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.

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.

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’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 YouTubers. Hall of fame for sure!

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!

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'.

Dude drove a boat with 3D printed parts like propeller... it's impressive

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.

22:49 "Keep sailing Bob!"

Im impressed at the ability to do this entire mission but he fails to understand that the hot food is hot every time he eats lmao

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.

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.

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.

In case you were wondering, the "missile silo" is actually a "beehive burner", a building used for burning excess sawdust from old lumber mills

That funny looking structure on the shore looks like an old sawmill.😊

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…

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

This film was like a short holiday, love all your engineering projects and the nature around your place. Greetings from Germany 😊

"Just gotta make sure you don't hit anything, but other than that you just hang out" lmfao hell yea

when the stranger rocked up and was genuinely curious and thought it was awesome, that was a real wholesome moment, makes me want to do this sooo bad
