為更有效地降低車輛碳排放，荷蘭埃因霍溫科技大學的一個學生團隊打造了一款非常特別的電動原型車。這臺被命名為ZEM的電動車在行駛過程中不僅不會產生碳排放，還會吸收和儲存其周邊空氣中的二氧化碳。

The sporty all-electric car from the Netherlands resembles a BMW coupe, but is unique: It captures more carbon than it emits.
這輛來自荷蘭的運動型電動汽車外觀酷似寶馬跑車，但卻有其獨特之處：它吸收的碳比排放的碳要多。

"Our end goal is to create a more sustainable future," said Jens Lahaije, finance manager for TU/ecomotive, the Eindhoven University of Technology student team that created the car.
荷蘭埃因霍溫理工大學的學生團隊TU/ecomotive是這款汽車的研發(fā)者，團隊財務經理延斯·拉海耶稱：“我們的最終目標是創(chuàng)造一個更可持續(xù)的未來?！?/p>

Called ZEM, for zero emission mobility, the two-seater houses a Cleantron lithium-ion battery pack, and most of its parts are 3D-printed from recycled plastics, Lahaije said.
拉海耶稱，他們將這輛雙座車命名為ZEM，也就是zero emission mobility（零排放出行）的縮寫。車上裝有Cleantron公司的鋰電池組，車體大部分部件由回收塑料3D打印而成。

The target is to minimize carbon dioxide emitted during the car's full lifespan, from manufacturing to recycling, he added.
拉海耶還表示，他們的目標是從汽車制造到報廢回收的整個周期內，最大限度地減少二氧化碳排放。

Battery electric vehicles emit virtually no CO2 during operation compared with combustion-engine vehicles, but battery cell production can create so much pollution that it can take EVs tens of thousands of miles to achieve "carbon parity" with comparable fossil-fueled models.
與燃油車相比，電動車在運行過程中幾乎不排放二氧化碳，但生產電池會產生大量污染，因此當車輛行駛里程達到數(shù)萬英里時，電動車的全周期碳排放與燃油車相當。

據TU/ecomotive團隊官網介紹，ZEM可以通過直接空氣捕捉技術，在車輛行駛時捕獲空氣內的二氧化碳，并將其收集到過濾器中。

“Direct air capture is a fairly new method of cleaning the air by capturing CO2 into a filter. We have made use of this innovative technology and implemented this in our car. The idea is very simple: while driving, air will move through our self-designed filters and the CO2 will be captured and stored.”
“直接空氣捕捉技術是一種通過將二氧化碳捕獲到過濾器中來凈化空氣的全新方法。我們將這項創(chuàng)新技術應用到ZEM汽車上。這個想法很簡單：在車輛行駛時，空氣將通過我們自行設計的過濾器，其中的二氧化碳將被過濾器捕獲和儲存?！?/p>

ZEM uses two filters that can capture up to 2 kilograms (4.41 lb) of CO2 over 20,000 miles of driving, the Eindhoven team estimated. They imagine a future when filters can be emptied at charging stations.
埃因霍溫團隊估測，ZEM的兩個過濾器可以在20000英里的行駛里程中捕獲高達2千克的二氧化碳。他們設想未來可以在充電站將過濾器中的二氧化碳清空。

The students are showing their vehicle on a US promotional tour to universities and companies from the East Coast to Silicon Valley.
從東海岸到硅谷，學生們正在美國的大學和公司巡回展示他們的汽車。
