Let's celebrate the scientific spirit with joy and sense of humor together!
Converting thermal radiation into electricity: a milestone is reached
Chapeau
Research teams from CETHIL in Lyon and IES in Montpellier have demonstrated the possibility of converting thermal radiation from a moderate temperature surface (~ 450 °C) into electrical power with an efficiency greater than 10%. By approaching the emitting surface at a short distance from the infrared photovoltaic cell, an electrical power density a thousand times higher than that of previous studies was obtained.
"A technical approach of buildings will not be sufficient to meet the energy challenge"
Chapeau
Op-ed article written by Lucie Merlier, Assistant Professor at CETHIL, published in newspaper Le Monde
Conference on "Climate change, how to act?" : CETHIL has some solutions
Chapeau
What actions should be taken to fight global warming? How can we imagine the transformation of our major energy, urban, societal systems, ? What can we do to face this great global challenge? How to mobilize individually and collectively? The purpose of this conference is to propose solutions.
How to cope with heat waves? A researcher of CETHIL answers to newspaper "Le Progrès"
Chapeau
Christian GHIAUS, faculty at CETHIL, reminds us that the human body is an engine that consumes energy, and that it is necessary to facilitate the dissipation of this energy towards the environment during periods of hot weather.
Hybrid thermionic near-field thermophotovoltaic converter
Chapeau
The conversion of thermal energy into electrical energy would make it possible to overcome the problem posed by the intermittency of solar or wind energy. Different paths are currently being studied, and a new concept has just been proposed: a hybrid near-field thermophotovoltaic/thermionic device.
