Kempton Steam Museum - The Mercury Arc Rectifiers
Kempton Steam Museum volunteer David Walker describes the history and operation of the museum's Mercury Arc Rectifiers.
Mercury Arc Rectifiers are designed to convert AC to DC. The units at Kempton Steam Museum were originally installed at the Royal Opera House in Covent Garden to drive stage winches and motors. When they became redundant, they were rescued by museum volunteers and installed at Kempton to replicate units that were once used on the site. They are still regularly used to power the museum's heavy duty electrical equipment and can be seen operating on open days.

    I worked in an engineering company that closed in 2003 and they had 3 of these for the dc control on the cranes , one got broke in the late 80s pre internet days and the maintenance foreman found it very difficult to source a replacement, he finally got one from a disused picture house in London .

    If you chaps are at all knowledgeable about Mercury I'd love to ask a few questions...I should write you a long email lol For example I have this working theory that the so called Star Shafts in the Queens chamber was actually filled with liquid Mercury. The Queens Chamber's Star Shafts ------------------------------------------------------ The Star Shafts in the Queens Chamber would have been filled with liquid Mercury Keep in mind that if you apply a magnetic source & electricity to Mercury then you can make that Mercury spin almost as fast as the speed of light/ There is no logical reason they would have left a 5" partition between the Shaft and the Chamber unless they needed a strong magnetic source to penetrate the 5" & it also appears there was an electrical source at the top of the shaft Also notice the Star Shafts are in the shape of a giant tuning fork, this is because it is in fact a giant tuning fork. If they could adjust the amount of current being applied to the Mercury then they could adjust the speed & tone of the tuning fork. this vibrational energy would permeate throughout the entire structure, vibrating the stone & creating electrons in the process Also note In 2018 Scientists built a small scale model & discovered the Pyramid naturally focuses electromagnetic fields in its "chambers" and down into the Earth I'm assuming that magnetic force would be enough to activate the Mercury thru 5" of granite & help make it spin, also there maybe missing items in the Queens chamber that would make a magnetic field The Grand Gallery ----------------------------------------------------------- When the vibrations reached the grand gallery they would cause the row of tuning forks (now missing) set in the slots along the walls to vibrate in sympathy. Of course when you strike one tuning fork all other tuning forks in the area will resonate in sympathy if they are set to the same frequency. It is also possible they constructed the Grand Gallery to resonate at the same frequicies as the rows of tuning forks, thus when the Forks resonated the Chamber itself would also resonate & this would cause the Forks to gain energy & vibrate even louder...then that would cause the Chamber walls to increase...So back and forth they would create a powerful harmonic wave... So this is a powerful NEW frequency, not the same as the Q.Chamber The Kings Chamber ---------------------------------------------- Still working on this part of the machine but it was also intended to create vibrations Couple of points though... *I think the Sarcophagus was another tuning fork, perhaps the Vat contained a liquid that would resonate at a different frequency. *Also the extra thick layer of stone running parallel to the K. Chamber was to isolate vibrations & separate them, as well as the doors sealing the chamber *This also means they were seeking specific frequicies for a specific purpose Water below ------------------- Some other people had theories I like very much about pulsating water at the base of the Pyramid causing a sonic thumping & this pumping motion would cause the stone to slightly rise & fall, Thusly creating electrons in the vibrating stone Also water was used to pump in large amounts of +electrons like an industrial conveyor belt Vibrational frequencies ------------------------------------ The first purpose of the Pyramid was to collect as many of the Earths naturally occurring electrons outside & also to make its own electrons as well, much like a Van De Graaff generator it collects and stores the energy until its released via the capstone. When the different Vibrations form the tuning forks vibrated the entire structure it generated electrons out the wahoo & also energized the tons of quarts crystals embedded in the stone as well The Second purpose was to create powerful vibrational frequencies & combine them. I would not underestimate the power of vibrations or sound as its one of the most powerful things in the universe. Although I'm not sure exactly how at this point I think they combined the different frequencies to make a beam, this would help transfer the electrons up into the ionosphere thru the capstone to above the Earth and just as Tesla theorized people could then tap into this power source & utilize the free energy *also there are 9 key frequicies - from these you can create anything at will - so is it possible all nine were included in the design of the structure? It's important to realize mixing different frequicies is a very powerful technology, everything has it's own unique frequency The Toroid structure ------------------------------------ A Pyramid is also a cone shape & a cone shape is also a toroid - same thing...But a Toroid is also like a Van De Graaff generator too. Basically they were filling up a (powerful, don't under estimate) cone shape (the Pyramid) and energizing the electrons so that when they shot it out the top of the capstone it would all be compressed into a powerful beam of energy & the natural shape & form of the toroid would cause the mixture to mix like a blender add lots of vibrations and a dash of lemon juice & what do you get? Free global energy Tesla was right ------------------------ They built the Pyramid to be eternal The entire machine was designed to harvest Earths natural energy & do so so with little or no moving parts to replace, maintain to repair. It was pure genius in it's simplicity of function & design, we are mere insects in comparison A machine comprised of mostly vibration

