Thanks for looking into it, but those aren't sufficient reasons to not try though. Such defeatist attitude gets in the way of making new tech
That's ok, won’t be easy for many to follow as it needs an interest in the subject as well as a lot of time and the ability to paint a picture with words
No, unfortunately it sounds like a rambling crack pipe dream.
Ten kilos of 💩 in a 5 kilo bag.
A 1000mm Xmax sub takes the prize for "things that won't fit on a small watercraft".
Your word salad paints a picture of a dysfunctional watercraft .
Randy, it really sounds like you are strung out, hope you can reel it back in.
Best wishes,

I’ll start with something fairly thick. Also 0 to 10hz bandwidth ist the target. About 1-2” dia fixed coil with ringed array bar magnets and those in stacks
The vc former will ride on Yamalube and oil seals instead of spider and surround. Stainless steel pole piece. large dome for diaphragm and that can also run on the pole
suspension via spring behind the vc

Spent the day on the beach today with kids. Spent a lot of time figuring out the wave engine and I have developed it sideways a bit to keep a shaft turning
Seassoray
Will need a pair of long stainless steel shafts about the length of the vessel. These would have a bunch of ARBBs spaced out along the length
This shaft pair will sit between the hulls
An arm attached from the ARBB to a decent float. A series of floats along each shaft. Counter rotating the shafts. Longer arms in the middle and shorter and the front and back
End of the shafts geared to gen or thrust
Each passing wave would create a cool stingray wing like effect and keep turning the shaft regardless of where the bows are pointed. Even side on to a wave it will run with the effect and keep turning the shafts
This one is quite easy to test too using the small paddle board. I can make a one piece undulating float fitted along the end of the arms. The shafts will turn slow but with good power
An aluminium frame holding the pair of shafts. Pool noodles bits over all the exposed alloy and shaft bits
Shafts geared to turn a gen and electric transfer to drive motor controller via MPPT charge controller.
In flat conditions, the rider rocking the board will be able to activate the arms. Since they are fitted with ARBBs, gravity will be the restoring force for each arm and water suction will assist that
The arms will hare a large movement, so the only added buoyancy from the floats will be the drag of the gen load
The wording to paint the pic seems coherent enough, as does the means to test the potential to dynamically harvest electricity from wave energy to power a small rec craft with a substantial audio install
Infrasub
To use wave period to gen. Will try such driver motors in the Seassoray arms too
I do believe that there is merit and room for exploration in my idea and a potential to work well. I am unable to be any less rambling than this, and it's up to the aptitude of the reader to make sense of it

Randy, these in fact are sufficient reasons, it is just you do not begin to understand em. Let me unpack these. Being called defeatist is a personal outburst on top of it. I am tempted to stop technical discussion, make everything stop, and ask you what's wrong or how can we help.
Anyway, the physics of things:
1)Mms of such system.
It would be so high, that the power and forces to do that would be exponential. Do you have couple MW of power? How will you cool it down?
2) At 170Hz, you would be breaking sound barrier already, but even if not, the parasitic noises from the cone movement would be as high as SPL produced by the system. If you wanted to play music, using normal midrange and high tone drivers, the experience would be completely ruined by mechanical and wind noises of such subwoofer.
3)Doppler distortion. Listening to something moving 1m would be ruined experience again. It is audible past 5mm already if managed poorly, 50mm is unacceptable most of the time withput cutting the band heavily.
There have been serious tries for extreme displacement lengths for subwoofers. If you want to give it SERIOUS try, aim for Xmax of "3"-4". That's absolutely wicked already, and has small but real chance for success.
With 1m Xmax, you are spending your life on nothing. It might momentarily sound and feel better than what you might be having now, but I've been there too. Don't do that.
My apologies, if you felt the defeatist remark was directed at you. What I meant was that if I took up a defeatist attitude, I won’t be able to look towards making new tech to suit particular use
The build is around the principles of a low frequency audio driver. Something I like to call connecting the neck bone to the hip bone or cross industry solutions. I wish the questions didn't encounter such quick and limited conclusions
Don't know about megawatts, but maybe kilowatts per unit from the heaving seas. Water cooled, self actuated
Crafting side is well in hand with polished stainless tube for former riding casing via oil seals and spring-loaded in a strut type unit and the load from the MPPT controller should create an EM dampener allowing the motor to be used at suspension points
A row of these wearing dome cones on the former end and displacing around 50kg each would be fitted under the deck
Used in reverse for gen. No audio complications. Just a sub with a wave actuated cone and motor reconfigured to make higher voltage for MPPT controller use
I really do not think sub 20hz would be a problem
I really don't see any need for runaway conclusions, since I had mentioned having reservations about wishing to introduce concepts to DIY in a manner it's truly in the public domain and DIYers not being placed at a disadvantage by profiteering. Maybe some respect for the sentiment, if not for the person?
One thing to correct. 1m xmax should really be 1m xlimit
I raised the question to you due to noticing that you maybe able to make some tech contributions. I fail to understand the sentiment in quote and would like to believe that you were not on the same page with intended use. No one is forced to contribute, I use the thread mostly as a silent sounding board anyway as around me there is usually only glazed looks returning to discussing the week's footy

