No Food, No Utopia: How Will Floating Cities Survive? | Big Think

TL;DR

Engineers are developing small pilot seasteads, built as multiple smaller platforms within deep lagoons to avoid shadowing and environmental impact. Although not fully self-sustaining, seasteads explore innovative technologies such as cold agriculture, algae, lab-grown meat, and vertical farming for food production.

Transcript

The pilot project is quite modest. So before we go out and build huge floating structures for hundreds and thousands of people we’re building a small pilot which will be about the size if you can imagine a soccer field—It’s around 7500 square meters. The engineers are saying it shouldn’t be a single platform, it should be multiple smaller platforms... Read More

Questions & Answers

Q: What is the rationale behind developing smaller platforms for the seastead pilot?

The smaller platforms are necessary to avoid shadowing and impact on photosynthesis in the lagoon. By having multiple smaller platforms connected by bridges, light can penetrate the water, minimizing the environmental impact.

Q: What technologies are being explored for food production on seasteads?

Technologies such as cold agriculture, algae farming, and lab-grown meat are being considered. Cold agriculture utilizes deep ocean water to create condensation for plant irrigation, while algae farming offers various consumable options. Lab-grown meat is a recent technology that can provide alternatives to traditional livestock farming.

Q: How will fresh water be sourced on the seasteads?

Fresh water will be sourced through rainwater catchment using the roofs of the seasteads. Additionally, innovative technologies are being developed for low-energy desalination to supplement the fresh water supply.

Q: What innovative techniques are being explored for efficient food production?

Vertical farming with UV lighting is being considered to optimize space utilization, with some companies claiming the ability to produce a million pounds of food per acre per year. NASA-developed nanotech is being investigated for its ability to modify the wavelength of light to enhance plant growth.

Summary & Key Takeaways

• The pilot seasteads will be small and consist of multiple platforms in deep lagoons to avoid environmental impact.

• While the seasteads aim to be self-sustaining in terms of energy, water, and waste management, they won't achieve complete self-sufficiency in food production during the pilot phase.

• The project explores various technologies such as cold agriculture, algae farming, and lab-grown meat as alternatives to traditional farming methods.

• Vertical farming with UV lighting and NASA-developed nanotech are also being considered for efficient food production on seastead platforms.
