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. 接更多條的交流電線或超導線可以增加傳輸容量，但出問題時也會在電力輸送網內引成更大的漣漪。
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. 技術進步的特點是大幅度提升了的信息儲存與處理的速度容量和功能，以及成本更為低廉的傳播能力。
