I bet a dis-masted sailboat with a small cabin and a centerboard keel would be PERFECT for your next boat project. Displacement hull, WAY more freeboard for mounting solar panels, a cabin to sleep in and get away from the sun and waves...I think sailboats are a legit use-case for solar propulsion, so it would probably interest sailing nerds too.
Oh, absolutely. That’d be sick. I have been thinking about doing exactly that, just not with a dismasted sailboat because I love sailing. But most sailboats that aren’t tiny have a motor anyway, and having that be electric would be sick. But it’d be pretty expensive - boats aren’t cheap and all the electronics and motors and stuff probably aren’t either.
Only issue would be sourcing an electric motor large / powerful enough for such a large boat (in comparison)
Keep the mast and have solar sails. Solar panels that you can raise up and rotate to catch rays and wind
And that you'd likely be using higher voltages and requiring HV cables and electronics. I'm not sure how much equipment would carry over to that project.
So much work and you could just use sails 😂
What totally blows my mind is, that we're at a point where you can PRINT large parts of a solar dinky, live on it for days, have it auto-pilot really well, have a video editing station on board, and being able to make fly-by and overhead footage ALL BY YOURSELF, and all this time be reasonably comfy. And it's completely sun-driven to boot. Just crazy.
this is some cover of popular mechanics in the 1920s typa shit
@@resmartedI know exactly what you mean
And at the same time, there are people who flatly deny science, just as climate change, evolution, etc. Without science, we would still live in caves.
Right!! Extremely impressive!!!
Well said. And on the other hand, people die by fentanyl abuse, shoot and bomb on each other in Gaza and a lot of other sad stuff. I love the world we are living in but here in Germany we have real problems with the growing gap between rich and poor. This will lead for sure for a huge crisis is the next 10 years.
32:00 Woah, that's a KC-135! It's an air-to-air refueling tanker (you can see the boom arm and pod right below the tail when it passes over). It's probably part of the 92nd Air Refueling Wing out of Fairchild AFB since they have air-refueling training as part of the 509th.
I literally watched that plane on Radar for a while, so I saw that one
I was looking in the comments too see what it was. Thank you sir
I’m 19 and going to school for aerospace engineering and you truly are one of my biggest inspirations, thank you for quenching our thirst for these great engineering UA-camrs. Hall of fame for sure!
Become a solar panel technician. Much less school, decent pay
The solar panel frame seems a little delicate. Maybe you could wrap a pool noodle around it? If it catches a wave, it should have ample buouyancy to glide over the top, preventing 'scooping damage'.
I agree, if he increased the Iyy it would make it less suspectable to damage from bending in the y axis as well.
I'd think allowing the panels to make a canopy for him would probably be a bit better, allow for them to not touch the water and then he does not need to use the chair designed with an attached canopy
@@mrpants8976It'd be too top heavy
@@mrpants8976I agree, a lightweight aluminium frame would be ideal 👍
@@FaeTheo Yeah a setup like that kind of necessitates a Katamaran. For enough stability i mean.
36:00 was the coolest shot of the whole video. Please do more astronomical time laps clips in your camping vids. It's just so cool to see the rotation of the earth via the movement of the stars.
With the music in the background it felt a lot like dying in outer wilds.
YOUR WRONG! it clearly the stars that moves around us, "SO STOP" spointing Nonsenes!!!..
@@veldrovive9442 that looks like a cool game. I just added it to my steam wishlist
@@TheEndOfNether ??????????????????????????
@@zavtparticles6828probably just some flat earther or something, ignore em
Maybe try a catamaran hull on the next build? You could then have small displacement, make a big roof of solar, and have somewhere to build a cabin. I love this series. Thanks!
I definitely thing a more efficient hull would add some serious range, and you've still got the columbia river trip you didn't finish this time :-)
Exactly why I suggested a trimaran hull, he was bounced around pretty bad in the wake and waves. Some decent shade for the batteries would help as well.
I feel like a trimaran is the ideal design for a solar boat. You've got large flat space between the outer pontoons and the center hull, and the pontoons keep the solar panels supported properly. The narrow hulls allow the boat to move through the water with little resistance, and they keep the boat super stable.
