Technological achievements of the past that cannot be properly explained

Robocops, Automatons, and Mechanized War Chariots of the Ancient World

  • 2,162
  • 13
They are immune to heat and cold, untouched by the elements, and can fly, mounting upward with a fluttering motion. They dwell apart from the chaotic world of man, subsist on air and dew, are not anxious like ordinary people, and have the smooth skin and innocent faces of children. The...

The Wrath of the Gods: GeoWeapons vs Mud Flood

  • 6,485
  • 27
It's been mentioned in various posts here and there, but I do not think we have a dedicated thread for this "liquefied dirt" phenomena yet. We are yet to approach any sort of understanding of our Mud Flood related issues where buildings ended up buried in the dirt. What if some advanced weapon...

Early 19th Century: Highway Steam Locomotives, Related Laws and Roads

  • 2,512
  • 21
In 1829 Hancock built a small ten-seater bus called the Infant, with which in 1831 he began a regular service between Stratford and London. It was powered by an oscillating engine carried on an outrigger behind the back axle. The boiler was vertical and made up of a series of narrow parallel...

Ancient and early 20th century Robots

  • 3,256
  • 24
A while back I ran into this 1900 Automatic Man. As far as I can remember, the robotic qualities were dismissed by a semi-elaborate hoax, where an electric carriage was used to propel the contraption forward. A walking automaton has been invented by Louis Philip Perew of Tonawanda, which...

1649 Vehicle a.k.a. Nuremberg Carriage By Johann Hautsch?

  • 2,328
  • 13
A celebrated mechanician called Johan Hautsch of Nuremburg in Germany built an ornate carriage in 1649. It is thought to have been worked by two men concealed inside, who turned the rear axle by means of handles. It is reported to have gone up and down hills, and steered around corners, and...

1886 Meigs Elevated Railway: 227 feet of BS

  • 2,776
  • 22
The Meigs Elevated Railway was an experimental steam-powered monorail invented by Josiah V. Meigs of Lowell, Massachusetts. He wrote an extensive explanation of how the railway worked, complete with diagrams and statistics, which was published in 1887. The weight of the train was carried on a 22...

Prague astronomical clock: Orloj

  • 1,540
  • 3
You would think a device of such magnificence and importance would have been heavily depicted by painters, artists and photographers over the millennia, but it appears not at least form a quick internet search, perhaps it is depicted in books, etc not online. The clock was first installed in...

Weather Vanes vs. Air Travel, and may be Flags

  • 3,709
  • 9
In my opinion the Weather Vanes mounted on top of the older, or "ancient" buildings had practical, rather than decorative purposes. To be exact, it was to show the direction of the wind to the pilots of the ancient airships. I understand that it probably sounds way too bananas crazy for some...

Pre-1872 Cerbere and Belier: what are these ships?

  • 2,020
  • 9
I meant to start this thread as soon as I had a chance to observe these two ironclads docked in Cherbourg, France. This photo was allegedly taken in 1882, if we were to believe the backside of the photograph, which could actually be a postcard. It's hard to say if any rivets were used...

1873: Russian Round Armored Ships of Admiral Popov

  • 2,430
  • 10
The existence of these two round Russian armored ships in 1873 does not appear to be a widely known fact. As we came to find out, information is not really hidden, for it is publicly available for research. Yet, certain things are simply not being disseminated. Personally, I found these round...

150 Foot tall "streetlights" Los Angeles 1800s

  • 3,735
  • 16
I am new to SH and have not posted yet. I have enjoyed this forum and have been reading everything. My first post maybe should be in the introduction area but I ran across this streetlight dilemma and needed to share it. I will do my best at posting photos, descriptions and links. Most posts on...

What are minarets really for?

  • 3,283
  • 10
Minarets are called manāra in Arabic, which comes from a word meaning fire, beacon, or light. This already gives us a clue to the purpose these towers once served: to collect and produce energy, perhaps emitting light from the top, or powering houses and buildings in the town around it. Minarets...

Flight - A Revised History

  • 2,931
  • 13
Something is clearly up with the history of aeronautics we've been sold. At present, the current narrative suggests that the Montgolfier brothers balloon was the first craft to successfully take to the air. The first free (non tethered) human flight took place on November 21, 1783, by science...

Hindenburg: Was Zeppelin technology a threat to the 20th century?

  • 9,363
  • 43
And that was the last time anyone ever saw commercial airship travel. No, seriously. It was over after this, after hundreds of successful flights and a track record for safety (pretty amazing that anyone survived that crash, they were clearly designed with safety in mind) airship travel was, on...

1893 Chicago Ferris Wheel: World's Columbian Exposition

  • 3,669
  • 7
The Ferris Wheel made its debut at the World's Columbian Exposition in Chicago, 1893. It was, of course, a big hit with fair goers, who enjoyed their first taste of this amazing ride that would become a carnival staple ever after. I knew these basic facts, but didn't really pay attention to the...

Viktor Grebbenikov & The Cavernous Structure Effect (CSE)

  • 3,399
  • 12
Recently, the work of a highly obscure Russian entomologist has become available to a much wider audience, a humble and quiet man by the name of Viktor Grebbinikov). His life work was the study of natural objects such as beetle wings, honeycombs, stalks of wheat, and flowers. Although he was a...

19th century Engineering Magazines

Just like with any information, its comprehension depends on which angle you approach it from. If you are ready to accept that semi-naked Ancient Egyptians built the Pyramids using chisels and sleds, it will prevent you from considering other possibilities. Any attempts at visualization of the...

Was Jules Verne's Nautilus based on a real submarine?

  • 2,439
  • 7
Here, M. Aronnax, are the several dimensions of the boat you are in. It is an elongated cylinder with conical ends. It is very like a cigar in shape, a shape already adopted in London in several constructions of the same sort. The length of this cylinder, from stem to stern, is exactly 232 feet...

Subterrene Vehicles Traveling Underground: Past and Present

  • 4,353
  • 24
Subterrene is a vehicle that travels underground (through solid rock/soil) much as a submarine travels underwater, either by mechanical drilling, or by melting its way forward. Subterrenes existed first in fiction as mechanical drillers, with real-world thermal designs and examples following in...

19th century compressed air cars and street cars: gone and forgotten

  • 7,228
  • 11
This is actually some fun stuff folks. 150 years ago people could have been getting around by driving compressed air powered personal cars, and were boarding compressed air powered modes of public transportation. We are so duped into our internal combustion engines, that it is both sad and...
