Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a ...

While they are a more eco-friendly solution you can use inside the home, power stations can’t create power; they run on ...

Traditional power stations are increasingly being replaced by wind and solar power plants – but that means the power grid lacks a stable pacemaker. Researchers from ETH Zurich are developing a control ...

THE Bulletin des Séances de la Société française de Physique for the second quarter of last year contains an interesting article by M. Boucherot on the general principles which enter into the design ...

In the future, Europe is to be dominantly powered by renewable energy. The expansion of wind and solar power capacity and the provision of sufficient power in winter are just two of the challenges ...

As shown by the sub-title, this work is addressed to students of wireless telegraphy. It outlines, without very elaborate mathematics, the general principles of alternating currents and their ...

An electric current can be induced in in a coil of wire by moving a magnet in and out of the coil. AC generators are used in the generation of electricity and in their simplest form consist of a coil ...
