BYD launches an electric school bus with two-way charging


As big diesel-burning behemoths that move slowly through areas crowded with small children, school buses are a type of vehicle that is ripe for electrification. Chinese automotive giant BYD is now lending its expertise to the matter with the launch of a battery-electric bus with innovative bi-directional charging tech that could cut into the carbon footprint of the schools that it services.

The new Type-D bus from BYD joins the number of electric school buses we've seen over the last few years, from Daimler and Canada's Lion Bus, among others. Available in lengths of 35, 38 and 40 ft (10, 11.5 and 12 m), the eco-friendly student-mover can seat up to 84 and features dual motors powered by a lithium-iron-phosphate battery that allows for 155 miles (250 km) of travel on each charge.

New tech cheaply produces lithium and H2, while desalinating seawater


But as with other metals like uranium, land-based lithium reserves pale in comparison to what's out there in the sea. According to researchers at Saudi Arabia's King Abdullah University of Science and Technology (KAUST), there's about 5,000 times as much lithium in the oceans as there is in land deposits, and a newly developed technology could start extracting it cheaply enough to make the big time – while producing hydrogen gas, chorine gas and desalinated water as a bonus.

How your phone’s low power mode actually works


Smartphone battery life is a precious resource: If you don’t manage it carefully, you might find yourself unable to make calls, take photos, or check social media by the end of the night. A dead phone is pretty much useless until you can find a charging point.

To extend your phone’s battery capacity, Android and iOS both have a special battery-saving mode that helps your handset hang on just a little longer.

1,000-foot multi-rotor floating Windcatchers to power 80,000 homes each


Norway's Wind Catching Systems (WCS) has made a spectacular debut with a colossal floating wind turbine array it says can generate five times the annual energy of the world's biggest single turbines – while reducing costs enough to be immediately competitive with grid prices.

Standing more than 1,000 ft (324 m) high, these mammoth Windcatcher grids would deploy multiple smaller turbines (no less than 117 in the render images) in a staggered formation atop a floating platform moored to the ocean floor using established practices from the oil and gas industry.

Ships releasing alkalinizing agents could buy time for Great Barrier Reef


The increasing buildup of carbon dioxide in the atmosphere is reshaping the environment in many ways beyond the ongoing rise of global temperatures. Some major ones relate to the ocean, which is becoming not just warmer but also more acidic, threatening to degrade the world's coral reefs. Researchers have put forward an interesting way of preventing some of this damage, through a study demonstrating how releasing an alkalinizing agent from shipping lanes could protect much of Australia's Great Barrier Reef.

Victory! New York Senate Passes Landmark Right to Repair Bill


“In passing this bill, the New York Senate proved they’re not afraid to stand up to powerful interests by fighting for the rights of all New Yorkers to fix, and truly own, their devices,” said Kerry Maeve Sheehan, U.S. policy lead for iFixit. “This is a major win for small repair businesses throughout the state, for the environment, for low income communities, and for everyone who just wants to be able to fix their stuff.”

Extraordinary new material shows zero heat expansion from 4 to 1,400 K


Australian researchers have created what may be one of the most thermally stable materials ever discovered. This new zero thermal expansion (ZTE) material made of scandium, aluminum, tungsten and oxygen did not change in volume at temperatures ranging from 4 to 1400 Kelvin (-269 to 1126 °C, -452 to 2059 °F).

That's a wider range of temperatures, say scientists from the University of New South Wales (UNSW), than any other material demonstrated to date, and it could make orthorhombic Sc1.5Al0.5W3O12 (catchy name, eh?) a very handy tool for anyone engineering something that needs to work in extremely varied thermal environments.

How the Mormon church unlocked medical pot for deep red states


Despite the national popularity of legalizing marijuana, 14 states — mostly in the Deep South and the Great Plains — have not embraced it for medical use. Triangulating around growing support and nudged along by the personal touch of its members, the Mormon church helped greenlight a medical marijuana program industry advocates may use to succeed in deeply conservatives places like Idaho or Kansas.
