1. Cool design guys! Of course, the principle difference being that the satellites are in space and dont have to contend with gravity. But you know that. I see no shame in there being a "web" of a few thin support wires from above.

2. Let me know when you have a strong commercial model ready. Happy Holidays 😊

3. Groovy things are happening on your sailboat. Love what you guys are doing with the new style solar works.

4. Could you not add some fold out brackets underneath so that when fully unfolded it would better support it rather than all pressure on the hinges? Think like a table leaf that could still be folded back meaning you don't loose the space saving benefits you are trying to achieve

5. Great idea! Really useful to be able to optimise the surface area when conditions allow!

6. One suggestion, the solder points, wire to panel, in the SD card boxes should also incorporate a mechanical strain relief. Even one as simple as a wire tie binding the wire to the panel.
   The Sikaflex will offer zero mechanical protection for the wire to panel solder points.

7. Solar product design seems to be a natural fit and makes for some interesting episodes.

8. 😃👍👍👍❤

9. 👍👍

10. Keep plugging away at it. With each attempt you will either get close or learn something. I've considered using an inflatable dock with solar panels secured to it while at anchor. lol. But currently I just have a little Catalina 22 and no robust railings.

11. Looks awesome to me. Side note, I was whistling along at the end of the video without even thinking it, I completely nailed it. 😁

12. Very neat project

13. Does using triangles instead of squares allow a greater ratio of “total area when unfolded” to “total area when folded?”

14. Love your channel. I’m not sure about this one for a sailboat. Seems like too many points of failure. If you’re troubleshooting a problem, you’re going to be there a while. Go to shore and be away from the boat when the wind kicks up…. Stowed or not, you’ll be thinking about them. Fixed panels seem much more wind/sea resistant. Sorry for being negative. 😢

15. Very cool. Good luck with this. You guys are amazing.

16. My dad was sent to Cochabamba, Bolivia to teach radio to Indigenous enlisted soldiers of the Army. W2FFM found out the equipment needed to be in regular contact with Panama. He was also able to relay traffic from other missions that put him in a position to request any non-functional equipment he could include in his classes. He started radio when his older brother became fascinated with Marconi's wireless trans-Atlantic message to France.
    The mission chief lent him his C-130 for a month to collect all the things that needed to be repaired. Chief among them was a burned-out generator (just like the one often mentioned in MASH). So my job was to strip and "tin" wires of various sizes that he cut to length for various components. One day the skip (bounce off the ionosphere) was perfect for a couple-minute voice contact in England. many thousands of miles away. Cheers from Mr. Strip & Tin!

17. Each environment has its own unique solar characteristics. Whether that be heat, cold, dust,wind, snow, ice, salt, cloudy/overcast days, terrain, available space, geographic location and angle to the sun.
    Next considerations would be location and space ( boat, RV, cabin, homestead, etc). Followed by power considerations, hardware, assembly, mounting, cable runs, links and communication. Design compensations for number of overcast days: panel type/size/power output, mounting flexibility.
    Some unique challenges on boats, depending on size, age, panel support (wood, steel, stainless steel, glass, cloth), panels that are fixed, flexible (rotation or angled) boat construction material (fiberglass, wood, steel, aluminum, cement, composite, other): boom/sail shadow, underside boom clearances, new Vs retro for hardware access, cable routing.
    With panels in place, daily, safe task work access. Fishing, towing, anchoring, docking, storage. Cleaning and replacement. High wind kite effect.
    Most important is technical support and service when things go wrong or stop working. Moreso in remote areas to get spare or replacement parts. As panels and equipment age in extreme environments, parts will fail. When technology advances, more opportunities develop or can be taken advantage of. Sponsored supplier discounts.
    This project must have some initial design goals: costs, power, mounting location and method, flexibility to expand, versatility and access to technical support and spare supplies. In time robustness, durability, reliability. For now what are you hoping for over the existing one? There are lots of valuable lessons learned when doing something novel.

