UltraCell
US startup (Livermore CA): 25-55W reformed methanol fuel cells for military UAVs and soldier power; domain for sale as of 2026, company appears inactive.
UltraCell LLC was a Livermore, California-based startup that developed lightweight reformed methanol fuel cells (RMFC) for military portable power and unmanned systems applications. Founded in the early 2000s, the company focused on the XX-series fuel cell systems: the XX25 (25-watt output) and XX55 (55-watt output) reformer-based methanol fuel cells, designed as compact, silent, and long-endurance power sources for soldier-worn electronics, ground sensors, and small unmanned aerial vehicles (UAVs).
The company's reformed methanol fuel cell technology converts liquid methanol into hydrogen on-board via a catalytic reformer, then generates electricity through a PEM (proton exchange membrane) fuel cell stack. The advantage over batteries is significantly higher energy density per kilogram, which is critical for extended military field operations. UltraCell's systems were evaluated by the US Army and targeted at programs requiring portable power under 100 watts.
As of the research date (July 2026), the domain ultracell-llc.com is listed for sale on GoDaddy at USD 495, indicating the company is no longer actively operating. UltraCell appears to have ceased operations, likely unable to achieve commercial-scale production or sufficient military contract revenue to sustain the business. The company should be considered inactive or dissolved. Its fuel cell technology for UAV and soldier power applications remains relevant to the robotics and defense sectors as a historical reference point for portable hydrogen fuel cell development.

Hyundai's Louisiana Steel Mill to Supply Materials for Robots and SpaceX Rockets
Hyundai Motor Group Executive Chair Chung Euisun announced that steel from the upcoming Hyundai Steel mill in Louisiana could be utilized beyond automotive applications, potentially in Atlas humanoid robots and SpaceX rockets. This vision was shared during the groundbreaking ceremony for the Hyundai-Posco Louisiana Steel plant, which will initially focus on automotive steel production. The $5.8 billion electric arc furnace facility is set to be Hyundai Steel's first production base in the U.S., with an annual capacity of 2.7 million metric tons, including 1.8 million tons dedicated to automotive steel and 900,000 tons for other uses. Chung's comments reflect a long-term strategy to diversify the mill's output, aligning with Hyundai's plans to deploy Atlas robots in U.S. manufacturing operations by 2028. Looking ahead, Hyundai is cautious about deploying Atlas within the steel mill, emphasizing the need for extensive testing. Chung also highlighted the company's efforts to enhance Atlas' development by reorganizing its structure to accelerate technology adoption and improve capabilities in critical components like actuators and grippers.

XDOF Engages in Series B Funding Talks at $1.2 Billion Valuation
XDOF, a startup specializing in real-world teleoperation data for training robots, is in advanced discussions for a Series B funding round, aiming for a valuation of approximately $1.2 billion. The funding is reportedly led by 8VC, following the company's rapid growth and annualized revenue nearing $50 million. The significance of this funding round lies in XDOF's role in addressing a critical bottleneck in robotics: the lack of large-scale real-world datasets. Co-founded by UC Berkeley researchers Philipp Wu and Fred Shentu, XDOF aims to provide outsourced data solutions for the robotics industry, similar to what Scale AI offers for AI applications. Looking ahead, XDOF is set to release what it claims is the largest collection of high-quality robot training data, known as ABC, in collaboration with UC Berkeley's AI Research lab. The startup is also planning to expand its workforce of data collectors globally, which will enhance its capabilities in generating essential training data for robots.

Monumental's CEO Discusses Robotics Potential in Construction Industry
In a recent episode of Lexicon, Salar al Khafaji, founder and CEO of Monumental, highlighted the overlooked potential of robotics in the construction industry. He emphasized the challenges of deploying autonomous robots on unpredictable building sites and the need for specialized machines to address rising construction costs and housing shortages. Al Khafaji pointed out that construction has not received the technological attention it deserves, despite its significant economic and social impact. He believes that the industry is vast and underappreciated by tech founders, which is why he pivoted from data visualization to focus on tangible impacts in construction. Monumental has developed autonomous robots capable of transporting materials and constructing brick walls on commercial sites. However, al Khafaji noted that real-world deployment presents unique challenges, such as varying environmental conditions that affect sensors and computer vision systems.

Pentagon Reports 11 Percent Cost Increase for F-35 Joint Strike Fighter Variants
The Pentagon has announced that the costs for all three variants of the F-35 Joint Strike Fighter are rising by approximately 11 percent. The average flyaway cost for the F-35A has increased to $92 million for production lots 18 and 19, up from $82.5 million, while the F-35B and F-35C have also seen price hikes to $121.4 million and $110.8 million, respectively. This increase in costs is significant as it reflects ongoing challenges faced by the F-35 program, including inflation, rising raw material prices, and supply chain issues. Lockheed Martin, the manufacturer, has indicated that these factors have contributed to the rising costs, which are projected to exceed $50 billion over the program's lifespan due to upgrades and increased spare parts. Looking ahead, the Pentagon plans to acquire 148 aircraft each in lots 18 and 19, totaling 296 aircraft. The F-35 program continues to evolve with modernization efforts, including enhancements to the engine and a new power management system, although some upgrades are behind schedule.

Tesla Reveals New Details About Cybercab, Including Age Restrictions for Passengers
Tesla's recent private event for the Cybercab showcased a stark departure from its typical large-scale launches, with CEO Elon Musk notably absent. The Cybercab promises to be a fully autonomous vehicle utilizing cameras and AI, but details were sparse, primarily shared through PDFs and updates to the 'Robotaxi' app. A significant point of contention is the restriction on minors under 13 from riding in the Cybercab, while those aged 8 to 17 can use the Model Y SUVs, albeit with adult supervision. The implications of these restrictions highlight Tesla's cautious approach to safety amid ongoing investigations by the National Highway Traffic Safety Administration into the Cybercab's rollout. The absence of standard child seat anchors in the Cybercab raises concerns, especially as Tesla aims to ensure the safety of all passengers. The vehicle's safety features, including automatic crash responses, are designed to mitigate risks, but the decision to limit child passengers reflects the company's hesitance to fully embrace its autonomous technology in all scenarios. Looking ahead, Tesla must navigate regulatory scrutiny and public perception as it seeks to validate the safety of the Cybercab. The company's commitment to innovation in autonomous driving will be closely monitored, particularly in light of recent recalls related to electronic door latches. No further timeline was disclosed at the time of publication.
