The Null Device
British architect Lord Norman Foster has just posited plans for a huge new airport and transport development on an artificial island in the Thames Estuary. The development, to be named the Thames Hub, will include the aforementioned airport, high-speed and standard-speed rail links to London, the Channel Tunnel and the North, a container port, an industrial zone and a new Thames flood barrier and tidal energy generator.
Foster (who, among other commissions, worked on Hong Kong's decade-old airport, which is also built on an artificial island), chided Britain for having lost its taste for ambitious projects:
"We need to recapture the foresight and political courage of our 19th-century forebears, " said Foster on Wednesday, "if we are to establish a modern transport and energy infrastructure in Britain for this century and beyond."The plan has won a number of high-profile backers: industrial designer Sir James Dyson, of vacuum-cleaner fame, has backed it, and Boris Johnson (who proposed an island airport in the Thames to replace Heathrow) is in favour. However, not everyone is convinced; there are concerns that the Isle of Grain, which is to be subsumed beneath the artificial island, is both a fragile bird habitat (which would be annihilated by the airport), and a huge natural gas depot (which would pose a hazard), with additional threats posed by a sunken US warship, laden with high explosives. Also, while plans for a new airport are partly motivated by London's airports being close to capacity, some are saying that this can be better mitigated by replacing short-haul flights with high-speed rail; if there aren't all those flights departing from Heathrow for Manchester or Amsterdam, there'll be plenty of capacity for places like New York and Hong Kong. (Of course, high-speed rail suffers from all the Anglo-Saxon aversion to big projects even more than an airport would, given that one would have to placate or defeat the NIMBYs at every step of the way.)
