A pipe dream?

..... or a possible means of fixing more CO2 out of the atmosphere?

Following on from the iron filings idea, this from James Lovelock and Chris Rapley suggests building hundreds of thousands of massive vertical pipes in the oceans. Each pipe would have a one way valve at the bottom so that wave action near the top would draw nutrient rich water up from the ocean depths, providing a spur to more algal growth, which it turn will fix more CO2 from the atmosphere.

The full article is reported in New Scientist.

Just one little snaglet might be the fact that "as well as being rich in nutrients, water rising up the pipes will be rich in carbon - this could mean CO2 is released into the atmosphere."

Oh well, it sounded like a good idea at first.

Yes, I suppose they 'could'. But as mans's meddling with nature is not quite working out at a success rate that's enviable, maybe it's more down to whether they 'should'.
