An electric cargo ship is delivering coal in China

An all-electric cargo ship is now in use in China and it boasts an impressive 2.4 MWh energy storage capacity, Electrek reports. The ship is over 230 feet long, 45 feet wide and 14 feet deep and can carry a maximum of 2, 000 tons. Supercapacitors and lithium batteries make up the energy storage system and the ship can go about 50 miles on one charge. It will run between two shipyards, each of which has a charging station that can recharge the ship in around two hours. Moving towards electric power will be important for the shipping industry and this vessel is a step in that direction. Its payload however, is, wait for it, coal. And that may seem like an odd pairing but at least the ship isn’t burning fossil fuels while it’s carrying them. Tesla , Daimler , Cummins and Toyota are all working on shipping trucks that use alternative fuels and pushing our cargo ships in that direction will do a lot for the environment. The ship, which took its maiden voyage last month, will transport coal along the Pearl River in China’s Guangdong Province. Via: Electrek

WD’s My Book Duo storage box puts 20TB on your desktop

Western Digital has unveiled the 20TB My Book Duo, its highest-capacity storage system yet, and it’s a good example of the pluses and minuses of spinning hard disks compared to SSDs . The system works at either RAID 0, which offers the maximum speed but no backup protection, RAID 1, for full data protection but lower speeds and JBOD (just a bunch of disks). At RAID 0 levels, it offers decent 360 MB/s speeds, enough to do video editing and other disk-intensive chores. WD says it uses RAID-optimized WD RED drives, which spin at 5, 400 RPM, though it doesn’t specify how many. The box includes a USB 3.1 Type-C interface port and two USB 3.0 Type-A ports that can be used to connect flash drives and other accessories to your PC. They can also charge up your smartphone, letting the drive do double-duty as a USB hub (it comes with a USB-C to USB-C and USB-A cable in the box). The My Book Duo also supports 256-bit AES hardware encryption. The base 4TB model costs $280/£270, while the top end 20TB configuration will set you back $800/£620. As a point of comparison, Samsung just unveiled its portable T5 SSD that costs $800/£760, but you get one-tenth the storage — 2TB. However, you also get a lot more performance, with 540 MB/s from a single drive and the greater reliability of SSDs. In other words, price is the lone advantage left to mechanical disks and the reason why WD is so anxious to keep its relationship with flash storage manufacturer Toshiba.
