My favorite disruptive technology is cars. There is a lot of oil for gasoline but it is obviously limited and causes a lot of pollution. People are always talking about the downside of cars but they never laud the great convenience and benefit of them because we take them for granted. The reason cars are not sustainable is that the level of pollution is too high and the supply of gasoline is limited. Perhaps with the introduction of new fuels
My favorite technology that is sustainable that I use is email. Although it is unkown if computers are sustainable the cost of sending an email is exponentially less than sending letter mail.