I have a pair of identical starter cords from a pair of blowers from the reuse centre. Can we couple this to a shaft and keep it turning via wave action on a pair of seassor arms firing forward either side of a SUP? The shaft would be geared to the ehub to generate electricity. The ehub arrived today and will be interesting to see the voltage it produces at different RPM. I picked up some rectifier diodes from Jaycar for this experiment
What would be the best battery less interface between ehub gen and the Watersnake? A wind turbine type MPPT charge controller with 3 phase input or a DC-DC converter via the full bridge 3 phase rectifier?
This is for proof of concept purpose

I could stretch the range 50% for extreme conditions, but anything above that is simply unfeasible, unneeded, not worth losing the life on it. I do not know what diameters of speaker you are talking about, but displacing one cubic meter of air will take toll on the enclosure too. That would be some concrete and static engineering on top of that, and no, couple kW is not going to cut it AT ALL. I am standing my ground regarding my opinion.
I did the experiment with 7" drivers and could gen over 2v with the available xlimit on the driver with a simple finger push. If I can DIY a much longer and higher voltage vc around 2" dia riding in a tall stack of ringed arrayed magnets, then I can use up to a meter of available vertical accelerations in the wave to drive that vc up and down the mag stack. If a small inflatable ball can work on a 7" driver to gen 2v with a simple finger push, then what is stopping a 50kg displacement float from running the custom vc to create gen? There is no need for a roll surround and spider. Gravity, water suction and a coil spring behind the vc can provide reset after every wave. An enclosure is not required as the motor will be more like a bass shaker between the deck and float doing regen only. Its housing can be fitted through the deck. Oil seals can provide vc gap
Imagine something like this acting as car suspension dampeners doing regen with every bounce of the vehicle
That wave force was sufficient to crush one of my fibula heads between the gunnel and dock in a tiny boat. I slipped when stepping off
Can we build a generator derived from subwoofers to gen electricity to power the amps for a pair of 12" Polks?

There is a type of subwoofer that uses a stepper type motor to drive a cone with something like a cantilever
For regen, can we wrap a stout bit of cable over the ehub slot and connected via sleeved pushrod and driver by a float in a manner similar to that sub? This sounds like a good chance to give a very large xmax to an EM motor structure
A unit like this can be mounted at suspension points too
For the DIY driver, I'll just start with some 1mm wire and neos from Ali and print a cage to hold them. I have some 30mm stainless tubing to use as the former/piston and can print oil seals in TPU. Yamalube in the vc gap, keeping the shaft lightly greased. Xlimit provided by the back of the float

