Power peaks against installed capacity in tidal stream energy
IET Renewable Power Generation, 2013 Owing to the natural variability of tidal flow, the curve of available power against time at the site of a tidal stream plant is typically spiky. This means that, for the power peaks to be fully exploited, the installed capacity of the plant would have to be large relative to its mean power output.

Incorporation of a Non-Constant Thrust Force Coefficient to Assess Tidal-Stream Energy
Energies, 2019 A novel method for modelling tidal-stream energy capture at the regional scale is used to evaluate the performance of two marine turbine arrays configured as a fence and a partial fence.

Quantification of the tidal stream exergy in the ría de Vigo (NW Spain) [PDF]
, 2017 The exergy of the tidal currents in the ría de Vigo area (NW Spain) is quantified using the results of a 28-day long simulation of the tidal flows. The results show that the northernmost strait connecting the ría with the Atlantic Ocean is a promising ...

Misplaced fears? What the evidence reveals of the ecological effects of tidal power generation
Ecological Solutions and EvidenceTidal energy is a dependable and clean power source that stands as a compelling alternative to fossil fuels. Despite this promise, tidal energy projects face barriers to practical implementation, and objections to proposed schemes often stem from ...

The Giant X-Ray Flare of NGC 5905: Tidal Disruption of a Star, a Brown Dwarf, or a Planet? [PDF]
, 2002 We model the 1990 giant X-ray flare of the quiescent galaxy NGC 5905 as the tidal disruption of a star by a supermassive black hole. From the observed rapid decline of the luminosity, over a timescale of a few years, we argue that the flare was powered ...

Direct Detection of Dark Matter Debris Flows
, 2012 Tidal stripping of dark matter from subhalos falling into the Milky Way produces narrow, cold tidal streams as well as more spatially extended "debris flows" in the form of shells, sheets, and plumes. Here we focus on the debris flow in the Via Lactea II

On the Stability of Tidal Streams [PDF]
, 2011 We explore the stability of tidal streams to perturbations, motivated by recent claims that the clumpy structure of the stellar streams surrounding the globular cluster Palomar 5 are the result of gravitational instability.

Theoretical limits to tidal stream energy extraction
, 2016 Tidal stream energy has gained attention as a source of predictable and renewable energy. Devices resembling underwater wind turbines, placed in fast tidal streams, have been proposed to extract this energy. Arrays of many such devices will need to be deployed to deliver a significant amount of energy to the electricity grid.

Can Tidal Current Energy Provide Base Load?
Energies, 2013 Tidal energy belongs to the class of intermittent but predictable renewable energy sources. In this paper, we consider a compact set of geographically diverse locations, which have been assessed to have significant tidal stream energy, and attempt to ...
