Autopia Ampere: The City From the Sea

Carbon Dioxide…it’s bad news, that stuff. Causing us no end of problems at the moment. But a lot of it gets absorbed by the sea. So why don’t we use it for something (literally) constructive? Autopia Ampere is the science fiction-esque dreamchild of a German architect called Wolf Hibertz. Using a technique called ‘mineral accretion building technology’, he plans to take the CO2 in sea water, turn it into limestone and build a city from it.

This isn’t as blue-sky as it may sound – the technology is proven and has been used to build reefs and landing pilings in the Caribbean. Simple electrolysis (passing current through electrodes) will cause calcium carbonate (limestone) to accrete around the electrodes. Once the hypothetical city is built, it will be able to support itself economically by growing limestone for shore-dwellers, all the while providing a great way of getting carbon dioxide out of the atmosphere and locked up somewhere it can’t make our environmental problems any worse. Sounds like a plan to me.

  1. Very interesting. I wonder how the construction would hold up under extreme conditions like hurricanes. I really love the sea so when you get it build let me know 🙂

  2. There is a new company called Skylifter that is creating a super blimp that can carry away 150 tons, so perhaps they could coordinate with this group to ‘grow’ entire BioRock houses in the sea, and use the blimp to transport them anywhere. It might be the cheapest new housing for the third world. Also, if they grow a city in the sea, why not make it mobile like a vast ocean liner, so that they can move the whole limestone-making industry closest to whoever needs the BioRock seacrete construction panels and other parts the most?
