I saw you did some poses for the Tech Ingredients 2021 calendar there.
hes on a boat!!
@@buddyguy4723 He's outside, further than 100m from the workshop!!!
Hello
You know he is a proper scientist from the way he dressed for the beach.
@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.
Very cool but you did plant the seed in my head about hydrofoils
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! th-cam.com/video/ieigm2t9apk/w-d-xo.html is a decent fix though
6:17 "draw me like on of your french girls"
I wonder if that deck's more buouant than the door.....
Honestly this guy is so good at what he is doing making these videos that I give thumbs up before I even hit play
Same.
same for me
Your comment deserves the same,Well done.
Me too, we already know is going to be awesome.
YES MATE!
Been looking forward to this for months.
You deserve your fun and success. A great example to others that knowledge, hard work and a little skill makes things happen. Well done!
If you could arrange it so the spacing between the pipe mounts between hulls was the same as the spacing between fore and aft pipe mounts on each hull, then you could plug both ends of a pipe into one hull for easy transport.
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)
Making us plebs over here jealous!
I'm glad the boat was such a raving success, it looks like you had an amazing day out! Of course, we would have expected nothing less from our favourite Main Presenter.
I would stick 2 paddles below the platform - just in case, and because there is room for them =)
Good job btw!
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.
MP, I actually like episodes likes this every once in a while where you casually showing your creations in use. It's cool!
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
That was great to see one of your projects out in the world for all to see, and the genius you all put into it. That was fun to watch, thanks for sharing your adventures.
I don’t know if I’m in a minority here but I’d much rather hear the sound of what’s going on, especially the motors than some cheesy archive noise. Great Channel and incredible projects but not keen on the music. Thanks for considering if you do. :D
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 TH-cam 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
I discovered this channel just a week or two ago, and have been binge-watching all the videos. Really awesome content. I like to imagine he is a retired engineering professor, and thinking there should be a course in which students are allowed to to free range projects like this channel. Brought me way back to my ‘human-powered submarine’ days in college.
I simply love it! Gives me the chills every time a new Tech Ingredients video is up. I noticed how little drag those thin hulls make, just as you predicted. Said it in a previous comment but this reminds me of my dad at work(He was an absolutely brilliant engineer/naval architect) Keep up this awesome content!
Recently moved to the beach/intracoastal and found myself thinking about when we'd finally get an update on this project. I am not disappointed after the wait, amazing as always MP!
Finally! Thanks for the update!
Interesting to observe how cleanly the bow wave moves along the hull in this calm water, and also the wave interaction between the demi-hulls.
As I know your channel, I guess we'll see another update with the technical side of this practice test?
How pleased are you with pitch stability? (I'm thinking of what this boat would do in rougher waters)
Did you make any performance notes? A little empirical kW output vs. speed graph would be amazing ;-)
Man! I have been longing for an update on this boat!
Now to watch it.
I really enjoy your videos. They are truly enlightening and I’m grateful that you and your team take the time and patience to share your knowledge and ideas with us. Thank you.
Looks like you had lots of fun! Great work, putting together your own boat and then having fun using it! I love your TH-cam channel. I always get excited when I see new posts. Take care. B
I really enjoyed watching this project produce that highly functional water craft. WELL DONE!
I feel like a canopy made out of 4-6 130w solar panels wouldn't go amiss here...
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.
It's so nice to see the main presenter being water proof and having some fun in the water, not all delicate machinery can tolerate that!! Also I see a big potential of fun in building a bigger version of this awesome boat!!
this was so cool...finally watching our professor having some practical nature fun...love this channel.much love Portugal-Lisbon
Ah yes, the video I've been waiting for for a year.
Me to. But...now it is there...I enjoyed it. Thanks for showing. Now the next step in TH-cam 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.
Been looking forward to hearing how fast it goes, how much power it drains from the batteries, its range on the one Tesla module, and how well those model airplane propellers worked. Were those the original trolling motor props I saw in the brief moment the motor was visible? Hope the next boat video is more like your other ones. The boat seemed to go fast enough to enjoy the weekend well enough. What if you wanted to go camping and put some solar panels as a sun-shade, how far could you go each day? The idea of a tiny-house or camper on the water that doesn't use gasoline and can move from place to place for free is intriguing. Do you think that sort of thing is affordable to an ordinary person?
