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 ...

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 ...

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 ...

The late Nikola Tesla was a spectacular eccentric scientist and showman. Sure that his name will outlive Thomas Edison’s, Tesla’s admirers hold that he and Michael Faraday were the greatest electrical ...

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 ...
