Good to see this energy harvesting

This is good to see, Elizabeth. I've heard from wind energy proponents that the real energy to capture is out on the ocean. There is more energy to grab on the water than there is on ;and.

I agree, Rob. If researchers can find a way to use winds offshore and the ocean itself, it could be an incredible sea change (pardon the pun) for the use of renewables as an energy source. This company is targeting islands initially, but I think this type of turbine could be used in other offshore applications as well. I'm thinking something like offshore oil rigs could be powered by this kind of wind turbine, for a start.

  While a good idea especially in the north sea, the selections of ineff rotors shows these people don't have a clue.  Nor is this a  new idea.

 

Facts are normal horizontal wind and water turbines/rotors are 2-3x's as eff as those shown, a fact of basic physics easily found out by anyone who tried.

 

They would have to build unit 2-4x's plus as large, cost for the same output makes this a non starter.

But what about the transmission lines-?

I am fascinated by this.  I've been intrigued with harnessing ocean current ever since an Electrical Engineering associate from our local power company was discussing turbines and the Gulf-Stream currents off Florida's coast. 

After looking into the article's content a bit deeper, I discovered some amazing things you didn't elaborate on, in the summary. First was that any good engineer ought to recognize the term, "Savonius" Turbine.  I, however, did not; I had to look it up. (Wikepedia is wonderful)  Second;  same thing for "Darrieus" Turbine. Had to look it up.  (No shame ! )

But what really threw me was that I completely missed the scale of the device in operation.  I hit MODEC's web site and downloaded their PDF on this which shows images in better detail and clarity. The floating yellow disc platform shown is actually about 100 feet in diameter! These "working" prototypes by MODEC are gigantic – near the size of Oil Drilling Platforms. I mistakenly depicted the apparatus as a garage-sized generator.

One sticking point I did not learn was, how is the power generated transferred to a user's location (on a remote island) ?

Thanks for reporting on this Elizabeth. What a cool combination of alternative energy technologies.

WIND TURBINE

I also visited their web site and was amazed at the physical size of the turbine/currents combination.  It's huge.  Not a toy.  Hopefully we can follow their progress as time goes by and get a look at data indicating actual power output.  I think alternate energy possibilities will become more important as time goes by and this device could, if successful, provide power to the most remote sites.  Great post Elizabeth.

It is quite an awesome-looking turbine, in terms of size and scale, I agree, bobjengr. And quite ambitious for them to tackle this. Ocean currents are a great resource if they can be harnessed by this and other new technologies.

You're more than welcome, Ann. Ocean-energy harvesting is a particular interest of mine, and I think it's really cool that a company found a way to combine current energy with wind--by using the energy to help power the turbine. It seems like just an initial step toward more widespread use of this type of energy as researchers get more creative with how they can leverage the sea and its potentially unlimited power source.

I didn't even know it was possible to harvest ocean wave energy until I came across the Wave Glider we've both reported on. That depends on a moving object doing the harvesting. If I recall correctly, earlier wave harvesting efforts were done with stationary harvesters. Is that right?

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
