All the people that put a thumbs down for this are just terrible! He has worked really hard on this project and deserves respect for such great success! Thank you for sharing these inspirational videos of your project and your family helping you
Your comment "It's so lovely to be grown up and still to be able to play and enjoy life" for me just sums up all the effort you put into designing and constructing your inventions and your personal reason behind it. Thanks for sharing your builds and especially for sharing your feelings, it shows in your videos you really enjoy playing and enjoying life. But maybe it's not the same for everyone and are amphibious vehicle enthousiasts a special group of playful grownups...
@@benhitchcock3057 Mythbusters did an episode on that. They setup a steel cable next to a vertically hung pig carcass then pulled on it until it broke. they tried a straight pull and pulling around a pillar to try and get the broken cable to swing and cut. At best they put a few slashes in the pig but nothing real deep. What happens is the cable slows down very quickly after breaking so it has little energy after moving very far.
@@benhitchcock3057 Been with a family of towers, I have seen first had what happens when chains, cables or tow ropes do when they snap under tension, its too gross to put here, but it isn't a pretty site. People die from those experiences. Enough said.
Wow... 1.1kN traction. That's really surprising and impressive! I hope the next test will be to cross the lake and back and measure energy consumption!
Did you try building up speed rather than just wide open throttle? A snowmobile in certain snow conditions will just dig a hole if you go WOT but if you increase slowly will go very fast.
Just like a basic paddle boat that produce mast worldwide the faster you paddle the slower you go it's because of the water the drag of the water in a vehicle that isn't made to cut through it will slow down at high speeds rather than Glide across the top
it pulls so hard because of the surface tension...Jason Madara is right, it can only be as fast as a paddle boat...just try to imagine this thing "rolling" on the water...fuild dynamics wont allow that to happen. the water is just to sticky!
@@maddmavic he never got to high speed though. He neared mid range then mashed the throttle. Like driving on ice. This is an issue of breaking traction, not drag or fluid dynamics impeding progress
When I first subbed I thought this channel was a compilation of multiple people's projects. I kept watching more and realized this guy built all of this stuff. You are really inspiring and amazing.
Maybe you should try adding fabric pockets on the tires. Pockets that fill with water when run through the water, and that act as scoops. They would only work in one direction of course. Perhaps that could give you the speed you want?
For most of these kind of vehicles, people just bind rope from the central hub over and around the tire to the inside of the wheel center, giving it a groove
The the mild wrinkles from the wheels caused over 100 pounds of force. You can put the smallest tread on the outermost part of the wheels and would probably get more then double/triple the force I bet!! Awesome work. This is great!!
Hmm if I asked a friend to come help chances are I would end up with a 50 something year old overweight Aussie bloke carrying a beer, in Scandinavia you have an endless source of lovely female helpers! lol. Nice work on the vehicle.
How feasible would it be to add some small nubs to the sidewall of the tires? High enough from the tread to not interfere with running on land but low enough to contact the water and improve traction. You'll always struggle to gain speed in water since faster does not equal faster. Every bit more speed is just increasing the thrust wasted since it becomes easier and easier for the water to take a path which does not contribute to forward thrust. Increasing the pushing surface (sidewall nubs or better yet mini paddles) would help substantially. You really wouldn't need much at all since just about anything is going to be better than the smooth balloon tires.
Adding eye-bolts on the inner and outer hubs would allow an optional bungie cord matrix. The bungies would deform the tires enough to form voids, which would create a paddle effect. This may give you added traction on land and water.
I'm looking forward to seeing a retest under load with a much stronger rope, I'm guessing it's got around 135-140kg of pulling force and with pressure adjustments I'm sure that figure could be increased, even just hot gluing some small fins across the tyres should increase that without causing a great deal of issues when on land. Really really interesting vehicle.
Years ago I noticed the same thing with Rologons in Alaska, that when on water and marsh and that not much power could be applied until you went from travelling over the water on surface tension to actually generating thrust by displacing water as thrust. Same would happen on soggy tundra with large, heavy and powerful Rologons that would start rip-up the seemingly solid tundra at higher speeds. Every surface has a surface tension that breaks-down at a combination of weight (displacement) and torque or shearing force and why large Rologons could travel about 25mph on roads but only about half that on tundra without doing damage.
Wonderful to see you both having so much fun, we all take life far too seriously don't we? so why not enjoy a ride on a large fully inflatable totally amphibious electric vehicle in the warm spring sunshine, I know that feeling you have, I have had that feeling many times when out and about on my home made electric vehicles as well, maybe some flaps on the wheels would help with it paddling on the water as it seems to wheel spin when applying instant power, I am not surprised by 100kg pulling force, this is as a direct result of the torque characteristics of the motors you are using, for instance a small hilti drill can easily break the operators arm if used incorrectly, with great power comes great responsibility :-)
Try small collapsible turbine buckets on the sidewalls to do a good impression of a Mississippi Steamboat going up stream at full flood . Thanks for this post , they are a a hoot !
Quite an impressive machine. At first I thought you were powering it with a couple of cordless drills so I was surprised to see all of those lipo packs when you pulled the cover off.
I would love to drive that thing around in Stockholm. I wonder if there's a special registration for amphibian vehicles. I suppose you get a high pull force because you are shifting a large amount of water with the large surface area of the wheels. But since water has so much give, that pull force won't translate into momentum right away. You probably have to build momentum more slowly to reach high speed. It's the same principle as for any propeller. I love this idea. I hope you go on to making these commersially because I definitly want one.
When i see her staying on the tensioned rope measuring the force i thinked "if it snaps and bounce on your legs sure as hell you wont try again." Two seconds later: "awww, jesus."
