The space hosepipe
Now, you've all heard of the space elevator, a proposed structure anchored to the surface of the Earth, extending upwards through the atmosphere and into space? (en.wikipedia.org/wiki/Space_elevator) Well, now comes the space hosepipe, suggested by Jeremy Clarkson as a means of mitigating rising sea levels: www.timesonline.co.uk/newspaper/0,,176-2580397,00.html. Jeremy suggests that if we had a giant hose dipped into the sea at one end, and extending up into the vacuum of space at the other end, then the pressure difference would cause the water to be sucked up the pipe, against the force of gravity, and expelled into space. I haven't worked out if the pressure difference would be sufficient to overcome the force of gravity, but it's surely worth a go isn't it?
