Mobile Wave Energy Harvesting System
Conventional approaches to harvesting energy from ocean waves and currents suffer from at least three major drawbacks: 1) expensive underwater power transmission cables, 2) storm damage susceptibility, and 3) energy output is not delivered at [...]
Offshore Wave and Wind Together – Afloat
Offshore wind and wave power are, or can be, remarkably complimentary. Given a stable floating platform to share, important economies of renewable power production and storage are possible. (A figure shows how wind and wave [...]
Offshore Renewable Resources – Improving the Cost-of-Energy
The U.S. has an abundance of wind and wave offshore resources suitable for industrial-scale power generation, the best resources are in deep waters. Cost-of-Energy (COE) is defined as Production Facility’s Total Costs (C) divided by [...]
Process-Fluid-Lubricated Polycrystalline Diamond Bearings for application in Marine Hydrokinetic Machines
Polycrystalline diamond thrust and radial bearings have proven to be successful in harsh environments, such as those encountered in down-hole oil and gas drilling tools. They are particularly well suited for applications where a harsh [...]
High-Power-Density Miniscale Renewable Energy Systems
This paper reports design, analysis, evaluations and characterization of miniscale self-sustained power generation systems. Our ultimate objective is to guarantee highly-efficient mechanical-to-electrical energy conversion, ensure premier wind- or hydro- energy harvesting capabilities, enable electric machinery [...]
Wind Mechanical Engineering: Energy for Water Pumping in Rural Areas in Sudan
The imminent exhaustion of fossil energy resources and the increasing demand for energy were the motives for those reasonable in Sudan to put into practice an energy policy based on rational use of energy; and [...]
Expermental Study of CH4/H2 Mixtures in Internal Combustion Engines
In this study, an experimental study on the performance of a spark ignition engine fuelled with CH4/ H2 mixtures (90%CH4 +10%H2 and80%CH4 +20%H2)was performed at different engine speed and different injection timing coefficient (ITC). This [...]
A Smarter Grid enables Communal MicroGrids
As policy makers seek to integrate a serious sociological and environmental issue into energy production, the typical utility is faced with not only technology upgrades, but also dealing with new systemic events that occur far [...]
Vertical-Axis Wind Turbines for Powering Cellular Communication Towers
A vertical-axis turbine has been designed to power cellular communication towers. The turbine’s design is specifically focused on providing continuous power to manage the tower’s electronics without interfering with the tower structure. The design of [...]
