Modern trolleybuses using in-motion charging (IMC) are making a comeback as cost-effective, grid-friendly alternatives to battery-electric buses. They charge via overhead wires and run off-wire using small batteries, reducing infrastructure and maintenance costs. Ideal for dense, hilly cities or those with legacy systems, they face funding and public perception challenges but offer strategic advantages in urban transit electrification.
A new study from Chalmers University, featured in Air Quality News, finds that e-bikes pose a significantly higher crash risk than e-scooters—over eight times greater when accounting for exposure factors like trip distance and duration. The research analyzed GPS data from shared micromobility services across seven European cities, offering a more accurate comparison than previous studies. The authors call for better data-driven safety policies.
Electric fishing boat Heron launched in rural Maine, powered by twin electric outboards and backed by $1M in grants. Operated by Maine Ocean Farms, it cuts emissions, noise, and fuel costs. The shift supports climate goals amid warming Gulf waters. Challenges include battery weight and limited charging, but local groups are expanding infrastructure. Heron signals a sustainable future for aquaculture and rural marine industries.
The Bristell B23 Energic, an all-electric trainer aircraft from BRM Aero and H55, offers smooth handling, low operating costs ($8–$9/hr), and a 60-minute flight time under EASA rules. FAA limits U.S. flights to 40 minutes due to stricter reserves, but upgrades are planned. Despite reduced payload from battery weight, performance rivals piston aircraft. Its success signals growing momentum in electric aviation.
Leaked images reveal Rivian's upcoming e-bike, developed by its spinoff ALSO Inc. The sleek, silver prototype features full suspension, cargo rack, and inverted fork - blending utility with Rivian's signature design. Backed by a $1B valuation, ALSO aims to disrupt micromobility with a bold October launch. The bike signals Rivian's move beyond trucks, building a broader electric mobility ecosystem for urban riders and lifestyle commuters.
13 Oct 2025 | California broke its ZEV sales record in Q3 2025, hitting 124,755 units and 29.1% market share. The surge was fueled by expiring federal incentives, but sustained by state infrastructure, rebates, and growing model diversity. Tesla's dominance is waning as non-Tesla brands gain ground. With 200,000+ public chargers and a 35% ZEV target by 2026, California's EV market shows lasting momentum and offers a blueprint for national adoption.
13 Oct 2025 | The Las Vegas Review-Journal editorial warns of rising costs from clean energy, but critics argue renewables are now cheaper than fossil fuels. Infrastructure upgrades and legacy fuel contracts - not solar or wind - drive higher bills. Fossil fuels carry hidden costs like pollution and health impacts. Clean energy investments are transitional and necessary. The real challenge is managing the shift, not avoiding it. Clinging to fossil fuels is costlier long-term.
Harnessing the Wind: Rotor Sails on Scandinavian Ferries
13 Oct 2025 | Scandlines ferries use rotor sails - spinning cylinders that harness the Magnus effect to generate lift and reduce fuel use. Most effective in crosswinds, the rotors spin to face the wind and produce forward thrust. Modern versions use lightweight composites and electric motors powered by hybrid systems. Though ineffective in headwinds, they switch to engine power, avoiding stall. Fuel savings reach up to 20%, aiding Scandlines' goal of emission-free operations by 2040.
Singapore Awards Groundbreaking Contract for Level 4 Autonomous Bus Trial
12 Oct 2025 | Singapore's LTA has awarded a contract to MKX Technologies, MOGOX, and BYD to launch Level 4 autonomous electric buses by 2026. Six 16-seater buses will operate on Services 191 and 400, with MOGOX providing self-driving tech, BYD supplying the buses, and MKX managing the project. Safety operators will be onboard initially. The trial supports Singapore’s smart mobility goals and could expand to 100–150 buses if successful.
