Pressure Harvesting - from ocean depths

Now that's clever. But flawed, If I read correctly.

They have it patented and I have never heard of a patent issued on a flawed design. It's one of the requirements of a patent, it has to be functional.
They do not claim that it replaces other efficient electric generators. The beauty is that it requires very little maintenance and yet can generate instant electricity when needed.

It's not a flawed design. It's just not relevant here. You are misunderstanding the purpose of the device as related to what the OP is asking.

It converts energy between two forms. That's its purpose.
It is not a source of energy. Nor is the ocean.

say what you and the patent office says is true and say that they are in a small way exploiting ambient water pressure. As far as I can tell it is a very expensive form of pumped storage.

Sure it is exploiting ocean depths and is valid to the topic at hand. It is in fact a great thread contribution and has stimulated some ideas and certainly some complaints... lol

Dave, I never mentioned any device in the OP. That is on you.
The OP is merely an invite for people to consider the resources of a deep ocean that is a natural compressor and how that natural compressor can be exploited.

Write4u has posted a system that does in a small way exploit deep ocean pressure... whether it is practicable or economic is irrelevant.

We have already shown that the ocean depths can be exploited by sinking a variable volume vessel on a one way trip. See posts #162 and #165

You cannot generate energy from ocean depth. You can use ocean depth to store energy that you can turn into electricity, but you must put energy into it.

We are not storing energy or electricity, please get that out of your head. We are only generating electricity via a generator which is immediately transferred to the surface network. Nothing is stored. All the potential energy resides in the ocean's pressure trying to fill the empty tanks.

The system harvests electricity from the ocean's pressure. Exactly in context of the OP. You are annoying in trying to misrepresent the article and the method of generating electricity. Read the article, and then give me your considered opinion, please.

I am not the one hijacking the thread, you are with your harping on batteries and storage. There aren't any storage batteries involved, (except perhaps for a standby battery to pump the water from the filled tanks) for use in or on the surface network. All generated electricity is instantly transferred to the surface, when needed. If not needed there is no electricity in the underwater system. There is only ocean water trying to get in, but it can't because the system is closed.

Not even wrong! Only a device that actually stores electricity is a battery.

Well, no. A flywheel stores energy. Pumped storage stores energy. Batteries are just a chemical way to store energy.
The system does not use batteries it uses only ocean pressure to generate electricity, it does not store electricity . The ocean does not store electricity. Ocean pressure has potential to be use as a source for energy.

Nope. Ocean pressure can be used as a means to store energy, by pumping some water out of the bottom of the ocean (which is what this does.)

I have ~160 patents. Not all of them are functional; some are quite theoretical.

Also I would point out that many of those patents are methods of receiving electromagnetic energy over the air. That does not mean that I have patents on a way to harvest free energy out of the air.

It can exploited as an energy storage facility. Just like a bunch of rocks next to a cliff.

You can't extract energy from pressure this way.

dont worry about it... Dave is fixated on his oceans deep pressure can not a source of energy position even though we proved earlier that is definitely can be. #post 162 and post #165

Exactly. It might end up being cheaper than batteries. If so, great! We have another way to store excess wind (or solar) energy.

Oh my, (sighs)
The system does not store energy or electricity. It can only generate for immediate surface use or surface storage. that is simple elegance of the system.

Yes. Which has nothing to do with what the OP was originally asking.

Doesn't work.
You are ignoring the parts where the system requires energy. As much energy in as you get out.
Your idea is flawed.

say we have a variable volume pressure vessel that is cylindrical about 1000 meters long with an inside diameter of about 50 meters.
It's big ok...made of iron and weighs heaps.
It is weighted down with the appropriate weights ( rock or iron who cares hey? Money for this experiment is not a problem...)
It has a hose attached of the necessary length that ports the pressure side of the vessel.
The hose has a tap on it on the surface.

The cylinder is then released and allowed to sink rapidly all the way to 3000 meters trailing the hose above it.
It hits the bottom and has about 35000Kpa of pressurized air inside it. Remember it is a variable volume pressure vessel.

ok any questions at this point?

when we release the hose tap on the surface what do we get in the way of air pressure...?
35000 kPa or nothing?
