In the era before photography, masks — cast from molds taken directly from an individual's face or hands — were a means of making a portrait without resorting to the services (and perhaps shortcomings) of an artist. By the mid-twentieth century it was far easier to make a photographic portrait than to go to the trouble of making a mask. The detailed and lifelike quality of masks — taken from living or recently deceased individuals — ensured the survival of the process.
This copper mask captures the likeness of electrical pioneer and experimenter Nikola Tesla. It was made immediately upon the latter's death in 1943, at the request of publisher and writer Hugo Gernsback, a friend of Tesla's.
Automobiles powered by electricity have been around almost as long as there have been automobiles. In fact, in 1900, battery-powered electric cars outsold cars with gasoline-fueled internal combustion engines. But there is far more energy in a pound of gasoline than in a pound of storage batteries, meaning that gasoline-powered cars could travel farther on a tank than electric cars could on a single charge. Largely because of this, electric cars had virtually disappeared from the market by the late 1920s. By the end of the 20th century concerns about air pollution and imported oil caused people to look once again at alternatives to the internal combustion engine.
In 1997 General Motors introduced the EV1, probably the best electric car ever produced. The car was in part a response to California laws requiring the sale of a certain percentage of vehicles that emitted no pollutants. General Motors went to great lengths to overcome the limited range offered by storage batteries.

Adam Osborne, founder of the quintessential boom-and-bust Silicon Valley tech company, built the first portable computer in 1981. The Henry Ford holds examples of the few products the ill-starred Osborne Computer Corporation ever developed. What can Osborne’s innovative products and boom-and-bust company history tell us about computing and the high-tech economy?

The broad iconic power of steam engines is maintained by the continued appeal of steam locomotives—an appeal kept fresh no doubt by Thomas the Tank Engine or the Hogwarts Express of the Harry Potter series. The visual impact of the earliest stationary steam engines, while less defined in the popular imagination, is undeniable when encountered in person: early beam engines exert a powerful presence, whether through their immense scale, exposed mechanical elements, or general complexity. And there is often a note of recognition—they are often identified by visitors as distant relatives of the familiar bobbing pumps found in oilfields.
Before the Age of Steam, American farmers hand-threshed wheat or oats with a flail. Threshing machines powered by horses or portable steam engines increased daily production of threshing by a hundred times.
In the 1800s, the large number of horses required for farming consumed a lot of grain. Starting in the 1860s, farmers began threshing grain to feed those horses with a cousin of the "iron horse" - a steam traction engine like the Port Huron Thresher shown above.
As a Michigan farm boy, Henry Ford recorded his first sight of a traction engine: "I remember that engine as though I had seen it only yesterday, for it was the first vehicle other than horse drawn that I had ever seen. It was intended to drive threshing machines and power sawmills and was simply a portable engine and a boiler mounted on wheels." The steam traction engine inspired Ford to design and manufacture automobiles. To other rural people it represented a grand transition in American agriculture, and a new community activity.
