Nexus: Mobile Floating Sea City
Anywhere in the world

Project Owner: Individual and Corporate Sponsorship. Privately owned as a cooperative community. Each inhabitant pays a small percentage of the total cost. For a population of 50,000 people this requires an investment of approximately $100,000.00 to $200,000.00 A loan/payback plan might be initiated whereby individual loans are taken out by each individual and is then paid back from money made by the community after it is a going concern. Interested organizations would act as lending institutions to cover the initial costs. Possible sponsorship might come from corporations such as Lucasfilm, Walt Disney Productions, Amblin Productions, Microsoft and other tourism or technology-based companies.

Due to the inevitable appeal of such a community as a tourist attraction the return on initial investment are dependable. Disneyland, DisneyWorld and EPCOT Center are popular examples of this phenomenon.

Imposed financial limitations would require that any person wishing to "sell" their ownership in the cooperative community must not sell for profit. That is, the selling price must be equivalent to the initial purchasing price plus inflation, etc. This will help to prevent the community from becoming a real estate profiteering enterprise.

Location: Built in the calcium-rich coast line of the southeast Asian countries by a consortium of international builders.
Date: 1986
Cost: 10 billion US dollars
Population: up to 50,000 people
Approximate Dimensions: 4.7 miles long by 2.5 miles wide (7.5 Kilometers long by 4 kilometers wide)
Surface Area: 22 Square Kilometers (5,335 square acres)

This is a floating city designed to accommodate 100,000 persons. 7 kilometers long and 4 kilometers wide with the capacity to be mobile, grow its own food, produce its own electricity and, owing to it existing beyond the 12 mile governmental jurisdiction boundaries, create its own government, income system and tax base. In essence, this mobile city becomes its own independent country. The structural material for the project is electrolytic concrete made from seawater mineral salts that adhere to steel rebar submerged underwater with a small amount of electrical current applied to the bar. Over a short time the mineral salts from the seawater accretes onto the steel to form a concrete material. The process is extremely inexpensive and produces reinforced concrete suitable for creating structures. The structure is built underwater and is then floated to the surface when completed. The city utilizes several different types of electrical power generation. Five Ocean Thermal Energy Conversion units are positioned at strategic zones of the city to supply electricity. Banks of freestanding windmills and photovoltaic solar cells produce additional electricity. The "head" of the floating city is a small mountain range with a specially designed frontal structure that cuts Tsunami tidal waves into smaller, manageable waves with little destructive effect. It is a tidal wave barrier that requires the city to head into the on-coming wave. An adjustable set of hydrodynamic "limbs" adapts to the needed amount of marine agriculture garden area depending upon population needs. The "limbs" also reduce water drag when positioned together. The greatest advantage to the city's mobility is that when it rests in one place for a while to exploit the ocean's resources it can then move onward so that that particular area is not depleted and can replenish itself thus protecting and preserving the ocean's bounty. The city grows its own food and is an agrarian-based population utilizing advanced, nature-based technologies that produce no toxic pollutants. "Living Machines" and solar desalination plants create and recycle all water for human use. The city, in essence, is a living organism based upon ocean resources and climate.

Economic Sources: Tourism, marine research exploration, nautical vessel design and production, exportation of sand and ballast dredging, mineral and metal dredging i.e., salt, magnesium, pharmaceuticals, dyes, strontium (used in fireworks, flares, etc.), Rubidium (used in photoelectric cells), copper, manganese dioxide and gold, fertilizers manufactured from seaweed and sewage, distilling plants to provide fresh water to the mainland, fresh water to turn formerly arid lands, on the mainland, to orchards and gardens, exportation of fresh water to distant areas on the mainland, fish farming (fish have extremely high conversion ratio of feed consumed to meat produced); fish feed can be processed from waste products, i.e., sewage, and yield of fish produced from fish farms should equal, if not exceed, the productivity of any warm-water pond; seaweed production, scientific and technological inventions such as portable sea water-to-fresh water distilleries, more efficient photovoltaic cells, improved mariculture techniques, improved windmill design, new kinds of undersea exploration vessels, new developments in boat and floating home designs, etc.

Suitable Areas of existence: Southern California coast, southeast coast of Massachusetts (Martha's Vineyard), the Yellow Sea, the East China Sea, off the coast of Israel, the Persian Gulf, the South American coast below Rio De Janeiro, the Gulf of Mexico, the Java Sea northward to the Gulf of Siam, the Baltic Sea and the northern half of the Adriatic sea between the coasts of Italy and Yugoslavia.

Public Transportation Systems: "Maglev" electromagnetic high speed train and underwater "subway" system; Aerotaxi (flying and floating taxi vehicle capable of holding thirty persons), nautical taxi capable of high speed and undersea travel (12 to 100 person capacity depending upon size of vehicle).

Private Transportation: Four person jet-air flying platform, amphibious hovercraft vehicles, sailing craft and nautical vehicles and pedal vehicles.

Transportation To and From the Sea City: "Ringwing" jumbo passenger turbofan jet, vertical take-off turbofan jets, high speed passenger ferry and privately owned nautical vessels.

Sea City Propulsion: Twenty seven turbo electric drive water-jet/contra-rotating propeller engine system. System is attached to a Pelton water turbine so that electrical power is recycled into main electrical supply generators thus creating its own electrical energy with minimal power loss.

Range of Speed: 1 to 5 Kilometers per hour.

Judicial System: Given that the Nexus Mobile Floating Sea City Community exists outside the twelve mile boundary of all governing national jurisdictions Phase I of the project will contain approximately 10,000 to 15,000 persons who will act as an experimental; group to lay down the founding laws and principles of the city. Because the overall community is made of several very small neighborhood communities each community might wish to develop their own ways of evolving laws.

Studies have pointed out that there is a strong tendency for crime to develop in circumstances where individuals feel a lack of relationship with the community due to the large size of the community. When a community is very small and each person feels a kinship with others in the community crime is usually minimal. This phenomenon is enhanced and strategically applied to the formation of communities of the Nexus Project.
