✦ Synopsis

The many advantages possessed by induction electric machines, over those producing electricity by friction, have caused the latter to be almost entirely discarded as a source of static electricity. Of these induction machines, the " Holtz " is, perhaps, the best known~ and many modifications of this machine have been designed to render it self-charging and constant in action. When, however, the plate form is adopted, the limit to the size of the revolving plates, with the ordinary materials and space that can be allotted, is soon reached. With glass plates the speed of running is limited by the fragile nature of the glass itself.
