Summary:

Several novel configurations of mobile oceanic renewable energy systems are presented with emphasis on advantages over existing planned offshore development. Consideration of certain historic weather and levelized cost of energy data indicates profitable operation for various configurations presented. Optimized configuration, maintenance and operation, and navigation of one or a fleet of modularized mobile buoyant structures utilizing wind, wave, heat, and electrical co-generation to produce any of a variety of commodities or environmental remediation reagents such as but not limited to hydrogen fuel (compressed or stored in a hydride), charged batteries, oxygen, ammonia, lye, bleach, concentrated saline - sea salt, pure water, any mineral or compound electrochemically or thermo-chemically isolated from seawater, and delivery of these products in and from an offshore environment, exists as a fundamentally disruptive innovation. Through novel simultaneous exploitation of wind, solar, and hydrokinetic resources, the mobile structures expedite installation and facilitate maintenance; and eliminate, mitigate, or circumvent existing risks and costs associated with resource intermittency, storage feedstock scarcity, regulatory delays, aesthetic objections, and land-use restrictions. One class of mobile structure uniquely prospers from severe weather conditions.