Create a low cover for the front of the boat that would keep your electronics out of the sun without blocking the solar panels yet allow wind to pass underneath. This would greatly help with overheating. Maybe even one for the back as well. Use light aluminum frame with cloth streched to keep rigidity. Leave the middle areas open for seating and such.
He would probably get away with painting the electronics box white and adding a small fan. Or since he has water cooling already, just add it to the electronics too, but that is probably unnecessary complexity for little benefit if a fan would work.
use the panels AS cover
But they have a very deep keel
I wonder how difficult it would be to automate the speed based on the fullness of the batteries: eg, once the batteries are fully, increase speed to match what the solar panels are providing, and then decrease speed as the sun starts to go down. And theoretically, you could have a servo drop anchor when the batteries drop to a set point so you could go to sleep and let the boat just keep cruising until the batteries go down. Probably not a good idea for safety but it's a neat idea.
really easy, you could even make this "analog"
No. It is not a good idea. It's never a good idea to let anything make the decisions for travel on water, ground, or in the air. Short of space travel, you want your decisions to be deliberate with a man in the loop. It would also be a useless addition. The energy you would route to the motors would be better served charging batteries. Speed is less a necessity than stamina. Also, a cloud or shadow would halt the motor and then it would spin up with full sun. This would cause more wear and tear to the working parts from constant declaration and acceleration as opposed to a steady speed.
The only issue is efficiency. Motor current increases faster than boat speed. This is fine if all of your energy is "excess", but the efficiency is better is low speeds. Also, the power generation follows a curve.
I expect that the most efficient approach is somewhat different. You want maximum charging to take place during maximum solar collection, because that energy can then power you overnight while running as a lower and more efficient speed. Basically, the most efficient approach will have the batteries drained down to almost zero right at the start of the day, just as there is enough sun to completely power the motors.
Basically, for every day you want your total generation (in this case, idealized total generation for his 1000W system in Seattle in July is probably around 4.5kW) to equal your total consumption. If he runs for 16h/day, and loses 0.5kW to inefficiency, then that gives 250W for motors during running conditions.
@@mattmarzulathe boat already drives 90% of the time on autopilot. It's already controlling the throttle to keep speed constant. Ramping the throttle up and down to keep charging the batteries due to variable solar power isn't a huge jump.
In terms of hull efficiency you may want to consider a small catamaran, say 16-20 foot, and put a rigid roof on it to mount the solar panels and keep you and the gizmos cool. Further propulsion efficiencies might be gained from putting a printed duct/cowl around your props and using a prop form optimized for that.
Exactly what I would suggest and planned to build, I have a Pacific Cat 19, very efficient. I would also suggesting he build a rim-driven prop, which is what I wanted to do. I was hoping he would do at least one boat chanty song like his other video on a solar powered kayak.
This is one of the most satisfying and relaxing videos of the year, thanks for sharing your trip :) The fact that your boat has an autopilot makes it even more satisfying to watch! Maybe for the next trip you could add a solar roof, so you have more protection from rain and sun. You could also lift up the side solar panels to roof level, so they don't hit the water and can be used as side walls in heavy rain
And by raising the CG you make the boat unstable. Keep a low CG. I'm a 60 year designer and builder of boats and light aircraft. Dandahermit
Could have tilted the panels to form an a frame shelter. Dandahermit
@@dandahermitseals5582 That's an important point, didn't think of that. But i'm not sure if the destabilisation is so much worse than being exposed to sunlight and rain. The used panels are flexible and lightweight, maybe it would be possible to compensate the weight with weights on bottom?
You’re an amazing person, Daniel! So glad you did this! 👍🏼 Thanks for taking us along…
This film was like a short holiday, love all your engineering projects and the nature around your place. Greetings from Germany 😊
The flat ribbon of water is due to a subtle current. Currents are strange on dam-bounded lakes where you wouldn't expect. The old river channel is deeper, and that's just one thing that can cause subtle currents to do strange things. So, the wind is blowing just hard enough to kick up small waves, everywhere except where the current is already moving at that speed. OR, opposite, sometimes the wind blows the the other way, lightly, and it only scrapes up waves where the current is against it. I used to fish for bottom feeding catfish and knowing where the old channel was, helped locate them sometimes.
