It was a fairly large platform, with the operator lowering the metal tip slowly. It would not be unreasonable to think that this system was secretly developed in later years.

The best solution would probably be to use a MASER to melt the rock in front of you (that way you directly heat the rock instead of having to heat some part of the vehicle to crazy temperatures), and then use some mecchanical means (like screws and things like that) to push the molten (or maybe just softened) rock around and then behind you. But managing the heat trapped in the rock around you would still be a huge problem, probably without solution. Maybe the only way arount it would be accepting that the main mode of operation for your vechicle is to mechanically dig through dirt or soft/loose rocks and only engaging the heating device for very short times to help with sections of harder rock (having to move past the heated section, proceed some more mechanically and then wait for a cooldown period each time).

I love the idea of taking something that whilst underwater is practically impossible to find, then putting that in rock where it leaves a perfect trail of the exact path it took.... 😂😂😂 And this alm9st certainly DID NOT happen. There is a reason that tunnels aren't dug this fast and basically its just not possible. With how 9ften the cutting head would need to be replaced, the amount of earth it would displace if it actually could move at a brisk walking pace co sidering even the most expensive and advance tunnel boring machines today aren't even half that quick. It's just not actually possible on a physics level. First the cutter would disintegrate and melt if it were moving that fast, plus they would have to stop every few inches to back out, change the cutter. Then get moving again. And if something that large really could go through rock that quick it would melt the rock, but would very easily melt the metal on the machine itself.... 😂😂😂

While there may be a possibility that a machine like this could be made to work in near liquid permafrost in Russia, as someone who has worked in hard rock mining and tunneling for 20 years, there's no way it could operate at any useful speed or as per the catchy animation at all. IF it was possible to use these methods, then every mining company in the world would be using them instead of the slow and laborious drill and blast methods currently in use. The best hard rock advance rates in a standard decline mine (6x5.5m) are usually 3 'cuts' per 24hrs of 5-6m advance each. Problem no. 2 is what do you do with all the 'spoil', or loosened rock as you advance? You can't leave it in the hole ahead of the machine, and you can't 'swim' through it... Problem no 3, how do you replace the cutting bits on the drill head while travelling at 7km/h 🤷 What cutting bits do you use? Most cutting tools on rotary cutter type machines are only good for rock up to 80mpa or there abouts, after which you need to change to drill and blast mining. Burning holes through the rock ahead with some kind of magical nuclear laser would melt the machine when you pass through it. Never happened 🙂👍

How America makes their DUMBs. But instead of digging out and disposing of the spoil, theirs use lasers to melt the rocks and seal the walls to a glass smooth finish that supports the tunnel.

[@strikingeagle9855]

**TUNNELS**

[@ccg40]

trains

[@ccg40]

subways

[@brianbrwa]

In the 1960's, the US had a nuclear drill design, but it left radioactive residue behind it in the walls.

[@christmassnow3465]

Boring through the ground is not boring. Imagine digging metro tunnels, or traveling through the dunes like the sandworm in "Dune"...

[@welshpete12]

Of the four mines that did not go off and was left in place . One exploded in about ( I think 1950) . By this time it was farm land and luckily no one was killed . It was thought to have been lightning that set it off.

[@generalolivervonbismarck393]

I wonder if they plan to ever dig down and remove the explosives from those old mines(or evacuate the area above them and blow in place)

"I am the underminer"

[@theyreoutthere.huntinggear]

Avatar did this too. That was cool.

Thermonuclear from a reactor? Everyone’s favourite black powder, dynamite? A little script revision and fact checking wouldn’t go astray. I can tell that a lot of effort is put into these videos, these mistakes do bring down the quality a bit though.

[@steveharrison9901]

And so we now know the movie ‘Battle beneath the Earth’ is actually a documentary. 😁 This must have been something discussed more than we think, the Japanese model kit companies took the idea and ran with it, I think it was Fujimi. Mole Tanks. Large and small. One even carried a small one-man flying disc for aerial scouting after ‘surfacing’ . Of course these designs were more ‘toys you build’ and were dripping with missile launchers and rotating radar antennas, very impractical and pretty impossible for underground travel. But boy was the box art exciting! ETA: wrong company, it was KSN Midori, it was called the Ultra Moguras. There was also the Junior Mogura and the Big Moguras. Oh wow and a King Moguras. I have fallen down a mole tank rabbit hole! 😄 KSN just loved making sci-fi tank toy/models it seems.

