After two reports emerged of Boosted Boards spewing dense smoke from their batteries, the company issued a statement urging all riders to stop using the newer second-generation boards. Now, the electric skateboard maker is taking more drastic measures, working with consumer protection agencies in the US and Canada to issue a recall.
On Wednesday, web developer Rick Bross was faced an unusual problem. His electric skateboard's battery malfunctioned, filling his entire apartment with smoke and scaring the hell out of his roommate. The incident was just one of two recent cases involving Boosted Boards, a brand of electric skateboards, where the batteries spontaneously "vented", a non-technical term used by the company to describe an electrical engineering problem also known as thermal runaway that causes batteries to overheat and potentially explode.
Tesla has just created the fastest car you can buy — and it's all thanks to the company's new 100 kilowatt-hour (kWh) battery. The Model S P100D with Ludicrous Mode is a slightly upgraded version of the Model S P90D (with a 90 kWh battery) that was released in March. But this new version can go 0-to-97km/h in just 2.5 seconds.
The MOS Go is a USB powerbank with a sizeable 12000mAh capacity, but it also has an extra handy hook for anyone with a new USB Type C-capable laptop like the 12-inch Apple MacBook or the HP Spectre — it can charge these significantly larger, more power-hungry notebooks through its high-power reversible output. After a long wait, it's now on sale.
The next generation of rechargeable lithium batteries set to change the electric vehicle industry may soon be here, thanks to the humble salt bath.
CSIRO scientists, in collaboration with RMIT University and QUT, have found that pre-treating a battery's lithium metal electrodes with an electrolyte salt solution extends the battery life and increases performance and safety, to a point where electric vehicles will soon be competitive with traditional petrol vehicles.
Windows 10 (like its predecessor, Windows 8.1) comes with a hidden battery report feature that you can only access from the command line. The report provides detailed readouts on the usage, status, and health of your laptop's battery. It can be an invaluable tool in making sure your system's running smoothly and spotting power problems before they get serious.