Hull speed is low because the effective water line length is that of the wheel contact patch, going any faster requires a lot more power to get over the bow waves. Really cool vehicle!
have you thought about maybe adding some sort of like mudflap with brushes or something behint the front wheels that would stop most the water climbing and hitting the back wheels ,just a hunch but if you could get it to work it might help with going faster. either way amazing work man you never cease to amaze :)
You could built a set of traction chains but with cord this Will create the same effect on water and Snow This will give you a lot more traction This vehicule is a very good idiea.felicitation. From Québec Canada.
I noticed that at full power the front wheels throw a lot of water at the forward moving part of the rear wheels, which must slow them down. At low speeds there is no such issue. Maybe try fenders on the rear of the front wheels? Might keep you dryer too.
Maybe you’ve already done it and I have missed it. But what would happen in worst case scenario if one wheel is catastrophically punctured? Will it still remain upright on ground, or on water?
the easy answer is depens on how good you are at balancing. the wheels don't have any weight in them, so the center of mass is always where you are. this means that if you loos one wheel and shift you waight wrong, the hole thing would tip down. Tho not sink, as even just one wheel is enough to hold the it afloat, well it, not you. you would be wiggling around in the water lol. So the the short answer her is, no it would not. also you would most likely be driving in circles.
Nekogami-Crystal Great answer. I figured it would not sink due to buoyancy. I was just wondering about safety if it happened and the water was very cold.
It becomes slower on water the more you press on the throttle because the g force is flattening out the outside of the tire causing it to become smooth and not move water as efficiently. A paddled tire would do wonders for you on the water and land.
Of course I can believe that just happened. It is a completely predictable danger for the rope to snap in that situation and for it to recoil and injure anyone inline with it. It is basic rope and chain safety to never stand near or in line with such a rope being put under unknown amounts of tension, because they do just that.
I have n idea for you. If you make and secure a cloth wrap around the tires, that also has slits evenly spaced around the tires... you could in effect slide in a formed piece of material, fix it in place, reinforce them and have paddles on your wheels. You wouldn't be sitting and spinning when you get on the throttle. Or a cheaper alternative, if the adhesive would hold is to just adhere some rubber to your tires in a manner that they look like scoops (sand dunes tire style)
If you would make some kind of scoops that stick out of the contact surface of the tires, you would get way more traction and make it way faster, if you make them out of the same or similar flexible material would be best.
It would be interesting to put a hydrophobic coating on the wheels and see what happens, it might increase your speed but lose pulling power, also might splash less.
You should try a version where the wheels have soft pockets that expand from the water flow and scoops water when it goes forward. Perhaps that could make it go faster? It should still be possible to drive on land, as the scoops just stay collapsed then.
I'd think a version of this that folds would make a great rescue vehicle; it'd be compact (i.e., fit onto the roof of a emergency vehicle), reasonably lightweight, could be launched into the water without a boat ramp, and could function in difficult terrain like swamps and on thin ice (maybe? having control over the wheel inflation might help).
It looks like that under full power the front tires throw water onto or in the path of the rear tires causing drag. When using low power the water disperses before getting to the rear tires. You might have better luck staggering the tires or just using rear wheel drive when accelerating. Either way cool invention good luck in the future.
I feel like hydraulic disc brakes would be better because the cables on regular brakes will eventually rust. I know it would be hard to line up the rotors for bicycle but maybe it would be easier if you something like motorcycle disc brakes. Bicycle disc brakes are basically just mini motorcycle disc brakes, some even use the exact same fluid. I can see why you would go with the caliper method though as it allows for much more room for error/wiggle room. Also I still think you should create an optional inflatable shell/cabin that uses the heat from the electronics to warm the inside so you can go out at night, in the winter, or in the rain and all it is is a thin clear bubble with zippers for doors or to attach it to the car. That would make that perfect for military/search and rescue missions.
Seems like the high static force is due to the wheels digging in to the water, which makes it harder to go faster because the wheels have to push through or lift themselves out of the water they are digging themselves into.
Also for boats, there is a theoretical ‘hull speed’ which is based on the waterline length. Since the waterline length is 1-1.5 meters, its top speed is under 3 kph
Any plans to change to Ackerman type steering? Pieces of corrugated radiator hose in the axles would be perfect for leak free air supply through the steering joints.
i feel like the Wheels need some flexible rubber pockets, optimally slanted and evenly spaced all around the perimeter, somewhat akin to an old water mill .. to better catch on to the water and provide better traction/transfer of energy,
is the wheel material pvc coated vinyl? if not, i'd be curious to know what it is and if it has held up against springing leaks. i've worked with the pvc coated vinyl and it doesnt take well to bends/folds and i feel like it will fatigue and fail in short order due to the denier mesh fabric within the vinyl that makes it less pliable. thanks for any info. cheers
set up a hydro foil you can lower and see if you can help lift the front at speed. Like you said it has lots of power so a little drag from a ski shouldn’t hurt
if you want more thrust you could try putting a kind of a paddlewheel on the outside of the axis. btw: having the car connected to a fixed object with a rope totally changes the angle of thrust. the rear wheels create a forward force at sea level and the rope pulls back at around 1m above the sea lifting up the front wheels. if you measure the power consumption i bet the rear wheels do most of the work and sink deeper into the water.
Others seem to be wondering what I am, if you had some kind of paddle type pieces on the outside of the tires/tubes, wouldn't you push more water, therefore creating more traction?
perfect for ice rescue! if someone falls through the ice this thing only needs a "water level" platform. it would be great if it could be lowered and a passenger could reach our and grab a person or even small animal
High spin is causing Cavitation and in air and water it's a killer to it will kill all your speed. If your wheels had inflatable paddles your low end pull power would go way up Now Which wheel do you cut your fish bait on?