[@jimstrange3475]

How would that work? It seems you'd be able to hear it or pick it up on those earthquake sensors.

[@anthonywilliams379]

a conventional tunnel digger could be improved with the introduction of a reactor to supply power instead of bringing the power down in long cables, but the use case for that would only really be beneficial in say replacing undersea cables and pipelines with ones below the seabed

[@bztube888]

The grid beats any reactor, so it wouldn't be an improvement, it would only make it more mobile.

[@jesipohl6717]

don't worry about disturbing all the life down there, it's not like a majority of the earth's biomass is in the seabed or anything ((sarcasm)).

[@Chris-ok4zo]

Wasn't there a game with this kind of vehicle? Forgot the name, but it had something to do with volcanoes. Edit: Volcanoids was the name.

[@molybdaen11]

Also the "comand and conquer " series and of course planeteer.

[@RandomVideos66]

Am I the only one who actually wants to see one of these in real life?

[@toothpickofdoom1294]

Nope I want to ride in it myself

[@user-fc7is6jo2e]

Subscribed! I just found your channel and happily subscribed due to this outstanding video.

[@brianedwards7142]

How about a video about famous or unusual bronze muzzle loader cannons of history?

[@reggieziet]

I can only say one thing about this, and those who know, know: NOD for LIFE! ;)

[@molybdaen11]

Peace through power!

[@DOOT_II]

Kane lives in death!

[@kundeleczek1]

You have lost so many wars and still believ... pathetic.

[@Bellett64]

Pretty sure Krang had one of these in the Teenage Mutant Ninja Turtles cartoon!

[@Opisthocoelicaudia2]

I love how the auger in the renderings is rotating the opposite way it would to actually be useful 😂

[@Flint1408]

Hello! Love your videos! Could you make one maybe on the F19 concept and or on the B36 and its variants?

[@linusvogel7769]

Hey fae could you do a Video about the west german mbb firefly Programm?

[@Bayofthe91st]

So its a Subterranine ?

[@user-rm4jd8ep5y]

That was a smooth segue into squarespace

[@blackstealth8168]

you ever seen those machines used to dig subway tunnels. Yeah it takes years to dig through dense solid rock.

[@gabrielb9010]

How long did it take to animate the ground?

[@FoundAndExplained]

too long friend

[@gabrielb9010]

​@@FoundAndExplainedalso, Aviation Station is at 10.700 subs

[@zx3215]

Thank you :) I haven't heard of this Leviathan even though I'm Russian :) Next I'm expecting a story of an underground air... no - submarine carrier! It could carry naval nuclear submarines from one ocean to another under the ground where no one can detect them! Must come up with some epic name for this monster - like Admiral Kozlov (or would Kirov be more epic?)

[@willmcgo8288]

Subterranean Submarine Carrier-- funny!

[@anthonywilliams379]

self-contained drilling machines like this could make a return on other planets, since underground shelters would allow structures to be made with minimal materials and utilising the ground for shielding from radiation exposure

[@isoinic4575]

Also it's where all the oxygen is stored in molecules.

[@jesipohl6717]

it's gonna be so much fun to be a slave on another planet.

[@user-wz9kt7im2i]

hmmmm. As a former engineering student you woke me up. *sigh* I have a personal friend who designed the drill bit for the Mars lander.

[@huntergray3985]

I had my post about it not being a submarine but a subterrane half typed out when...

[@matsv201]

Because material just vanish after the nuclear underground sub passes.. becasue its nuclear. This is USSR fan fiction as realistic as 50 shades.

[@Lady_hypoxia]

First and thank you for this amazing video 😊

[@21babydew]

As someone who deals with rock... its my enemy you dont go through rock at 7km/h id be suprised if it coild go 0.0007 km/h in some rocks and in others even move at all

[@justgeorgeous]

can i use a shortened version of this on tiktok and reference you and link back to this well done documentary?

[@DUBSTEP_KUSH305]

ITS A CUCUMBER BUT IT MOVES😅 THAT'S WHAT SHE SAID 💀

[@akashtsukumaran5420]

I have a question. How do you steer this thing?

[@BlooCollaGal]

Steer? You just point it West...

[@TimelineDunkley]

Thank for this information you gave me a idea💯🤔😁

[@user-yh3ix6lx1w]

"BEHOLD, THE UNDERMINER." 😂
