Circumnavigation of the earth when?

You might want to do an IR camera crack check on those panels now. They're *able* to flex but not intended to flex while in operation and the cells themselves will still get damaged. A lightweight yet rigid mounting substrate would be advised, or at minimum a support grid underneath.

Winch was probably pulling the spud up out of the water, the huge metal spike that goes into the river bed to hold the barge in place while the crane works.

Catamaran or Trimaran would definitely be the ideal hull configuration and give you maximum style points too.

you can also flip the motors around and have them in a pull configuration. they also do this on large ships with azipods so the prop can take in clean water.

Nice video! Some bio-corrections (based on taking marine science like 40 years ago): The "sea slug" was actually a sea cucumber. And the anenome-like things are tube worms.

For your solar panels, I feel like you're either going to drop a main pin or a cotter pin into the water eventually. I think a "ratchet" system might have been better for controlling the position of the panels. Using pins looks tedious and it's an accident just waiting to happen.

surprised how practical this is, making the Tech Ingredients catamaran combined with solid sunpower rigid panels for a roof would make a hell of a boat!

Might help you to add buoyancy to the "wings" like outriggers, or a tri-hull catamaran.

Version 2 will have a solar roof, with solar outrigger/wings that fold up for easy access, and fold down to protect the cabin area from rain.

Definitely, a roof build would be awesome. Utilizing the sun at the same time being protected from the sun. 👍

I love how curious Daniel is about everything going on around him. What all the ships are probably doing, how much they cost, how they got there, who owns them, how they operate etc. he reminds me a lot of myself that’s why I enjoy watching his videos. Also a great teacher. Explains difficult things in a simple way. Don’t ever stop making these videos !!!

For this setup and maybe in the feature V2 version, there are two-sided solar panels, so with the water reflection or the roof reflection you could give a good amount of energy with even 1 panel ( Same size of one set that u have in the side). Additionally for the roof would be interesting to have a system that elevates the left or right side depending on the sun's attack angle

You're really good at keeping our attention. Very entertaining.

I absolutely love the dialogue and description narration of what you were seeing and where it was with details. Feels like you were hanging out with you both, makes for great content to listen and watch.

man i like it how you take us all out with you for a ride on the boat, explaining and showing us around like a dad lol

I love all of the cinematic shots with the drone and bridge I would really want to see more of that

The roof is sooooooo much better of an idea. Shade on the open lake is pretty important, especially for something that goes slow and will be cruising for hours. They also get in the way and are easy to damage when docking. They are also a paint to adjust. Also some panels loose all power if even a small area is shaded. It would be cool to do a solar house boat. My dad had an old Boston Whaler built in the 70s. It had a nice outboard motor and a driver spot in the middle on the right side. Having the flat bottom made it easy to beech.

I recently saw a huge cruise ship with propellers that pull instead of push and they said it's done for efficiency, makes sense to me. Might be something to try.

i think you should try like floaters next to the boat to support the panels and they could also add a bit more wave protection and displacement to avoid expensive tipping

Love these videos, they always inspire me. Thanks for sharing! 👍

Excellent POC. You showed a catamaran as a better choice which I would NOT deny. A better choice again would be an outrigger trimaran with long and thin hulls for very low hydraulic drag. The outrigger struts could be furnished with very many panels, and potentially made to be fully or partially walked on. Good luck, I look forward to whatever you do.

Your boat videos are honestly my favorite of your catalog. All great stuff but these really do it for me. The unlimited range solar electric boat sounds like a dream

This project has come a long way and you've overcome a lot of challenges! Congrats on what seems like a successful trip despite the weather!

You should totally go bigger and make a solar powered boat you could potentially live on for a while.

With how much it gets pushed around in the wind it really feels like it might be worth figuring out a way of getting propulsion from the huge panel area you have. Not that it's a great hull design for it; but perhaps a self-aligning wingsail like Saildrone?

Thanks for this. I’m trying to get to Seattle because it feels more like home than here. Seeing all the port activities renewed my interest to getting there and I was greatly encouraged.

