Airlines aren’t the worst polluters in the world, but planes do account for an incredible 2.5% of the world’s carbon emissions. So by any measure, flying is a privilege—the exact sort of 21st-century excess that we need to reassess. 航空公司并不是世界上最严重的污染源，但飞机排放的二氧化碳却达全球碳排放总量的2.5%。因此，无论以何种标准衡量，飞行都是一项特权，确切的说，是我们需要重新考虑的21世纪的过度消费品。 Which is why the strategic design consultancy Manyone is thinking about radical alternatives to flight. The studio’s solution? A giant train that loops around half the world like a mega subway system. 这就是战略设计咨询公司Manyone正在考虑全新的飞行替代方案的原因。该工作室有什么解决方案吗？那就是设计一列长达地球半圈距离的巨型火车，就像巨大的地铁系统一样。 Dubbed the AeroSlider, it’s an elevated train line that passes through a series of unobtrusive magnetic loops instead of running on a track. Much like the principles behind a rail gun, the loops speed up the train sequentially, propelling it up to speeds of 500 mph—or the average speed of a plane. It was conceived by creative director Jens Martin. 这条高架铁路线被称为AeroSlider，它是经由一系列不显眼的磁环运行，而不是在轨道上运行。就像电磁轨道炮的原理一样，这些磁环相继加速列车，将其速度提升至500英里每小时，或飞机的平均速度。它是由创意总监延斯·马丁提出的。 |