In a way things are possible, but understand it is above our paygrade. You might be right, being mad scientist, but the ask for us to participate might be too much. 🤭
I think it's just a case of heavy word count and torrential thinking. I grew up reading Frederik Pohl and Ursula Le Guin type of stuff through primary school, I can be excused 🙂 Am not surprised that it's difficult to follow. Especially when the content is mostly thinking out aloud. Please bear in mind that the board is the only place where I there is anyone to raise such thoughts to. Otherwise, not a single soul that I run into in my day who can carry any such exchange
Piling on a battery bank, setting up something like the Watersnake, Torquedo or Epropulsion or an Ali special is easy and been there and done that. Long pro competitive fishing career similar to the American bass tournaments with heavy use of electric propulsion
In the preceding posts, I have laid out specific targets and the ideals behind them. Not going to stop now to design and invent mechanisms to nail those. The details of these mechanics are there in the posts and will continue to evolve until a craft is created that a human straps in and harvests clean energy for propulsion and onboard power
My intuition says to fully explore the 1m xlimit subwoofer angle for the ultimate appendage free results
Think about this, a decent example of such a unit with a bulbous dome cone, set on a bow at waterline would convert wave drag to power for thrust. Waste to energy and there are many other applications in many marine environments
I have a feeling that you might be very surprised by the elegance of the mechanics once it all starts coming together, if not from the ramblings
Don't ever think that I thought little of you and not savvy or without aptitude for the proceedings. I don't think there was an overestimate on my part but an invitation to be a part of it was there
Take it easy man and thanks for taking a look at it anyway
Were I to encounter the mechanisms as described in this thread and configs as written, I would be able to totally follow and draw up a GA. On that note, let's move forward
I spent a lot of time in the water today. Getting a feel of the power in the waves with harvesting in mind. I noticed a behaviour that I can exploit to drop part count even further. One thing I worked out was that I can rely on 2x 70kg of surging force with a movement from around 20cm to up to a metre. Anything more would be considered unlaunchable conditions for the beachcat
Let's consider that the current train of thought was to use a float wheel loaded scissor arm to turn a shaft. This would like a motocross bike with a FAT rear wheel slung between the main hulls and with the bike part being an elliptical
I think we can get rid of the scissor arm, its pivot, suspension and cantilever and not compromise the wheel while retaining wave gen capability
Let's see the config in each area:
1 - Beachcat hulls with the stock x-beams
2 - An elliptical x-trainer driving a paddle wheel in a human/electric hybrid fitted between the hulls. Using ebike systems that support regen and a donor alloy frame from a performance push-bike. So far, pretty sensible as personal water craft
3 - 4x solar panels and MPPT charge controller
4 - Very small biplane rig working mostly as awnings to either side of the canopy. This sail will be loaded like a kite, so no shadows on the solar array
5 - PA system with source and display
6 - 200kg added displacement via central nacelle (A fairing is required in front of a centrally mounted drive on a cat. A nacelle can provide this while adding to the displacement to offset the weight of the drive and sound system)
Guys, a plea to let my know at which point the apparent dysfunctionality appears. I am designing and deploying all the mech system myself. My requests for help are with certain electronic systems like converters and controllers and some upcoming acoustic directivity issues, plus one more below. Art? @weltersys
Wave gen
My original idea was to use seesaw and scissor like devices, but today I hit a realisation that I might not need to run any of these extra parts, as the opening words of point 2 contain the means to harvest wave energy for thrust and gen already. A look at pictures of an elliptical can help decipher my meaning better than a word salad for you educated types. Or just watch the build progress. It will be an interesting exercise to see if anyone else can see what now pops out to this uneducated taxi driver
The generator derived from subwoofers looks to be my quest and is open for collaboration
The seassor system is still number one to harvest from the massive forces available with the larger 6m cat, the Bop

Being an avid reader of sci-fi might pay off big time. I am a SWATH proponent. A few years ago, I designed a vessel as a thought experiment using the SWATH principle, equipped with ram scoops. The concept if realised can open up the far north point of Fraser Island to me. This is 70 kilometres away from my ramp. Big fuel numbers to get there in any decent time. But 3kg coral trout and massive red emperor abound and the vessel, if built, will cover that with a 13B engine in the same time it takes to get there on the charter boat wearing dual 300s
I think I can develop a small generator from that and find enough merit in the idea to try it and develop it commercially. This is right up my ally with experience in building against elements that, with hindsight, can instead be engaged. I have even used the concept in play and agriculture
But Seassor and the new realisation regarding the elliptical and the subwoofer derived concept as public domain DIY. That's four separate ideas for gen that can used together to build one engine to harvest power from the forces present in wave action for direct use or background charging
The elliptical idea thing, while in public domain, will be a quiz to see who gets it first from pics before I spill 😉

