JC, it was an excellent video - A++. The concept is my own darling from the previous century. I say it is our solid future for a nearly infinite, completely sustainable energy, in the cleanest, greenest way imaginable. There are so many paths to accomplish it, and you have illustrated the basics. For the skeptics, they only need to look deeper to see the results. One said cold vapor losses upon expansion, but they assumed adiabatic process, yet there are plenty of isothermal processes. Also, there are massive gains once that cold compressed air get’s up to the hot surface with an immediate and massive boost in pressure - the cold compressed air down below is an investment that you recover all your losses from. Again, the engineering side has many path options, all of which are ridiculously simple compared to others. On the eco side, any ruptured line/valve/tank/component/whatever, which all systems have to consider, here result in safe, non-toxic, almost cute environmental effects. A hole in a pipe does not mean toxic oil sludges on the beaches, it means air bubbles which are perfectly safe and actually LIFE SUSTAINING like an aerator in your fish tank. In fact nearby in the Gulf of Mexico (and most gulfs nowadays) there are massive (state/country sized) oxygen depleted zones where there is no life/fish die. You would almost hope for air leaks to restore some life there! Any nick in an electrical wire of other systems, results in an immediate short (deadly) followed by immediate corrosion, and finding the short would be extremely dangerous and troublesome maybe even too for robots (electrified) as you would have to energize to check for voltage over very very long distances looking for a tiny nick in the wire’s insulation… and good luck repairing the internally corroded copper wires… with a waterproof connection… at the bottom of the sea! With air, you’d see the bubbles, all the way to the surface, and know immediately where the pinhole is. No rush to repair, the fish are loving it and it probably SAVED their lives (first that ever happens in our energy vs. nature history). Repairs are as easy as a saddle clamp, or many other methods, and no need to evacuate/purge lines - air and water are 100% compatible, with each other and with all life - plus water was already assumed to be in the mix. I could go on forever, but I just wanted to say - the deeper you look, the more benefits you find. It really is the simplest, leanest, and greenest way to employ our infinite supply of massive wave and tidal energy - way more energy than we will ever need, and even all alone - not accounting for any wind, solar, etc.

Thankyou, yours has been the best best reply yet. I I really appreciate people sharing their opinions. It's not something that I personally could get off the ground or fund. I think people forget that 70% of the planet we live on is ocean. It's a shame not to harness the energy that it carries for the betterment of everyone. We're all too happy to chop every thing down, or dig fossil reminents because it's cheap and an easy path to take.

I always say, “On a planet that’s 70% water, why would you want to use anything else besides pneumatics? Air is 100% compatible with water (vs. ICE, or electric, etc.) My air-powered chainsaw - or air-powered drill, or palm nailer, or yard trimmer, or truck - all work underwater, and the fish love it!! Compatible with water, all life, all nature. All zero-pollution, carbon neutral. And my solar powered compressors, and windmill compressors always keep it that way. With CO2 scrubbers in air filters, all compressors become carbon negative, passively. Don’t get me wrong, I use more electronic circuits than most, but mind you pneumatics are also fully EMP-proof, and lightning/surge/black-out/brown-out proof - EMP/solar flare/CME? Bring it on! Wave energy is the final solution for global supply. Add this to your solution - THE ENTIRE PLANET IS ALREADY PLUMBED FOR PURE PNEUMATICS!! The earth is already ringed with natural gas lines to-and-from, over, under, and through every country, and into every urban and rural city, all the way into even individual apartments. AND ALL THE WAY FROM EVERY MAJOR SEA PORT. So forget about any electric grids, let the sea pump up our tanks forever… just plumb it into the global pipe line grid already right there at the port to send it to the masses.

lglb, given you and I are on the same page with wind and waves (i think) , you might like this idea of using ships as hydrogen factories, taking advantage of the waves - using them to pump air through turbines, the turbines run generators, and in turn create the electricity for electrolysis for hydrogen production. kzread.info/dash/bejne/gJ2ux8Whe8zepco.html