    What about Electrons & Ions? or more specifically - Say you built a very large Pyramid out of tons and tons of stone, the purpose of was to generate as many positive ions (or would you want neg ones?) to shoot thru the capstone & charge up the ionosphere. if the Arc plasma can transmute AC to DC then why not instantly flip ions too?

    This would help the United States and the rest of the world convert to long-distance superconducting DC and for DC fast-charging from high voltage alternating current. Theoretically you could also use laser light pulses for alternating current to DC. 🇺🇲

    Worked with London Underground's power distribution, most Hewetic rectifiers had long since been converted to diods in 70's Though the cabinets retained their glass or mesh panels. Only MAR I saw was at Belsize Park station for it's 1 lift it operates. With Whip & Bourne plinth mounted DC breaker. Also old British Thompson Houston refectifers at South Kensington. Whole traction substation had open copperwork at 11kv. Nightmare isolating those things, with blade switches and open live slate panels at Barking Substation.

    fascinating to think an installation of similar operating principles could be found on the Triumvirate of the White Star Line, OLYMPIC, TITANIC and BRITANIC. only differentiating factor was those installation going to sea were in most cases straight DC set ups

    I wish you could of shown the precipitation of vaporized mercury in to the top parts of the dome where it runs in streams back down in to the mercury pool. That would of required running at load for some time. I am surprised that you did not have a piece of ultraviolet blocking glass in front of the bulbs. You can roast your eyeballs (and skin) from the UV from those rectifiers when they are in operation.

    I guess there must have been plenty of these mercury arc rectifiers on the third-rail system which began operating here in SE England beginning in the 1930s until relatively recent times. This type of rectifier for its size was the only device capable of handling high power until modern semiconductor rectifiers came along. It is noticeable that the present lineside power sets are much smaller than their predecesors.

    My late grandfather was an engineer and was involved as a consultant in the construction of our local museum of transport and technology in Auckland, NZ. He explained to me that when the trolley buses were phased out in Auckland in the 70' - 80's the mercury arc rectifiers were relocated to a building at the museum to supply DC to the trams that run from the museum to the Auckland zoo and on to the aircraft museum down the road. Visitors to the museum are able to stand and watch them operating.

    I remember visiting the Science Museum in South Kensington as a child (late 1960s) where they had two of these on show, one you could start with a little brass button and the other was started by turning a brass knob that I imaging brought a magnet into close proximity to the springy arc start electrode. By the late 1980s they were gone, I guess the industry had moved to Semiconductor Rectifies so they weren't 'leading edge technology' to be in the museum anymore. The 'Gas Generation' and 'Coal Mine' exhibits went about the same time - makes me feel like a dinosaur.