If you drew a general arrangement drawing incorporating each iteration described in this thread
the dysfunctionality apparent to us would appear before your very own eyes.
It might, if you included a good plot line with the sci-fi conceptual drawings and were able to find a publisher that would pay you for your thought experiments.
Cheers,
Art
Art, you are being prematurely dismissive of something that you are unable to understand from as described. Considering that, bike to watercraft conversion using light cat hulls is pretty standard fare and already commercialised. The only real deviation is wave gen and PA, so I will have to assume that this apparent dysfunctionality is there due to you not being able to process this
Generator derived from subwoofers. Ok, let's back up here a bit, consider that most subwoofers are on the order of <1% efficient. Some sort of cone, sliding shaft, springs, special lube and seals to make some sort of homebrew generator from the wave action may be on the order of 1% or less efficient, in other words it could turn out to be an expensive waste of time.
To me, this feels like some ramblings, sort of stream of consciousness, without focus. Sure, you can buy things, and assemble them, but if money is tight as you've mentioned, this time and rambling, experimental thought process may be better used on how to generate higher income or more money with less work. Beating the pavement, getting your resume updated and out, upgrading skills is a path forward, not sideways in life. There must be balance in life with work and family, working on endless projects.
My apologies if this seems to be pigeonholing. Solar is about the most promising type of power generation. Solar panels will put out more power if actively cooled, see some of the videos on the Tech Ingredients - YouTube channel. https://www.youtube.com/@TechIngredients
Solar panels also need to be kept clean, and at the correct angle to generate the most amount of power, however it is problematic on a craft of this sort to employ angling panels, simpler to have a flat mount panel, though keeping them clean is important if you want the most output.
Second to that would be human power, as Art mentioned an average human can put out about 100 watts. Elite cyclists can put out more average energy, with short bursts up to over 1kw. Conversion of this energy to power generation will incur losses. Perhaps only about 40-50 watts may be realistic after conversion losses, for the 'average' person. Race bicycles have quite efficient conversion, a figure of 95% was quoted, so quite low losses which isn't going to be the same as driving a generator.
Gear the pedal generator contraption where a human can maintain a cadence of between 60 and 90 RPM. Too low requires more torque input on the pedals, higher forces on your joints. Ergonomics matter, as anyone pedaling may be subject to injury if the pedaling is awkward, tendons and joints can be subject to abnormal stresses not normally found with good geometry. Perhaps you may know a kinesiologist that could help with the geometry of the seat and pedal generator portion.
Good luck.

