Indigenous Peoples’ Day was first officially proclaimed by US President Joe Biden in 2021. Acknowledging that it is imperative to uphold the rights and dignity of the indigenous people who were here long before colonization of the Americas began, Biden also admitted that US federal policies systematically sought to assimilate … [continued]
Glasgow and London both use private bus operators; the important difference is who designs the passenger network they collectively deliver.
Walk around Glasgow as I did this summer and the bus companies are hard to miss. First Glasgow, McGill’s, Stagecoach and other operators have their own brands and vehicles, which can make the city look as though its public transport system has been divided among private companies. Being a bit … [continued]
Across hundreds of procurement records and very different transit markets, battery-electric has become the reference technology for zero-emission bus fleets.
Zero-emission bus procurement has moved beyond the stage where battery-electric and hydrogen fuel-cell buses should be treated as two parallel technologies waiting for the market to decide between them. Transit agencies have now spent years operating both, rebuilding depots, installing charging and refuelling infrastructure, training technicians and discovering which assumptions … [continued]
Healthy social housing has to provide winter warmth, summer safety and clean indoor air, while retrofit sequencing determines how quickly residents receive those benefits.
“Fabric first” starts from a sensible building-efficiency idea. Improve insulation, stop unnecessary draughts, fix ventilation and reduce heat demand before replacing a gas or oil boiler with a heat pump. Some homes plainly need that work, and cheap measures such as loft insulation, draught repair and basic remediation can be … [continued]
Graphyte can deliver durable carbon removal, but burial should compete with the other useful services the same biomass could provide first.
Graphyte’s Carbon Casting process is unusually tangible for engineered carbon removal. Residual biomass is dried, compressed into dense blocks, protected from water and microbes, and stored underground so its carbon stays out of the atmosphere for a very long time. Compared with direct air capture and some other carbon-removal proposals, … [continued]
Hawaiʻi’s proposed LNG bridge has a costly possible exit in imported green ammonia, while local solar and storage offer another path.
The argument for bringing liquefied natural gas to Oʻahu is straightforward enough. LNG could replace oil for a period, potentially lower generation costs and give Hawaiʻi more time to build out renewable electricity. The difficulty is that Hawaiʻi law requires electric utilities to reach 100% renewable electricity generation by 2045, … [continued]
An October 5, 2026 letter to the editors of the Boston Globe reads as follows: “So we are preparing to spend billions of dollars adapting to the effects of climate change. Sea walls, levees, and other forms of flood prevention are definitely needed, and there’s no time to waste. But … [continued]
Most NYC e-bike and pedestrian deaths occur in crashes involving motor vehicles. That does not establish fault, but it changes the framing.
A recent New York Times newsletter described fatal e-bike and electric-scooter crashes in New York City as reaching a record high. “Record” is a powerful word, especially when the vehicles involved are relatively new, but it can also direct attention toward what the victim was riding and away from what … [continued]
Heart’s ES-36 keeps electric motors at the propellers while turbogenerators extend missions beyond practical battery range.
On August 12, Heart Aerospace flew its X1 demonstrator for 27 minutes from Plattsburgh International Airport in New York. The aircraft weighed more than 25,000 pounds, had a 106-foot wingspan and put more than a megawatt through its electric propulsion system while taxiing, taking off, climbing, maneuvering and landing. There … [continued]
Kraaken combines ocean thermal generation, AI computing, freshwater production and storm mobility in one offshore platform. The engineering question is whether all of those physical flows and interfaces can reconcile in the same 100 MW system.
A floating data centre that generates its own electricity from the ocean, cools itself with seawater, produces drinking water for a coastal community and can sail away when a hurricane approaches is almost tailor-made for the current AI data center hype bubble. Optimal Transit’s Kraaken concept is ambitious even by … [continued]
