Harrison Dyar, Amateur Tunneler

Earlier this year, I posted about THE MOLE MAN OF LONDON, an eccentric British fellow who liked to dig tunnels. Well, the USA can hold its own in this category, thanks to Harrison Dyar of Washington, DC. Wikipedia gives a short account of his habit. This long account is much richer.

Dyar told the Washington Star that the urge started when he dug a flowerbed for his wife around 1906. "When I was down perhaps 6 or 7 feet, surrounded only by the damp brown walls of old Mother Earth, I was seized by an undeniable fancy to keep on going."

The Mole Man of London

For some reason I recalled recently the odd case of William Lyttle, the Mole Man of London, who dug out a warren of tunnels under his home.

Lyttle, originally from Ireland, inherited a 20-room property in the London borough of Hackney. In the mid-sixties he dug out a wine cellar under his home. Having done so, he said that he had "found a taste for the thing" and kept on digging, for some forty years.[2] He created a network of tunnels, wide and narrow, on several levels. Tunnels led in all directions, some of them up to 18 metres (59 ft) in length, and reaching as far down as the water table.[3] One excavation connected with the Dalston Lane tunnel, and the railway line.


I was intrigued to learn that 3 years ago, his derelict house had been renovated and repurposed! Read about it, with many pics, at the link.

Nuclear Tunneling

One of the projects that researchers at Los Alamos have worked on is a 'subterrene'. This is a nuclear-powered tunneling machine capable of boring through solid rock at high speed by melting the rock. They were granted a patent (No. 3,693,731) for this in 1972.





There's some info about this (as well as it's possible use on the Moon or Mars) in the book Terraforming Mars:

A means, however, of generating a glass coating on the wall, as a direct result of the tunneling process could be achieved by nuclear heating and melting, rather than nuclear explosive crushing. This latter idea has been explored at the Los Alamos National Laboratory under the guise of the SUBTERRENE program in which it was envisioned that the heat from a fission-reactor might be used to literally melt the rock around it - effectively, that is, tunnelling by the controlled use of a China-Syndrome meltdown. Indeed, a US patent (#3,693,731) for such a nuclear tunneling machine, was awarded to Dale Armstrong and co-workers at Los Alamos in September 1972. The patent application states, "this invention provides a rapid versatile economical method of deep-earth excavation, tunneling shaft sinking which offers solutions to ecological problems, acquiring natural resources presently inaccessible and access to an enormous reservoir of natural heat energy. These valuable subterranean sources include natural minerals and hydrocarbons, fresh water and clean geothermal heat energy".

The same technology was proposed by Joseph Neudecker and co-workers, in 1986, as a means by which tunnels might be bored upon the Moon in order to construct a subsurface transportation system. Describing their nuclear-powered melting machine as a SUBSELENE, Neudecker et al. calculate that a fission-reactor-heated, 5-m diameter tunneler could be made to advance by as much as a 50-m per day through the lunar subsurface. This tunneling, they argued could (indeed, must) be operated remotely. Importantly, for tunnel coherence and stability, the material melted at the front of the SUBSELENE would be extruded at its backend to form a glass lining on the tunnel wall.

Wikipedia has an article about the Subterrene, noting the rumor that the Soviets actually built such a device which they called the "battle mole".

The Cave Restaurant and Resort of Missouri

Alas, it closed in 2015.

When it was last for sale, a mere quarter-million. Call the realtor to see what you can arrange.
