No Sailing, Just BULLSH!T - Sailing Uma [Step 273]

[@paulkelly2882]

Episode’s when you talk about technical issues is always great, you have the voice for it bru

[@NigelMarston]

I love UMA projects. The way you go about things - using as much of a commercial product as possible and then adapting it - is exactly how I go about my own projects. It's really great that you're ahead of the game with this sort of thing. Hopefully someone in the right industry will come along and work with you to develop something.

[@klardotsh]

Love the nod to Erik, and definitely love that idea of using the torsion rope as a turbine shaft, that's crafty!

[@ErikOrdway1984]

My name is also Erik and that freaked me out as I was not really paying attention at the end and the Dan said my name and pointed at me.

[@BrunoVasco]

I'd imagine if some kind of flexible carbon tube long enough would be better (and possible in terms of cost) for energy transfer (because it should be stiffer against torsion)

[@chickenfishhybrid44]

@@BrunoVasco definitely, it would just be about storing it and dealing with it if they really do intend to make it removable especially. I was thinking potentially some type of telescoping aluminium pole. Something similar to a paint roller extension. Could also make something out of small tube and use some type of pins or couplers to put it together for use.

[@00708046]

With the torsion line you could mount more blade(s). You can use a boost transformer to raise a constant voltage to a usable voltage going into your mppt controller . The initial generated power needs to be regulated somehow like a car alternator has a regulator to prevent over voltage.

[@mfritch]

Dan, another thing that might have even more torsional rigidity and would stay straighter would be to use some high burst test hydraulic hose for your shaft. You might even be able to put the hose inside a PVC sleeve to make it even stiffer. Schedule 80 PVC electrical conduit has a pretty thick wall. If you got really sharp you could put seals at both ends of the shaft and then put a light oil in it to cut the friction. You should be able to find some hose about the size of the bore in your coupler. If not, you could use a piece of shafting installed in the coupler and then slide the hose over it. The rubber liner of the hose could be drilled out to get a very tight fit on the stub shaft. A good hydraulic fab shop should be able to use a crimp on fitting to attach the hose to the piece of shafting. You could then do something similar at the top. You might even be able to put more tension in the hose connector to keep it from whipping against the mast. I look forward to seeing what you come up with. Is there gearing in the turbine to spool up the RPM inside? In Sweden where I just bought a farm, have also found good quality crimp on studs that will cure your problem with the screw on terminal blocks. The smoke may have simply been the new boards burning off manufacturing residue.

Greetings from home (Canada). I've been enjoying your posts from day one and have to comment, yours is by far the most original, interesting and truly adventurous. 99.9% of every other sailing channels are showing and doing the exact same thing sail warm water only stay away from the rest of the planet. I didn't think it was possible but I'm sick of seeing the Caribbean, Mediterranean and Florida. But you have shown us a picture of Norway its waters and the North Atlantic no one else has. Illustrating that not all sailing is fair weather but it can actually be raining or snowing and using the sails is your first choice over motoring. Thanks for showing us a truly different part of the planet. You were leaders in all electric propulsion and again are leading with vertical wind generation, well done Uma.

[@akjhome]

@sailinguma we are an electric sailboat in the PNW. We tried a big wind generator mounted on our mizzen mast first. It required a lot of wind to generate any usable electric over too long a period. And besides the issues you wisely mentioned, the drag was affecting our sailing, balance and steering. And those are moving parts requiring maintenance. We switched to solar only. No hydro. We haven’t plugged in since beginning of season.

[@DKHvideo]

Lovely project! If you add a universal joint at the generator input, it will not be as sensitive to alignment between generator axis and the torsion line. In the scene 03:48 you have made a yoke coupling out of a tube, the slot is at 90° to the first bolt hole, try leaving that bolt, through the generator shaft, slack so that the coupling can rock a few degrees and that should do as a mock up. I agree with the comments about a thrust bearing, the tension on the torque line was possibly causing the generator bearings to bind, hence the squeak and slow running. The generator's bearings will probably designed for rotation only, with no provision for thrust. l love taking things and adapting them to suit a new purpose, good luck... hopefully you will create the Uma class generator, which we will soon see on every clever yacht.

