"The amount of heat accumulating near the surface of the planet is currently more than twice as high as even the best climate change models could have predicted..."During the first decade of this century, for instance, the imbalance was around 0.6 watts per square meter, yet by 2023 this had shot up to 1.8 watts per square meter...The root cause of the discrepancy between models and observations is currently not well known."

"The boats are catamaran-type vessels, as their design makes them suitable for shallow waters...Each boat will carry up to 32 passengers at a time and will be accessible for people with disabilities and cyclists."The first route will link Zirmunai and Zveryna...The trip is expected to take between 45 and 55 minutes.
"The total value for purchasing and servicing four electric boats is 1.85 million euros."

"...few potential reasons for this, some of which are related to the way the driver interacts with the EVs controls, and others due to how our brains process the signals we're receiving while being transported."Greater sickness in EVs can be attributed to a lack of previous experience, as both a driver and as a passenger, where the brain lacks accuracy in estimating the motion forces because it relies on previous experience in other types of cars."

"Founded in 2019, Ryde's CEO Tobias Balchen notes "In several cities, it can't meet rider demand due to strict fleet caps – "we'd see significantly higher ridership if the regulations allowed more flexibility"Ryde rolled out 30,000 new e-scooters across its Nordic markets this spring. With this expansion, the operator is targeting 50 million trips in 2025 alone...started planning its entrance into new markets beyond the Nordics in 2026."

"...most of the half million school buses on the road are diesel-powered...The toxic exhaust from diesel-burning buses is unsafe for students, drivers, and residents of the communities they drive through and park in."...electric school buses [are] the only type of school bus with no tailpipe emissions. Over a quarter of a million students already ride these clean buses to school each day.
"46 percent of Americans - 156.1 million people - are living in places that get failing grades for unhealthy levels of ozone or particle pollution. "

We "say food is fuel, which turns out to be a perfect metaphor for understanding how electric vehicle batteries work - they're built like lasagna."In our current battery design, each module holds 24 battery cells, technically called pouch form factor cells - our 24 servings of lasagna...The key to good lasagna is keeping the ricotta and sauce from mixing into a gooey mess...while in a battery cell, a thin polymer separator keeps the cathode and anode materials apart."

"SiriNor's engine represents a breakthrough in non-combustion jet propulsion. Unlike traditional turbines that rely on burning jet fuel, this system uses electricity to power tip-mounted motors around a central fan, effectively driving airflow through the engine."The aircraft likely to adopt these engines first will be in the 9- to 30-seat range - suitable for regional hops of 500 to 900 kilometers."

"Buses - including city, coach and school buses - make up approximately 5% of global transport carbon dioxide emissions. Electrifying the bus fleet could also provide a model for electrifying trucks, which make up about a quarter of transport emissions."Five countries - China, the Netherlands, Finland, Switzerland and Denmark - are already setting an example by growing their electric bus sales from less than 6% to more than 60%..."

"A US District Court judge in Washington State has ruled that the feds must un-freeze roughly $1 billion in funding...while funds were available for all states, only 16 filed suit...alleged that the funding freeze was illegal... California Attorney General Rob Bonta called [the Administration's] move "unconstitutional"...California looks forward to continuing to vigorously defend itself from this executive branch overreach..."27 Jun 2025 | Synopsis
"A wide grille-style bow and fuselage cockpit are the key F1-styling features and once it is foiling it looks for all the world like F1 throwback on stilts."The advantage of hydrofoils is that they offer much less water resistance, once a craft is going fast enough to create the required lift from the wings under water...
"FoilOne are not alone in heading down the hydrofoil route and the market for eclectic, foiling motor boats is in the on-the-water cost will likely be closer to €120,000"

"According to BikeExchange data from 2024, used e-bikes typically retain 40–70% of their original price, depending on condition, battery life, and brand reputation. My Trek e-bike, which I bought for $2,800, ended up selling for $1,950 after some negotiation.
"That's about 70% of the original price...key factor wasn't just the bike's condition - it was the brand recognition and the fact that the battery still held a strong charge after two years of regular use."

Candela CEO and founder Gustav Hasselskog claims that aside from the environmental advantages, the P-12 costs up to 90 per cent less to run, per seat, than a diesel equivalent."The P-12 has a range of 40 nautical miles...and can cruise at 25 knots, or 46 km/h....Sydney Harbour ferries typically have a maximum speed of 15 knots.
"Olympic gold medal-winning British sailor Iain Percy founded a company called Artemis that is also building foiling electric ferries."
