The total power of 2 motors is 4000W, the solar battery capacity is 300W. Boat runs from battery storage and solar panels load electricity when stopping, not running directly from solar cells! Tổng công suất 2 động cơ là 4000W, công suất pin năng lượng mặt trời là 300W. Thuyền chạy từ pin lưu trữ và pin mặt trời nạp điện khi thuyền dừng, thuyền không chạy trực tiếp từ pin mặt trời!

Can we write the dimensions?

[@Andy-df5fj]

How many watts are you running at full speed? How long does the battery last at full speed? How long does it take to recharge the battery with the solar panel?

Khoản bao nhiêu km trên giờ vậy

[@vantruongnguyen1702]

anh ơi cho em hỏi điều tốc đó anhua ở đâu vậy

[@aikenPL]

@@Andy-df5fj From the pure calculation looks like average lasting time is around 5min. Probably up to 10min if you are easy on throttle. I don't expect charging time to be less than an hour. Even if solar panel can deliver a lot of energy usually batteries can not charge as fast as discharge but of course it depends on type of cells. I'm curious how the reality is hopefully Sang can answer your questions.

If you use a mold release agent, with the right draft angles, you could reuse the plywood mold again and again to form many boats with the same design. Love that hull shape. Excellent work!

[@Nevir202]

Ya, but I think the point of all this was just to make a video, neither the mold nor the boat appear to have been built to last.

[@LoneBlackBear]

I agree, excellent work! Better than most of us are capable of. I also agree you need to streamline it and strengthen parts and hide/protect your gear. Just some ideas that would take nothing to update. 1. When you screw into things, hit it and all attachment points with some kind of marine friendly filler. Holes in a boat scare me. 2. Make a removable cover for running gear, those zip ties aint going to like all the UV. 3. A front screen/spray/wind/fish guard would be nice. 4. Use some of those pvc pipes to line the edges so you can dock, hit stuff. 5. Extra seating? Bring someone along! 6. Molded in storage spaces/12v TV, fridge, WIFI, GPS, its all cheap and small. 7. Save your mold! Or at least incorporate it into the design, I see floaty bits being torn off. 8. Come to my country, start a business with me making river boats, we'll make big bucks. 9. Make full paper cut outs for your molds so we can not start blind. We'll pay! 10. Keep it up and continue evolving, I love the pace of going from gas, to electric, to solar, now go hybrid! Thank you for your work.

[@Alrukitaf]

@@Nevir202 he looks like an experienced boatbuilder (at least fibreglass layups, and wiring up electric drivetrains), and no-one would spend the time effort and energy to produce an electric boat with solar panel and bilge pump, and then scrap it. He’s likely sold the thing.

[@The_Cat_Princess]

Thank you for your wonderful videos. I've been interested in boat making for a few years and have been self-taught, and this video is always amazing. The electric type that charges with solar has long been admired, but it seems that it will not be damaged immediately due to the burden of electronic devices because stable power can be obtained by storing it in the battery once and then taking out the power. I also want to make a solar boat someday, because I do not know how long gasoline can be used due to soaring fuel prices

I liked seeing the two motors wired to the same ESC, I once wondered about this and asked my EE professor about it. Just as you demonstrated, he said if the motors are identical in design then they should in theory be able to function together as if they were a single motor on an ESC. Gotta love electricity

[@sunnyfpv3694]

Also as you can see, both motors are tied to the same shaft ensuring both of them will run at exactly the same RPM

