Taking the Tesla Boat out on the water! 

hes on a boat!!

@@buddyguy4723 He's outside, further than 100m from the workshop!!!

Hello

The suspense from that is still killing me.

Also saw something on a hydrofoil kayak. This could be a good project idea too. (Also was plotting a 3D Printed Modular Kayak with this as a module, but i am shit at CAD lol) (Also went too deep into the rabbit hole of hull design and got lost)

Tell me about it! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ieigm2t9apk.html is a decent fix though

On conventional ICE vehicles? Absolutely, on some electric thingy with no computers? All that can go wrong is the battery dying early

@@EspHack did you reply to a deleted comment or are you confused about what paddles are used for?

@@Juksemakeren brrr brrr

@@EspHack well, that's exactly what can go wrong, or one of the motors dying or the prop breaking,or whatever.

@@satibel Or one of the motors could get entangled with some debris in the water and burn out or trip over-current protection on the battery. Wiring could get damaged and short somewhere. There is a lot to go wrong even with dumb electrical system on a moving vehicle.

That is a great idea

Good idea. Or you could add additional mounts at the right place so you’re not constrained in your design (if it matters, maybe it doesn’t)

Same.

same for me

Your comment deserves the same,Well done.

Me too, we already know is going to be awesome.

I wonder if that deck's more buouant than the door.....

@Jakob I don't understand the necessity and reason for "throwing shade" here?

@Jakob there are better youtube commenters than you, yet here we are

​@Jakob Did he ever claim he's the best boat builder on planet earth? I don't recall he did... yet he built a very good boat 😎

@Jakob i do agree with you, but its a nice ponton-rig on Electric.

@Jakob so if you’re a proper scientist or inventor you shouldn’t try to improve anything because someone else already has a good design out. oh you also can’t say you have a better design because someone else already claimed their design is better. Your way of thinking is pathetically stupid.

Yes of course fun day out and all but the data, the data!

@@pakde8002 The data is coming, still in process because of the low badge project.

@@DarthVader1977 That would mean "...you are creations in use." Hmm... I must ponder the theological implications. Oh wait! Never mind.

@@Membwayne you* are* casually showing

nah use 360W panels - "moooarh powah" - ha ha.. then this thing will really Zip along -- >2 kW.

@@kadmow Who makes those? Sun power?

Oh yeah. Next step.

I dunno, "promise you won't let me drown" are pretty fitting lyrics! HAHA. But yeah, you're right.

I totally agree

I agree. I do video editing and more and more production is cutting music out for the same reason. People crave realistic sounds and visuals over montage style music drops

Microwaved Soda Thats really interesting, so people are asking for a closer depiction of reality over what was considered higher production values? I have to admit I have my own reason for preferring the real sound rather than music 2k other RU-vid channels are also licensing. I’m blind so when music is played over the action, its like the action stopped. If you want a giggle, try watching this video with your screen switched off or your eyes closed, its not very interesting at all lol. If people are asking for ambient mic sound instead of montage music thats nothing but good news for me. :D Thanks.

@@andylane7142 it's true. Also, over the next year watch channels start using shorter and shorter intros and with short natural sounds instead of actual production music

Well, this dude just built a house on water and set out from Kaunas to Marseille ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-A-eg4j0k8pc.html I don't think there's any footage of it in english though... Here is a tour of the complete boat ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eqbb0Pm7Vt0.html It doesn't go fast at all, but it goes. The pontoons cost him 5000 euros, after that, he "didn't count"

Beat me to it. I was disappointed by the video to be honest. There are so many questions left hanging, at least a few of which could have been answered in this video - like, how did the prop perform (even just an opinion). Also a stability test would have been easy.

I think my original thoughts on the rc props came to reality... The trolling motors ran out of torque to spin those big ol props... Just my 3 cents, but then again I do come up with clever solutions now and then with a screwdriver and a roll of duct tape to hold a door open... 😉

I like what was done in this video and here is a different approach, this guy did a combination pedal paddle and solar. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9Ho0M21pbvM.html

Nine Hundred Dollar Luxury Yacht Hey, great ideas, I don’t know if this builds on your thoughts but I was imagining it would be possible to build a mast for a sale where a single mast emerges from the hull which can swivel on a bearing, a meter or so up it would fork into 2 and continue up to its regular height where a sale with solar cells are printed and can be turned 90 degrees perpendicular to the water so it can collect energy while the boat isn’t running, it could assist while running as a regular wind sale which would still collect a little energy while running especially at the beginning and end of the. Day while the sun is low in the sky so hitting the sale with a high incidence angle (hopefully correct term).The sale is suspended between the 2 forks btw. I think it would be tricky to engineer a lightweight mast capable of holding onto the sale in higher winds when its looking directly up at the sky behaving like a wing but it seems this could be quite easily automated to sense stress and reef itself, mechanisms for doing that have existed for decades, just not automated. If motors were built in though it would be also possible to track the sun as it moves across the sky for maximum efficiency which would be needed because the solar tech that is printable isn’t very efficient I don’t think???? Anyway, just a thought. :D

Did I miss the part about where they say next week they are testing the first foil package? Please don’t make us wait another year!