Thanks for that. I've always been curious about it too, but never knew how to properly search for it. Cheers.
they call it a "rip" in my country.. on an ocean beach, it is the warning sign of a dangerous undercurrent, and will pull you down under, and out to sea
"Just gotta make sure you don't hit anything, but other than that you just hang out" lmfao hell yea
If you had a roof system to protect yourself from the elements you could add another 3-4 solar panels and have unlimited energy even if you go faster. Just sayin…
That would destabilize his small boat way too much
Yeah I think he would need a keel to offset the top weight
Even just a little hoop of shelter with or without a small panel would do wonders for comfort and protecting the laptop.
These solo expidtions with prototypes are wild and I'm absolutely here for it. Like the risk factor for results is so high, you're trusting (pun intended) your life with PLA layers
he had a paddle so if it broke he would be able to paddle to land
You never go out on the water on a powered craft without a set of paddles. Its common sense, one of the things i see people respect the most to be honest. I dont think i have ever been on a craft that didn't already have backup paddles somewhere on the craft.
No life risk, he's got cell coverage a paddle and a week of food and water.
But he does lay it all on the line! And it's great.
@@nathanz7205 I go out without them all the time. As do most boaters, I would wager. Thats because paddles are useless in anything much larger than this boat, So if you ever been in a boat thats above 20; 24 foot at the most, ask the people that own it to paddle it. They cant, to any meaningful degree. Certainly not if there is any current or wind in the opposite direction.
@@GoldenCroc naw, I've moved a 1.5 ton boat with a kayak paddle. it starts slow, but compared to having no navigation at all, it can be a boat saver.
I really enjoyed this. There are not a lot of 39 minute UA-cam videos I'd watch for the whole time but this was just so peaceful.
This is awesome! Been living on board for 7 yrs now, I could only wish to do this kind of exploring on my diesel powered river boat! Hope to see more soon!
i have to ask, have you considerd using pontoons for the solar panels to sit on instead of floating, you could also possibly add an extra panel on either side with the additional wight allowence since you wont be using those hinges/brackets. the pontoons would have to be able to fold inside otherwise it would be way to big. I freaking love your videos, they keep me so inspired for my own 3d printing and solar projects.
It would probably make it harder for him to fold them up and down for storage
@@tobyrichards6004 Pool noodles are rather light
Dude there's so many good ideas on here.I was thinking about some kind of solar sail combo? Is that a thing?
Dude drove a boat with 3D printed parts like propeller... it's impressive
Ikr this is my first video of his and i gitta subscribe. Very smart kid love to see this from this young generation. Gives me hope for the future
hey daniel, watched your journey last night and just had to say "nice job sir"! i loved every second of it. been a fan of yours for years, and this one nailed it! keep it up and thanks.
In case you were wondering, the "missile silo" is actually a "beehive burner", a building used for burning excess sawdust from old lumber mills
at 12:53 , that's a wigwam burner (also called a teepee burner, or beehive burner) they're used to control the burning of excess sawdust produced by sawmills
For the nautically inclined the reported speeds were between 3.9 and 4.25 knots with the regular props and 3.1 knots for the toroidals. A fast sea kayak likely could keep up, though probably not all day.
this was such an epic video..thank you so much for bringing us along. I'm really curious to see how your future experiments with the toroidal props do. keep at it
Super compelling video, Daniel. I really enjoyed this format. Thank you for creating such cool content!
"Because how many vehicles are there out there where you can just turn it on, start going, and then just chill, you know?"
Trains!!!
Such a relaxed mood :)
Suuuuuuuuuper coooool! Man, from what I could tell, you thought of EVERYTHING, from clothing to food to spare parts, and I'm sure WAY MORE than that! What a GREAT adventure! I'm sure it was pretty stressful and boring for YOU, but for we who are watching, it was AWESOME! Keep up the *GREAT* work! Cheers!
Pretty amazing journey in your solar boat!! Keep up the good work.
Dude in the years I have watched your videos this is definitely one of my favorite! I would love to see you expand more on this idea!
Fun video! Whilst I don't think there's much to be gotten out of toroidal props, I think your power absorption issue is related to the arrangement of your blades. I would suggest having another go with your design improvements but using angularly displaced blade pairs to reduce pressure/interference drag, and reducing that 9 degrees on the joining wall as that is acting like a large paddle.
