| 中文简介: |  汽车行业：未来的挑战和机遇我们为汽车成瘾付出了沉重的代价。丹尼尔·鲁斯（Daniel Roos）首先介绍了美国汽车制造商的困境，美国汽车制造商的市场份额正在下降，而且随着外国制造商迁往美国，它们的工厂也关闭了。 Roos建议按订单生产系统，以降低效率。当太多的人开车太多时会发生什么？中国人最近转换为燃烧汽车，拥有2400万辆汽车，并提供了悲惨的新统计数据：107,000人的汽车死亡人数，是美国的两倍多，在这里，单车司机为人流量少的道路支付更高的费用；进入人口稠密的市区的费用；和计算机运行的智能交通系统。未来的汽车技术和燃料：选择及其影响尽管约翰·海伍德（John Heywood）说：“我们太多人经常使用太多东西，但汽车可能被证明是最糟糕的商品。它们负责生态系统的稳定退化，从温室气体排放到生物多样性丧失。更糟糕的是，即使我们提高了车辆效率，转向了普锐斯（Prius）等混合动力汽车，或者在氢燃料技术上取得了飞速发展，减缓降解的规模也可能持续数十年。目前，我们在美国的道路上有1.3亿辆汽车，而且每年还会增加1500万辆。海伍德说：“改变曲线并不容易。” “人类根本不会尽力而为。”建议：采用综合政策方法，包括更好的里程标准和严格的汽油税。 |
| 课程简介: | The Automotive Sector: Future Challenges and Opportunities We pay a stiff price for our car addiction. Daniel Roos starts with the plight of American auto manufacturers, whose market share is dropping and whose plants close as foreign makers move to the U.S. They are victims of their own overproduction. Roos recommends a build-to-order system to reduce inefficiencies. What happens when too many people drive too many cars? The Chinese, recent converts to combustion, boast 24 million vehicles and a tragic, new statistic: 107 thousand auto fatalities, more than twice as many as in the U.S. Some measures for car-clotted areas may be high occupancy toll lanes (aka Lexus Lanes), where solo drivers pay more for less trafficked roads; fees for entering densely traveled urban areas; and computer-run, intelligent transportation systems. Future Automotive Technology and Fuels: The Options and Their Impacts While "too many of us use too much stuff too often," says John Heywood, cars may prove the worst commodity of all. They are responsible for a steady degradation of the ecosystem, from greenhouse emissions to biodiversity loss. What's worse, even if we improve vehicle efficiency, turn to fuel hybrids such as the Prius, or make rapid advances in hydrogen-based fuel technologies, the scale for slowing down the degradation may run to the decades. We have 130 million cars on U.S. roads right now, and add 15 million more each year. "Turning the curve won't be easy," says Heywood. "Human beings simply won't do as much as they can." Recommendations: an integrated policy approach, including better mileage standards and a stiff gasoline tax. |
