Conceived as a crime deterrent, some ladies makeup compacts fashioned in the shape of an inoperable pistol; complete with powder, cheek rouge and lipstick in the shape of a bullet. These were popular with Flappers from the 1920s.

Although the system of world wireless power transmission consumed most of his attention throughout his life, Nikola Tesla still brought the world many wonderful inventions and discoveries. Stated in chronological order, some of the more notable ones are:
The rotating magnetic field, 1882;
System of arc lighting, 1886;
Tesla motor and system of alternating current power transmission that utilized the rotating magnetic field discovery creating polyphase systems of AC, 1888;
Tumblr media
System of electrical conversion and distribution by oscillatory discharges, 1889;
Generators of high-frequency currents and effects of these, 1890;
Transmission of energy through a single wire without return, 1891;
The "Tesla coil,” or oscillation transformer, which was the basis to his wireless transmission of energy making Tesla the true father of radio, 1891;
Investigations of high-frequency effects and phenomena, 1891-93;
System of transmission of intelligence and power without wires, 1891-1905;
Tumblr media
Neon light signs, 1893;
Tumblr media
Researches and discoveries in radiations, material streams and emanations, today known as X-rays, and X-ray imaging, 1893-1898;
Tumblr media
Mechanical oscillators and generators of electrical oscillations, 1894-95;
Radioactivity and cosmic ray discovery published in a series of papers in the "Electrical Review," New York, 1896-1898;
High-potential vacuum tubes, 1896-1898;
Explained the harms of X-rays and safer ways to use them, 1897;
High-potential magnifying transmitter, 1897;
Economic transmission of energy by refrigeration, 1898;
Remote control, or what Tesla called his "Art of Telautomatics," 1897-99;
Discovery of stationary electrical waves in the earth, 1899;
Art of transmitting energy by stationary waves through earth, 1899-1900;
Tumblr media
Burning of atmospheric nitrogen, and production of other electrical effects of transcending intensities, 1899-1900;
Apparatus for the utilization of cosmic radiation, 1901;
Tumblr media
Art of Individualization. Tesla described this as a method of absolute privacy in wireless communication, 1902-1903;
Magnifying transmitter on a large scale, 1902;
Tumblr media
Speedometers on new principles, means for lightning protection, types of steam and gas turbines, pressure and vacuum pumps and other apparatus, 1916-1926.
Teleforce, or his “New Art of Projecting Concentrated Non-Dispersive Energy Through Natural Media.” This is his particle beam weapon, circa 1930s.

A recent invention replicates the passive reverse osmosis found in mangrove trees to desalinate salty water without the energy-intensive pumps used in traditional reverse osmosis. This process could also be used to remove dissolved particulates of all kinds, not just salt.
In the future, this invention could be utilized to make cities more water-sensitive.
“It has the potential to be used for flood reduction by incorporating it into ‘sponge cities’. These are metropolises with buildings designed to absorb and catch rainwater and reuse it, helping to reduce flooding and make cities more sustainable.”
Overall this is a great advancement for climate change resilience, sustainability, and water security.

In any case, you couldn't really imprison someone like Leonard of Quirm. The most you could do was lock up his body. The gods alone knew where his mind went. And, although he had so much cleverness it leaked continually, he couldn't tell you which way the political wind was blowing even if you fitted him with sales.
Leonard's incredible brain sizzled away alarmingly, an overloaded chip pan on the Stove of Life. It was impossible to know what he would think of next, because he was constantly reprogrammed by the whole universe. The sight of a waterfall or a soaring bird would send him spinning down some new path of practical speculation that invariably ended in a heap of wire and springs and a cry of "I think I know what I did wrong."
Terry Pratchett, Jingo

i learned that the modern gas container, the jerry can, was invented in 1937 Germany. In the start of WWII, the UK used leaky, flimsy tin containers called "flimsies" but soon captured jerry cans and the Allies started copying the German design (x)

Western society has accepted as unquestionable a technological imperative that is quite as arbitrary as the most primitive taboo: not merely the duty to foster invention and constantly to create technological novelties, but equally the duty to surrender to these novelties unconditionally, just because they are offered, without respect to their human consequences.
- Lewis Mumford

I am not a prisoner of History. I must not look for the meaning of my destiny in that direction. I must constantly remind myself that the real leap consists of introducing invention into life. In the world I am heading for, I am endlessly creating myself.

Nikola Tesla in a pre-hearing interview with his legal counsel in 1916 to protect his radio patents from Guglielmo Marconi
Tumblr media
Tesla: "This is the transmitter which was already so far developed that I obtained discharges of 16 feet and a tension of 4 million volts. The secondary flat spiral usually connects to the antenna, and this coil on the vertical stand is another tuning coil to adjust the oscillations to a low frequency. Now, it is a mere matter of proportioning this circuit to the antenna in order to transmit, with the same apparatus I built in 1895, 1896, in 1897, messages across the Atlantic with the greatest facility. I will agree at any time to construct an apparatus exactly as I have described at that time and, without the slightest change, I will affect transmission across the Atlantic as easily as rolling off a log."
Counsel: "Is that a spark apparatus?"
Tesla: "Yes, in this instance it was a spark apparatus; but I operated it also without a spark, with alternating current. I operated it with damped waves or with undamped waves. But remember that I had a system with small capacity, large self induction—no outflow of energy. Energy could not radiate; that is the reason why I got this tremendous pressure which you cannot get in an antenna which radiates too much energy in electromagnetic waves."
Counsel: " Mr. Tesla, speaking about that apparatus you said that the energy could not get out. How was the transmission then made, as for instance, across the Atlantic, or elsewhere? Is it through these earth currents that you spoke of?"
Tesla: Yes of course, through the earth currents. If I simply generated electromagnetic waves, I would be in the same box that Marconi is in, or anybody else; I would have to use an awful lot of power and I would not be able to get across. I would have to use a bigger apparatus. But, if I adapt this apparatus to the antenna in the way I want to adapt it, there is no difficult of transmitting across the Atlantic with this very same apparatus."
Counsel: " I do not yet get quite clear just what the effect is of keeping the energy from leaking out from the antenna."
Tesla: "Well, sir, I have given you the simplest mathematical formula which, of course, experts are perfectly familiar with. You are not. Now, let me explain.
"If we put it in an equation, we will have on one side the decrement of the antenna, and on the other the resistance of the antenna multiplied by the square root of the capacity divided by the self-induction..."

"Towel Wasps," said the Dean. "Well done, Archchancellor."
"Well, I mean, dammit, it's human nature, isn't it?" said Ridcully hotly. "Things go wrong, things get lost, it's natural to invent little creatures that--All right, all right, I'll be careful. I'm just saying man is naturally a mythopoeic creature."
"What's that mean?" said the Senior Wrangler.
"Means we make things up as we go along," said the Dean, not looking up.