I can't wait to see this on Trending 😎😎 Great progress and I'm proud of all the contingencies and redundancy you've prepared for the trip. This is an awesome series! Cheers 🍻
The dedication of this man never ceases to amaze me
What a great video. Great for you for having the will to do all of this, I cant imagine or underestimate your effort
Wow ! what a trip . . . thanks for taking us along . . . Your engineering skills and sense of adventure will take you far . . . Thanks, Bob
Thank you for taking us along on your epic mission! I had so much fun!
I love this project! I know others have already offered suggestions on the panel rigidity, so this might have been suggested and I just missed it. Consider using something like 1 inch square aluminum tubing for the solar panel frame. 3D print some corner brackets to allow for simple assembly, and you could still maintain your lightweight solar wings, while having the added rigidity and support that boxed tubing provides.
What a fantastic trip. Thanks for taking us with you.
This is the video I've been waiting for, love the boat adventures. Keep it up!
You gotta remake this thing with a roof that holds the solar panels. Doubles up as shade so all your electronics don't overheat from the sun 👍🏼
I love when you run into people who are curious about your project. They're always so nice!
that was a pretty cool adventure, thanks for taking us along. mike
I wonder how this would work if you upscaled the setup? Take a pontoon boat for instance. You could have solar panels covering the roof and then have side panels that fold up. Not sure that would provide enough power to run something like that. It would be an interesting experiment though.
Also a severe increase in expenses...
@@sloth6765 True. Does not mean it won't be cool to see something like that. :D
@@sloth6765I’ve owned pontoon boats cheaper than just one of his 3D printers. Shoot for the price of his CNC you can get a pretty good pontoon. And he just needs the frame which is extremely cheap
@@gagegr I suspect the boat would be a tiny portion of the project. It'd need bigger motors, bigger panels, beefier ESCs, bigger batteries...
Pontoons are stable, but they tend to be pretty drag heavy. Some of them come with ready made "walls" and roof which could mount solar panels. You could do a decent clip with enough panels and large enough engines and large enough battery. The battery weight would probably be the killer. If you don't mind not pulling a water-skier the whole time, you can set up something that mostly runs on panels and save some battery weight.
Love your content. So informative and calming. And your camerawork/video editing skills have gotten almost as impressive as your engineering!
The harmonic, almost symbiotic relationship of your inner love of both tech and nature on full display. I dig it. Thanks for the inspiring video.
You did really great man! Part of boating , you will find, is becoming acquainted with that feeling of being remote and entirely depending on yourself far from anywhere!
He has some of the chilliest videos on UA-cam
Loved every minute of this, it'll be interesting to see what upgrades you make for the next trip, but will definitely stay tuned to see that. Happy sailing!
Extremely impressive sir!! So much tech you incorporated to make your excursion an efficient and beneficial factor of making a great video, sharing it with the viewers. From the 3D printing explanation of the boat parts and gear to editing your videos. The bravery of camping by yourself in various remote areas throughout the night is impressive also!! Well done sir. Well done indeed!!
An environment friendly traveling excursion. No carbon emissions
@@kakletv8119 that's a bonus.
Always keep a hand paddle. A small cabin boat with solar would be great for a long trip, that way if it rains you're not outside in it. You could get an older swing-keel or similar weekender sailboat, pull the mast off, and make solar panels for the sides. Could even have a close friend you can stand being around that much go with you. Living the dream!
You make such great content dude, thank you for all the effort you put into this stuff and helping others learn and inspiring them to do cool projects. Really appreciate it
Wow what a trip. I've loved watching the progression from concept to idea to test to adventure.
I put this on as I was going to bed and found the whole thing very relaxing. The whole area is so different to where I live and a unique perspective which seems a bit surreal. The vibration from the blades is similar to that experienced with pusher prop aircraft and wind turbines but in reverse. There is an area in the swept area where of the blade where the oncoming fluid is a different speed or otherwise disturbed. What you did was to try and smooth that out and yes it will only make a difference at the back. This is because the fluid stays laminar when you are squeezing (high pressure) it at the front but when its returning to fill the void (low pressure) it likes to get chaotic. This is fairly intuitive way to think of it. The toroidal props are a bit of a minefield. They are effectively 6 bladed prop with extra drag at the tip, they will never be more efficient because the rear blade is running in the wake of the front blade and the front blade is affected by the rear blade which changes its effective AOA. I wouldn't try to work it out. The less blades the better, you can even have 1 blade and a counterweight. You only need more blades if you struggle to absorb the power at a sensible RPM. 3 seems to be the happy point. I wonder how much better the solar works when tracking the sun?
