Double-OWC Wave Power Extractor of a Taut Moored Floating Structure
A double oscillating water column is proposed as a means to improve the efficiency of wave power conversion over a wide range of wave periods in deep water. A mathematical model of the...

Use of Scrap Tires to Harness Wave Energy
A 2.5 meter diameter wave powered pump, fabricated from scrap tires was tested from May 24, 1988 to October 1988 in the Atlantic Ocean at the North Carolina Army Corp of Engineers Waterways...

The Development of Tidal Resources in China: The Tidal Experimental Station of Jiangxia and Its No. 1 and No. 2 Bidirectional Tidal Water Turbine
This article outlines the development and use of tidal energy, specifically, the exploitable tidal energy and the situation of its use in China and introduces the first large bidirectional...

Hydrogen Generation from Sea Water by Means of a Metal Hydrolysis Process
Active metals such as magnesium reacted with steam can produce hydrogen. This reduction of water by magnesium or aluminum is a thermodynamically favorable process, however, formation of...

Estimation of Wave Power as an Energy Resource for Hawaii
One of the most important elements in determining the wave power available by means of a wave power extracting device is the amount of wave energy present at a given location during a...

Conceptual Design of an Open-Cycle OTEC Plant for the Production of Electricity and Fresh Water in a Pacific Island
A plant, based on the Open-Cycle Ocean Thermal Energy Conversion (OTEC) concept, was designed to supply electricity and fresh water to a Pacific Island community. In order to boost fresh...

Conceptual Design Analysis for Hybrid-Cycle OTEC Plants for Co-Production of Electric Power and Desalinated Water
Hybrid-cycle OTEC power plants are shown to be potentially the most flexible and cost effective in obtaining any specific mix of electrical power and desalinated water. This paper describes...

Pre-Experiments of OTEC Experimental Facility for Ocean-Based Mariculture-OTEC Pilot Plant Houyou
The ocean-based mariculture-OTEC pilot plant 'HOUYOU' was completed in March, 1989 and the at-sea test in Toyama Bay was carried out from July 18th until September...

OTEC's subsurface discharges of Deep Ocean Water: Modelling Their Effects on the Primary Production
The French project of a shore-based OTEC pilot plant (5 MW) at Tahiti gave the opportunity of simulating the ecological effects of a small, man-made upwelling in coastal-tropical oligotrophic...

Overview: Steam-Water Phase Change in OTEC Systems
This paper presents an overview of the thermodynamics and the heat and mass transfer processes occurring in OTEC systems utilizing seawater as the working fluid....

Seawater Experimental Results of Direct-Contact Condensation for OC-OTEC Applications
Tests of a direct-contact condenser (DCC) for open-cycle ocean thermal energy conversion systems (OC-OTEC) have been conducted using seawater and exchanging up to 1.25 MW_th...

A Semi-Empirical Model for an OC-OTEC Spout Flash Evaporator
A phenomenological model for the thermal-hydraulics of a spout flash evaporator is presented in this paper. The model considers the two-phase flow behavior both in the spout and in the...

OTEC Sea Water Systems Technology Status
A workshop was conducted in April 1988 to provide an expert critique of the fabrication and deployment options for the seawater systems (all piping required to draw the seawater) of land-based...

OTEC Seawater Pipe Cost Comparisons
Describes a material which can substantially reduce the cost of seawater pipes and two methods for building and deploying such pipes for use in land-based OTEC installations, outfall sewers,...

Noncondensable Gas Composition and Outgassing Rates in the Open-Cycle OTEC System with Direct-Contact Condensation
This paper will present the results of recent measurements of noncondensable release from an open-cycle ocean thermal energy conversion (OC-OTEC) system in a direct-contact condensation...

Optimum Removal of Noncondensable Gases for Open Cycle OTEC System
For an open cycle OTEC system the dissolved gases in warm surface seawater are evolved in the flash evaporator. Those behave as noncondensable gases in the condenser and degrade the condensing...

De-Aeration and Re-Injection of Noncondensable Gases in Open-Cycle OTEC
Non-condensable gas exchange characteristics in seawater and fresh water are compared and contrasted. The higher rate of exchange observed for these gases in seawater is incorporated in...

Asphalt in the U.S. Transportation Infrastructure
Asphalt has been the major pavement material responsible for development of the transportation infrastructure enjoyed by American citizens. This paper addresses issues to be monitored...

Resin Transfer Process Modelling: Computational & Experimental
In most cases, the resin transfer molding (RTM) researcher has a fundamental understanding of composites and possibly some mold design experience. The areas of resin flow dynamics and...

Waste Geotechnics and Geosynthetics
The geotechnology related to waste management focuses around assessing the movement of water and pollutant transport, containment of the pollutant so that it is unable to pollute the underground...