Love these trips you take with the solar boat. Even tho I've lived in Seattle my whole life. Your trip around lake Washington or this trip up the duwamish seem like such fun adventures. Thanks for filming it all! I know that little park with a "boat launch" off airport way too. The video doesn't do how steep it really is justice 😂. Glad u made it out safely

I cant believe it's already been a year since you built that boat. That was the first video of yours that I watched, and I remember thinking how crazy you were. My opinion hasn't changed but you have made that little boat into something awesome! :P

i think a mast would be a perfect way to be able to deploy the panels, and help support their weight. then you would struggle less, and can have a stronger support structure for the panels. and i might add, you should have some pontoons you can deploy on the ends of those wings. and also, it may be a good idea to have a permanent mount for the brackets. that way you wont loose your panels and benches in the worst case scenario of a flip over in bad sudden surf. i might also add, you could create a battery bank structure, such that they where both balanced, and fully secured. perhaps have them on the side walls to act as extra side benches, with a cover to lift up to access, and would seal the battery compartments from any water, period. lots of improvements possible, and i would love to see the evolution of those improvements, such that an end product could be made that could even be marketed. now, on that note, if you did eventually go to a roof solar cover, i would want to add stability mechanisms or blast and, pontoons to the sides. but i would also keep the transforming ability of folded panels, so then you could in theory have a single central panel on the roof, and a transforming flower like array built in, such that once deployed, the stationary roof panel is uncovered, and you increase the panel area immensely, without too much stability changes.

These types of videos you make are addicting, anything on the water especially practical ones like this (not small rc stuff) are amazing. I can’t get enough of this type of content.

Came for the solar energy stayed for the awesome excursion around the dock! Keep up the great work.

I love seeing where these adventures go; I wasn't sure what was going to happen when you did the boat restoration video all those months ago, but I'm always pleased to see when a new chapter comes out.

If you use flexible solar panel I bet you could use them as a sail, too ;) And save on weight. Even the rigid ones could work this way. Alternatively, could add a pontoon so that it has the pontoon in the water when its lowered, to take stress off the panel.

Awesome! There is nothing better than that freedom. Concerns with survivability in bad weather, and with the UV damage against longevity. But I think you proved that riverine work may be quite functional. Double sided panels will allow you to upright both panels for whatever, while still giving good gain from reflection.

I think the side mounted system is great! Better for trailering, basically twice the area compared to just a roof and it makes use of otherwise unused space. Very inspiring video.👍🏼

I'd like to imagine the blackberry guy looking out on the water from his yacht, seeing your boat towing along 6 kayakers, and saying to himself, "Yes. This is the technology I envisioned for the future."

Glad that starfish survived the near miss with the anchor ;) great video as always.

I foresee a day when a sail could be made of PV viable materials. The best of both worlds.

Great concept. Imagine doing this commercially. Like you are on a lake vacation. And you rent an electric boat with solar panels shading your on the roof. You can chill, fish or even speed along the lake - with no emissions. Thats so cool. And it would not even be that expensive boat to build.

Amazing video

I have an idea I think you'd like if you ever do a roof. You could make a roof that is held up by 4 (or 3) robotically adjustable bars, that attach to the solar panel with ball joints. Then have those bars auto adjust via an array of light sensors (or anything, lots of solutions), to always have your panel pointed at the sun!

14:56 That barges first stop is where I live. Cool to see it there!

Good you took the boat through fresh water to give it a clean. Great video.

Do you reckon you could make an automatic glider? It could fly forever

This is the kind of project I wanted to do at one point, unfortunately it's a bit pricey lll

Love the sightseeing around Seattle in these videos

Auto angle optimizing solar panel mounts would be rad. Optical scheme for detecting direction of the sun with respect to the boat’s current heading. Use that information to control panel angle - elevation and maybe twist. Also include a sea state detection logic to put the panels at a safe angle when encountering waves. Future project. Using the panels as a dronopad was fun. Looking forward to the V2 boat! Should have a fixed roof and foldout panels too..

His absolute refusal to say 'geese' keeps me watching.

Sorry we're late it got cloudy...

I love that you show us everything, including your failures and iterations to solve those problems.

I loved seeing all the marine wildlife from the sub’s camera!