Me to. But...now it is there...I enjoyed it. Thanks for showing. Now the next step in RU-vid style would be the equivalent of " put a turbo on it". Soo...half the height of the pontoons , most of the time 2/3 was above the water. Next step one actually Tesla motor at the front of the platform and a large driveshaft backwards, like in Thailand. Now put arduino controlled hydrofoils on it. One in the back and two in the front for better cornering at high speed. I just had to say it. A lovely silent boat at low speeds and a beast at high speeds...still economical at power consumption.

It's knots very fast.

@@gyrotech777 I see what you did there!

Things are quite different at the surface versus being completely immersed in a fluid.

To some extent that's true, however this platform is designed to operate as a self stabilized, wing elevated hydrofoil and needs buoyancy forward so that the aft end of the hulls, which remain submerged, have minimal drag.

@@TechIngredients and what about the other questions?

Horizontal fins at the transoms can give the desired lift without adding much drag. Like they use on those hydrofoil surfboard things. Add servos and you can adjust on the fly ;)

"A few" 🙄

Ditto. Also it looked like a glimpse of the props revealed standard trolling motor props, not the RC props discussed in the original video. Were they too weak to deal with the 1,000 times greater density of water versus air?

I suppose it is also a shame that they didn't add a platform low enough to dangle your legs in the water, could have had one behind and infront of the main one (also helps when getting coke, I guess). Cause it is quite nice to do. And might include a short ladder to get up easier when swimming. Also feels like padding might improve the boat a lot. Not padding it in its entirety of course, just enough to have comfortable resting positions, both lying down and sitting (the latter would prolly use the lower platforms, so you get a backrest in the form of the upper platform + padding).

All good ideas and that's the point of the project, an easy to assemble platform that can be modified to fit a variety of applications and powered by many different systems.

Tech Ingredients it's on a lake; you'll be able to find it if it goes free range!

feha92 He could just wire in a standard kill switch like all jet skis and many power boats have. Clips on your life vest, or a belt loop, or whatever and if/when you fall off it pulls a plug that disconnects the ignition. Cheap, effective, and unobtrusive. No need to reinvent the wheel.

@@jc5445 Good idea you came up with! A wire that disconnects when subjected to force should be a much more reliable system than some wireless token that could kill the boat any time it loses connection, or could easily accidentally be forgotten at home. Such a wire also has no need for pockets, and possibly even could be made to work without a need for clothes.

Actual I was surprised at how much wake it leaves. I was expecting less.

I was basing it on the wake that the chase boat was throwing out, but for the design of catamaran boat with two motors I have no idea if it's good or bad.

That hull shape is just fine. Racing sail cats Re very similar, if not more rounded. But considering it's bent plywood, it's perfect.

But it is SO sophisticated . Aerodynamics VS Hydrodynamics , propulsion VS resistance ..... There is so much to learn here , I can't wait .

@@tiberiu_nicolae If you watched the first vid. you can see the vast difference in the two . Applying the principles of physics above the aesthetics of form (streamlining) , I think he has shown a complex blend of high and low density fluid Dynamix . The wake motion in this video says it all , to me . And there is surprising stability for the amount of weight to the displacement .

Main thing to be careful of when dealing with fluid mechanics is the Reynolds number and the knudsen number. Other than that, the working medium doesn't matter a whole lot. I believe most NACA airfoil designs would render comparable results, as their specifications and performance characteristics are normalized wrt dynamic pressure.

_innocent ?_

Watch this . From the beginning he lays out all information on design of exactly what we are after . I am patient and wanting . Good things will come from this , too many people want this to happen . I'm sure he is aware of Sky-Sails and the downsizing efforts for automated units for 30 to 60 foot Cat ranges. Good things on the horizon !

Your beautifully executed hulls are so simple, one might think they lack something, but look at these instagram.com/p/CEemEpoBtdY/?igshid=6ikfdbnbk90h

Mark , we are on the same page brother . Wasn't that wake amazing ? He explained it in the first video as to how that worked , and damned if it didn't ! I love Science ! Predictable like NOTHING else in this current life

@@inmyopinion6836 I have to go back and watch that video (again) The old memory ain't what it used to be...

No kidding, I've been curious about that for some time...

Only another year or five

Cut him some slack, he's modifying the heavy lift drone so that it can take the weight of the Tesla Boat, fly it up into space, land it on Mars and then allow him and his crew to sail the Martian rivers; these things take time! :)

You have to compensate for the different performance of foils (air and water) at different sizes. Look up "Reynolds number", Froude number" and "chord number". It gets complicated... If the software can handle scaling, it should be fine.

