so there must be a layer which can separate the gas from the sea water right? then if you able to penetrate the layer with your pipe the gas surely will go up for himself. But i still don't understand how a gas can be trapped on ocean floor..

Microwave heating is very different with combustion because microwave don't cause fire. But, if you talking about the video i attached above i think because of the distance between the water molecules in air is too far, its got no chance to bump into each other to generate heat.

I like to share this link here, this just an example but usually this Pourbaix diagram was commonly used to control corrosion. Except cathode, anode, electrolyte and oxygen, Electrode potential and pH also play a vital role to determine corrosion. Corrosion DoctorBut in my opinion, its should be enough to use sodium chloride to make your bolts rust. And perhaps you should lower the pH a little to accelerates the process. but, too low on pH might cause a development of protective patina thus prevent further rust. So should be careful.

I'm little bit confused on stage 3 & 5, how a stream of RF can turn the gas into plasma? I understand the concept of generating plasma using electrodes, but for such this VASIMR engine, what happen to the atom of the gas when flowing through those RF antennas? With the same principle, is it can be true that a human body can instantly exploded in RF oven?

Are you really sure the methane is in the gas form? because I only heard about solid hydrate of methane buried under the ocean bed.

yep, methane hydrate only formed under high pressure + low temperature.. not only on ocean floor, it could also formed under frozen lake. So be careful when you smoking while walking on those frozen lake ^^,. Usually they used to store those burning ice in liquid nitrogen to preserve its form. But i really don't understand how methane hydrate cause the airships disappear at Bermuda triangle??

For comparison, can you simply explain to me what is the correlation between wave frequency and the behavior of the plasma. Why they use RF generator instead of microwave to produce plasma in rocket thruster? also, what we need if we want to produce plasma from something not gas, may be from water or solid matter perhaps?

Did you ever heard about methane hydrate? Methane hydrate Due to rapid global warming, scientists were afraid that enormous amount of methane will be released into atmosphere and contribute to more rapid heating. Several O&G companies like Conoco Phillips are currently found some big reservoir of methane hydrate in Alaska but i don't sure if they already can take the methane out or not. Last year i read an article that they had a problem if too much methane are taking out because it will cause the base of the reservoir become unstable. So they plan to inject a same volume of CO2 to replace the volume of methane. If the plan succeed, we can reduce our global warming in big percentage

I think vinegar just too weak to make the nuts&bolts corrode. I ever use a mix of vinegar and sodium chloride to simulated corrosion by acid rain at marine atmosphere and my sample got no corrosion product because that vinegar just dissolve it and wash it away.. so no rust, only corroded surface.

Thanks for the great link CP! and yes i think i couldn't agree more with you two, weather & climate isn't something we could calculated with math isn't it? It's differ from astronomy where we can put math in it. I wonder why climate & weather doesn't have computable patterns...

ok, that's clear enough for me to understand the basic. But i still don't understand why a gas become visible when got ionized? how they emit light? where the photon comes from?

Can you imagine this, a clear water puddle with a silt deposited at the bottom. When i stirred the puddle gently, the mud below rising up and form various turbulence shape and also some small tornadoes. So i'm wondering if the same thing happen in our atmosphere where the water represent the air while the mud represent clouds. If it same, can we use computational fluid dynamics to calculated the behavior of the cloud especially for tornadoes and hurricanes??

urm.. so fire is a kind of plasma but plasma definitely is not a fire??. About ionized gas, how much energy needed to ionized a gas for example... an argon? what types of energy sources we need to produce plasma? last but not least, what is the minimum temperature does a plasma have? I can't find any below 10^2 Kelvin. Can someone give me an example?

urm.. so you agree plasma is a fire?? then, should the temperature in that glass increased?

Is that really plasma?

I have a friend who study Quantum physics and he had told me something about the teleportation of information. I don't remember very clearly but if i'm not mistaken, he said about a photon was being shot by a photon and it will produce or give birth to a new photon. The newborn photon will have similar characteristic to its primary and there are entanglement between both of them. As the primary receive an information, the new photon will also instantly receive the same information and vice versa. So can this possibly be used to teleport a mass?

Using low-boiling point liquid such as ammonia, methanol or propanol should increase the efficiency as less heat required to convert it into steam. But it may only practical if the design is a "closed system" because those liquid can easily evaporated and pressure control also must be took into account.

I could felt the same thing, the machine is just way too simple but very efficient. So i decide to convince my team to find another sources instead just being obsessed with the undersea pressure. Ocean wave should be a potential sources as it already contains the energy and we just need to find out how to transform it into desired energy. Thanks for your great advices!

Yes, sorry for the misconception. As you said before, "in order to use a force to do work (to make energy), it must cover a certain distance" From above we finally get : Work (in) = W (out). So to do this work, we must have an equal energy. Take potential energy; PE = mgh = Fh when h= d PE = Fd = Work

Yes, i will save a lot of time if i just do as you suggest. But the Wave Roller is one of the existing devices which extracting wave power to move the turbine. Here i list some of the method which exist today to generate force from ocean power. You can search those in google for more info. 1. Salter duck (Wave) 2. Sea snake (Wave) 3. Ocean thermal energy conversion (temperature different) 4. Wave Dragon "tapchan" (Wave+gravity) 5. Wave roller (Wave) 6. Oceanlinx's oscillating water column (Compressible fluid + wave) 7. Sea Gen (under research) - Wave farm (wind farm like) So our lecturer need a new kind of method which still do not exist, although this coursework just contribute 50% from our total mark, our dean is looking forward to it. If we can design a new method, he want to apply a grant for further research. At current state, me and my group decide to use the extreme pressure of ocean's floor as the main energy contributor.

Typing "renewable+sources" on Google may not quite find what you're looking for. At least you should already know what types of renewable powers which exist today and you just search deeper for it. However, using website as a main source of information is not smart for a PhD student i think.

Is it correct if i said it is more like when you " waving" your blanket or a carpet. the blanket or the carpet won't get stretched which means no particle displacement in horizontal axis but only vertically.