Really enjoying your boat adventures. I'd love to do something like that! Nice area you live at, too! Love all the cliffs and trees and beaches, it looks wild and largely untouched.
Greetings out of my small 1 room apartment in a big city in Germany 😅
This concept is amazing.
Making the boat a little more comfortable will hopefully encourage you to take longer journeys. ❤❤
It's fun to watch too...
Can't wait to see what you use for a displacement hull. I have a Hobie 17T Kayak, but I think a small sailboat would be a better choice for your application.
Great video,,I appreciate your in depth tech talk explaining what you are doing and what is going on with the equipment that you are testing,,very informative,,thank you.
Awesome project, with concise intelligent commentary. Thanks and go you.
Love this boat series. Pls keep going and take another trip :D
Yes it's very likely only the rear part of your shaft-casing. There was likely a large periodic separation bubble before that caused the vibrations. Making the rear end come together over a larger distance (think truck vs sedan) decreases the chance for separation and thereby periodic flow patterns.
It should also increase efficiency a bit. Although the motor shaft probably doesn't contribute too much to the overall drag.
I love the production value that your drone adds.. amazing!
Loved this video! A small sports sailing catamaran (sans mast) might be the most efficient for power/speed. Steering could be achieved by differential engine power rather than dealing with the additional complexity of a rudder system. And more space for solar panels and maybe a small tent as well. Good luck with your iterations!
We definitely need to see more videos like this 👍
But I would make your boat more into a "house boat" and keep testing new prop designs to develop the most efficient prop. Plus maybe adding a small wind generator might not create too much drag to make it worth it?
Doubtful, Those wind generators dont do all that much unless they are quite big or its REALLY windy. Neither of which would suit this boat.
It'd be far more efficient to just use a (wing)sail, Newton's Third makes wind turbines on vehicles a huge pain.
This is the first video I've seen from your channel and this was super fascinating! I'd totally enjoy this kind of project! I did wonder if you'd considered making a roof assembly for the panels so you could have shade while also keeping the panels from getting caught in the waves.
you're in for a treat catching up on his other videos
Too top-heavy prob
29:23 the air
A rear solar panel might help reduce overall drag. Note a lot of old wooden ships have quite a lot of raised deck behind the submerged hull.
Import the shape of your prefered propeller and convert it's shape to toroidal.
I love this content so much. Thank you for all the work editing this must have been.
Great video! When starting into more longterm-missions probably time to look into collision avoidance options of ardupilot. I‘d bet that most of the boats and bujis do not show up on maps and also don‘t habe any ais transponders. Probably also see if you can integrate your depth-measurements so you don‘t run on ground…
More of these adventures!
Brilliant work mate, living for 72 hours in such a small boat is an epic mission in itself but building all of the power systems yourself is next level. A trailer sailer without the rig would be perfect for your next missions, as some of them have swing or lifting centre boards/keels and are displacement or semi displacement hulls.
Keep up the great work
Great video! Regarding the toroidal props:
The Sharrow propellers are laid out for ICEs operting in the 2-3000 rpm range for 150+ Horses and god knows what kind of torque ranges.
Since you are using electric motors to turn your props, you have a nearly constant, but narrower torque range. You may need to design some sort of planetary gearbox to drive the toroidal props at higher speeds, OR, modify the layout, for lower RPMs and higher AOA in this case with a step-down gearbox.
I was thinking that the solution to the solar panels getting bashed might be simply mounting them higher, which could also afford some shade from the sun in the boat. However, I'd be concerned about them catching wind (i.e. trying to become wings) the higher they get off the water. I'm wondering if it would be possible to take a cue from the ground effect stuff you've done and add some "wings" to which you'd mount the solar arrays, which could also be used to support outriggers (fiberglass & foam construction would make sense) - that combined with a decent canoe hull might result in a more efficient hull design. Don't know, not an expert, just a thought.
Hello, I noticed that you and your buddy Petersripol have been doing a lot of boat + solar stuff lately. Do you guys often bounce off ideas or is it just a coincidence of common interest? I know you are both UA-cam's premiere experts in RC vehicles, so it would make sense if you guys like doing similar things around the same time. It is more fun to talk to a peer than with yourself after all.
