You might want to look up the late Francis Reynolds' "Hydrocopter" concept. It's been many, many years ago, but he explored a fascinating hydrofoil concept that looks, from today's perspective, sort of like an inverted quadcopter with independently tiltable rotors that touch the water on each rotor circle's tangent. By controlling each rotor axis tilt in 2 dimensions he was able to place the water contact patch for each so that the thrust generated could point in any direction in the horizontal plane. My Reynolds died in 2019, but he was a retired Boeing engineer who lived on Lake Sammamish (as I recall) where he proved out various model craft experiments. One of his early prototypes for what would become the hydrocopter used very similar paddle wheels to what you are using. His direct inspiration came from the way water fowl use their webbed feet as dynamic hydrofoils to get off the water so their wings can take over. If I remember right (it was the mid '80s when he was presenting this to a group) he said the paddle wheel version was difficult to control around yaw; that is why he eventually went with the tilted thruster design. Mr Reynolds held a number of patents. His full name was Francis Drake Reynolds, and he was an avid RC air and water craft modeller.
@@DSIVXX Next he's gonna make a V shaped, high speed tank tread to increase the stroke against the water, say, the entire fuselage is a paddle belt/ treadmill, with the paddle wheels on the wing tips for stability... A winged snowmobile with a 3rd center wheel you adjust up and down to change the surface contact (edited at 8:10) (I'm honest)
Same; at first I thought well this is silly but should be fun; but on second thought I actually think this might one the most elegant method to stabilize a agressive ground effect in choppy waters. I mean sure you can try all kinds of fancy active control with big surfaces and super fast actuators... but 'paddle wheel goes brrrrrr' is just really hard to beat in terms of simplicity and reliability. I think if you really designed a craft to make the most of this method I think that might just win you a Nobel for having officially cracked small scale ground effect vehicles (thats a category right?)
Daniel was the guy getting silky smooth drone footage back in the day when the rest of us were getting footage the looked like it came out of a blender. So naturally he's upped his footage game again!
When they made the sidewinder missile , on each directional fin control surface they had tiny spinning wheels at 2000 rpm to keep the track from squirming
You could try triangular shaped paddles to get a smoother transition when the wheels plunge into water. It would reduce the bouncing over water. I love your experiments, science can be really fun!
How about angling them out a bit to the sides, and adding outriggers, to keep the spray away from the vehicle body?? This could turn into a super maneuverable vehicle and potentially pull actual high-G maneuvers on the water? 🤔
This is fantastic work. I feel like the high-speed paddle wheel is a real breakthrough -- they allow a much higher tolerance for error in the wing design and PID controls. I'd love to see you experiment with paddle geometries and see if produce more thrust or reduce spray. Also, the camera work was absolutely pristine. I'm so glad you're having fun with this.
The last bit about surfacing propellers is actually how the fastest V-Hull boats operate. They have air lifting strakes, and reverse chines in their hills, these let the entire hull "float" in essentially ground effect. All the while, the outboard or out drive is connected to the water via a surfacing propeller. These propellers are shaped uniquely vs a traditional prop and in some cases are designed to operate with the centerline well ABOVE the water's surface, and only thin section blades cutting into the water. It's a better version of your "high speed paddle wheel".
to prevent the water from kicking up, you could have the paddles be curved, which would help eject the water before it gets picked up. it would also push the water down, creating more lift to help it get off the water.
All the birds that I've seen coast using ground effect, have their wings bowed down. It must be more efficient. Your creation is so cool looking and futuristic. I wonder if this technique would make a good amphibious vehicle.
With that camera you have your own stock footage maker and put up all of your stuff run forward, backward and mirrored, and I would buy it all. That is a helluva camera setup and you are makin fine use of it.
Beautiful west coast winter. Out here on the east the river has finally frozen solid over. Getting a lot of snowfall so no ice sailing. Going to have to experiment with skis instead
My intrest in ground effect vehicles is actually driven by the possible real world aplication in the Stockholm archipellago and Baltic sea travel. Ice in winter obviously impedes the usability of boats and ships. Things go slow or not at all in winter, which causes a lot of trouble. Beeing able to use existing infrastucture for boats and ships also makes this vehicle type an attractive idea. Main drawback seems to be they give a bumpy ride when the sea isn't frozen and not quite so calm.
