Installing more AC lines or more powerful superconducting lines alone would increase transmission capacity but could lead to bigger ripples in the grid if something went wrong. 接更多条的交流电线或超导线可以增加传输容量，但出问题时也会在电力输送网内引成更大的涟漪。
Technology progress is distinguished by immensely increased speed, capacity and functionality for information storing and processing and by the ability to transmit at lower cost. 技术进步的特点是大幅度提升了的信息储存与处理的速度容量和功能，以及成本更为低廉的传播能力。
