Chapter IV. treats of those dynamo-electric machines which generate continuous currents, beginning with Pacinotti's machine of 1863, and including the well-known forms of Gramme and Siemens (v.

In 1867, Werner von Siemens, Charles Wheatstone, and S.A. Varley nearly simultaneously devised the “self-exciting dynamo-electric generator ... He further refined the machine in subsequent ...

An all-electric “seaglider” that can transition ... which would make it the largest battery-powered flying machine in the world – albeit one that must remain just above the water’s surface.
