Comments on: Underwater Ocean Turbines Will Generate Renewable Energy http://inhabitat.com/underwater-power-generating-ocean-turbines/ Green design & eco innovation for a better world Wed, 19 Jun 2013 21:48:15 +0000 hourly 1 http://wordpress.org/?v=abc By: teo2 http://inhabitat.com/underwater-power-generating-ocean-turbines/comment-page-1/#comment-228490 teo2 Thu, 27 May 2010 05:35:15 +0000 http://www.inhabitat.com/2007/12/10/underwater-power-generating-ocean-turbines/#comment-228490 do you knows what a return siphon is? small description: we put a Turbine on the sea-bottom and it must be into a frame-housing.throught the top of this, falls the water into the Turbin-room and move it, revolving and increasing speed. the water get down into the centrifuge. the on this area begining pressure will be throught the outlet pipe to the surface sended. If you like this design, call for more abut to. don´t be the last. do you knows what a return siphon is? small description: we put a Turbine on the sea-bottom and it must be into a frame-housing.throught the top of this, falls the water into the Turbin-room and move it, revolving and increasing speed. the water get down into the centrifuge. the on this area begining pressure will be throught the outlet pipe to the surface sended.

But i also believe we should go through with this and conserve energy! I believe that weare basically killing ourselves by global warming and by using way tomuch energy!

Yes we are taking a renewable source but what about the ecosystem upstream. With enough of these I would imagine it would weaken the current to a certain degree. With extended use it could have huge impacts. Look at global warming and the impact that a few degrees increase has. The gulf stream is a vital source for ocean circulation and weakening it to any degree will eventually have consequences. I am all for this though as an ocean engineer but there are a few details that we still need to consider. (I have to agree with everyone who says that the marine life will not affected but the turbine blades themselves. They would be movng at a slow speed and the concentration is on torque not speed. If anything we would have to worry about marine life messing with the turbines.) The biggest concern should the impact on the stream after the turbines.

Does this not bear considerable similarities to SMD Hydrovision's TideL device and is there shared IPR? Another concept which would use a traditional tension mooring system, but in tandem rather than mono point would be the tide trawl, which could potentially reduce the installation costs and ease the launch and recovery proceedure. See patent WO03083292 - 2003-10-09. Interesting concept! Does this not bear considerable similarities to SMD Hydrovision’s TideL device and is there shared IPR?

Surely we humans have already done enough to the oceans! Points to ponder: (1) the current (pardon the pun) uncertainty about what is going on with the Gulf Stream, (2) the unavoidable impact on ecosystems (Ben -- a barrier? Think about it!), (3) the wasted energy and resources going into the investigation -- never mind the production -- of such a FORESEEABLE disaster, (4) the built-in obsolescence and maintenance millions this will generate for "Big Power" (oh, think of the contracts!!), (5) the ease with which any damage being done (or costs being created) can be concealed by " Big Power" and the government (Florida, folks) it's gotten to buy into this scheme-- the downside to your having your clear ocean view, Laura. One final point, when we hide the means of production of energy, we allow ourselves the luxury of ignoring its impact. Since we cannot, as a species, trust ourselves to act in the best interests of the planet upon which we depend, we should be designing systems that are absolutely "in our faces", NOT hidden away. Perhaps, then, we would resort to the ultimate (albeit non-"design") solution: drastically reducing consumption of power, and limiting our own numbers.
