Underwater mining on land
Waste not, want not
A new robot system will reopen abandoned, flooded mineral workings
陆地水下开采
无遗珠，不匮乏
一个新的机器人系统将会被用来重新开采遭水淹的废弃矿场

THE IDEA of underwater mining is not restricted to the ocean floor (see article). High water tables submerge many terrestrial deposits, too. At minimum, this means doing a lot of pumping to make them workable. Sometimes, it makes those deposits altogether inaccessible. Flooding also adds to the cost of re-opening closed mines. The team behind VAMOS hopes to do something about this.
水下采矿的概念并不局限于海底。高地下水位也淹没了许多陆相沉积物，要开采的话至少也要抽走大量的水。有时候，高水位使得这些沉积物完全无法开采。淹水也增加了重开已关闭旧矿的成本。一个新系统VAMOS的研发团队希望能提供解决方案。

The smaller vehicle is called EVA. It has neutral buoyancy and swims around the mining site. It was designed at the Institute for Systems and Computer Engineering, Technology and Science, in Portugal. EVA first makes, and then continually updates, a 3D map of the area—transmitting this cartography to the main vehicle, to assist navigation.
较小的那台载运器叫EVA。它具有中性浮力，在矿场里四下游动。它是由葡萄牙的计算机与系统工程研究所（Institute for Systems and Computer Engineering, Technology and Science）设计。EVA首先绘制出一幅该地区的3D地图，之后持续更新，并将该地图传送给大载运器以协助导航。
Both vehicles use sonar, cameras and laser rangefinders to work out where they are. They send these data to a pilot in the control centre, who sees them displayed on a multi-screen console of the sort gamers can only fantasise about. A future version may also be able to analyse the ore spectroscopically as it is mined, enabling rich seams to be pursued and poor ones abandoned.
两台载运器都使用声纳、摄像头和激光测距仪来自我定位。它们将相关数据发送给控制中心的引航员。引航员通过一个会让游戏玩家艳羡的多屏幕控制台查看这些数据。未来这套系统或许还能在开采过程中就对矿石做光谱分析，根据分析结果来进一步深挖富矿层而放弃贫矿层。

吧主好，我想问一下，有没有2017年12月9号那一期中，Finance and economics 那一模块的翻译？the world trade orgnization 那一块？官方译文从哪里能找到那？
