Assault on batteries: At that time the development of the electric car was helped from behind the scenes by the highly efficient electronic parts and technologies discovered in the American Apollo program to reach the moon, so there were major accomplishments. But there seemed no way to break through the obstacle of battery capacity imposed by nature.
小電池，大問題當年電動車的發展，由於有一九六○年代、美國阿波羅探月計畫開發出的許多高功率電子元件及技術在背後支持，而有相當成就，但卻無法突破電瓶容量的先天限制。
