Automakers outside China are scrambling to develop electric motor designs that use no permanent magnets, partly because the magnets require rare earths, and mining rare earths causes pollution. It’s also partly because the mining is done in China, a formidable automotive competitor. These alternative motors turn the rotor using electromagnetic force alone; we’ve covered more than one such motor recently. One […]

The Mars Science Laboratory rover Curiosity landed on Mars in August of 2012. After a year of exploring Gale Crater, JPL engineers noticed some wear on Curiosity’s wheels, in the form of dents and small holes in the wheels’ 0.75mm thick aluminum skin. While not unexpected, the wear on the wheels kept increasing at a […]
Image: Turntide Technologies Turntide Technologies, a startup backed by Bill Gates and Amazon, originally pitched its new version of an old electric motor for use in rooftop HVAC systems. Now the company is going after bigger game: electric vehicles. CEO Ryan Morris mentioned the plan in an interview with CNN earlier this month. Now Eric Meyerson, vice president […]
Mars is more crowded than ever. With a successful arrival by the Perseverance rover in February, NASA alone is operating three orbiters, two rovers, and a lander on or around the planet. Other orbiters above the planet are being operated by the European Space Agency, Roscosmos, the Indian Space Research Organization, and others. The China […]
If you haven’t had time to read the AI Index Report for 2021, which clocks in at 222 pages, don’t worry—we’ve got you covered. The massive document, produced by the Stanford Institute for Human-Centered Artificial Intelligence, is packed full of data and graphs, and we’ve plucked out 15 that provide a snapshot of the current […]
When Hawthorne, Calif.-based startup Epirus decided to test a new electronic weapon last winter, it filed an application with the Federal Communications Commission (FCC). It wanted to test its high power microwave device in the California desert east of Palm Springs, about three miles from a small airport and the busy I-10 interstate. The unnamed […]
There’s a reason luggage on an airplane isn’t supposed to contain lithium-ion batteries—they have a tendency to explode into flames. That’s the same reason recreational vehicle manufacturers are embracing lithium iron phosphate, a battery technology with a lower energy density than lithium-ion, but without the fire risk, trading off capacity for safety. Nanom (previously Greenvolt), a startup based […]
