Green energy? What about trying a little blue energy for a change? Blue seems just as wholesome and non-threatening, right?

In a similar vane to my last post on algae the geniuses of the world have come up with another truly brilliant "why didn't I think of that" kind of idea. It seems to make so much sense! It's so big ... and powerful ... and blue ...

Engineers at Blue Energy have developed, with support from the Army Corps of Engineers a turbine for the ocean. No no, not a wind turbine ON the ocean (my mom just made that mistake) but an underwater turbine that will harness the powerful ocean currents to create possibly the most sustainable energy source we know of!

Here is what we know: Water turbines will be placed in the Gulf Stream near Florida and they will work much like land wind turbines (using a rotater blade, which when made to spin by wind or water, creates energy!).

There is still a considerable amount of work to do before water turbines can be utilized. Frederick Driscoll, director of Florida Atlantic University's Center of Excellence in Ocean Energy Technology strives to be realistic about the future of water turbines. A resource assessment of the Gulf Stream is underway to help understand exactly how much energy can be safely extracted from the ocean, where exactly it should be extracted from and how to get the energy safely and efficiently to our homes without disrupting the ocean environment. So much to think about!

Florida is the fourth largest state in the U.S. and the third largest consumer of energy. They are in dire need of a new energy source as many experts insist that Florida is on the brink of a very serious energy crisis. Much still needs to be done in the way of turbine technology in order to move ahead with incorperating them into the fleet of renewable energy sources. This past spring four acoustic Doppler current profilers were lauched off the coast of Florida to gather information about the currents, mainly to learn about the speed of the ocean currents. Ocean energy may become the crown jewel of the fleet.
