The image to the right illustrates the high density of flow along the coast, note the high velocity white northward flow, perfect for extraction of ocean current energy. Countries that are interested in and pursuing the application of ocean current energy technologies include the European Union, [4] Japan, [5] the United States, [6] and China. [7]
Ocean currents are instrumental in determining the climate in many regions around the world. While little is known about the effects of removing ocean current energy, the impacts of removing current energy on the farfield environment may be a significant environmental concern. The typical turbine issues with blade strike, entanglement of marine ...
U.S. patent 3,928,967 — 1974 Apparatus and method of extracting wave energy – The original "Salter's Duck" patent; U.S. patent 4,134,023 — 1977 Apparatus for use in the extraction of energy from waves on water – Salter's method for improving "duck" efficiency; U.S. patent 6,194,815 — 1999 Piezoelectric rotary electrical energy generator
Precipitation [mm/day] over the ocean, averaged over the time period 1987–2014. Data from: Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite Data - HOAPS 4.0 [5] The actual freshwater flux that the ocean experiences in a certain timeframe is the net amount of precipitation and evaporation in this time interval.
A geostrophic current is an oceanic current in which the pressure gradient force is balanced by the Coriolis effect. The direction of geostrophic flow is parallel to the isobars , with the high pressure to the right of the flow in the Northern Hemisphere , and the high pressure to the left in the Southern Hemisphere .
But did you know that even when they're turned off, appliances and electronic gadgets gobble up energy, costing you money? The average U.S. household spends about $1,900 a year on energy costs ...
Knowledge of surface ocean currents is essential in reducing costs of shipping, since traveling with them reduces fuel costs. In the wind powered sailing-ship era, knowledge of wind patterns and ocean currents was even more essential. Using ocean currents to help their ships into harbor and using currents such as the gulf stream to get back ...