Never stand in line with a rope, chain, or cable under tension.
Why come papa?
true, it might cut your hands or legs, take care
She was lucky
Questionable Impact man that force of impact to her could be questionable
She's lucky it snapped at that point. In the middle or near the car could have caused bad injury.

Was about to say, that is a bad place to be, over the rope, and then SNAP!
I was thinking the same thing before it happened as well. If the other end snapped then the girl may have gotten a nasty surprise.

I always think of that one Top Gear episode where James gets a really bad concussion from the rope throwing him over
Wow... 1.1kN traction. That's really surprising and impressive!
I hope the next test will be to cross the lake and back and measure energy consumption!
Yeah, and that divided by four(eight), through moment in thin plastic sheet...
its shocking to me, to get that kind of traction on water with plastic sheet. Must be some sucktion or something going on
Did you try building up speed rather than just wide open throttle? A snowmobile in certain snow conditions will just dig a hole if you go WOT but if you increase slowly will go very fast.
yes there's so much torque that it's cavitating under the wheels. building up speed should work
Agreed, build speed. I feel like it will end up creating an air barrier between wheels and water once a higher speed is achieved

To get up to full speed, I think you'll need to apply gradual accelleration, as Thomas Greenall suggested.

U are genius man where were you until now marvelous inventions
Tiptop created! What a good man you are. Bravo! Makes fun to see. Tank you alot. LG from Germany

he can add 4 pockets, 2 in one direction 2 in opposite. And it might work for going forward or backward
maybe adding some form of small ridges to give the weels more traction in the water? not sure what kind of glue would be durable enough though.
For most of these kind of vehicles, people just bind rope from the central hub over and around the tire to the inside of the wheel center, giving it a groove
Just awesome as always 👍🏼💪🏼👌🏼

Magnificient work again, Axel!
Have you tried driving over obstacles? I would not be surprised if it would gently climb over the park benches that were near the lakes edge?
Wow! Awesome video! Really cool inflatable car! 👍😁
What a outstanding project! Enjoyed it from start to finish.

You're such a creative person. so glad that you share the projects you come up with. very inspiring
Seeing the inflatable car transition and drive on the lake is very satisfying. Great work!!
You should add flatt half shell cover all around the wheel to the wheel that way you can translate the speed to traction
MookMajor 👍
The the mild wrinkles from the wheels caused over 100 pounds of force. You can put the smallest tread on the outermost part of the wheels and would probably get more then double/triple the force I bet!!

