#22The real question is if we are changing a very productive system for a not soo good one. Octopuses growth much quicker than strawerries, and are also more expensive. Any aquaculture system in the same area will provide much more human food and better revenues (you are using a 3d volume for production instead a 2d surface). Marine soil is not apt to cultivate, so you need to put terrestrial soil underwater (or hydropo…

Octopuses are some of the smartest animals. Not a vegetarian, but I can't eat one. It's like eating a monkey.

If you want to have any opportunity with underwater "put-some-activity-here" you absolutely need to have a way to put all your stuff safely out of the sea before a gale or a strong storm. I will not recommend to invest a single cent in underwater permanent activity that do not have a solid plan B for bad weather days.

#25Maybe I'm missing something, but I don't see what being under the ocean has to do with anything? You can get humidity in a simple greenhouse, and there is no more CO2 in air exposed to the ocean than there is in ordinary air.

Octopi would need food to live and that food is a huge cost in resources. Octopi consume a feed that could have been human to begin with. Plants need only water and reused plant material or any other natural fertilizer.

The dangers in sending down divers to pick strawberries alone make it not practical as a business.

Trust me, you will notice it. River deltas are made of sediments and carry heavy stones and trunks for several km after a strong storm. Even the slightest flood will nuke your small underwater plastic balloon and carry the remains many miles offshore. If you want to have any opportunity with underwater "put-some-activity-here" you absolutely need to have a way to put all your stuff safely out of the sea before a gale…

#30"The company is also planning to launch a crowdfunding campaign next week to support further development." Why would a CEO wait till the week after an article with this many readers to launch such a campaign? Surely he could have launched it before this article?
