  • Some good stats in the article:

    … bicycles already surpass cars as a means of transportation in the interior of Paris, accounting for 11.2% of trips compared to 4.3%. A similar trend is seen in trips between the suburbs and the city center: 14% are made by bicycle and 11.8% by car.

    Rue de Rivoli, with its two-way cycle lanes and its dedicated lane for buses and taxis …

    … Paris has more than 1,000 kilometers (621 miles) of facilities adapted for cyclists, including more than 300 km (186 m) of bike lanes and 52 km (32 m) of provisional lanes, according to the latest available municipal data, from 2021. The rest are lanes shared with cars or lanes only marked with paint on the ground.

    By 2026, local officials want the entire city to be suitable for two-wheel transportation. To this end, it has set aside $250 million, $100 million more than in Hidalgo’s first term.

    … only 27% of the “bike plan” has been carried out despite the fact that 62% of Hidalgo’s second term in office has already elapsed.

    … indicated that 11.2% of trips in Paris were made by bike between 2022 and 2023, compared to 4.3% by car. The change in trend is clear. In 2021, two wheels still represented 5.6% of trips, while cars were 9%, according to Belliard.

    … the research indicates that residents of the nearest suburbs also prefer to use the bike, with 14% of trips compared to 11.8% for cars. The figures are even better during rush hour, when 18.9% of trips are made by bike and only 6.6% by car. Travel on foot, however, continues to lead mobility within the municipality with 53%, followed by those made on public transit, with 30%. The study was carried out with 3,337 residents of the capital region who agreed to be fitted with a GPS tracker.




  • Besides the additional Norway airplanes, this was new information to me:

    The primary bottleneck to the Ukrainian Air Force’s fielding F-16s in quantity is not limited numbers of airframes but how many combat pilots and ground crew Kyiv can spare from the actual war, to train on transition to the F-16, Cavoli said.

    According to Ukrainian mil-bloggers, the first six F-16s with pilots and ground crew will reach Ukraine in June or July. Earlier deadlines had predicted the arrival in April or May.

    What alternatives to plastic are coming?

    Here are a few new ideas headed to the produce aisle:

    Bags from trees. An Austrian company is using beechwood trees to make biodegradable cellulose net bags to hold produce. Other companies offer similar netting that decomposes within a few weeks.

    Film from peels. Orange peels, shrimp shells and other natural waste is being turned into film that can be used like cellophane, or made into bags. An edible coating made from plant-based fatty acids is sprayed on cucumbers, avocados and other produce sold at many major grocery stores. They work in a way similar to the wax coating commonly used on citrus and apples.

    Clamshells from cardboard. Plastic clamshells are a $9.1 billion business in the United States, and the number of growers who use them is vast. Replacing them will be an enormous challenge, particularly for more fragile fruits and vegetables. Plenty of designers are trying. Driscoll’s has been working to develop paper containers for use in the United States and Canada. In the meantime, the company is using more recycled plastic in its clamshells in the United States.

    Ice that feels like gelatin. Luxin Wang and other scientists at the University of California, Davis, have invented reusable jelly ice. It is lighter than ice and doesn’t melt. It could eliminate the need for plastic ice packs, which can’t be recycled. After about a dozen uses, the jelly ice can be tossed into a garden or the garbage, where it dissolves.

    Boxes with atmosphere. Broccoli is usually shipped in wax-coated boxes packed with ice. The soggy cartons can’t be recycled. Iceless broccoli shipping containers use a mix of gases that help preserve the vegetable instead of chilling it with ice, which is heavy to ship and can transmit pathogens when it melts. Other sustainable, lighter shipping cartons are being designed to remove ethylene, a plant hormone that encourages ripening.

    Containers from plants. Rice-paddy straw left over after harvests, grasses, sugar cane stalks and even food waste are all being turned into trays and boxes that are either biodegradable or can be composted.


  • From the article:

    The last coal producers in New England will shutter their doors permanently under an agreement reached with environmental groups and the Environmental Protection Agency (EPA) on Wednesday.

    Two plants in New Hampshire, Schiller and Merrimack, will voluntarily cease operations in 2025 and 2028, respectively, said Jim Andrews, president and CEO of Granite Shore Power.

    By closing the plants, Granite Shore Power — the company that operates them — resolved litigation brought by the Conservation Law Foundation and the Sierra Club, which alleged they violated the Clean Water Act.

    The region’s coal-free status comes as part of a larger pledge by the U.S. to phase out coal power plants through the Powering Past Coal Alliance. The U.S. joins 56 other nations in committing to no new coal plants and the closing of existing operations.

    The U.S. has not named a target date for completing the transition, but the Biden administration, through other works, has indicated a plan aimed at no coal by 2035.

    New Hampshire will become the 16th coal-free state in the nation, according to a statement by the Sierra Club.

    Facilities like Merrimack have fallen short of emissions requirements in the past, exceeding one emissions limit by 70 percent in 2023, according to reporting from New Hampshire Public Radio. Previous failures to meet requirements did not inform the company’s decision, Andrews said.

    He has said that new “renewable energy parks” of solar arrays and storage facilities will be developed.


  • Thought this was a cool part of the article:

    The acoustic sensors gather uncharacteristic sounds from the environment before artificial intelligence is used to establish whether anomalies are incoming kamikaze drones or missiles.

    Dr Thomas Withington, an expert in air defence at the Royal United Services Institute said: “It’s interesting that this technology is making a comeback because it was all the rage before the invention of the radar in the 1920s and 1930s

    “History, in a sense, comes full circle, but with the adaptation of the technological age that we have today.”
