As an engineer, I care for my work efficiency. When traveling, particularly flying, I could not help but feel stressed for losing so much work time.
Much more so, the time abroad attending conferences and various meetings was usually unfruitful. Even personal contacts made were of no more substance than contacts made by e-mail, which are accompanied by a thorough exchange of information. Necessary geo-data and other information required for my scientific models is all available on the internet. Traveling never gave me access to better information.
My civil engineering bureau develops concepts, prototypes, and technologies for self-sufficient buildings and settlements.