[@Weazle099]

24:05 (The trapped air in the sand) The out going and incoming tide is the cause, as water drains out air will fill between the sand and because of the (water service tension rule) trap the air when the tide "floods" the shore line again. What also helps a lot is that there is no or very very little wave action to smash the air out...

[@VmaxBR549]

Just a few things to consider for the wind generator. The unit you have is way to big for what you are using for a wind rotor. Look at most pull behind aqua gens and you notice they use a small diameter generator section. That is because they cannot create a huge amount of torque to spin the gen . With a wind gen you have even less torque so the gen has to be small. You have to trade off torque for RPM. With a smaller gen it can rotate in less wind. With the torque line mount all you need is a straight coupler that mounts onto the gen shaft. Then you swivel the gen where it mounts to the deck to line up with the torque line. Also you want a gen that is at least 3 phase to even out the pulses from the gen spinning. No wind gen is going to delivery huge amounts of power at one time. But it does give power 24/7 as long as the wind is blowing. Just a thought, TP

[@TM-529]

8:54 for a good reason, they are very inefficient. When wind blows through a normal "vertical" propeller, it hits all the blades at once and ALL blades transfer that force to spin it in the SAME direction. On a "vertical" propeller the wind pushes on all blades as well, BUT having a center axis means one blade wants to go in the one direction and the other two in the opposite. Yes they present a different shape when at the "wrong" side but still generate a lot of drag and Is this drag that reduces the efficiency up to 30% or more. If you need smaller and more powerful wind turbines, pick one with more blades and less diameter.

[@richardgreen7225]

What about the Darius design? I would expect the blades to be generating lift 90% of the time. It also looks like a design that you could put on a mizzen mast, let spin when you are not sailing, and lock perpendicular to the boom when you are using the mizzen sail.

[@tim1398]

Never put soldered stranded wire into a screw-down terminal - the solder slowly flows under the pressure and you will end up with a bad connection in time. It's against electrical codes because of that. You can crimp the stranded wire into a ferrule, and put that into a screw terminal.

[@yankeepirate8927]

As a Union Electrician&live aboard for 25 years, told by an Arctic Sailor NOTHING you do stops corrosion; not shrinktube, liquid tape, solder, whatever, I prefer thick solid wire in a bent loop, but I'll take STRANDED, split&twist fibers, form them around a nail or post, twist the end again forming a tight loop, and crush between stainless washers for a "LUG TIGHT" connection that lasts, knowing in 2-5 years I'll probably have to redo it. As for aluminum connectors and soldered or crimp sockets I hate them; they all rot.

To smooth delivery of a "choppy" power source, you may need to implement some kind of flywheel between the torsion line and the motor. With the moving gear, you may want to enclose it in a housing. Good luck!

[@kiritosao2661]

Some suggestions.... 1) Increase the length of each blade from 24" to 48" tall. 2) Decrease the curvature of the blades by using a larger diameter of PVC pipe. (These two changes mean the overall blade diameter would be smaller and could increase rotational speed) 3) Hard shaft a ten foot 6 - 8mm rod on a Universal Joint at each end with the top mounted to a sealed bearing. 4) Top bearing would be mounted to a hinged plate attached to the mast. The hinge allows for varying tension from a backstay. In theory this would allow the unit to remain in place in a permanent sealed and covered mount. Just a thought, Kirito in Providence

[@G11713]

I like this from the title, actually. It did not disappoint, as usual. There seems to be no reason to *not* have a series of those vertical axis blade sections linked and hoisted by a single jib halyard, like a sail, pinned to a generator on deck (or below) able to fully capture that torque. I am sure blades could be fashioned to compensate for the tilt if it's an issue. I wonder how easy it is to trim and curve some plastic sheet into blades and clamp them to that torsion rope... Nice.

