thats awesome.

I served in the Navy with a dude from Juneau. I thought he was full of it when he told me about the screw driven tractors his family had. Then he took me to AK on leave and showed me. Those things are wild as hell. That's also when I saw just how big moose actually are.😳 Jeebus!

That sounds awesome, there’s so much ingenuity that goes into working in such harsh conditions, I bet you have some great stories about this experience.

Cool

@@SkunkApe407 The size of a moose is arguably the bigger shock. Went big game hunting in Alaska with a buddy from Force Recon who is from there, and saw an elk fairly close up. I just safed my rifle, slung it on my back, and said, "what the fuck is going to kill that?!?!"

XD

Are we sure it didnt have to turn around because Jeremy and James secretly stashed Richard onboard while he was asleep?

How did politics stop it? Did they not have the necessary Visa's to enter Russia? And was this done for TV? If not what paid for it?

I was trying to swim across the lake as a kid. Halfway I got tired and had to turn around and go back.

@@petergerdes1094 There were 2 russian helicopters waiting for it at the international dateline who turned them back. The guy who built it is interviewed on 'Drivetribe' youtube channel 'This is where all Grand Tour inventions are made'. Not clear who paid for it, this was back in 2002.

@@petergerdes1094 Jeremy is on the ban list in Russia because of that time he made all those jokes about Putin not being able to perform as a man anymore. If you get my drift.

Liking just because Colin Furze is a complete nutter, makes awesome machines (the jet-propelled bike is a favourite), and somehow seems to find time to make KZfaq videos. I don't know how, after all that, he has time to eat or sleep, but he seems to keep going. 😁

@@Cameron655 Yeah, the dude is a machine. He has been pumping out projects while digging a tunnel under his house and he still has time to help raise two kids and do editing and such on his channel. My admiration for that former plumber is PROFOUND.

If the 500Kg wheel spinning 900rpm is out in the open and clear for all to see, everyone will know to be careful around it.

@@ldobehardcore precisely! Hide it inside a casing that's not capable of containing the energy released if it went boom, would provide a false sense of security, I believe personally.

Stupidity and carelessness was often a capital offence in those days.

Yes, that was an interesting boss fight too.

The Russian term for "screw-propelled vehicle" is "Shnekohod". I imagine the Shagohod's name came from that.

@@SeanMirrsen The literal translation for "Shagohod" would be "walks by steps", it was a common name for all machines with legs. "Shnekohod" means "walks by screws"

Spray it with bedliner

Nope, foam doesnt work like that, all types of foam soak in water over time. It doesnt sink instant but you have to remove the foam and put new in everytime the hull gets damaged.

@@jonasstahl9826 it depends on the type of foam. If it's foam like a spons you are right. But if it's foam where the bubbles are not connected to each other. Also there is a possibility to use "solid" but light foam without bubbles ( like styropor)

@@swisstestpilot In theory you are right, in practice not the bubble of "solid" foam like styrofoam break from mechanical stress that you have from a vibrating vehicle or by getting shot, also plastic is biodegradable, there are a bunch of insects and microorganism that can eat plastic, given that the walls of the bubble are very thin it doesnt take much to break them, even more when it frezes the ice crystal just poke through the bubbles Put a piece of styrofoam in a body of water with an ecosystem like a pond or aquarium not a bucket in your garage and the styrofoam will soak up alot of water and break down over time. That is the reason why styrofoam cups or food boxes are coated. Also you cant just weld the hole up if it is filled with foam that can burn.

@@jonasstahl9826 styrofoam was just as example for a bubbleless "foam" type, not for chemical and mechanical resistance, there are countless 100 different types of plastic for this application and some of them meet the requirements for such a vehicle as well. The point is that the vehicle should continue to function for some time (it may well be several days) in the event of being shot at or damaged. As with a car or airplane, it is clear that after a few years of use, parts (here this "filling" may have to be routinely replaced.

I pity whoever has to recover it the day after the lazy guy on site forgets to secure it so it won't float away.

@@absalomdraconis it was on a tether at each end of the craft attatched to a line at each side of the tailings pond. Does that compute with your snowflake brain ?

Less gravity is less force on the blades. One guy did put a sizeable dent in one of the stainless mesh wheels of the moon buggy though. He hit a rock at speed. Probably the coolest car accident ever :D

The one big advantage i see in this design is...see the tracks it makes on the mud/ dirt? why not make it bigger... and perhaps spray some concrete on the sides and hey why not add some concertina wire on the side facing the enemy?

