largely of wood, framed with iron hoops, and again, a Brayton-cycle engine provided motive power." The project was plagued by a "shoestring budget" and Zalinski mostly rejecting Holland's ideas on improvements. The submarine was ready for launching in September, 1885. "During the launching itself, a section of the ways collapsed under the weight of the boat, dashing the hull against some pilings and staving in the bottom. Although the submarine was repaired and eventually carried out several trial runs in lower New York Harbor, by the end of 1886 the Nautilus Submarine Boat Company was no more, and the salvageable remnants of the Zalinski Boat were sold to reimburse the disappointed investors." Holland would not create another submarine to 1893. 1885: Galileo Ferraris of Livorno Piemonte, Kingdom of Italy reaches the concept of a rotating magnetic field. He applied it to a new motor. "Ferraris devised a motor using electromagnets at right angles and powered by alternating currents that were 90° out of phase, thus producing a revolving magnetic field. The motor, the direction of which could be reversed by reversing its polarity, proved the solution to the last remaining problem in alternating-current motors. The principle made possible the development of the asynchronous, self-starting electric motor that is still used today. Believing that the scientific and intellectual values of new developments far outstripped material values, Ferraris deliberately did not patent his invention; on the contrary, he demonstrated it freely in his own laboratory to all comers." He published his findings in 1888. By then, Nikola Tesla had independently reached the same concept and was seeking a patent. 1885: Nikolay Bernardos and Karol Olszewski of Broniszów were granted a patent for their Electrogefest, an "electric arc welder with a carbon electrode". Introducing a method of carbon arc welding, they also became the "inventors of modern welding apparatus". 1885–1888: Karl Benz of Karlsruhe, Baden, German Empire introduces the Benz Patent Motorwagen, widely regarded as the first automobile. It featured wire wheels (unlike carriages' wooden ones) with a four-stroke engine of his own design between the rear wheels, with a very advanced coil ignition and evaporative cooling rather than a radiator. The Motorwagen was patented on January 29, 1886, as DRP-37435: "automobile fueled by gas". The 1885 version was difficult to control, leading to a collision with a wall during a public demonstration. The first successful tests on public roads were carried out
