Heavy-Duty DC Motor / Trolley / SubwayFaraday proved an electric motor was possible but, like his many inventions, neither scaled the idea up nor commercialized it. Voltaic piles at that time were the sole source of electricity. Because they produced little electricity high-power motors seemed pointless. Background The new field of electricity interested Sprague, a Navy officer. While serving in the … Continue reading "Heavy-Duty DC Motor / Trolley / Subway"
Electric Arc WeldingElectric arc welding lowered the price of joining metal pieces, eventually enabling the construction of much larger structures. Russians love to build giant things, bolshoya as they say in Russian. Therefore, it makes sense that it was a Russian, Benardos Nikolai Nikolaevic, who realized in 1881 that two metal pieces can be tightly joined together … Continue reading "Electric Arc Welding"

Laser PrinterLaser printing is the only Xerox research project to generate significant revenue and profit for the company. However, it predates PARC. Subsequently, most Xerox laser printing revenue came from licensing the technology to other firms. Despite their success in the enterprise market and strong brand Xerox never built a widely used Xerox-brand laser printer. Background … Continue reading "Laser Printer"
Industrial RobotThough understated at the time, few inventions have had as much impact as the industrial robot. Industrial robots were invented by George Devol.
