Shallow parabola has low focus? I don't think so. The deeper it is the lower the focus.

porosity sometimes are good things, just look at plastic foam structure your third plastic actually remind me of structure of human bone lightweight yet very strong anyway great works i hope you succeed

Bothers of precius plastic, hi reclicling BOPP-5

Thd ribs and frame are way more dense and heavier than wood, therefore you must reduce the thickness of every one.

9:13 Most traditional sailing boats and cargo ships had ballast stone in the bottom and cargo is loaded loaded evenly and as low in the hull as possible so this never happens.

I haved watch it so many times by now, we can't wait to start building ours. Thank you so much for the inspiration ! 💙⛵️🙏

We are ready to start our Flipflopi sailing boat models now! ⛵️💙

No más plásticos de un sólo uso. Si a más veleros Flipflopi navegando por el mundo 🌎

You guys inspired us, you can be sure of that. Thank you for that! 🙏

We hope to be able to replicate here in Chiloé, Chile sometime soon. Keep up the good work!

Good project

Bravo equipo!!!....esa si es una buena tripulación. Excelente trabajo..... y el maestro Ali es el primero en saltar abordo 😂❤😊.

Team work.... congratulation guys, this is awesome 🎉

I love it 💓, this will be the biggest expedition ever ❤.... the whole world is watching, may the Allah give us more strength to prove it to the world that every slight smart thinking can work❤

Votes of thanks to Flip flopi for standing up to beat the pollution made by plastic, I know it's challenging but it's good to prevent too, I'm fully in support of this❤✊🔥🙏

Way to go and sail......and much more !!! 🤩

You do this for the whole world. Bravo!

When people take the responsibility in their own hands on a local level - it’s democracy. Please keep on taking care of our planet.

We wish we can help you build from here. Hope to start ours soon. Keep it up 👌

Great learning by experience....keep up the sails!!! ⛵️

Excellent initiative, keep on growing! 🌱

Wow super action from you !! But *CGM CGM* ..... Big boat mafia, linked with Macron's facist corrupted governement....

Hope you didn't pay much for that plasma cutting? Old mate controlling the height was unique but the cut's were terrible.. Although, can't expect a perfect job from from a homemade 'plasma table'. He was obviously, looking at the ground clamp, using a very cheap plasma torch..? Table was built well though besides the ability to control the height.

Design idea: (actually, two, which will depend on your system design intent) 1) The focal point will tend to spot heat, so instead of projecting directly onto the rib form, create a larger outer round tube onto which the focal area will project, with the form tube placed inside of, and offset away from the focal point, and interstitial void filled with oil, so the oil will be directly heated by the focal point, and distribute the heat uniformly across the inner form tube, basically a tube within a tube with the center tube open at the ends. 2) Perhaps even better, use only the focal point tube, without an inner tube, filled with oil, themostatically circulated via hydraulic hose to an insulated reservoir tank, from which hoses distribute the heated oil to 'jacket' of the mold, which would allow you to create any shape you want, or just heat beams for softening for bending, 'remotely'. This way your 'parts' need not be positioned at the focus, but perhaps on a table or the ground. You would have to allow for a bit of expansion in the system, but a coil of 19mm copper tubing is cheap on Amazon. That way you use your reflector 'thing' to heat the oil, transfer the oil to mold with a 'jacket', and you could have a huge, long reflector, and direct the heat where you need it, via the oil, while upping your overall thermal mass.

Great video thanks for sharing

It is a good job to come to south sudan

Great job, very inspiring !😊

Very colorful ! 🎉

Smooth ❤

🎉 Much success! It is something that I was looking for if the plastic could melt with the sun and I already found you that it is possible! I will also make my design to share it from Mexico!

The things are hiding only potato😂😂😂eating!

Plastic is by it's maturenot a rigid material so how Re you going to avoid creep changing the shape of your vessel. This is a serious problem in wooden vessels so it may be a problem here as well.

Cool!

Decarbonation, mobility, efficient project, cheers from France

What is the name of the reflecting thing you use for making parabolic mirror

Muy buen trabajo.....felicidades !!! 🤩

Jippie! 🥳

This is a great technique. Congrats !

1 in 5 fish has plastic in their guts Solution let’s make all the boats from plastic and get the number to 2 in 5 Imagine if every shipwreck was a plastic boat Then we have the minister for tourism in 1 of your vids explaining how his dirty plastic filled country will be fixed if the lodges don’t use plastic because yea it’s the tourists fault all the plastic in every back ally and street and beach that’s all the tourists that btw spend almost 0 time away from the lodge. How many tourists is Kenya having 50billion a year ? Liberal whites saving the planet😢 help us all we are doomed and channels like this have good intentions but make all the problems so much worse.

What temperature do you use for the welding?

How many tons of glue does the 60tonnes of plastic need to form this ship?

Wonderful work! 🤩👏

Wow ! that is so super cool! I love the colourful squares from the flipflops too :D

Wow! Whisky plank is in place! 👌🏽

Maybe also look into fiberglass to cover the sides not facing the sun.
