Hunt for new technology

(Bob LLewellyn) #1

Someone said that new technology would change everything. So I thought that I would start a thread for new tech stuff as it applies to oceanic living. For the first one, I offer this.

There is this energy storage system that I have done research on, and it occured to me it could be ideal to be applied to a sea stead. I was reading over DeltaSync’s design plan, and a water depth of 10 meters was thrown around a lot, but there was no clear estimate of the desired bathymetry for the Floating City project. Does anyone know a round about figure for the depth of a sea stead?

During the Vietnam war, I serve on the aircraft carrier Coral Sea. She was roughly 1000 feet long and had a displacement of 35 feet (12 meters). It had a compliment of 4,000 men. It was cramped for a carrier but maybe that can give you an idea of a required minimum displacement depth.

I don’t recall where I saw it but I thought they said that the 10 meter location needed to be re-thought and 50 to 100 meter depths.

I am thinking they had a location picked out that they liked but the government was concerned about disturbing reefs or preserved areas so they had to look at locations further from shore.

Been thinking about the boat delivery idea and a boat is very inefficient when it comes to fuel, I was thinking about cable cars. What if we put a cable or small rail on stilts and had it pull a boat to the seastead? Could double as a sky lift. A 50 mile long sky lift, probably not feasible but something like that may haul a barge back and forth?

A junk rigged ketch doesn’t use very much fuel, easy to learn how to sail (junk rigging), almost impossible to over canvas (junk rigging), is a good working boat, and stable when going dead slow (ketch layout). Two or three light cargo boats could keep a village sized seastead very well supplied. No new technology required.

Doesn’t need to be a sailboat to sail.

(Sheldon Robertson) #10

Indeed. I have read about kites and sails to move rather large floating structures. Possibly a small or medium seastead. I was referring to resupply of a seastead when it is several hundred miles out. No need for diesel boats or cabled ferries.

Dynaponic soil-less farming

(Kurt Laipple) #12

Yes, skysails are for moving freighters, too.

(Jonas Smith) #13

Aeroponic systems will be key to growing produce on a seastead, and will help to reach a high level of self-sustainability:

(Kurt Laipple) #14

Dynaponics uses much less energy than aeroponics, but aeroponics can be used vertically more easily.

While everyone is discussing the bones of the city, here is something for the skin. Reduces drag, resists algae growth, and even reduces germs if used in a place that spreads germs like a hospital, pretty cool stuff.