18. Please let me know when to preorder.

19. I personally think that this is the most impractical and flimsy project I ever saw. And all this for 100 watt? Waste of time!!!!

20. Love it, that you control the system with a Rasperry Pi. One of my favourite toys. 😁

21. 27:20 Seems that if you oriented the cells as you have done on the 4 outside triangles (i.e. aligned with the non-diagonal edges), you'll have a fraction more surface area than oriented as you have them on the inner triangles (ie. aligned along the diagonal). All the "white space" will be along the diagonal…which is shorter than the sum of the other two sides.

22. Love this! Big fan of solar.

23. Kika's right. If it works on a sailboat, it will work anywhere. Wonderful concept. And I'm sure the Greek Sea Sirens can't wait to flap their wings when you deploy your panels. Nothing like the ocean environment to test you best thoughts. I crew on a 36' Junk Rigged schooner. We're electric driven screw and fixed panels for the house bank. I certainly recognize your challenges and wish you the best. Very impressive and we anxiously await the trials. I told my captain to view this Step!

24. Very cool!

25. 👏👏👏

26. I would have thought a stern anchor would keep your bow into the swell and make that anchorage far more tenable. Loving the solar project, shows tremendous potential, especially for those of us who are not fans of hanging solar panels all over the boat.

27. what was that promo code for the couch?

28. HOW DID YOU GET YOUR HANDS ON A RASPBERRY PI? These are like unobtanium these days.

29. This is actually interesting. Been thinking to integrate as much unfoldable solar as possible for my boat as well.

30. You should get some van-life Chanels to try out the second run. Like a boat the roof of a van is limited on the real estate that can be used for solar panels.

31. I don't understand why all these triangles are better than a pair of rectangles which fold up on each other?

32. I dig it when Dan gets into a project…

33. Cool. I did a ton of work on miura based folding systems in architecture school

34. Interesting project and to be honest I'm surprised that some NASA contracting company doesn't already have this for off the shelf use. Thanks for sharing it and please continue to post. Very interested to acquire something like this.

35. Brilliant! Keep the dream, and thanks!

36. Very exciting stuff! The evolution of solar is more promising every day, and you're part of it.

37. If I understood right your wind indicator is battery powered and the battery is within the instrument that you mounted at the top of your mast. I was just wondering if you ever considered putting wires down through your mast soldering them in to your battery connections and then put a battery box and a much more readily available spot or figure out how to reduce voltage by stepping it down so we can run off your normal power.

38. Has anyone come up with a sail with built in PV cells? Or would it completely ruin sail shape?

    This triangle shaped panel makes sense…..if you need to have the smallest possible folded max dimension. But if you can get by with a setup that has a larger max dimension, a panel that folds up into a 4 ft long rectangle is simpler, lighter and has more cell surface area.

39. Dan and Kika,

    Merry Christmas to You and Your Family. I wish you the best, today and for years to come.
    Cheers and Blue Skies,,!

    Faithfully,

    James

40. Dan, a caution with wd40. It's great that it does offer many uses, but remember that it's carcinogenic and absorbs through skin. Follow it up with soap and water.

41. It’s an interesting project from a concept point of view but I struggle to see what problem it is trying to solve over what is already available in the market, and from experience, the simpler the better for anything on a sailboat..

42. Merry Christmas from Mexico , Feliz Navidad !🎅

43. I love this! Well done, guys.Thanks for sharing this tech adventure. So many applications.

44. I use WD40 also for cleaning engine grease from my hands after working on my car.

45. A Happy Christmas to you both. Really interesting video. I am also working on a new type of solar panel. So I am keen to see how this one comes out.

46. Merry Chrismas and other Holidays. Guess you do not do holiday wishes.

47. Merry Christmas and a Happy New Year and Happy Sailing 🙂

48. ok so answer me this where TF did you even find a Rpi theresa WW shortage at present

49. Interesting to see how this project turns out. Happy Holidays!,
