Can we exploit Antarctic Ocean wave energy?
« on: 17/05/2012 11:00:44 »
i hear that there is a section of ocean above the Antarctic that the waves never stop, because they have nothing to run in to. is there any way to make a wave powered generater driven by the push of theas waves or by the up and down motion they produce? like an old top, with the spirle rod and knob top? or pull on wires to move turbines, that power large cells used to power new onean liners? Maby use them at high and lowering tides, to charge new age deep ocean towers to signal sunamis?

The Antarctic Ocean is a dangerous ocean for navigation.  However, it is a good point that there are strong circular currents, and waves.  Are the waves also moving in a circular direction in which one could add some kind of a surfing panels to aid with propelling the ship from West to East?

Perhaps with multi-million dollar annual fuel budgets, ship owners will start looking for new (or more classic) methods to propel their ships.

Well, waves don't really stop because they never start :)  Waves go up and down, but wave action does not cause the water to actually travel anywhere.

There are lots of ideas about how to extract work from wave action, but I think they are mainly experimental at the moment. It's not easy to build something that will survive for a long time in harsh marine environments.

Navigation in the Southern Ocean (not the Antarctic Ocean)Is extremely hazardous -- the weather is usually rough, it can get extremely rough, and you are a long long way from any help or civilization. The farther South you go, the faster you can potentially travel, but the greater the risk.

Surfing does not depend on the motion of the water, but on the direction of propagation of waves -- if you ride on the front of a wave, the journey is downhill all the way! But that would only be really useful if the waves were reliably coherent, and I am fairly sure that is not the case in the Southern Ocean.

The main problem with using the Southern Ocean as an energy source for things like an electricity grid is the distance and difficulty associated with transmission.

not for a robot powered sub that could conect to the hull of a ship when called, magneticly. then return to the platform when released, and atach the same way. it dosn't have to exist above water, or worie about ships hitting it on a regular boat rout. if this could be possable would it work?

Here's a great video of a cruise ship in heavy seas.
Hopefully they supplied barf bags to the passengers.

I was thinking one could add an autowinder, like some watches, but one would have to be careful not to destabilize the ship, as if you significantly shifted the center of mass towards the roll, it would make the roll worse, and could potentially destabilize the ship. 

Perhaps one could add deployable outriggers that could absorb some of the force of the rolling.

A sub?
Perhaps it could be deployed to pick up underwater currents, rather than waves.  However, one would have to be concerned with the energy required for deployment, retrieval, and any energy storage or transmission.

true unless the ship was suplied with a counter wheght? maby...

if there was a craft that could handle it in a rougph sea it would have to be raft like. kinda wide flat and bubble like structers like the man of war jellies maby. it would need to be atached like links and be able to handle the cold, and vilolent waves. maby a man of war that could be engionered to handle the cold not be daingrious to man and be large enougph to survive on its oun, and cary equitment, it would recednise as part of it self. i know sifi silly, right? So were glowing mice, fish, and other things people came out with that would sound bad but a living power source, i would where a soler hat to charge an i pod, cell phone, ect.   it would be a long time be for that could be made, and tracked.

I watched a program about renewable energy and one guy have been developing a device that harnesses wave power already. He calls it a 'snake' I dont have the exact details as it was quite a while ago but if you combine it with http://www.sciencedaily.com/releases/2012/07/120711104809.htm [nofollow] a slurry that can store then discharge electricity, you could anchor one of these snakes to a slurry facility and store the energy for later transportation, maybe through pipes

There are three places in the world where Southern Ocean energy could conveniently be exploited. Anywhere else would involve too long a run of pipeline or wiring.

The three places are West coast of Tasmania, West Coast of New Zealand's South Island, and Southern Chile.

But all three of these places are blessed with a very high rainfall, with a very low population density, and with a mountain range running North-South parallel to the coast. These are ideal specifications for reliance on cheap conventional hydro-electric power. I do not know much about Southern Chile, but in the other two places at least, hydroelectric forms a large part of the electricity mains supply, and the electricity is very cheap.

In these places there is therefore almost no incentive for development of experimental power technologies involving wave power, tidal power and/or ocean current power.
