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 ...

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 ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. No extant maker's markings. This ...

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

In the Feb. 22 issue of RWEE, we asked: What is skin effect in alternating current and what is its relationship to current flow? a. Skin effect is the tendency of all current flow on printed circuit ...

The alternating fuel-to-battery Hybrid Power System 3K allows onsite generators to switch from their daily high-load power capacity demand to a battery source when lower power requirements are needed ...

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 ...

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 ...
