The utopia in Robinson’s Orange County Trilogy, with its self-sustaining communities, communal living, solar-powered houses, human-powered aircraft and so on. As his narrator (who is ‘writing’ the utopia from an internment camp where he is being held as a subversive) says, a society has irretrievably lost its direction when it cannot see the way to utopia from its current situation. There doesn’t seem to be a lot of sustainability in fashion at the moment, it’s true; not when an index of urban deprivation is ‘families without cars’, rather than ‘people without access to decent public transport’ (a rather higher figure, I surmise).
