Flux compression generators (FCGs) are high-energy power supplies that are capable of delivering joules to megajoules to loads. There are different types of generators, where each type has its advantages and disadvantages. One possible significant disadvantage of all FCGs is high G-force survivability. To address this issue, a new FCG design is being developed. This new generator, called a Shoc...

Amorphous Fe73B7Si16Nb3Cu1 ribbon was crystallized rapidly by electric current heating under simultaneously applied tensile stress along the ribbon axis. As a result, strong transverse magnetic anisotropy was induced in the ribbon. Dynamic magnetic properties of the ribbons rapidly heated either under the tensile stress or without tensile stress were measured using toroidal cores. Optimal elect...

The technical infrastructure is of crucial importance for modern society and electric power supplies are of particular importance. Society's dependence on electrical energy, communications and information technology is increasing. At the same time users, both industry and households, have overconfidence in technical infrastructure functionality and little preparedness for outages in the power n...

Harvesting energy from ambient vibration is proposed as an alternative to storage based power supplies for autonomous systems. The system presented converts the mechanical energy of a vibration into electrical energy by means of a variable capacitor, which is polarized by an electret. A lumped element model is used to study the generator and design a prototype. The device has been micromachined...

Multi-energy systems can integrate heat and electrical energy efficiently, using resources such as cogeneration. In order to meet energy demand cost-effectively in a multi-energy system, adopting appropriate energy resources at the right time is of great importance. In this paper, we propose an expansion planning method for a multi-energy system that supplies heat and electrical energy. The pro...

The United Kingdom has declared a climate change policy of 100% reduction in carbon dioxide emissions by 2050. Efforts thus far have been limited solely to electricity generation methods. While progress admirable, effort now must be directed at the nation’s non-electrical energy use. Nuclear is an essential part any future, since it low-carbon, firm and supplies synchronous electricity; however...
