Ocean Energy: Using the Ocean's Tides, Waves, and Heat to Generate Electricity [PDF]

open access: yes, 2006
Key facts: - The oceans' tides, waves, current, and heat can be used to generate electricity. These resources are renewable, because the moon's gravity drives tides, and winds create waves.

Numerical Research of the Effect of Surface Biomimetic Features on the Efficiency of Tidal Turbine Blades

open access: yesEnergies, 2018
Horizontal-axis axial flow tidal current turbine is regularly used to exploit the kinematic energy in tidal currents. However, the scaling up of tidal current turbine is very difficult.

Future archaeologies : method and story. [PDF]

open access: yes, 2009
This will be an account of an ongoing experiment called 'future archaeology'. Despite it’s name it's not strictly an archaeological experiment, since I’m not an archaeologist. Nor is it strictly scientific, since I’m not a natural scientist.

The downstream wake response of marine current energy converters operating in shallow tidal flows

open access: yes, 2011
This paper presents findings from an experimental study investigating the downstream wake response from marine current energy convertors operating in various degrees of vertical flow constraint. The paper investigates deep vertically unconstrained sites,

Sequential Design for Computer Experiments with a Flexible Bayesian Additive Model [PDF]

open access: yes, 2012
In computer experiments, a mathematical model implemented on a computer is used to represent complex physical phenomena. These models, known as computer simulators, enable experimental study of a virtual representation of the complex phenomena ...
