station, which turned the two Thury 6-pole dynamos that each produce 1000 to 1100 volts at 45 amperes. In order to keep the same current, their speed varies from 20 to 475 rpm, regulated by changing the flow through the water turbine. The circuit supplied 15 motors along the line stretching to Genoa, including a 60 hp (44 kW) motor at the railway station, and motor transformers at
Central Electric Lighting Station in Genoa. Additional generation plants followed providing lighting as well as motive power to a number of mills, factories and railway repair shops.

221:, and then changed as technical director for the A. & H. de Meuron Cuénod, where he designed his multipole dynamo for which he was awarded a patent in 1883. During 1882, Thury built a six pole dynamo to this design that yielded a much more compact dynamo than those of Edison. At the 1884 Turin exhibition it won the gold medal. Over the period 1883 to 1926 his ideas resulted in 19 additional patents.

The main limitations of the Thury system was that series distribution meant greater opportunity for power failures. Placing loads in series means that since current must flow through each device to get to the next, if the circuit is broken in any of the devices, the current stops at all other loads.

system transmitted 20 megawatts of hydroelectric power a distance of 124 miles (200 km), including 6 miles (10 km) of underground cable. The system used eight series-connected generators with dual commutators for a total voltage of 150,000 volts between the poles. The system was steadily

England, Hungary, Russia, Switzerland, France and Italy. Thury systems operated up to the 1930s, but the rotating conversion machinery required high maintenance and had high energy loss.

Nussberger who financed the project. It could reach 50 km/h and would be one of the first Swiss built cars. In 1904, Thury produced a gasoline electric parallel hybrid, whose all electric range was 40 km with a 550 kg battery, or 5 km

Gorzente River, and were interested whether turbines for electrical generation might address their long standing problem of reducing excess pressure. The first turbine of 140 hp (100 kW) was installed at Galvani

An example of the mechanical voltage conversion employed was described for the lighting of

In 1882, Thury's 6 pole dynamos were more compact than Edison's. The small 1,300 kg (2,900 lb) version produced 22 kW at 600 rpm, while a larger 4,500 kg (9,900 lb) version produced 66 kW at 350
