Special Issue Information

Dear Colleagues,

This Special Issue concerns the static conversion of energy for civil and industrial use. Static energy conversion processes have numerous advantages, such as lack of friction and wear, and therefore, greater efficiency and durability, as well as lower maintenance costs, greater energy density (both in relation to volume and mass), insensitivity to the forces of inertia and volume, the possibility of operating at very high temperatures, and finally, the possibility of scaling the power values in a very wide range. Despite these characteristics, which make them particularly suitable for the use of all forms of renewable energy, these technologies are still at a limited level of development, which jeopardizes their widespread use. The purpose of this collection is to present the state-of-the-art of these processes, identifying the possible effects in terms of sustainable use of energy, mainly in the civil and mobility sectors. The focus is mainly on thermoelectric conversion, but any process that meets the above requirements falls fully among the topics of interest. Finally, special attention is devoted to those processes that combine different forms of static transformation within them.

There are several processes of static energy transformation that have reached full maturity and that the literature deals with extensively, but these technologies do not meet the requirements to be used on a large scale in developing countries or in areas with a low degree of infrastructure, due to high costs and limited efficiency or the limited level of energy that can be obtained. The object of this Special Issue will be to highlight innovative technologies that are able to determine a turnaround at the global level, first of all with regard to access to energy by a wider possible segment of the world population, but at the same time that allow to mitigate the impact of such a growth in energy demand.

Harnessing ocean wave energy is an old challenge that has gained momentum in recent years. In this paper, we present the flow and electrical characterization of a prototype of an alternate liquid metal magnetohydrodynamic (MHD) generator at a laboratory scale which has the potential to make use of the energy of marine waves for its conversion into electrical energy. The eutectic alloy Galinstan, used as a working fluid, was driven in oscillatory motion in a duct of a rectangular cross-section exposed to a transverse magnetic field generated by permanent neodymium magnets. The electric current induced by the motion of the liquid metal in the magnetic field was collected through copper electrodes and delivered to the load. The oscillatory axial velocity component along the duct was measured using ultrasonic Doppler velocimetry for different oscillation frequencies. In turn, the output currents and voltages were measured for different operation conditions and the electric power and efficiency were estimated from experimental measurements. The coupling of this generator to a wave energy converter (WEC) is discussed. Full article
