot, as well as other items.

Houston geothermal co. expands DOD partnership with South Texas initiative

seeing green

Expanding on its partnership with the United States Department of Defense's Defense Innovation Unit, Sage Geosystems has been selected to conduct geothermal project development initiatives at Naval Air Station in Corpus Christi.

Along with the Environmental Security Technology Certification Program, Sage will provide its proprietary Geopressured Geothermal Systems technology, will be able to evaluate the potential for geothermal baseload power generation to provide clean and consistent energy at the Naval Air Station base.

“We’re pleased to expand our partnership with the DOD at NAS Corpus Christi to demonstrate the advantages of geothermal technology for military energy independence,” Cindy Taff, CEO of Sage Geosystems, says in a news release.

Sage is also conducting initiatives at Fort Bliss and has completed an analysis at the Ellington Field Joint Reserve Base. The analyses could “pave the way for expanding geothermal energy solutions across additional U.S. military installations,” according to Sage.

The company’s proprietary technology works by leveraging hot dry rock, which is a more abundant geothermal resource compared to traditional hydrothermal formations, and it provides energy resilience for infrastructures. In addition, Sage is building a 3 megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, which is expected to be completed by December. Sage also announced a partnership with Meta Platforms. With Meta Platforms, Sage will deliver up to 150 megawatt of geothermal power generation east of the Rocky Mountains.

The Naval Air Station Corpus Christi is considered a critical training and operations hub for the U.S. Navy, and the partnership with Sage shows the Navy's commitment to achieving net-zero carbon emissions by 2045. Sage’s technology will be assessed for its ability to create a microgrid, which can reduce reliance on the utility grid and ensure power supply during outages.

“As we advance our Geopressured Geothermal Systems, we see tremendous potential to not only provide carbon-free power, but also strengthen the operational capabilities of U.S. military installations in an increasingly digital and electric world,” Taff adds.

In September, the Air Force awarded Sage a grant of $1.9 million in a first-of-its kind contract to determine whether a power plant using Geopressured Geothermal Systems is able to generate clean energy needed for a base to achieve energy resilience.
