A variation to the hydroponic sachet idea.. Having a plant independently packaged in a floating container which can interlink with others to create a large raft. The water could be obtained from the sea using solar power (see link below) and if a storm is brewing they could be floated off to another location.

Hey, this could grow big and there sure is a lot of space on the oceans. I love it!+

So long as keeping light out of the oceans is still a good idea.

I know security would be a concern, but these would be great places to spearfish under.

We could create a wide range of biodiversity by planting different species in certain parts. For example, in the middle where fresh water would be more rare we could plant saguaro cacti, then put some Sequoias along the western edge. Then we could name it The Great Sequoia Saguaro Sargasso Seafarm.

If you planted mangroves, you wouldn't need to desalinate the water.

I've considered this before, then thought of semi-floating coral reefs, then thought of floating algae trays. I now think that trees in the desert, watered by solar powered condensers would be best.

I was also looking at the new machines used to generate power from the waves, maybe tidal would work better then just plain solar power.

Cool. It may help cool the oceans somewhat. That wouldn't be a bad thing.

//Cress. Lots of it.//

Whitening or anti-cavity? Gel or paste?

In the same vein as the 'oceanic gardens' idea... I'm more looking for a very modular compact design so that expansion won't be a headache. I do like cress as well :)

I don't understand why to do it. Growing trees with water and nutrients won't be buoyant enough nor self-sufficient. The cost of the infrastructure (boat?) should be offset by the benefit of the structure-thing.

Wouldn't algae provide a lot of the benefits mentioned regarding cooling or keeping light out of the oceans.