@@jamescraig3007 NO!! But I do love the graphics - again A++ (BTW: what software do you use?) Ok… hold your hydrogen-barge thoughts for a second. 1) I’m pure pneumatics, so skip the ‘convert to electricity’ parts (at least for now), and then I’m all ears. And, do recall that with each conversion is an efficiency loss (wave to air dynamics, air to blade dynamics, blade rotations to magnetic field dynamics, … electricity to electrolysis, … then eventually back to electricity through a fuel cell [most eff.] or burning, etc.) As simple as it may seem, it’s way too complex with eff. losses at each of the many steps, and each conversion phase has tricky dynamics - like balancing ideal delta wave heights to get most usable delta P’s, variable pitching complex turbine blades through bi-directional, non-steady flows, etc. And btw, piston-cylinder sets in place of the turbines would do better with no continuous blade adjustments/costs/dynamics/higher efficiency with no dynamic losses - i.e., just dum and simple. 2) I did this soooo long ago, I’m not even gonna say when, think Reagan:) But the gist is: IT SHOULD BE RIDICULOUSLY SIMPLE. Imaging a similar dock-like structure… with only check valves - your holey boat with just check plates on the deck floor. Just an anchored dock/deck full of cylinder holes and check valves - not really any moving parts only 2 flat plates (checks) per cylinder (hole). The plate checks could be as simple as a plate bolted to the floor - but with long, loose bolts so it can move up and down a bit… I mean they could a basketball loosely in the pipe with a hole in the deck just smaller than the basketball - a thousand really simple ways to make such a check, even DIY for pennies. No pistons, no piston rings, no moving seals, nada, just like you have it coming out of the water just before the turns to turbines. I mean, it’s so simple it’s more confusing just trying to explain it (lol). For example, moving the cylinder instead of the water, just turn a cup upside down and press it into the water - the air trapped above the water gets compressed, you just need a hole in the top (check valve) to let the air into your system (and a reversed check to let the water fall again.) Done! You can pass it through a ‘p-trap’ (gravity filter) downstream to let out any water that came in - extra water no big deal, no harm. That’s it, super simple (no chips/logics/controls, etc.), just massive air. Yes, you can optimize - deck height adjustable for tides, etc. And now you can A) second-stage compress it to match your tank/system pressures - just a big cylinder at low pressure driving a small piston at high pressure (or same cylinders adjustably leveraged for optimal P conversions), or B) Now you can waste all that time/money/parts and add complexity/eff. losses with just a single turbine (or a ‘few’, as they are insanely expensive even before you mentioned “variable-pitch blades”) running at a steady speed. I actually modeled one seaside dock/deck compressor (half an inverted box/garage-without-a-door with the open end facing the waves) and let the lapping “traverse waves” compress in the air under the dock/deck forming its own rolling piston seal (top of the wave along bottom of the deck), and then check valves anywhere/everywhere to port the compressed air in wherever the wave decided was best (checks open as pressures require; always self-regulating, no brains/electronics). Also note that there are numerous alterations to this concept. You could use the reversed check (air return) as a vacuum generator… for whatever, including any air motor running in reverse (inlet is atm, outlet is your vacuum). And/or you could also keep/allow/and improve the amount of water coming in to your system and then you’d have a huge compressed water tank to blow through a hydro-generator (simpler, cheaper than any available air turbine), at will, with lots of water mass forces. I bet you could model any of those systems (dock/deck wave compressors) for visualization in a few hours just by recycling a few snippets of all those fine graphics you’ve already made. Such simplicity really must be seen.

Very smart…it gave me a simpler and more practical idea. Thank You, this was very inspiring!

Great video and neat concept for storage of compressed air. The biggest consideration is the fact that large amounts of the most energy rich components of the compressed air are lost to condensation (latent heat of vapoorization) and wasted heat of compression. At the bottom of the ocean you have very cold temperatures and the compressed air would be cooled to less than 10C. When expanded for use in the turbine, you will have freezing condensing inside of the turbine that will occur. The heat of compression and conversion of atmospheric water vapor with high BTU value in latent heat is converted into sensible heat during compression. Very high temperatures in fact would be generated and lost into the cold water at the storage level.

Thanks Don, great comment! I am sure all engineering issues can be resolved somehow. This was just an idea for a simple (relatively) energy gain and storage using nothing but the waves and air - no complex hydraulics and electrics out at sea to generate electricity. I'm not sure if you have spent much time in the oceans - I personally have spent 650 days out at sea sailing around the globe, and it can be a very challenging environment. When you get lifted several meters by the passing swell in just seconds, you get a good sense of just how much energy is out there. Windfarms seem to take precedence nowadays, but we still need stored energy solutions.

