Please correct me if I am wrong and just missed it while reading: but while reading The Windup Girl, I thought that it was strange that with all the technologies they had to genetically modify the seeds to be resistant to the plagues and the megodont that they still used springs to store energy. I just believe that there would be a more efficient way for them to store power then having to constantly rewind the springs. I may have just read over why it’s this way. Do any of you have any thoughts on this?
