  波尔图桑塔政府想要的是清洁的、可再生能源。他们选择的解决方案是——电动汽车,但不是我们所知道的那种电动汽车。 [ti:] [ar:] [al:] [by:小e英语] [00:00.00]The savage beauty of Porto Santo attracts tourists who love nature. 电动汽车岛波尔图桑塔的原始美景吸引着热爱大自然的游客。 [00:05.49]But people need energy and the way its generated here is damaging nature. 但是人们的生活需要能源,而这里制造能源的方式正在破坏自然环境。 [00:10.83]This pollutions coming from the diesel generator which powers the islands homes. (画面中的)这种污染来自岛上居民使用的柴油发电机。 [00:16.57]Transporting the diesel is expensive and its fuelling climate change. 运输柴油非常昂贵,运输过程也加剧了气候变化。 [00:21.61]The local government want clean, renewable energy instead.当地政府想要的是清洁的、可再生能源。 [00:25.96]But wind power and solar power ebb and flow, so they need a way of storing energy for use at nighttime. 但是风能和太阳能不够稳定,所以它们需要一种储存能量的方法,以供夜间使用。 [00:33.65]Heres the chosen solution - the electric car, but not as we know it. 这就是他们选择的解决方案――电动汽车,但不是我们所知道的那种电动汽车。 [00:40.10]In future, electric vehicles here will be fitted with a reversible battery that stores energy for the electricity grid. 未来,这里的电动汽车将配备一种可逆电池,为电网储存能量。 [00:47.67]So how does a reversible battery work? 那么可逆电池是如何工作的呢? [00:50.56]When the Sun is shining, the electricity flows out of the grid, down the cable and into the car. 当阳光充足时,电力从电网中流出,顺着电缆流入汽车。 [00:56.26]Then its stored in the battery until nighttime, when it flows back out of the car, up the cable and into the grid to power peoples homes. 然后它被储存在可逆电池里,直到夜晚,它再流出汽车,通过电缆进入电网,为用户家庭供电。 [01:05.24]The car is smart, so it keeps enough power for itself to be driven. 这辆汽车很智能,所以它还能保持足够的动力供驾驶使用。 [01:14.93]On Porto Santo, some police [cars] are already powered by electricity. 在波尔图桑塔,一些警车已经靠电力驱动。BBC: 电动汽车岛 电力革命将带来更多惊喜 [01:17.69]To run an effective backup for the local grid, half the cars on the island, like this electric taxi, will need to store power as well as using it. 为了给当地电网提供有效的电力备份,岛上一半的汽车,比如这款电动出租车,需要储存和使用电力。 [01:25.32]So is this the road to the future? 这是通往未来的道路吗? [01:27.41]Well, a couple of years ago, if youd suggested that car batteries could play a major part in supporting an electricity grid, a lot of people would have laughed. 几年前,如果你说汽车电池可以在支持电网方面发挥重要作用,很多人都会觉得这是个笑话。 [01:37.53]But that is exactly whats happened. 但事实正是这样。 [01:40.58]The electricity revolution is going to create a lot more surprises. 电力革命将带来更多的惊喜。