Well, this dude just built a house on water and set out from Kaunas to Marseille th-cam.com/video/A-eg4j0k8pc/w-d-xo.html I don't think there's any footage of it in english though... Here is a tour of the complete boat th-cam.com/video/eqbb0Pm7Vt0/w-d-xo.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. th-cam.com/video/9Ho0M21pbvM/w-d-xo.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
love this man thanks for the info, my dad used to work at a boat factory in the 80s-90s might start builddingf some river cruisers in my town .
Nice to see you guys out having some fun on the water! Can't wait to see the 60' unit built that you sail to Tahiti.
"Wear something aquatic"
Tech Ingredients:
What a beautiful lake.curious if you got a GPS speed while out on the lake.
It was great to see your creation float and run. To hear and see the application of the science in a build is awesome, to see it in application is the seal that the science is sound. Thanks for the video and will be watching for builds in the future.
Thanks for the boat ride! Now I gotta go back and watch the build again. I've been waiting for this!
I can't help but think of The Lonely Island's _I'm on a Boat_
Nice job! Are the RC propellers holding up and are they efficient? And when will we see you put hydrofoils on there?
Looks like a smooth, quiet ride on the water has been achieved.
Bravo!
Good on ya! Wanted to see it in the water; did not disappoint. I'm also impressed with how stable it is stern to bow with 3 men onboard.
Love Vermont! When I was a teenager my family used to rent a cabin every year on Lake St. Catherine, another one of the state's beautiful lakes. I was looking forward to seeing some test results (cruise and top speeds, current consumption at various power settings, longevity of the pack, efficiency of the R/C props, etc) and see those numbers compared against your calculated projections. May we see those results in a future video?
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?
The impeccable fit and finish is a jarring contrast to the profoundly innocent hull shape.
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 ?_
I have been waiting for this for a long, long time! Thank you
Amazing to see it in use! Congratulations on such a successful project...as always!
What are the water handling characteristics? Do you know what speed you were getting at different power outputs?
It's knots very fast.
@@gyrotech777 I see what you did there!
I see a design-flaw: that boat doesn't seem to require a person to be on it to propel itself. So if you drive it and fall off, it will end up driving itself away from you forevermore. Should either have some kind of (low-effort) lever that has to be held down, some kind of sensor for if a person is on it (could even be some kind of waterproof wireless identification chip), or (the annoying way) a short timer that requires constant resets (so it will drive away from you, but not further than maybe 1 minute of boat-travel)
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.
I actually applauded out loud, guess I thought I was at the movies. Thank you for taking me along.
Don't applaud at the movies you look like a hick.
Thank you for the follow up, watched you build and waited for the launch :). Bravo!!
A few questions:
What was the wattage of the motors? What was the top speed? How long did you run the motors and how much power did you use? What did you notice while underway? What would you have done differently?
What I noticed: There was constructive interference between the hulls. Extra buoyancy forward caused significant aft trim. You seemed to have designed this with aerodynamic principles in mind, which makes sense, but in practice with displacement hulls you want the finer section of the hull forward, kind of opposite of the optimum aerodynamic shape. This allows for better wave piercing as well as creating a smaller bow wave, which would help reduce the constructive interference and decrease the amplitude of the bow wave.
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" 🙄
I'm not a boat guy but that's beautiful. I was a little surprised to see it run right through the other boat's wake without seeming to notice it- very cool.
Did you design it to make the wakes from each hull touch the other at the extreme aft end as at 8:15 ? I'm guessing that keeps hull friction low. I also really like how they form a peak at the center. ;>)
Like some of the other commenters I anxiously await performance numbers- runtime, speed and so forth. It looks deceptively smooth-running: faster than it feels.
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...
Love it! Needs a huge deck with many umbrella fixtures on all sides, to adjust for the sun, folding chairs, cooler, and removable siding to keep stuff and kids from blowing off the E-swim platform. Wonderful!
A great presentation of the project, its technical aspects, branches and future prospects.
Have fun , good luck and success.
Stay healthy!
Thanks!
I’d love to see you do a series on hydrodynamics, specifically hull design. I was fascinated by this cat design, but I’m in the market for a fast, stable, and comfortable, live aboard catamaran, powered by electric motors, and instead of a traditional rig, with sails, an automated kite-based affair, like some tankers have started using. Just planting the seed...
