ACME made something similar back in the 1960's. A thin black disk could be laid on the ground and instantly become a tunnel to wherever the operator needed to go. This technology was used extensively to attempt to trap roadrunners.

No, the MOST unbelievable part of the Soviet story is that it left an empty tunnel behind it. Where did all those tons of earth and rock go?

[doltsbane]

All you would need is three seismometers and you could track such things even more easily than a submarine.

If NOD did not lose from GDI, we would have them as public transport by now!

[shariqhasan]

Soviets had some pretty crazy ideas even though most of them were impractical but still I respect the imagination of their engineers.

military really said "worm but bigger"

The Mole was my favourite International Rescue machine after Thunderbird 2.

6:55 TNT, which stands for trinitrotoluene, is not the same as black powder. Black powder, also known as gunpowder, is a mixture of potassium nitrate, charcoal, and sulfur. It's historically used in firearms and fireworks. TNT, on the other hand, is a yellow crystalline compound used primarily as an explosive material. While both TNT and black powder are used for explosive purposes, they are chemically different substances with distinct properties and compositions.

Considering that boring a tunnel with humongous dedicated equipment inclunding similar machine takes years and costs billions I cannot fathom what kind of stupid went into "military pays for R&D"

Something like this would be more practical for going through ice. I think NASA has plans for a small one to melt through miles of ice to get to Europa's subsurface ocean.
Tunneling through rock at the speed depicted in the video would be impossible not to mention how noisy and easily detectable the mole would be making it useless for offensive military applications.

Found And Explained’s alternate title in an alternate universe, “What happened to Water Subterrenes?”

Lights at the back of the land submarine is in particular helpful.

There was an old 1960's British kids TV show made with puppets called Thunderbirds, everyone age 5-10yrs watched it. As a humanitarian rescue agency with wild vehicles they had a digging machine called The Mole.
You could have just used footage from the TV show because the concept shown here is that close lol, even down to the scaffold to angle it downwards to get digging.

In the 70s I saw a documentary about constructions of the future in which they showed things that are commonly used in construction today. And one of the ones that surprised me the most was a tunneling machine, which was a giant tungsten tip that was heated to red hot and was capable of melting the earth and digging a tunnel, whose walls looked like rock crystal. 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.

[manoloorz]

Took me 7 years to realize that the boring company's name is a pun for tunnel bore machines 😅

[brunocesarcerqueira]

This vehicle reminded me of the Thanderbirds. If it were truly possible, it would be excellent for building tunnels, underground bases, and deep mining.

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).

[gagis]

I have one suggestion for you. Try to research the project of the former Yugoslavia, the supersonic plane "NA or YU sonic". I think it would be a good video. Because it shows how much that country was thinking about the future of military aviation at that time, and later with the collapse of the country all those people who worked on the project went to various world airlines. Just one example, they developed voice commands on airplanes, and all that at the end of the eighties.
I hope to see a good video about this
Greetings from Serbia✌️

Could you imagine the civil application for these machines. Like tunnelling transit tunnels or making pipelines.