I’ve thought that so many times. I’m glad to see someone else is with me. All those modern sensors like giros, accelerometers magnetometers and insane processing power on a tablet could and should be used to make a drive by wire system where you give a command for an action to happen rather than turning a wheel for example until you are at the right angle, why not have the sensors doing that stuff accurately now its all so inexpensive. In fact its so inexpensive you could afford multiple sensor sets at each extreme of the boat, mix in GPS etc and the tablet could handle everything including prop trim, power management, everything could be automated, even multiple hydrofoils at front and back for example, maybe stability control. Anything and everything. Lol.

@@535zzlayer You could do that already. Satellite internet exists. It wouldn't even be that hard. I mean start with a regular boat for one thing.

@@535zzlayer lemme guess, also powered by blockchain(both currency & inventory/purchase deals)?

@@markfergerson2145 I'd think most software wouldn't care about what engine you have, if you just want to move by gps and accelerometer/magnetometer/gyroscope. though I think with the current setup, using a tank drive software might be the most appropriate. but anyway, you don't need to know physics, you need to know how to steer and go forwards/backwards, and where the boat (or whatever you're planning on putting on autopilot) is, then you can adjust using the sensors.

the hull form is really bad

Would love to hear your guys' thoughts on how the design could be improved. Not being sarcastic either, I would really love to hear what you're thinking!

@@AtimatikArmy depending on what you want to achieve planning og displacement hull?

@@oscarohn Ultimate goal is highest top speed on a budget built, low powered, say sub 200 pound electric craft. Most likely trolley motor powered with APC RC airplane propellers as I believe they are the most efficient (diameter and pitch TBD). At least that's what I'm trying to figure out personally... Any knowledgeable feedback on idea hull design... planing, displacement, catamaran, other, etc (besides hydrofoil... for now)... would be greatly appreciated! Cheers

@@AtimatikArmy think i would recomend flat or allmost flat bortom monohull. Easy to build with flat panel design. Does not handle waves as well as other designs, but it is sufficient for many applications. And it is fast. We built a 3 meter flat bottom from 3mm aluminum, did 13knots on a 6hp mercury

Do you know the size a solar panel should be to produce 1Kw confortably.... Quite bigger than the surface of the roof of a car!

@@SilmarilS79 Actually when you take the bonnet and boot into the equation you'd do that easily. Besides, who gives a shit about a precise "1 Kw? Any power from solar would help save wasting fuel starting the engine like the silly little Toyota ones do. I don't give a shit if it's only a few hundred watts, it's STILL going to save you on fuel or power on your home bill. Did you somehow ignorantly miss the part where I said " all upward and even sloping surfaces covered in solar paneling."? I NEVER said just the roof genius.

Even if it just trickle charged the batteries, it would help.

@@AtimatikArmy Exactly! I couldn't think of the name before but those Toyota Prius cars were the main ones I was thinking of. They have improved since first release, the original ones you couldn't even plug them in at home to top up the batteries, it was ALL down to wasting fuel running the puny engine to generate power which I think was just plain bloody stupid. Now you can at least do that but if the upward facing areas all were covered in solar paneling it could put a lot of power back in during a work day if parked in the sun and depending on how far away work is may never need to start the petrol engine during a working week. I think it's criminally stupid not to take advantage of all that wasted energy. It's even going to probably be putting more in than you're using driving home on a sunny afternoon if you were stuck in stop start traffic and at worst is going to still reduce the drain by subsidizing it while driving anywhere during daylight hours. The simple fact they never thought to take advantage of solar on the Prius from the very first model tells me they're not taking them seriously as an electric hybrid car. Assuming a 1 Kw solar array a normal working day under ideal conditions for an 8 hour day should produce up to around 7 Kw hours which is a pretty substantial amount of power to drive home on. Johnny winger up there can keep paying for extra fuel, I'll go with something that actually makes some sense. I still can't believe an idiot would chime in with some bullshit poorly thought out comment like that, especially since I made sure to mention "ALL upward and even sloping surfaces " and stated that very clearly. I'm actually curious how fast something like about 1 kw of solar paneling alone could keep this motoring along.", I never said anything about a pissy little roof panel on a car producing 1 Kw EVER. The fact is though that if you did cover ALL those surfaces I mentioned I'm pretty sure you'd be in the ball park for that much power, maybe more. There's always got to be at least 1 whinger in the crowd.

Don't applaud at the movies you look like a hick.

What an ignorant comment. I don't even understand how the concept of referring to their skin colour would have anything whatsoever to do with the science. I'm talking to you about this *outside* of the subject, objectively. I'm not conscious of there being any validity to any reference to the tonality of one's outer epidemic layers being in any way logically connected to anything whatsoever. Congratulations, you've allowed yourself to be programmed. I don't mean this in a rude way to you, society is brainwashed, almost everyone is subconsciously programmed to be thinking, somehow, no matter how ridiculously, about the tone of skin. I just don't get it, why would it even be "a thing"? Don't allow your time to be wasted discussing such faux "intellectual" BS - step back, mentally & rationally detach yourself from any reference to anything related to skin tone even being inside your minds awareness, I mean LITERALLY mentally erase it, as you just waste people's time.
