Innovative on-Shore System recovering Energy from Tidal Currents

Energy Procedia, 2017
Abstract An innovative system for the recovering of energy from tidal currents is proposed. The system is composed of a blade submerged in sea waters and connected to a vertical bar which, moving up and down through the tide action, transfers energy to a double effect piston pump.

Potential Hydrodynamic Impacts and Performances of Commercial-Scale Turbine Arrays in the Strait of Larantuka, Indonesia

Journal of Marine Science and Engineering, 2020
The Strait of Larantuka, with highly energetic tidal stream currents reaching speeds of up to 3−4 m/s, is a promising site for renewable electricity production from the ocean. This paper presents the results of an assessment regarding the potential

Modeling Evaluation of Tidal Stream Energy and the Impacts of Energy Extraction on Hydrodynamics in the Taiwan Strait

Energies, 2013
Tidal stream speeds in straits are accelerated because of geographic and bathymetric features. For instance, narrow channels and shallows can cause high tidal stream energy.

TIDAL CURRENT ENERGY AN OVERVIEW

International Journal of Research in Engineering and Technology, 2015
Ocean currents are an enormous source of green energy. This energy from marine currents can be extracted by means of tidal turbines. This paper explains different types of tidal current turbines. This paper discusses about tidal energy and site selection criteria for tidal current turbine in general.

Tidal current energy resource assessment in Ireland: Current status and future update

Renewable and Sustainable Energy Reviews, 2010
Interest in renewable energy in Ireland has increased continually over the past decade. This interest is due primarily to security of supply issues and the effects of climate change. Ireland imports over 90% of its primary energy consumption, mostly in the form of fossil fuels. The exploitation of Ireland's vast indigenous renewable energy resources is

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

Advanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, EarlyView.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...
