ABSTRACT
Human society is highly dependent on the existence and use of technical transportation devices. Goods are transported long distances by large cargo ships or by airplane. People commonly use trains, buses or commercial aeroplanes for personal transport. Technical transportation vehicles allow for longer and faster movement than would be possible by foot or on horseback. Th us, cars, trains, boats and aeroplanes result in effi ciencies in speed and ability to carry cargo, benefi ts that have seemingly led society to depend on these tools to maintain its current standard of living. Th is need for effi - ciency brings about a search for something that is more effi cient than humans themselves: we strive for the possibilities and promises provided by technology.
