Here is the one more piece of pure classics - a publication released more than a century ago to provide the marine engineers of that time with the essential information related to the ships featuring electrical propulsion. Despite rapidly developing and changing technology, the basic points raised by the author of the volume, remain valid.

After a short introduction, there is a section of the sizes of the ships and how the ships are powered. Then, the author provides some analysis of the energy required to propel the vessel at the constant speed, in ton-miles. This is followed by the chapters of interest not only for the marine engineers but also for the naval architects, because here such the important aspects as the momentum of ships and frictional resistance of the hull, speed and propeller efficiency, steam turbines together with the mechanical and electrical speed-reduction gear, are dealt with.

The use of the superheated steam has also been addressed. Then, we are coming to the internal combustion engines as the last step before the electrical propulsion. Having covered the basic intro, the author proceeds to the description of the electrical propulsion systems, explaining their technical features.