Good friends are the ones that help you with your crazy projects. ;)
How about offset scoops on the rear tires, say 45 degrees to provide thrust yet keep it from digging downward.
How about an outboard motor?
Must be able to drive on all terrain, I suppose. Can't do that with scoops. Also needs to be inflatable, that's kinda the point of the project.
Congrats ....it performed great!
110 kg pulling force surprises me too! It should be sufficient to fight some potential wind.
Not necessarily...The wind may lift the car. And then there is the steering... Looking forward to watching it perform in wind :)
It becomes slower on water the more you press on the throttle because the g force is flattening out the outside of the tire causing it to become smooth and not move water as efficiently. A paddled tire would do wonders for you on the water and land.

Great video, thank you. I would consider a 'snow chain' type affair of rope. It would be great for snow and water (I hope). Good luck!
Good projects. Just take lot more precautions to avoid injuries.
Now combined this with your other invention and you can fly over water and have the ultimate landing gear
Love all the LIPO's in the car :D
I think what is happening here is the Magnus effect trying to pull the wheel further into the water creating more drag.
You should try a version where the wheels have soft pockets that expand from the water flow and scoops water when it goes forward. Perhaps that could make it go faster? It should still be possible to drive on land, as the scoops just stay collapsed then.
I'd think a version of this that folds would make a great rescue vehicle; it'd be compact (i.e., fit onto the roof of a emergency vehicle), reasonably lightweight, could be launched into the water without a boat ramp, and could function in difficult terrain like swamps and on thin ice (maybe? having control over the wheel inflation might help).
It looks like that under full power the front tires throw water onto or in the path of the rear tires causing drag. When using low power the water disperses before getting to the rear tires.

Congratulations from Canada!
this has more torque in water than some cars have on land
Any plans to change to Ackerman type steering? Pieces of corrugated radiator hose in the axles would be perfect for leak free air supply through the steering joints.

Wow that looked like a lot of fun
wow you seem to have the worlds Lipo battery supply on board.
LoL
I wonder what he'll do next with that supply.
I was thinking that rope was too small and then snap!
Too many geniuses in this world!
set up a hydro foil you can lower and see if you can help lift the front at speed. Like you said it has lots of power so a little drag from a ski shouldn’t hurt
if you want more thrust you could try putting a kind of a paddlewheel on the outside of the axis.
btw: having the car connected to a fixed object with a rope totally changes the angle of thrust.
the rear wheels create a forward force at sea level and the rope pulls back at around 1m above the sea lifting up the front wheels.
if you measure the power consumption i bet the rear wheels do most of the work and sink deeper into the water.
How is it in the wind?
Even my sleeping bag cannot be that packed
Others seem to be wondering what I am, if you had some kind of paddle type pieces on the outside of the tires/tubes, wouldn't you push more water, therefore creating more traction?
simply amazing fun . I would love to see you bring it to Bondi Beach Sydney and drive over the waves !
I was literally thinking "oh man she's standing right over that. What if it snaps?" And sNaP
She got lucky with where the break occurred. She could have had a very rude slap if the rope broke elsewhere.
and this is why we have OSHA and workers insurance!
Amazing! Very cool vehical. All the Best from Russia!
perfect for ice rescue! if someone falls through the ice this thing only needs a "water level" platform. it would be great if it could be lowered and a passenger could reach our and grab a person or even small animal
Awesome design. Does this type of vehicle have any towing capability the traction and drag would be very interesting.
sykt kull bil! trur du det går å bygge den i mindre skala, men fortsatt brukbar til å kjøre for 1 persjon?
I love it,,thxs for being crazy ,,that's when life is fun,an it looks like you-all are enjoying this,,thxs,,,
For more speed in the water you may have to resort to secondary propeller of some kind
Had the drive wheel been on the rear tires only you would have gained speed. Try this method and you will be able to go faster with high speed
Very nice work, congrats on the progress.
kind of like a pedal paddle boat. if you pedal top speed it slows down. awesome build. paddles or fins mite help "traction"?🍻
Great job buddy!
High spin is causing Cavitation and in air and water it's a killer to it will kill all your speed.
If your wheels had inflatable paddles your low end pull power would go way up
Now Which wheel do you cut your fish bait on?
You deserve more views my man
Rope breaks. "Can you believe that just happened?"
Yeah I can. Anybody with a brain can believe that happened.
Lol
wow u must be a genius.
The unbelievable thing was that the car had so much more power than expected.
There's a saying that states "The best steersmen are always standing on the shore".
This would be perfect for space exploration