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
It appears to be super stable, time for some more floorspace. It leaves almost zero of a wake. What was the runtime you are getting out of it?
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.
Looks like so much fun! Am jealous... Looks so smooth and does well in choppy water as well.
Absolutely love the observations and simplicity at its best...
The effect of hull speed is clearly visible, also the bow makes a very deflective wave. Not quite sold on airfoil sections yet... catamarans often have the max camber @70% from the bow
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
How long before we see the heavy lift drone? Please
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! :)
Waited so long for this! Pumped you guys got it on the water
Thanks for your effort in popularizing science and engineering. This channel is amusing, educational and satisfying for me.
Thank you!
I was just waiting for him to crush those coke cans with magic
There’s software to make rc planes, boats, etc. I wonder how hard it would be to get it working with the tesla boat?
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.
Watched the build of this so seeing it successfully test out on the water is very pleasing, looks great.
This was the follow up I was looking for! Keep it up guys! I'd love to see some more in your brewing adventures too! Maybe some mead!
3:15 I see you're also considering pure Newtonian propulsion but honestly the speed at which reaction mass gets ejected at seems to make this not really practical...
I've loved sailing forever. I look forward to seeing it under sail power.
Must be an amazing feeling using the boat you built! What a great project!
I can just imagine how soothing it must be to cruise on that. No engine noise, just the calm of the catamaran breaching the water.
Instead you get to enjoy what sounds like a pop radio station circa 2014
That is an awesome little craft. The only thing I would love to see on something like this (as well as every bloody electric or hybrid electric car) is all upward and even sloping surfaces covered in solar paneling. With the cars they could be recharged while your driving and especially parked while at work or anywhere during the day and save heaps on how often the engine has to cut in to recharge. In the case of this boat it would ideally mean extending the deck area but, it would somewhat reduce the current drain on the batteries and any time spent stopped or just drifting it would be actually topping the battery back up. I'm actually curious how fast something like about 1 kw of solar paneling alone could keep this motoring along at with just 1 person on board.
I do find it hard to believe you could build a neat bit of water traveling gear like this and not even be using it regularly, that's almost criminal.
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.
"About a year ago..."
What? No, it's only been..... _F***_

The water movement against the side of your hull shows a good example of a displacement hull and center of lift/ floatation......cool👍
I've been waiting for this!! Thank youuu!!!

That's a hell of a wave front you're generating. And the wave collecting in the middle too, that's interesting. Have you looked at: www.caeses.com/ ? I've just started studies on hull designs, my interests are in sailing. (I'm from/in Tampa, Florida) I like cats, and am considering one for a workaboard. As an Information Developer, and with a GNU/Linux powered display, keyboard and internet connection, I can do what I do.
Love your work. Thank you for sharing.
check out the open canoe sailing group on facebook. you might like it. there is always a lot of interesting convos going on in there. im trying to get into canoe sailing but my issues are i dont have much wind here in GA and i want to cary me my cousin and backpacking gear. so im trying to optimize.
@@Zaku186 Thanks for the tip.
Man, I’ve got to admit it, that boat is really sharp. The draft is minimal and would make a great California Delta fishing craft! As usual......
THANK YOU!!!
Sure and I agree. That's why the motors were hinged and fixed in place with soft aluminum wire.
THANK YOU for the upload . This video has me convinced on some doubts I had ... oops sorry for that ! 💗💗💗👌👌
You're welcome!
I think this has to be the worst musical choice in any Tech Ingredients video I've ever seen... bring back the theme tune!
Also - has it *really* been a year? That means it must be two or three since we were promised a follow-up on magnetohydrodynamics in a couple of weeks! I keep hoping to see that used as a boat engine, alongside the hydrofoils.
"On this episode of The Whitest Kids You Know..."
I'm just kidding because I'm jealous, cool boat. Throw some reclining lawn chairs up there and you have a decent mobile dock, maybe even make the floor space bigger and get a patio set!
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.
Hey, don't worry about it. Remember, there is more than one way to take that!😉
@@unlokia wow you completely misunderstood what I wrote and why... The Whitest Kids U Know is a TV show BTW
So nice, just a main presenter and friends of a main presenter having fun on the lake.
I found the next video! Awesome! haha. I was hoping you had taken it on water.
I just wish you didn't use that stupid teenage autotuned singing for the background music! :)
Yep, made my ears bleed!