[@ian-c.01]

I did a fair bit of work with wind generators at one time and I came to the conclusion there is no substitute for size. Small ones make more noise than power and although they seem ideal for sailing boats they really are just a novelty item that produce a token amount of charge. That 'motor' as you call it is the alternator, it needs to be spinning more than 1000 RPM to get a reasonable amount of power and as you know the wind is never constant. It also probably will not stand up to a lot of tension being put on the shaft, pulling on it like that will wear out the bearings very quickly. Also they need some type of brake fitted to stop them over revving in high winds, there are mechanical solutions and electrical. You can have a small paddle that is spring loaded which will operate a small hub brake or cable operated disc brake. Or you can set up an over volt detection system that returns power to the alternator which energises the field coils and pushes against the rotation to prevent it getting out of control. Both systems have their faults but you cannot run a wind generator safely without one. Large wind turbines are much more efficient because they have a lot of inertia and can be geared up to produce higher RPM's which produces higher voltage and higher power, small ones are only any good for lower voltages, less than 24V and low power.

I adore this forward thinking. Electric sailing, no diesel, no pollution. I was wondering a few months ago how you could use wind on a sail boat to generate more power. I love what you came up with honestly. Brilliant. I had been thinking myself, how a Catamaran could use water between the hulls , to create more additional power while sailing. Using the same concept in rivers and stream with a small two foot water, paddle generator. Using the same concept, a small water paddle placed under the boat could create more power while sailing/moving through moving seas as you sail. There are more ideas out there as to how to generate enough power to live with, on a high level. I'm pretty sure you two will be leading this forward thinking technologies for future sailors and even bigger boats, ships, etc... Kika, Dan...Thank you.

Spectacular photography! Good to see that the wood stove is in use. Great creativity and teamwork. You may already have these ideas in your wind vane "options" list: #1. Use a metal/plastic tube/pipe rather than the flexible torsion line. In concept, this would be similar to the threaded drill pipe used for water/oil drilling. Use 1/2" or 3/8" tube, 4' in length threaded at each end. Easy to assemble and store. #2. The wind vane appears to be about 2' high and 3' in diameter. Consider stacking several wind vane segments to increase the torque.

I use screw terminals with stranded all the time, but you HAVE to crimp on a ferrule.

[@andreassittig2772]

Absolutely. DON'T solder the wire ends you intend to connect to the screw terminals. Solder is too soft and the connection will become mechanically loose and electrically unreliable over time. Yes, many people have done the soldering + screwing in the past but it's bad practise.

No wind turbine or one too noisy - put up with it no.. invent one! Just wondering though - could you put more than one of those wind turbines above each other to improve the sail area - potentially generate more power in lower winds and shorten the tension wire (great idea by the way!). Have to mention the techical side of this video and the editing - I always love your videos, but this was great - starting with a beautiful sunny drone shot of Uma looking as if she was in the tropics before panning to show Norway, brining it all back to a caribean/norway barbaque at the end was brilliant, although poor Kika's feet!

[@trailsandsails2722]

Love your connection to NBSJS. You guys and Erik are fantastic. Some ideas about wind charging: 1) Not sure why you went with a 3 phase gen but you need to be sure your MTTP or whatever controller you have takes 3 phase input since that needs to be converted to DC. 2) you need a firm connection to the gen. How about meter long thin wall tube/pipe tied together with couplers? 3) there's probably a threshold RPM for output on the gen and that;s usually somewhere roughly around 1000rpm. You need a reduction gear or at min a large wheel attached to the windmill shaft with perhaps a fan belt to the small wheel on the gen. 4) knowing the generator's need for rpm and wattage output, look for calcs. on the mechanical energy input needed. One way to see if all this works is to find the mechanical energy conversion based on wind speed for that wind mill. Let me know if you;re interested in that. Best wishes!! Dean

[@christophermelo7889]

First, I love that you guys try stuff and don't get dissuaded by the nay sayers. Keep at it. I completely agree that wind and solar are symbiotic energy harvest methods. As far as the turbine goes, the reason vertical axis suffers in efficiency is that it has to drag a vane against the wind for every vane the wind pushes. So each rotation looses some % potential net energy capture. Since the total energy gained over time is an integral of the energy per revolution and the rotation speed, the small efficiency loss is magnified. Anyway, I totally get the mounting challenges of combined wind and solar. No easy answers to hard questions.

