Abstract 报告摘要

The Story of Currents: AC versus DC

- a taste of industrial logic behind destructivetechnology in history -

从直流电和交流电的故事看颠覆性科技诞生的产业逻辑

When the electrical systems were invented, it was not easy to decide if alternating current (AC) or direct current (DC) will power the modern world. The genius inventors and industrialists behind these electrical systems - with Thomas Alva Edison (DC) on one side while George Westinghouse and Nikola Tesla (AC) on the other - were in a race to show that their electrical system is better than others. There is a whole dramatic story behind this struggle that shows how humanity moved from darkness to brightness and how the passion of different people shaped this world. This talk will discuss the struggle between these two groups of inventors who brought the disruptive technology of current into our brightened world and show who emerged as the winner. This story also shows the persistence, hard work, and entrepreneur ship of these inventors/scientists that can be learning experiences of seeking and incubating disruptive technology for the new generation.

当电力系统刚被发明之初，社会很难确定到底应该采用交流电（AC）还是直流电（DC）为世界提供电力。这些电力系统背后的天才发明家和实业家们：一方以托马斯·爱迪生为代表的直流电拥护者，另一方面是乔治·威斯汀豪斯和尼古拉·特斯拉为代表的交流电拥护者，竞相证明他们的电气系统比另外一方更加优越。这场斗争背后有一个完整的戏剧性故事，展示了人类如何从黑暗走向光明，以及参与其中的不同人的激情及他们如何塑造了这个世界。本次演讲将讨论这两组发明家之间围绕给社会带来光明的电流这一颠覆性科技早年的科技和产业斗争。故事里展示了诸多发明家和科学家的坚持，他们的努力工作和企业家精神，故事为我们寻找颠覆性科技的诞生机制提供了可以借鉴的经验和探索的路径。
