Elon Musk's $1B Tesla stock purchase, made via his personal trust, sparked a surge in share price and raised questions about how the buy was funded. Likely financed through margin loans, derivatives, or asset reallocation, the move increased Musk's net worth by up to $8.6B. The timing aligns with Tesla's proposed $1T compensation plan, suggesting a strategic gesture to boost investor confidence and governance optics.
Extreme H is the world's first hydrogen-powered off-road racing series, debuting in Qiddiya City, Saudi Arabia. Evolving from Extreme E, it features gender-equal teams, zero-emission Pioneer 25 SUVs, and green hydrogen supplied via electrolysis. The rugged desert course tests fuel cell performance on gradients up to 130%. Backed by Saudi Vision 2030, the series aims to prove hydrogen's viability and promote sustainable motorsport innovation.
Seattle's Sound Transit has expanded its Link light rail system to 45 miles, offering fast, affordable, and eco-friendly travel powered by hydro and wind energy. Ridership hit 3.08 million in October 2024, with fares as low as $1 for seniors and free for youth. A Lynnwood–SEA Airport trip takes 80–85 minutes by rail, beating car travel in cost and emissions. Despite success, Sound Transit faces need for a substantial financial overhaul.
The FAA launched the eVTOL Integration Pilot Program (eIPP), a 3-year initiative inviting governments and private partners to test electric air taxis and other advanced air mobility (AAM) aircraft. The goal is to gather data to shape future regulations and demonstrate real-world use cases like cargo and medical transport. Companies like Joby, Archer, Beta, and Wisk plan to participate, aiming to revolutionize U.S. air travel.
Arc signed a $160M deal with Curtin Maritime to deliver eight hybrid-electric tugboats, marking the largest commercial deployment of electric workboats. Built with Snow & Co, the tugs feature Arc's 4,000+ HP electric powertrains and 6 MWh battery buffers. The first four are due by 2027. The project aims to modernize U.S. ports with efficient, low-maintenance, cost-effective vessels, challenging diesel norms and advancing marine electrification.
Hydrogen's Flight Path: Fuel Cells, Turbines, and the Economics of Clean Aviation
10 Oct 2025 | Aviation is shifting from Jet A to four fuel systems: electricity, hydrogen (fuel cell and combustion), SAF, and petroleum. Fuel cells suit short-haul aircraft; hydrogen combustion may power long-range jets. SAF bridges legacy fleets. Hydrogen costs - $5-$7/kg today, possibly $2/kg by 2040 - impact ticket prices and infrastructure decisions. Airport authorities, airlines, and governments will share deployment costs. Each fuel has distinct environmental pros and cons shaping aviation's net-zero future.