About Your issue in @13:15 with a screw terminal. Actually they are much better things what You're advertising them ;) First at all DO NOT solder wires tips, especially DO NOT use lead free solder to do so. Lead-tin solder alloy is very soft, so You won't be able to screw the terminal firmly enough. The more torque You are apply the more soldered tip will squeeze, so finally the connection may get very loose and starts to burn due to increased resistance. The proper way if You have stranded copper wire You should use special steel ferrules (like Conrad Electronic part number 490812ks) which are pressed onto the wire tip using special tool. Then such can be firmly screwed using such terminal like it would be solid copper wire. Instead of screw terminals You can always use WAGO connectors and terminals. WAGO produces spring terminals which as name suggests has a spring pressing against the metal contact and keeps contact good even in mobile/vibration environment. You don't need (and really shoudln't) solder wire tips then. Look at WAGO CLASSIC series (example part numer: classic 222-415)

Just a thought about the squeaky motor. The motor probably doesn't have the necessary bearings to deal with the linear tension of the torsion line.

[@donaldmaywald8937]

Exactly, need to install a load bearing plate with coupling above the generator to take the load off the generator bearing.

The squeak was from the fitting I made. Also, most sealed bearing can handle a small thrust load, if they’re installed properly. But that motor isn’t going to be staying long.

Great idea, may need to concider the loads you are now excerting on the parts, I think the pulsing and resulting sqeaking came from the torsion line union, install a universal joint at top and bottom of torsion line terminal connections to effeciently deal with the off axis alignment. If you can design this to take the linear loads and buffer any rotational axis misalignment then you can make you motor mount more modular and effecient. Interested to see how this poject develops, many fundamental challenges to overcome, hoisting/lowering, balancing speed wobbles, magic smoke ...... might be worth looking into and power input controler like a Scotty from Safiery. Good luck guys, love your work. FYI - I use 'bootlace' ferrules for the screw terminal blocks (changing them out for soldered connections is better for permenent installs)

Dan ”the man” saílorised a vertical windturbine ❤️❤️👍🏼

[@kwik2hear915]

He still is"The Man"!!!!!!!!

[@aeroearth]

You've got my Design Engineer brain working! Most horizontal wind turbines I see on boats have three narrow blades. Could try increasing the number of blades to 6, 8 or even 12. Could also try increasing the blade area too. For the vertical axis generator could try doubling the height of the blades or link modules together. Single tri blade unit for windy days, double for medium wind strength and triple for light wind days. Could also be a unit that has the blades sliding inside each other which could then be automatically pulled in or out depending on wind strength and also controlled automatically to match blade area with wind strength. The AC generator could be mounted under the deck with the input shaft under a flush mounting hinged, edge sealed small hatch. Would need to rotary seal the shaft but a lot easier to do that than seal the whole generator and its electrical connections. Dan, you are right about those screw terminal blocks. However I have come across a 'work around" where the strands were first crimped in a tubular brass crimp which was then clamped in the block. Second downfall of that terminal block design is that there is no provision for strain relief of the cable. Acceptable for a building application but when something can move or vibrate you really need strain relief on all cable connections. Take care and have fun!

Couple of ideas for you to think about. 1- What about getting e-bikes to get around when you are on shore for exploring and grocery "getting". They an be disassembled for transport in Coco. They have small trailers available to carry larger loads. They can be re-charged over night via the batteries. Light weight and no need to hiring cars or taxis. 2- Look into get a couple of electric pole saws. These devises have a battery pack with a 10 foot extension powering a small chain saw. If you use just the pole extension (linked together) you would have 20 + feet of a transmission rod to power the motor from the wind turbine. It would already have the necessary shaft linkage and connectors inserted into the poles. You mentioned that you wanted to start with an off the shelf idea and modify it. Again a couple of ideas for you to think about.

How ironic, the most relevant topic you have ever covered to date. My passion for sailing is all about self sustainable green living. This is the kind of thing that got me to follow you two. Love it !!! Keep it up !!!

The BS wasn't BS at all! Resourcefulness along the way.