🎉😂🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉

You’re a really clever fella, I’m impressed by every single one of your projects and tests. … so, I was very surprised when you used the (non) word ‘gooses’ 😂. Geese mate, the plural is geese 😁👍

What a great project. I've always heard flexible solar panels have a short life unless they are kept free from excessive vibration and flex. I just subscribed to the channel to see future updates and projects. Thanks for the adventure.

I love these videos. It's fun watching you learn, explore, work, and have fun.

I've wanted to do this with a small party barge pontoon boat for a while now. Have a solar array on the roof with the batteries in / under the floor. I was thinking of using high thrust trolling motors at each corner of it as sort of makeshift azipods. It's one of the many "someday" projects bouncing around in my head.

This is very cool. I agree with your idea that a displacement hull would be a better choice. The locally made (North Bend) EPCarry pushes 10-14’ rowboats to roughly hull speed (4ish knots) on only 250W of power. The owner there also wrote a blog post a couple of years ago about playing with solar boats. Interesting takeaways there (besides the hull form) are his use of high aspect and long RC airplane props. The ultimate conversion would be on a Duffy 21, the electric rental boats on Lake Union. They were designed by local sailing legend Bob Perry and are very efficient through the water. The standard motor and lead acid batteries could be greatly improved with BLDC motors and LFP batteries. The roof would give you lots of room for the solar array. I look forward to seeing what comes next in this project. I’m a big sailor but also love EV boats. We have a 10’ Gig Harbor rowboat that is great with the EPCarry, but something longer and with solar would be a fun next step.

That is a cool proof of concept. I've been wanting to build a solar-powered boat for the last two years but my wife won't let me (yet). My plan is to use cellular PVC sheets (screwed and plastic welded) with a roof. The idea is the swivel the solar panels to close the sides of the roof area. For example, in good weather, the sun-facing side would be down and the opposite side would be fully up so both are facing the sun. In poor weather, the sides could be brought down to protect the passengers. The panels on the roof and battery could be used. I think the panel on the roof alone would be fine, at a slower speed. It's important to have ballast below when there is more weight up higher. I would put a thick keel on it with the batteries sealed in there. Actually, I was thinking about Skelcap super capacitors, instead of batteries. Supercapacitors won't lose life over any number or recharges and they charge faster. At first, a battery will have more capacity but this decreases over time until the battery is eventually useless.

I love every video you upload. Thanks for everything, such an inspiration for all hobby types!

On the solar panels, i think that putting another hinge point in the middle of the solar panel would be a good idea. Then you can have both panels oriented in the sun simply by twisting the panel closest to the sun so it faces it and having the other regular. jm2c

i love the ish out of your videos, my dude. every single one is a treat. please continue!

A herd of gooses is called a "gaggle" of geese. It made me chuckle. Nice video and great idea of the boat.

Another awesome build.... time for a Lake Roosevelt test! Grand Coulee to the Canuck border would be a good test!

It would be interesting to see the difference in systems efficiency between these e-foil motors and electric trolling motors. I rigged up a similar system for dinghy propulsion several years back in Seattle with a 24V trolling motor and some lipo batteries. Worked pretty well, and they even have brushless trolling motors now as well. At least I knew the prop was close to optimal for the conditions. I didn't have color, but used the fixed panel on my sailboat to recharge them. Great series!

Incredible job! I have been dreaming about doing something like this out here in Florida. Definitely want to do a roof design so I can get out of the brutal sun. Now imagine this with rigid panels that can make 3x the power!

Large ships using the motor pod design run everything backwards to avoid that issue with the wake. One of Adam Savage's recent videos of him checking out underneath a new ship in drydock had a good explanation but it is basically to avoid the imbalance issue with the prop.

Great video ! Can'y wait to see the v2 ;)

I am from the Midwest where we have heards of cows and gaggles of Geese. Every time you say heard of gooses, l can't stop laughing 😂

Was waiting for this for a while, glad the video is finally here :D

Looks like a fun time cruising around and looking at stuff. I think you could build a roof for the solar panels pretty quickly with a TIG welder (or maybe MIG with aluminum friendly wire?) That's a skill that would serve you well going forward. The precut parts would go together really easily, or you could make it out of tubing stock. With welding skills from that, you could make a life-size tank with the tank tech you've been working on.

