I cam up with this idea after reading about Anti-plastic Submarines and floating farms on here. After commenting on them, I thought: why not man them and live a nomadic lifestyle? Each colony would have a farm greenhouse on, and a means to gather plastic, as well as homes. In addition, it would contain in itself somewhere to construct other craft from the waster it collects.
I expect they would grow at an exponential rate, clearing up the ocean and providing a home to humanity at the same time. Given that the greenhouses are filled with air, they could potentially act as submarines if the need arises (e.g. a particularly bad storm.
The basic idea - living on the ocean - appears to be baked, and it's called Seasteading.-- Selky, Aug 18 2009 Oceanic Agriculture Oceanic_20Agricultu...0Island_20States_5dThe Halfbakery idea for ocean agriculture. Sounds like it could work. [Selky, Aug 18 2009] Anti-plastic submarines Anti-Plastic_20SubmarineThe submarines I mentioned. A bit more far fetched, but man them and it will be okay.

They'll be some way around the problem, I bet.-- Selky, Aug 18 2009 random, halfbakery