[@frogwraps]

First of all let me say you guys are amazing my wife and I have been watching you since you started we're an older couple and bought a 38 ft Ericsson sailboat unfortunately we don't have the drive that you youngsters do but everything that you have done to your boat is simply amazing. Also everything that you've done to your boat is exactly what I had intended on doing to mine I have a wind vane ready to install just like yours I want to do electric motors just like yours I want to do battery Banks just like yours and I've been studying wind turbines and thought about doing twin vawts on the back at the radar Tower one of the things that I thought about and making a vawt was to do counter rotating blades so that slower wind speeds would create twice the energy instead of just one stator you would have two going in opposite directions because the blades would be going in opposite directions counter rotating squirrel cages so to speak just a thought.

[@walterhunter4011]

I love your experiment’s in wind and solar power. I can watch these type of videos for ever as I love technology with a bit romance 🥰.

[@remielowik]

Arent you putting a vertical load on the bearings of the generator/alternator? My guess would be that putting tension on the axle that way will wreck those bearings in no time.

[@nealeburgess6756]

It is nice that you have bought a pretty windmill to decorate Uma. Maybe you should paint it bright colours. Then it will look even better. It would be even better if it made electricity. They all said you couldn't make a viable electric motor system for Uma, but you did. Good luck with the wind generator. I have a feeling that at some time in the not too distant future Uma will have a new viable power source.

[@erlixerlix7573]

Interresting idea! The axial load on the generator will probably kill the bearings though. It was not designed for that.

[@SailingUma]

That generator isn’t staying long. Like we said, it will all be swapped out as it evolves.

[@ericsaul9306]

@@SailingUma it shouldn't be that hard to have the same system and avoid placing so much axial load on the bearings, you could have a bracket soldered to the motor chasis for tension and a rigid thin "core" to transfer the rotation, something as light as possible like a pvc pipe, so that the whole system can be disassembled when storms happen but it's easy enough to mount again the next day

[@gregm2074]

I think this is a really great alternative idea. I may go with a more rigid carbon fiber tube as the "drive shaft" eliminating rope flex and tension. It could be stowed below just like a long fishing pole. Looking forward to more experiments from Uma 👌👍

[@andrewjacoby4475]

Dan if you are on a boat the go-to connectors are crimp. (At least according to Florida scuttlebutt) Soldering gets corroded and the wire next to the solder becomes brittle. Nowadays they have little sleeves called ferrules. Everybody loves them. Stranded wire behaves fine in the "nightmare" connectors with the screws if you have the ferrules. Take care.

[@BlueMooseTraveler]

Great video guys!!! ♡♡ Suprisex you haven't hooked up an alternator to that fireplace fan! Haha!!

[@martsmith2412]

Great video as always :) Love the NBJS Reference and message from EA! Vertical wind turbines... You are creating a brake and wear point by pulling on the spindle like that, consider a solid bar so there is no tension between the vanes and generator. That way you can focus on steadying the vanes top and bottom

Couple suggestions. You need a thrust bearing to take the tension load (bearings in the motor/gen are not made for high axial loads) and also adding a universal joint between the torsion rope terminal and the driven shaft will help with some of that "clocking" you were seeing due to axial mis alignment. My biggest concern with the hoisted turbine is how to lower it when its fully spun up. Maybe having a "bucket" style lid that can be lowered over the turbine to effectively shield it from the wind while hoisting and lowering that is only raised up after its at full height. Interesting project.

[@brianmiller7934]

Have you run into Erik? Quite the character!

[@nikhoward]

Awesome vid as always. I know I’m a couple of months behind (catching up after lots of travel in last few months) and not sure if others have mentioned but you can use “boot lace” crimps with terminal blocks if using with stranded flex not solid core. But I love how you build, test, improvise, adapt - great skills. Really must get back to Norway one day. Thanks as always. Nik, electrical engineer, Cornwall, UK.

[@loefstrand]

You need a thrust bearing at the "torsion wire connection" to not kill the bearings in the generator.

[@Estereos]

... and some kind of mechanical transmission to speed up the generator.

[@jamestheotherone742]

@@Estereos I doubt the rotor has enough torque to spin up the generator with a gearbox.

[@josephclayton1835]

I agree , you need more tension because allot of energy is going into moving the wind vanes laterally, but your generator bearings may not handle that much thrust

[@guygillmore2970]

This has got real potential but I second that observation. The bearings will be able to take a bit of thrust but nothing like the load you have put on. A broom handle connection would keep it all in line without high tension, but then of course you will need a bearing higher up to keep the blades from moving laterally.