Hey Don, Here's a video for an interesting slow water turbine (vertical axis) concept that you might be interested in. I was really wanting to get a patent on it, with the view that it would be good for tidal energy capture. At the end of the day, its not really my strength, but an interesting concept to an age old design. kzread.info/dash/bejne/eaCGzaSvpbbMgc4.html

Interesting concept. I have to say I would be worried from an engineering standpoint on what happens at each potential point of failure and how easy it would be to do repairs and maintenance. High pressure air at some point has to come out of your tanks and up onto land into that turbine -- a blown seal, a bad valve, a bad piece of piping and that air is going to come blasting out of there with a vengeance. Wouldn't it make more sense to use all those pistons to pump seawater up onto the land? Build a tall tank and the pressure of the water coming out of the bottom drives a standard hydroelectric wheel and turbine with the water going back into the sea (or use the remaining pressure to send the seawater off to a another plant for desalinization). In that way most of your infrastructure (check valves and tanks) is on dry land and the piston pumps and piping will be the only thing requiring maintenance on the water. Heck - if you can find a suitable natural location you might even be able to fill a natural reservoir with sea water and just put a hydroelectric dam on the end with your turbines.

Thanks for your comments, I also see loads of points of failures! but you never know until you have an idea and when you explore an idea. It might not be the best one, but it was really designed to move away from electrical turbines in a marine environment. Nothing but air and water. Maybe you could design the failure redundancy system. Stored energy that is not in the form of electricity is a tricky one, water in dams works well. pumping water up to a height can also be used as stored energy - I am not sure how far or how high it could be pumped with this system.

another benefit of this system is that the decompressing air cools rapidly and can be used to condense water from the atmosphere providing drinking and agricultural water.

Fortunately, things are changing away from petroleum based products, but demand on electricity is about to sky rocket so we need to utilise the cleanest form of energy we can obtain to power all of those things in our lives that we can live with out.

No need for seawater no need for dams or rivers no need for all the old science... we can do my design of hydrowater stations in everywhere also in desert now I have my unique improved design for hydrowater electric stations from One Megawatt to 5000 Megawatts...

a plastic bottle at very low depth will require an EXTREME high pressure pump this requires a very LARGE as well as high tolerances on these pumps to be able send pressure to that depth. -- a non flexible container at ocean floor would require an an insane amount of energy loss to get this power to these types of depths. --- instead of putting these 'tanks' so deep, why not simply place a typical 'electrical generator' run at near or slightly below surface level of the water? -- air i think is an amazing way to transfer force instead of using cables in some type of anchored floating tank that would run a generator ... however since moving large amount of air to spin a turbine, why not use water? it does not compress like air! - using a buoyant float near surface to 'ride' waves, and move a non compressible fluid like water back and forth thru a turbine,, which also could be located at or near -- say 100 meter depth -- pushing water back and forth with the waves -- why would something like this not be more efficient than trying to move air, which has very large losses across the turbine compared vs air (compare water vs steam turbine efficiency) - water flat out nails steam or air no contest ! --- -- i believe this is an amazing idea but some small tweaks i can see these types of systems being used at even ' constant variable' depths to maximize efficiency when storms or calm waters are present. - love the presentation - cant wait to see more, absolutely got the gears going here in my head!

Thanks Roll Bot. The general idea was to keep generators away from the salt water environment, and all electrical connections and cables etc out of the marine environment as well (just air and water only) . The thought was along the lines of creating stored energy, as opposed to trying to harness immediate energy from the wave (there are lots of those on the market). If you create stored electrical energy, you need to mine large amounts of minerals (like lithium) and process them etc - that all contributes to high CO2 output. So just air was a way of keeping everything very simple and low tec.

$ invested / Kwh is going to be funny, also compressing air is one of the most inefficient ways to store energy (20% or so is energy, rest is heat)

Thanks for your comment - I agree with your point. I used to use an air compressor for nail guns and spray painting etc, and yes, at those pressures, the unit used to get very hot. I wonder how that translates when the compression element is floating in a massive heatsink? I wasn't ever trying to achieve the same pressures as used in a steam turbine, only trying to store large amounts of relatively low pressure air, but pressurised enough to spin a turbine.

Unnecessary musical noise just killed the valuable deliberation