Fake video: 1 - The motor shown during the boat's construction is entirely different from the motor used at the end of the video with the boat operating on the water, which is probably a 10hp motor similar to the motor in this video: kzbin.info/www/bejne/eKuxp4amiZaJjbs. 2 - The two small motors at the beginning of the video likely don't even reach 0.5hp, meaning the motor at the end of the video is at least 20 times more powerful. 3 - This solar panel, given its size, generates approximately 100w, and could never power a motor with the 10hp potency shown in the video. More than 30 panels like this would be needed to power a motor with the potency demonstrated in the video. Not to mention that at the time of the test, the weather was cloudy, which means the video has several noticeable errors. It would be great if such a thing existed and were real, but it's not. These people only do these seemingly incredible things to attract attention and gain more views. Just this video alone has 2 million views. And that generates money for him. That's the real reason behind the video. vídeo fake: 1 - o motor que foi mostrado na fabricação do barco é totalmente diferente do motor que foi usado no final do vídeo com o barco funcionando na água, que deve ser provavelmente um motor de 10hp como o motor desse vídeo: kzbin.info/www/bejne/eKuxp4amiZaJjbs . 2 - os dois pequenos motores no início do vídeo não devem chegar nem a 0,5hp, ou seja, o motor do final do vídeo é no mínimo umas 20 vezes mais potente. 3 - essa placa de energia solar, pelo tamanho gera aproximadamente 100w, e jamais poderia alimentar um motor com essa potência de 10hp. seriam nessessárias mais de 30 placas iguais a essa para alimentar um motor com uma potência que foi mostrada no vídeo. sem contar que no momento do teste o tempo estava nublado, ou seja, o vídeo tem vários erros notáveis. seria muito bom se esse tipo de coisa existisse e fosse real, mas não é. esse tipo de gente só faz essas coisas que parecem incríveis para chamar atenção e ganhar mais visualizações. só esse vídeo dele tem 2 milhões de visualizações. e isso gera dinheiro pra ele. esse é o verdadeiro motivo do vídeo.

[@Nasatchannel]

The above 2 engines reach 6hp, the 300w solar battery is only used to charge the battery when stopped or used slowly. When I run fast, I use a lipo battery to run. You can watch the video more closely. I apologize for making you misunderstand about my project. I hope you sympathize and thank you.

[@DL-kc8fc]

Great project! However, my extensive experience with photovoltaics tells me that a polycrystalline panel could produce a maximum of 10-15W in a specific weather, which is not enough to drive two motors with regulators. In this case, only the capacity of the charged solar battery was used. The photovoltaic panel only slightly and insignificantly charged the battery through the MPPT. This does not diminish the idea of the project, because these things really work as long as the parameters are met.

[@stonyfieldmotorsports]

Thats probably about 300 watts of solar, plenty to charge that battery throughout the day.

[@DL-kc8fc]

@@stonyfieldmotorsports Za jeden jasný nebo polojasný slunečný den dokáže tento polykrystalický panel vyrobit 0,6 - 1,2 kWh elektřiny - žádný problém. V této situaci (vybíjení motorů) a počasí (slunce za mraky) však příspěvek z panelů není významný - polykrystalický panel v této situaci (slunce za mraky) produkuje maximálně 15W, což v celkové spotřebě cca. 2x300W a více je úplně ztraceno. Energii tedy dodávají především baterie, které nedostatkem energie z panelu rychle ztrácejí kapacitu. Daleko lepší by byl projekt se stacionární nabíjecí fotovoltaickou stanicí na břehu potoka s několika solárními bateriemi. Baterie by byla připojena pouze k jízdě lodí (bez fotovoltaické střechy). Mohl by to být dobrý rekreační podnik...

@@BrianRoddaDesigner :) It doesn't have to have a gasoline engine. A fully charged 100Ah solar battery (most often gel) can really handle it. :)

[@Miodowski]

Hi Valen, I don't think you really have experience in PV. I'm renewable energy professor in university, actually there are pv panels up to 600w, this specific pv is 300w, it is not providing energy directly to the engines, it is just charging the battery, it is the battery that works as a buffer what is powering the engines.

[@DtssavNet]

There is no way that boat is moving that fast on those 2 brushless motors. If they were capable of 1000 watts each, and I doubt the are, that would be 2.6 hp. When have you seen a small boat with a 2hp motor go that fast lol. I am guessing the motors he has in the video are maybe 500 watts each so more like 1.3 hp. Good luck going anywhere with that, not to mention the solar panel can only provide 250 watts peak sun.