Automated early morning sailing while strapped into a sleeping bag.
That must be so insanely pleasant and comfortable.
Take all you have learned and build a full fledged RV boat!
I love Keller Ferry campground. We've ben camping up there for 6-7 decades. Water ski all day then play some volleyball and eventually card games in the evening. You can see the northern lights from the campground if you're lucky. My all time favorite place to be. Fighter jets would fly below the top of the canyon walls. The were told to stop because when they went supersonic windows would break. Now they fly higher and slower. You could see the pilots faces. Thanks for sharing another rad vid man.
You should do the math for your speed and RPM range to find the optimal pitch angle for your props - my suspicion is that it's way, way finer (ie, smaller bite) than anything you've been using. Compare the boat speed to an e-foil's speed, reducing pitch proportionally should get you in the ballpark.
PS the freeze dried chicken coconut curry will blow your mind
I would love to see more of this series
I really enjoyed that, dude. Thank you for showing us the beauty of the pacific northwest and sharing all the nerdy ins and outs of your boat, its very cool! I also liked the electricity math for the dam, mindblowing what humans can achieve isn't it?
I thought this was going to be click-bait, but I was really wrong! It was a well filmed documentary of your trip and a great review of the problems you faced. Very entertaining. You have a well informed group of commentators here as well.
Very cool trip!. Interesting that your boat uses almost 5X more power at 2m/sec. (4.5mph) as my ebike does at 12m/sec. (25mph) It would be interesting to see how efficient other hull designs would be.
Boats are comically inefficient compared to land/wheel based stuff. Our boat with a 420 horsepower LS3 barely does 50 mph.

Smart idea. We enjoyed the trip with you... Thanks
I’m not even into electronics or doohickies but this channel always amazes me ….awesome bro
Another question, if build a roof for your small boat, with fold up panels and panels in the center, would that make it too top heavy? If not, that would keep the panels well out of the water and provide shade. At night, folding the side panels down would provide some shelter from weather. :D
same idea for me with the whole roof being solar with the two folding panels he has hinged to the bottom and can act as a wall on the sunny side, but then its probably impossible to tow at speed without tons of reinforcement
This has been a really cool project to follow along with. I would be interested to see more solar powered watercraft projects in the future! Maybe a pontoon boat with a big solar panel roof.
I wanna see some diy version of the 3m$ catamarans with like 50kW of panels :D
Hey Daniel, thanks man for taking us along!
👍💪✌
Hey, I got in early for once. Love your videos man. Keep up the good work
What would happen if you do two attachments for balance like a trimaran? It will be safer and the waves will not be able to tip you over.
I loved this video.
Thank you for your work.
love this video! The nature of my work doesn't give me much headroom to travel around much, so I really enjoy your camping trips :)
Question, guys. Now, putting a magnifying glass on solar panels. Will this improve their performance on days when the sun is not bright or if there are some clouds? Will it make their performance better or are they limited to a specific production?
The magnifying glass would need to be larger than the solar panels to actually catch more light. Although the glass itself might also block some of the light
What if the solar panel lit lights pointed at the solar panels?

I'm glad to see you're starting to take your personal sun exposure a bit more seriously (the neck/face covering, etc). As someone who has already gone through skin cancer I'd been a bit horrified at some of your previous all-day trips - sun lotion can only do so much. In a previous vid you mentioned that you'd discounted a roof style array but that would really help surely? Anyway, stay safe and don't forget to consider yourself when you are optimising your designs.
I feel totally inspired by this channel. I especially love these "adventure" videos using the "homemade" tech
Fun to watch! That's a lot of power those solar panels are generating. I cannot do this in our waters as they are too busy sadly, but would be a cool project.
Enjoyed this, I'm guessing in your next design you make a lightweight collapsible roof to hold the panels up high and provide cover, a roof that covers the entire boat plus extendable wings will provide even more power.
This was amazing. I showed my wife & we just planned a trip there. If you go bigger with your boat you should should out Phil Bolger’s flat bottom sharpies. They are wicked efficient and some have cabins (like the Idaho)
We get 10mpg at 15kts. Only 1500lbs.
your videos are always chill. Keep up the good work
Cool to see you exploring places nearby. Honestly gives me inspiration to go do some more solo exploration.