Thanks for speaking up. I feel that this should not be discounted without a decent try. The expense is in the same class as hobby RC or audio. If such subjects can be a person's tinkering while balancing other life aspects then what is the resistance to expanding similar effort in a different area chasing regen
if it's ok to mess with a sub to hear them, then why is not ok to expand that effort and resources trying to build one that does something a bit different? I really can understand this sentiment on a DIY forum
Again, thanks for speaking up. I have taken a 5-year break to be full-time carer of our baby and use this time to launch a rental fleet of 3 boats. Those are done to survey and with certificates, as well as use permits and such. I have a background in this, but labour help doesn't become available till next Feb for the large aluminium work as the only local person (Sik Boats custom plate welder) who is rated for this work is booked out solid and nothing can be done on those till then. In that time I am working on the office which is the beachcat and some water toys as well as building up a bunch of PA for hire
The budget for this fun side is from my pocket money for tobacco and coffees and totally separate from the work side, for which I have invested significant sums on two brand-new vessels in completed hull form to be fitted out as houseboat and sport fisher. Corona hit and in the aftermath there is a scarcity of skilled labour in our remote costal town. Most of the alloy is already stock piled for the houseboat bride deck as well as all the gear for the sport fisher fit out which I have now changed plans to use as utility and drop the sport fisher angle. I don't want to make any more money from that and have already closed a lucrative tackle manufacturing business
This beachcat was gifted to me for helping a friend hunt down a fault that no one here could find. I have saving around a $100 a week by taking my own coffee and chop chop to kit it out with an ebike system and audio. There is no harm done to anyone, and kids and I might learn a thing or two and keep fit and be outdoors
I could sit in the evening and watch junk while my wife studies alongside, or I could tinker with rolling metre long voice coils and teach my daughter who has been accepted into stem academy how to draw and print a magnet keeper
There in nothing here that hasent already been said, so thats why I cannot fathom the resistance to such tinkering and ponderings. I am already formally qualified in many things, including a bachelor of education k-6, horticulture, VTMS programming, MS Office and self-taught in navel architecture and composites development and what not. Now I am determined to apply all that ability to master what I place my hands on to wavegen which has taken equal placings a thing to do as shrinking massive bass to very small cabs
And has also been brought up as being unreliable for marine use earlier in this thread. There is a roof full of solar for the beachcat so let's look at the marine bit which is causing the problem and see if instead of a pest, we can use that
I believe I brought up the human power first as inclusion of PAS and ebike regen. I bet no can easily make the connection that I have regarding ellipticals as that would require a tech geek to be hands-on familiar with making hard bodies lures work, very personal watercraft design, larger watercraft design, RC, composites, subs, exercise machines, pulley systems and so on. Someone only familiar with some of this will never be able to 'get' the potential to work towards
A good background in this already, as I keep mentioning and hoping that you folks would just accept that there may be some methods to the madness and help the bwoy out with some questions regarding diodes and wires and such. If there are 10 types, I would rather some help from the forum to narrow it down to 3 or so to try. Things like that
Ok, re this point, and it's a good one. I have already addressed this in good detailed mechanisms. At one time in my youth I ran the floor at a large furniture maker wood machines and spray booth section. I walked from this due to a dispute over dreads and was taken up by the distributor for Achilless inflatables and Solomon sports. Trained in repair and maintenance of the Australian Lifesaving Club fleet as well as trained in customising snowboards and bindings and such
I have always had pushbikes and custom things from bikes and such for the water, and regularly use the elliptical machines on the beach. I keep saying that I have the background for having a go in this
I have recognised a wave behaviour that doesn't appear to be utilised. Maybe because, unlike me, no one here has messed with pedalling a submerged frame? We made a hand cranked sea scooter once using an infant's tricycle. Imagine laying on an almost neutral buoyancy model aeroplane and moving that with a hand cranked prop and using the control surfaces for little dives. What I discovered then and yesterday convinces me that I can use human power to direct or control a wave regen process. Human power is a tiny, steady 100w. I think using this 100w into the controls to harness wave power can make for that big gain in efficiency then trying to use that to regen. I don't expect anyone to understand this yet and will be a pictorial quiz starting with the first clue, any online vids and pics of ellipticals
Coming back to this point. This much I know, with subs there is back EMF just like an ehub
There are elements that make it a better driver than a generator. I will examine what this is and can this be reversed, resized and repurposed. I don't do things like watch TV, so what's the harm with a roll of copper and a bunch of magnets from Ali?
Are we still doing DIY stuff?
Will try to keep this less rambly
We will test the subwoofer type gen after successfully creating a motor that can gen a usable voltage and power. Let's see what it takes to gen 10w per unit and how much it costs to build that. An array of 10 costing under AUD $1000 seems like a good target to aspire too and can merrily bounce away under the deck or in suspension parts
Essentially turning the subwoofer into a high power mic, driven by wave force. Physically, it would be a very closed system with a minimum of moving parts and not much in the way of wear. Cost per unit can be effective too. The power is there in the ocean, can we make a good harvester?
Why is it wrong to try?
The elliptical idea? This needs to be at human scale to work and will be part of the beachcat build. Will fit a prototype of my sci-fi idea as a mounted regen engine as well
Also making a water toy to develop another single unit that features most of the DIY ideas that I have raised so far as a mounted regen engine, The targets will be strong onboard bass and gen to power that and a slow cruise with only tiny battery (can't work or play without dub). Does anybody want to be a part of this attempt? A complete open source compact water bike thingy that draws running power from the surroundings? I am confident about the CAD and craft of it but get snagged on the electronics
I picture a row of 'subs' fitted under a bridge deck, trapping a gym ball between the water surface. Each passing wave will activate the subs and as will any on board movement. Efficiency is a by product of creating a subwoofer to fulfil small enclosure duties and such and that there is an opportunity to redesign the motor structure to be a better gen when freed of audio duties
