ocean currents as alternative energy

Ocean currents are also gaining significance as a possible form of alternative energy. Because water is dense, it carries an enormous amount of energy that could possible be captured and converted into a usable form through the use of water turbines. Currently this is an experimental technology being tested by the U.S., Japan, china, and some of the European Union countries.

Whether ocean currents are used as alternative energy, to reduce shipping costs, or in their nature to state to move species and weather worldwide, they are significant to geographers, meteorologists, and other scientists because they have a tremendous impact on the globe and earth-atmosphere relations.

I learnt that it reduce shipping cost by changing the ocean current and that the currently this is an experimental technology being tested.

With ocean current is all pulls some where normally towards the land.

I wonder how people use water in turbines.

Ocean Currents

What is an ocean current?

Ocean currents are vertical and horizontal movement of the two surface and the deep water throughout the worlds oceans. Currents normally move in specified directions.

Oceanic currents are found all over the world in many sizes.
Some of the prominent currents are found in California and Humboldt currents of the pacific, the gulf stream and the Labrador Current in the Atlantic.

Surface currents are those found in the upper 400 meters or 1,300 feet of the ocean and that make up about 10% of the entire worlds ocean.

Mitrochondrion and Chloroplasts

Mitrochondrion provides the energy for the cells. They are the power center of the cell, they are about the size of bactria

but may have different shapes depending on the cell. The cristae greatly increase the Inner membranes surface area.

Chloroplasts are specialized organelles found in higher plant cells these oganelles contain the plant cells chlorophyll, hence provides the green color. They have a double outer membrane. Within the stroma are other membrane structures the thylakoids and grana
(singular = granum) where photosynthesis takes place

Cells

Cells they are a living organism we use micro scopes to zoom in on different cells we use electron micro scopes and compound lights micro scopes anton van leeuwenhoek made the first light micro scope in 1940 compound microscopes uses series of lences to magnify objects cells are a basic building blocks of all living things way is funny is people a long time ago before there were microscopes people believed that disease were caused by cures and supernatural spirts 1. oganism are made up of 1 or more cells 2.cells are a basic unit of organisation of organisms 3. All cells come from preexisting cells
