Thermal simulation and optimization of a Curie-based thermomagnetic motor harnessing concentrated solar energy

AIP Advances
This work reports on a numerical study of a thermomagnetic motor with the active material being a Nickel (Ni) plate using the Curie effect. The main goal is to use thermal simulation and parameter optimization to increase the motor’s efficiency.

Towards a better understanding of avian collision in wind energy facilities using automatic detection systems

Journal of Applied Ecology, Volume 62, Issue 6, Page 1437-1448, June 2025.
Data from automatic detection systems are a promising non‐invasive approach that requires few human and logistical resources to develop a more comprehensive bird collision risk mitigation strategy. They can be valuable to biodiversity stakeholders to highlight environmental factors that locally increase bird exposure and sensitivity, to avoid ...

Energies renouvelables : l’un des pivots du développement durable en Algérie [PDF]

International Journal of Advanced Research on Planning and Sustainable Development, 2021
La croissance demographique mondiale engendre, de plus en plus, une forte consommation d’energie. Les energies fossiles : les hydrocarbures et le charbon fournissent 86% de l’energie utilisee. Les reste est fournit par le nucleaire et les energies renouvelables. Les energies fossiles sont non renouvelables.

In Tune With the Times? When Neo‐Peasants Choose Animal Traction to be Part of a More Sustainable Production Model

Sociologia Ruralis, Volume 65, Issue 1, January 2025.
ABSTRACT As regards alternative agricultural practices today, it is worth noticing the increase in the use of animal traction (AT) in France. Yet, the reasons for this reappropriation remain unclear. The life paths and motivations of users are the focus of this article. The study is based on 33 qualitative interviews with French farmers. It uses Gasson'

Insectivorous bats alter their flight and feeding behaviour at ground‐mounted solar farms

Journal of Applied Ecology, Volume 61, Issue 2, Page 328-339, February 2024.
The negative effects of solar farms on bat flight and feeding behaviour should be considered when solar energy projects are planned. Research is needed to understand the mechanisms underlying the effects; for example, shading underneath solar panels may reduce plant biomass and therefore insect prey availability.

Voltage and Current Balancing of a Faulty Photovoltaic System Connected to Cascaded H‐Bridge Multilevel Inverter

International Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.
A healthy operation of photovoltaic installations (similar to all electrical systems) is always limited by breakdown, degradation due to aging, or imbalance caused by weather conditions. In this context, producing the maximum energy possible with an acceptable form factor is a significant challenge for autonomous systems, especially those connected to ...