[@caveguru]

or, if you did design/source a transmission shaft in place of the rope then the bearings could be dispensed with. I'm thinking of a giant version of a speedometer cable- a large (~3/8" OD?) metal spring steel rod in a sheath that controls it's shape instead of needing to use tension on the rope. Would be heavier than the rope version but perhaps more efficient depending on what can be accomplished with the bearings.

[@glennedwards1449]

Having a garbage truck of memories I can remember something that should be of assistance. About 6 month to a year ago I was surfing YT about hydroponics and came across this guy who was heavily into designing his own systems. He designed his own Wind generator like yours except fixed with a solid connection. The thing is he went from a prototype to something that produced approx 300 watts roughly 10 to 20 times his initial output. This was not by making it by making it bigger but his generator was a round horizontal disk rather like a plate and like plates he was able to stack the Stator's slightly offset on top of each other. Wish I could remember the video it was a brilliantly simple engineering solution and very compact, though of course this term is relative when you live on a 30 odd foot sail boat

[@tomwilliams8675]

You need a steel or fiberglass rod to make the connection between the motor and blades. You're losing too much torque in the rope. But I'm sure you knew that and were using what you had on board 😉🙃 Looking forward to this build Dan. I know it's going to be epic. 👍👍👍👍👍👍👍👍👍

[@drchill8837]

Really interesting. I've also been kicking around the idea of making a vertical wind gen, and your idea of hoisting the vanes and keeping the mass down low is a stroke of genius. BUT, I don't think your torsion rope is ever going to work well. I'm pretty sure that the strands inside are continually twisting against each other changing the axial loads across and along the rope, continually lengthening and shortening it, and causing internal friction that's hurting your efficiency. Look into the problems of using wire rope as a flexible drive shaft. And wire is much more rigid, obviously, than sta-set. It will also beat the crap out of the bearings in the alternator. I'll bet you a buck that you will get much better results using an aluminum tube, even though it may need to be shorter to be practical to store. Keep at it. I'll be curious to see how this progresses. Knowing you guys, it will ultimately be highly effective and utterly beautiful.

[@alyssastokes9296]

I actually choked when your video popped up on my phone and I read the title. Funny.

[@sandoula]

Hi Guys! Me and my husband we own a Jeanneau 36.2 of 1996 and this year we have mounted a vertical wind generator, it is not a marine one and many parts of it had to be changed in order to become good enough for sea conditions. Until today we are happy with it, trully not so efficient as the horizontal one, but it actually works and looks a bit weird on the boat, but its always a good way to start discussions in a new marina which we love it :D

[@e_ederer]

Was gonna watch anyway, but the Erik Aanderaa reference put the hook in!

[@thehealthynutt5705]

This is my absolute favorite channel/show/video to watch. I've seen every episode and to me it's better than watching any tv 📺 show. Dan can do anything. Kika always has the same can-do attitude. Best entertainment and stunning visuals I've ever seen. Sometimes I wish Sailing Uma was a tv 📺 show but then I think it would lose it's freshness and authenticity. Thanks for making this channel as well produced as any network, and IMHO it's the best.

[@barefootdriver5152]

Loved the sneaky intro. Stunning cinema photography.

[@coylewho]

Dan. Kika, you are inspirations. I've been thinking about this for the past month or so. You're engineers. I'm a machinist. I think it has to be mounted on the lower shroud. Efficiency, ya know? I see the short turbines you have presented. I know the goal is to make them the whole length of something. I mean the whole length of the mast supports. Joints will have to be machined to allow rigidity for the mast while allowing the shrouds to spin. Right? The generator will have to be mounted below deck. Is there room? And the generator will need to be balanced to the top joint and the bottom joint which I foresee to be stationary bearings, so more cables or other fasteners will come into play. I know my ideas expressed here are crude. I was just so pleased to see your video that witnessed you guys trying to solve an issue I've been thinking about for so long. I wish you the very best. Please let me know if I can be of help solving this issue.

