Reference excerpt

John Ernst Worrell Keely (September 3, 1837 – November 18, 1898) was an American fraudster and self-proclaimed inventor from Philadelphia who claimed to have discovered a new motive power which was initially described as "vaporic" or "etheric" force, and later as an unnamed force based on "vibratory sympathy", by which he produced "interatomic ether" from water and air. Keely's claims were highly disputed throughout his career and, in the 21st century, are generally considered to be pseudoscientific. Keely secured substantial investments from many people, including John Jacob Astor IV. Despite numerous requests from the stockholders of the Keely Motor Company, which had been established to produce a practicable motor based on his work, he consistently refused to fully discuss the principles on which his motor supposedly operated and also repeatedly refused demands to produce a marketable product by claiming that he needed to perfect his inventions. He became embroiled in several lawsuits, and after Keely's death, evidence of his elaborate fraud was discovered.

Biography Born in Chester, Pennsylvania, John Keely was orphaned in early childhood and was raised by his grandparents. Before becoming an inventor, he worked as a member of a theatrical orchestra, a painter, a carpenter, a carnival barker, and as a mechanic.

Career In 1872, Keely invited scientists to a demonstration at his laboratory at 1422 North Twentieth Street, Philadelphia, of a machine that he asserted was motivated by a new and previously unknown force. Keely announced that he had discovered a principle for power production based on the musical vibrations of tuning forks and that music could resonate with atoms or with the aether. In the 19th century, luminiferous aether was the hypothesized substance that allowed light waves to propagate through the vacuum of outer space. Public interest was aroused, and within a few months, the Keely Motor Company was formed in New York, with a capital of $5,000,000, equivalent to $95 million in 2013.

Keely's theories Keely delivered descriptions of the supposed principles of his process on various occasions. In 1884, following the demonstration of his "vaporic gun":

Stripping the process of all technical terms, it is simply this: I take water and air, two mediums of different specific gravity, and produces from them by generation an effect under vibrations that liberates from the air and water an inter atomic ether. The energy of this ether is boundless and can hardly be comprehended. The specific gravity of the ether is about four times lighter than that of hydrogen gas, the lightest gas so far discovered. Following a demonstration in June 1885:

It is an elaboration of interatomic ether by vibration. The atomic ether vibrates all around the molecules of matter. There is a magnetic force attached to it at the same time, and it assimilates with the molecular atomic aggregations — that is, assimilates with a certain attractive force that it is hard to tell what it is. I call it a vibratory negative. It don't act like a magnet drawing metals toward it. There is a certain magnetic effect about it that causes it to adhere by vibratory rotation to different forms of matter — that is the molecular, atomic, etheric, and ether-etheric. The impulse is given by metallic impulses, the rotary power that is formed by etheric vibration — that is the force that holds it in position. In the 19th century, most physicists believed that all space was filled with a medium called the "luminiferous aether" (or "ether"). This hypothetical substance was thought necessary for the transmission of electromagnetic waves and the propagation of light, which was believed to be impossible in "empty" space.

Etheric generator On November 10, 1874, Keely demonstrated an "etheric generator" to a small group in Philadelphia. Keely blew into a nozzle for half a minute, then poured five gallons of tap water into the same nozzle. After some adjustments, a pressure gauge indicated pressures of 10,000 psi, which Keely said was evidence that the water had been disintegrated and a mysterious vapor had been liberated in the generator, capable of powering machinery. In subsequent demonstrations, he kept changing the terminology he used, from "vibratory-generator" to a "hydro-pneumatic-pulsating-vacu-engine" to "quadruple negative harmonics". It was later reported that the witnesses of the demonstration were so impressed that they formed a stock company, purchased patent rights for the six New England states, and paid $50,000 in cash for their share in the invention. The New York Times reported in June 1875 that Keely's new motive power was generated from cold water and air and evolved into a vapor "more powerful than steam, and considerably more economical". It reported that Keely refused to disclose what the vapor was or how it was generated until he had taken out patents in "all the countries of the globe which issue patent rights", estimated to cost around $30,000. Keely said that the discovery of this new energy source was accidental. He said that the apparatus by which it was generated was called a "generator" or "multiplicator", from where it was then passed into a "receiver" and from there to the cylinders of a steam engine. The "generator" was reported as being about 3 ft (0.91 m), made of Austrian gunmetal in one piece and holding about 10 or 12 gallons of water. Its inside consisted of cylindrical chambers connected by pipes and fitted with stopcocks and valves. The "receiver" or "reservoir" was about 40 in (1,000 mm) long by 6 in (150 mm) in diameter and connected to the "generator" by a 1 in (25 mm) diameter pipe. Keely claimed that his apparatus would generate his "vapor" from water solely by mechanical means without using any chemicals and claimed to be able to produce 2,000 psi in 5 seconds.

Worked examples

Example 1 — a first encounter with John Ernst Worrell Keely

Start with the simplest possible case. Write down what John Ernst Worrell Keely claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to John Ernst Worrell Keely before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about John Ernst Worrell Keely ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of John Ernst Worrell Keely

In research
John Ernst Worrell Keely appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses John Ernst Worrell Keely in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
John Ernst Worrell Keely is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1837 births, 1898 deaths, 19th-century American inventors, so understanding it makes those chapters shorter.
In everyday life
Look for John Ernst Worrell Keely outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