Thoroughly enjoying the solar boat adventures! Cheers man!

Peter Sripol did one with the solar panel on the roof two years ago. Solar panels are a pretty cool idea if you're not in a hurry.

We needed someone like you to actually go and do this kind of thing

if you would have used bifacial solar panels, you could have harvested the reflection of the water surface... please try in new video :)

Mounting solar panel on those bench is so smart!!

I actually think the best configuration would be a solar roof with these 2 panels as sides for the extra juice, on a catamaran hull though. That would give you a nice amount of power to either go faster or make the boat slightly bigger/heavier. But at the same time the panels could also make an enclosed cabin to shield you from rain if you do manage to make slightly water proof.

Bros --- quality time with quality dudes and quality wisdom --- and of course quality subscribers -- thank you for this wonderful video --- we keep learning from you cool dudes

Having owned one of the Wintech Cats for rowing coaching I can confirm that they are very easily drive and would make a great platform for your project. Just a lot more expensive than a renovated Boston!

Badass, im doing a similar project albeit snaller scale. Im just using a 10'2" plastic jon/bass boat with a 7' x 10' rectangular umbrella which ive tested at speed, in big waves, and high winds. The key is guide/support wires on all 4 corners which make it surprisingly stable. I just need to acquire some flexible light solar panels to mount on the top of the umbrella as im already powering it with a 700 watt trolling motor.

At 6:08 there is a wooden fishingboat with a norwegian flag! Neat! Your projects are nice to watch. Keep it up!!

I love it when I get to learn about a cool industry product or technical thing from a sponsor spot instead of just having the same trendy stuff that's in every KZfaq video. I'll make an exception for your Factor ads because having a quick meal available in the shop or out testing a project is much more interesting than just eating them at home 😂

This tech should be present in all life boats out there

A solar roof would be much less flexible *and* provide cover from the rain! You could make the legs fold up and tuck under the solar panels so that the roof is 'flat packed' for transport. They could engage in one receiver each built into the hull when up.

The most underrated part of the video is the CNC “fender cushions”

I watched an Adam Savage Tested video the other day where he was following the build of a big cruise liner - interestingly they had their portal props in FRONT of the skeg so they always had clean water flow. You could try flipping the motors around!

Cool video! You need to have life jackets (PFD) for you and every passenger on your boat. Easy way to get an expensive ticket.

The way this is set up, you could use a pull configuration for the props, getting clean flow into them.

this idea is amazing, you guys should definitely make a v2!

Flipping love it, 3k views in the first 12 mins, you're a legend Daniel

Congratulations you made it. You maybe make a solar mini yacht or a bigger boat with a sleeping cabin and sleep in it overnight if in the waters there isn’t to much boat traffic

What would be cool is a servo system or perhaps a motor pulley system to deploy the solar panels. Wonder how it would handle if you glass a kayak to either side of the boat? Similar to those fishing vessels in Asia. Guess a large diameter pvc pipe would also work. With the pvc you can build it into the ends of the solar panel setup so it also acts as a stabilizer in the water. Might have to calculate the spacing to not cover the panels in water when deployed

I think adding outriggers to the bottom on the solar cells would help. This reduces the load and moment on the seats. This could easily be done with pool noodles and PVC pipe. Sealing the PVC would add also add bouncy.

This was a great video, cool to see all that stuff.

I loved the industrial maritime tour. Excellent

I was watching one of Adam Savage's recent vids where he went to where they're building a Princess Cruise Line ship. They talked about the azipods on the ship and the props are mounted on the opposite side so that they don't have that problem with the prop mast. The props cut through the water and then the prop mast is behind them. The largest cruise ship in the world isn't the same thing as a Boston Whaler but still. It might work.

18:06 “Look at him he’s shy” *Proceeds to flashbang the crab* 😂

Towing the kayaks was a great idea. Great demonstration. Oh, and "push boat" ..... look it up.

Amazing project, mate. Keep rolling.

This dog ist the cutest creature! Invite him/her more often. It's heartwarming.