[@abatesnz]

Four weeks ago I suggested you get look at sort of hinge apparatus for your solar panels to avoid overnight snow accumulation and to be closer to perpendicular to the low rising sun angles you get (if at all) that far north, then reproached myself a few hours ago today for not making allowance for the need to have a sturdy fitting for the panels to resist really strong winds. EDIT: Oh, you can hoist them vertical @18:00 - just not hinge them fore and aft! Not to be daunted by, or learn my lesson from, such an experience ... would you consider some sort of dismantlable apparatus that you would put up (once anchored/moored) behind the boat, above the self-steering wind vane (which also has a dismantlable aspect, I suppose) and hold a horizontal-axis wind turbine? It wouldn't block the solar panels if dismantled, and would only be erected on windy cloudy days (when solar isn't generating). That location would get it away from your cabin so that the noise doesn't affect your sleep. That far from the end of your boat might give the vibrations a seesaw/leverage effect, and you wouldn't want it in place when using the wind vane or running down wind in big seas, or going stern-to on certain town quays in the Med. It might also affect your LOA and fees for marina or town quay berths or taxes, depending on whether it was up and included when measured. And dismantled, it might take up some space, but maybe you could work out how to re-use the spinnaker pole (in conjunction with the solar panel frames) to mount it, so the only extra volume needed is the turbine itself.

[@abatesnz]

Ah, I see you are using the spinnaker pole with the torsion line and now know you have a torsion line for furling your a-sail. I didn't know that yesterday when I said you were very brave flying the kite without the main up to dowse it behind. So I will reproach myself about that too. ;-) Another thing occurred to me. Get a Torqueedo, figure out how to mount it upside down on the end of the spinnaker pole and in a way that it can re-orient itself to catch the wind with increased blades attached. Then next week: how to generate electricity from a Torqueedo as you drag it through the water... ;-) Then the following week, build your own regenerating Torqueedo by mounting your generator like this guy did: kzbin.info/www/bejne/Y4XXoYConcSciJY

[@abatesnz]

Could you fix the house wire lego connectors with aluminium foil or tin foil, or bits of cut up hair clips? PS No sailing, just bullshit? I love your technical videos - the CapeHorn install, the copper-epoxy, the first elec-motor install, the swap-out for the ocean drive. I can go sailing any time (if we weren't locked down) - but I can't just see this tech upgrade/innovation movies anywhere.

[@geirmyrvagnes8718]

I would have considered a universal joint and a thrust bearing when connecting the torsion line to the motor/generator for smooth rotation. Love the BS.

[@LeonardoZangrando]

Great experiments! I'm also a fan of the vertical axis turbine (no pun intended!) and I designed a super lightweight rotor made of aluminium tubes and sail cloth. Regardless, I see a potential efficiency loss in your arrangement when the turbine axis is not fixed but wobbling around like at 9:29. I guess that the final layout should have some system to keep the axis parallel to the mast, possibly 2 supports/bearings. It very much depends on what parts you will want to leave in place: the full rotor and supports, just the supports, or nothing as I guess Dan is thinking of. Looking forward to the next iterations!

[@aprilsteel9466]

Bolt connection points into the deck would seem to be needed . Flush and sealed so nothing to trip on.

[@johndeverteuil136]

Love your DIY videos as I am refitting my own Catamaran. I am also entertaining wind turbines and have found them less productive than solar when you compare cost. My solar is massive, 1600w of panels, with 1600AH of lithium. I agree that having redundant system that augment each other is essential. I have a few comments. 1- Everything I have read is that vertical,which i like, produces power at a wider range of wind speed. Are you finding this as well?? 2- Replace your torsion line with a Standing rigging cable this will not have any twist from a line. 3- I hypothesize that the torsion line will also decrease efficiency compared to mounting directly to the motor. I realize that you need clean air for the turbine, but I am assuming that the loss of energy would compensate due to a direct drive mount. 4- I will mount mine wind turbine with a cork base to decrease vibrations, these mounts are also used to decrease generator and motor vibration noice. My prayers go out to the people of Haiti, I hope your family is safe.

[@soloflight75]

Love you guys!!! I am sure at some point the aluminum-graphene batteries will hit sailing. I can't wait to see what genius ideas you come up with using that technology. Also with the advances in solar collection when might you be ready for an upgrade to the panels you currently have?