You guys are the Wright Brothers of electric boats. I’m an engineer and love this🤗
Great to finally see that in the water - can't believe it was from a year ago! Looks great :)
Beautiful lake.
Finally! Great to see a demonstration. +1 for some performance specs.
been waiting for this... thank you, really inspiring
Excellent! I love the "mach diamonds"!
This is awesome, great job! Must feel awesome to ride around on a boat you built yourself. Especially without the smell of 2 stroke exhaust and the noise of a gas engine. Combining this with your drone power supply for a hybrid gas electric system would be super cool... maybe even a couple solar panels for trickle charging... charge up the batteries and cruise around enjoying the water. Boating is so fun, especially at a beautiful place like this. 👍
❤️ I love it when things work, looks beautiful... well done. The sitting position looks comfy too
A horizontal hammock comes to mind, with a bluetooth controller for lazyness hehehe
Congratulations! Keep up the good work!...
The fruits of your labor! Love to see it!
Wow that looks so fun, and that lake is beautiful.
The only one video I didn't learn much from, but was nice to see you kicking it back for once and enjoying yourself. That lake beautiful it almost look like it's in the wrong continent.
That was the point. We can't be all work and no play.😀

Might I recommend a project involving small ROV, so we can get you back to that beautiful lake next year with your Tesla boat?
Not a bad idea. We are adding the Tai long tail motor this weekend and the hydrofoil this fall.
Great result for a first test. I'm, sure you were pleased with her from the smile on your face. Very smooth quarter wave. Signs of much more speed potential when she is amped up (excuse the pun)
Great Job and very nice result.
Works great, good day out, beautiful scenery.
so stable and smooth on water, a pleasure watching it
Nice work! Looks like a lot of fun
I've been following you for months now and am amazed at the broad and accurate knowledge you have of so many subjects. I like how you explain so many principles of the myriad of topics you tackle (and put those principles to a physical demonstration!)
I was very interested in your hull design and the comparisons you have made to airfoil design. I too am trying to look for the optimum airfoil/hydrofoil shape that gives the lowest drag for the function it is intended to serve. I was looking at the time 8:15
which shows the hulls cutting thru the water and causing a "shock wave" disturbance where the water is divided and the vertical displacement of water ( potential energy is being put into that water to make that wake?) and after the water passes the hulls the wave from the left and right hull imposes in the middle of the craft making a large vertical displacement.
You laid out the principles of the hydrofoil design where the water is divided by the wider 9% section and is tapered to the stern, where the parted water flows back in and "squeezes" the rear hull forward (I like your analogy to a wet pumpkin seed squeezed)
I know the hull for the chosen NACA foil is only optimum at a small range of velocity, so I'm not sure what is the the greatest velocity you can obtain before drag increases at a geometric rate.
I see on modern ships they use a bulbous bow to divide the water instead of the typical slicer style found on older ships and most pleasure craft. Supposedly, the bulbous bow parts the water around the bow without wasting energy by imparting potential energy into vertical displacement and generation of a wake. But this bulbous bow is only effective up to a certain velocity (maybe 25 knots) .
Figuring nature has the best designs, most "cruising" fish have a bulbous head so the lower drag makes sense there. The other parts I think of is most fish do not have smooth skin and I was wondering if the small indents are similar to the dimples on a golf ball and reduce skin drag on the fish? Also, a fish's propulsion system is so unique and moves in a sinusoidal wave form and the drag on the opposite side of the propelling tail falls to virtually zero ( I'm thinking there is minor cavitation with the slightly negative pressure of the fanning tail causing the body to be squeezed forward like your wet pumpkin seed analogy)
Anyway fantastic work and I've learned so much from watching all most all of your videos. Please don't retire !!
Found a bug in TH-cam - I can only like this video once. Awesome job! I am so envy!
Been waiting a while for this! Excited!
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!
What a fantastic video, I am sure this is a day you will look back on In years to come with great fondness.
I noticed the catamaran produced an interesting “X” pattern in the wake under the craft.
Been awaiting this, fantastic!
Damn, your production quality is freaking amazing.
Beautiful! Here some of the inner city lakes don't allow gasoline but electric is OK. This would be the perfect fishing platform for these lakes. Looks stable enough to almost stand on. They've got big muskies in the deeper lakes.