I don't think gravity would meaningfully affect how one of these would perform. You've got a large surface area for friction to work over, and also importantly the propulsion speed will be limited by the screw angle and rotational speed of the screw. As for sending one somewhere, I actually don't think it's that impossible. Stick most of your equipment inside the screw, and it could make sense for that petroleum moon (Titan, maybe?). Have the screw be hollow and stick some digging equipment at the front, and maybe it could be a new design for investigating the subsoil of Mars.

The big problem with using this sort of thing on other planets right now, is that for all the benefits of screw propulsion it has a couple requirements. Those being, mass and power. Mass is necessary for the whole machine obviously, but screws specifically endure a lot of wear and thus have to be extremely sturdy. And power is necessary because for driving on anything that isn't water, the screws waste a lot of energy on friction - and the more mass, the more energy is wasted. And if you're going electric, which is necessary for exoplanetary explorers, you also need batteries, which are more mass, and even more wasted energy, etc, etc. Now take modern space exploration, with strict limits on how much mass you can deliver and how much energy you can procure. The further out from the Sun, the less you get out of solar panels. The further out from Earth, the less mass you have to work with. All told, it combines to make the screw-drive a very impractical choice at this stage of the space exploration game.

@@SeanMirrsen this just makes me ask if said screw could be made of local materiel... then again shapping it like a screw might be challenge

Wow you came up with this idea. You must be old

Lol

Another reason to hate this language

Dad joke level: 100

Yes, those are the best videos. And the supposed first German one in this video looked identical. I suspect it was a Fordson. No point of cloning it, they would just buy one, if they wanted to test one. The long version of the video shows the system attached to a car for city/town use. The video I found today says "concept". It wasn't. You could order the kit by mail.

They tried to use them Alaska, but it was just too cold. There is one in a museum in Fairbanks.

I knew it! My father long ago showed me the Ford screw drive tractor. He's a Ford fanatic and many of my family worked as engineers for Ford.

Apparently, it was a kit that just fit the Fordson tractor and a Chevy. The thing was: Armstead Snow-Motor kit, Snow-Motor Co. Inc., Detroit

Ah yes, the DESTROYER OF LAWNS! My Uncle had one for a while, it could rip the shit out of the ground lol. His tank wasn't nearly as destructive.

the front and rear screws have the same angle, that makes it redundant. reshaping the rear for higher angle to further accelerate water reduces the front screw efficiency. I'd say not very well

This is the perfect all terrain vehicle

screw drive ballast tank? sounds awesome, if very complicated

than*

Yeah he doesn't mention the real reason it wasn't used much in Russia; the thing was so rigid while driving it was murder on your lower back after extended use.

@@zysis : Semis have a solution for that- shock-mounted cabs. Though, admittedly, it would be better to isolate the rest of the vehicle too, since any moving parts will also suffer...

No they would not function like a wheel

they would function as a pseudo wheel but still tear up the ground beneath them because that's just how corkscrews work

Search "Erkanoplan" or "The Caspian Sea Monster"

I can move each arm/hand independently in speed and direction. Not sure if it is because I am a lefty or what, but it requires no extra concentration or effort for me.

Mars with all the rocks, screws all around the vehicle so it has no real top or bottom would be ideal. -It could tumble itself over if needed and do all kinds of gnarly things. I'm fairly certain something like that would outclass wheels of any design.

Kojima is an idiot, why tf does the metal gear have screw propulsion when it's supposed to go really fast? Screw propulsion is like the exact opposite of fast.

@@rubiconnn true but in terms of the timeline for the game being around the Vietnam War and the US testing similar craft it dose line up. Granted it may not be practical but it kinda look cool.

It would still produce a tipping effect though, so not desirable regardless. Some sort of sealing foam would be better, but you'd have to worry about it burning if attacked.

screws are my favorite locomotion method in crossout, once you get used to strafing sideways to peek around cover you can never go back to treads lol

Not really, more appropriate as a "plan b" utility vehicle, much like hovercraft. You can use them to access areas that you otherwise couldn't, easing construction of roads through such areas in support of better performing vehicles. Prefer hovercraft if you want more speed, and screw vehicles if you want to deal with hillier terrain.

The exhaust could def provide the pressure or a pump off the motor. It's a great idea and certainly viable. It makes me think of the SAAB with the track-ball wheels. That thing was incredible- able to go at any speed in any direction.

Or just fill the tubes with Styrofoam...still buoyant, but wouldn't take on mud/water.

Gotta be thorough

He doesn't mention skid-steer at all. I think he's a noob and probably has no clue of it in reality. Love driving the Bobcat. my favorite toy.
