Tesla’s investor day on 1 March began with a rambling, detailed discourse on energy and the environment before transitioning into a series of mostly predictable announcements and boasts. And then, out of nowhere, came an absolute bombshell: “We have designed our next drive unit, which uses a permanent-magnet motor, to not use any rare-earth elements […]
Cars aren’t the only conveyances being transformed by electricity. Along with electric motorcycles and snowmobiles, personal watercraft are floating better ways to coexist with nature and neighbors. This new breed of machines brings requisite thrills to the Great Outdoors, but without fouling the atmosphere or disturbing the peace with an internal-combustion racket. The latest comes […]

An increasingly-seen sight in Berlin and other German cities is the oversized electric cargo delivery bike, hissing along (and sometimes in bike lanes) like parcel-laden sailboats on appointed Amazon rounds. German manufacturer Schaeffler sees an opportunity: it is introducing a new generator at the heart of a smart drivetrain concept that some observers are calling […]
In 1820, the Danish physicist Hans Christian Ørsted threw electromagnetic theory into a state of confusion. Natural philosophers of the day believed that electricity and magnetism were two distinct phenomena, but Ørsted suggested that the flow of electricity through a wire created a magnetic field around it. The French physicist André-Marie Ampère saw a demonstration […]