Maybe rear mounted paddle wheels could work? It seems to work for rear wheel drive buggys that can pond skip. And the record for a motorbike driven on water is nearly 2km
As soon as I saw the first few seconds of this video I immediately stopped the other things I was doing. Brilliant idea. Scratched my brain engineering itch perfectly.
the video is better made and more interesting than anything the BBC has made in years, the machine is great and the effort put into it and how it was filmed is very much appreciated by people who do not watch television any more, cheers,
WOW!!! how your channel has taken off!! almost 700K subscribers!!! well deserved, you make fun interesting content that you narrate exceptionally well. thank you.
I think there's a startup opportunity for electric ground effect ferries. These ferries would not carry cars, but would carry TONS of people. What's more, at the ends of the trip, they'd become VTOL aircraft, so they could land on a large paved area next to the water and not require a dock.
Ground effect taxi. Pick up people and travel over water in ground effect. Actually capable of flight when unloaded? 🤔 this means it's faster when moving toward a pickup than otherwise.
@@dogefort8410 "Actually capable of flight when unloaded?" -- No actually capable of flight, period, but only does it out of ground effect for a short hop, so no ferry docks are needed. Just a patch of paved ground.
@@5peciesunkn0wn I'm talking about infrastructure costs and other barriers like that. It doesn't matter that they're so-so VTOL. They only have to do it for a short hop.
Those high speed HD shots are really a step up! It made it so much more fun to watch! I liked the "low production" from the old but that's really coool videos
Really world application for the paddle wheels: A stabilizing trolling motor for small boats. Kayak would be the perfect application. Using GPS you could keep yourself stationary right over your desired set point.
The boat you mentioned making at the end is very similar to how a zap cat boat works. It’s a very light boat designed for racing and when on plane the only thing in the water is the outboard motor.
You and Sripol are amazing... Your both brains could change mobility on the planet forever!!! Please do it ;) really enjoying the unlimited yet highly technic creativity!!!
great idea with the paddle wheels. I like the Sound when they hit the water. Little idea: What about Holes in the side of the Wheel to suck in air. Like breakrotors. They also suck in air and push it out though the middel to cool the Rotors. Maybe this could improve the liftforce.
That camera is so cool that I'm surprised it wasn't the focal point! You should totally try to find the rowing teams those people belonged to and the aircraft company and give them copies of these sick shots.
screw air effect! lets get an hour long breakdown on that camera setup! holy crap thats cool man. that cable based dampener gives me some ideas of my own. great stuff as always.
We need a cross between a paddle wheel boat, a tank and a centipede. I can just see 20 paddle wheels on a articulated body being an absolutely phenomenal watercraft. That's sarcasm if you can't tell but it would definitely be fun to watch.
Would it be possible for you to make an entire video with just awesome shots from the high speed camera, set to just like chill music? That would be super cool and relaxing.
That’s is truly genius. With the personal interest and ground effect vehicles, I’ve been watching this channel for a long time. Regardless, that is a truly next level development!
Super cool. If you're really interested in crazy paddle wheel nonsense . . . years ago, I saw a prototype of a fast paddle wheel boat that was basically a little Boston Whaler that had four smallish wheels, two on each side, that didn't have paddles but had rubber tracks strung over them. Maybe 5' front to back, wheels maybe 15" diameter. Like a tank built for water. The tracks had paddles on them, and they steered by varying the speed from side to side. It planed easily at speed. Never saw or heard anything else about it, but it looked hilarious.
Nice shots. It's amazing how the new tech, materials, software and everything else pales before the beauty of an efficient, light, impermeable, self-healing, bird wing.
Another awesome project! Always get excited when I see you posted a new vid. You need more Lake Roosevelt and Banks Lake trips. Would be happy to provide transport on the water while tracking your toys.
Your content is always entertaining and thought provoking.... Watching this I kept envisioning the wheels on a backwards motorcycle like swing arm allowing the wheels to hang down to the water while pulling forward and up sort of auto adjusting to maintain contact with the water....
I feel like regular RC car tires mounted 2x2 like a car would do wonders. The paddles may cause more drag than wheels, and the front-back orientation can help adjust for pitch and roll, while minimizing jerk in yaw on contact with the water.
This video has solved a problem in my mind with the hovercrafts. I always thought it is not feasible to change direction sharply with this kind of vehicles but now I see that there is a better way.
Seems like the next step could be a hydrofoil design? The hull is lifted out of the water for minimum drag. A wing under water to lift the hull out of the water, and propellers can be underwater, possibly deep enough to keep clear of weeds etc floating near the surface.

The high speed stabilized camera with its own operator is so overkill and so awesome I love it😂😂

And crazy efficient. The coupling of a prop to water is way better than air or the paddles... Boats would flat *move* if they could fly 🤣
