Flying electric taxis

会飞的电动出租车

Long seen as something of a fantasy， flying taxis are getting serious. Several firms around the world will step up test flights with the aim of getting their aircraft certified for commercial use in the following year or two. Joby Aviation， based in California， plans to build more than a dozen of its five-seater vehicles， which have a 150-mile range. Volocopter of Germany aims to provide an air-taxi service at the 2024 Paris Olympics. Other contenders include eHang， Lilium and Vertical Aerospace.

长期以来，会飞的出租车在某种程度上被视为一个幻想，但是这件事正在成真。世界各地的几家公司正在加紧试飞，目标是在接下来的一两年内让他们的飞机获得商业用途认证。总部位于加利福尼亚的Joby Aviation计划制造十多辆五座汽车，这些汽车的航程为150英里（约241千米）。德国 Volocopter 旨在为 2024 年巴黎奥运会提供空中出租车服务。其他竞争者包括 eHang、Lilium和Vertical Aerospace。

Delivery drones

运货无人机

Wing， a sister company of Google， has been doing test deliveries in America， Australia and Finland and will expand its mall-to-home delivery service， launched in late 2021. Dronamics， a Bulgarian startup， will start using winged drones to shuttle cargo between 39 European airports. The question is： will the pace of drone deliveries pick up—or drop off？

谷歌的姐妹公司Wing一直在美国、澳大利亚和芬兰做运货无人机的交付测试，并将扩大其于2021年底推出的商场到家送货服务。保加利亚初创公司Dronamics将開始使用有翼无人机在39个欧洲机场之间运送货物。问题是：无人机交付的速度会加快还是下降？

Personalized nutrition
