Deep Ocean Power Generation ?...... JAPAN's Gambit !!

[MJCronin]

It's not TIDAL POWER, this methodology harvests kinetic energy from deep ocean currents !!!!

There are specific benefits for Japan and the ocean curents near Japan are more suitable

Sounds interesting ... some prototype facilities must be built and tested first

Never forget that the Ocean is corrosive and eats everything !!!!

I don't want to hijack someone else's thread, but when I read this post my immediate thought was along the lines of, "How innovative and interesting an idea! We might find that there are no "GLOBAL" solutions, but rather great local solutions. Like how Iceland is basically 100% green because of the abundance of geothermal energy".

Then that got me wondering whether geothermal is a big thing in Hawaii. I don't think it is, but I have difficulty understanding why. It seems like such a slam dunk with all the volcanic activity. Anyone know why Hawaii is so far behind Iceland in this regard?

what are the deep ocean currents, that are better sources of power than tidal flows ?

I'd've thought that there may be more mileage in utilising the deep ocean temperature and pressure

another day in paradise, or is paradise one day closer ?

Considering all the hot Fukushima water they want to dump, this could turn out to be the world's first hybrid ocean current/nuclear energy source. Bonus!

so a 330 ton prototype can generate 100 kW.

they're going to up-scale to a 2MW system (20x bigger)
and then hope to get 200GW out ... from 100,000 of these bigger units !??

I think an alternative power source has to be coupled with a huge reduction in the use of power. It appears right now that they are only looking at one part of the problem, and not very well at that. Everything is deferred for decades.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Do you feel any better?

Agree with that, if you don't use it then you don't have to generate it. No-one else is concerned though.

Some good reference papers on Deep Ocean Technology ....

The sad part is that no one seems to acting on it, or at least not quickly.

For what it's worth, I did look up some stuff about geo thermal power in Hawaii.

Apparently, the Big Island already has one. It produces about 30% of the overall power for that Island.... 38 MW which is pretty substantial with an 8MW expansion underway.

However, one of the article I read said that this plant was based on old technologies and they'd like to add another one that would produce more power.

In addition, there are plans (though I don't now how actionable they are) to add a similar plant (the more efficient variety) on Maui.


Honestly, if the Federal government were really interested in reducing CO2 emissions as fast as possible, it's these type of "slam dunk" projects that should get more funding over roof top solar panels subsidies whose primary purpose is to make the politicians look like they're doing something and to allow certain rich people to "virtue signal" to all their neighbors.

harnessing deep current energy is better than tidal energy because the deep current are consistent. There is no need for the extra cost of saving the energy.

A lot depends on the attitude of the people, too.

I think it depends more on the abundance (and scarcity) of resources. In Iceland petroleum products are imported and very expensive, geothermal plentiful and relatively cheap.

Add to that Iceland is a small country

The problem with sloppy work is that the supply FAR EXCEEDS the demand

 

Deep ocean currents, tidal energy, geothermal ... what was the question again?
