TL;DR: In this paper, a case study on the Florida currents between Miami, Florida and Bahamas is presented, where a region of 60 km × 10 km × 200 m power in the range of 22 to 37 GW is predicted to be produced at about a cost of 1.1¢ per kWh.

TL;DR: In this paper, a computer simulation method for predicting the dynamic responses of a marine power system containing both AC and DC subsystems is proposed, which allows modelling of system components in modular form and representation of network relations by utilising Kirchhoff's current law, hence providing flexibility in model building and testing.
Abstract: A computer simulation method for predicting the dynamic responses of a marine power system containing both AC and DC subsystems is proposed. The method has two important features. First, it allows modelling of system components in modular form and representation of network relations by utilising Kirchhoff's current law, hence providing flexibility in model building and testing. The second feature is its ability to simulate the performance of DC machines and converters in a combined AC/DC system. The paper contains a description of the method and its application to a practical marine power system. Simulation results are practically verified by comparing with a manufacturer's supplied experimental data.

TL;DR: In this paper, an open-cycle ocean thermo energy conversion (OTEC) device is described, which uses a penstock to drop warm salt water entrained with air down a pen stock to drive a hydroelectric turbine generator.
Abstract: A patented hydro-well invention is described that falls into the classification of an open-cycle ocean thermo energy conversion device. The apparatus drops warm salt water entrained with air down a penstock to drive a hydroelectric turbine generator. The salt water is cooled by the ocean sump and becomes heavier than the ambient water. The air is compressed hydraulically and separated to create a second work force. The forces, together with salinity, work to exhaust the water. The invention consumes no fossil fuel, does not pollute, and has the potential to furnish most of the world's electric needs without subjecting people to radiation. The US Department of Energy (DOE) has estimated that a mechanism of 2 MWe can be built at a cost of $7200/kWe. Using the same cost basis, a 2-MWe hydro well could be built for $1345/kWe because it is only 1/3 as deep and handles 1/8 the amount of water of conventional OTEC devices. >

29 Jan 1988TL;DR: The state of the art of ocean energy recovery activity in the United States is described in this paper, including extraction of wave, tidal, ocean thermal and ocean current energy, and an assessment of potential benefits and potential problems that might be encountered.
Abstract: The state of the art of ocean energy recovery activity in the United States is described. The technologies discussed in the paper include extraction of wave, tidal, ocean thermal and ocean current energy. This status report is intended to provide a description of the various ocean energy technologies and an assessment of potential benefits that might be expected and potential problems that might be encountered.
