Scientists have created a material that generates energy from temperature changes, hinting at a future where solar power no longer needs panels
by Anke
April 23, 2026Excerpt: "The 'Honeycomb' barrier to break energy loss barriers
"Converting heat into electricity is a rising trend in the engineering world. However, #thermoelectrics have always been considered too inefficient for wide-scale use, until now.
"Scientists from the Seoul National University (#SNU) College of Engineering created a new material with high-performance #thermoelectric properties.
"You can review their study 'Facile and scalable strategy for fabricating dense bulk Ag2Se as a high-performance thermoelectric material,' published in Advanced Composites and Hybrid Materials.
"The team’s design is based on #SilverSelenide (#Ag2Se) and operates on the #SeebeckEffect, producing voltage from temperature gradients.
"Blocking heat while boosting the power factor"Ag2Se was scaled into nanoflakes and arranged in a honeycomb-like layout.
"Heat-carrying vibrations (#phonons) are scattered in the structure, preventing the temperature from leveling across the material.
"The material was 'doped' with #silver, which boosted the power factor by 300%, enabling electron flow despite the thermal barrier.
"This breakthrough in thermoelectric materials effectively renders the need for panels unnecessary.
"The highly efficient, thin, and flexible film has a series of application possibilities. Building integration enables solar power production from heat during the day and energy harvesting as the building cools at night.
"Flexible thermoelectric patches can power IoT devices, eliminating the use of batteries. Using the material at data centers creates a circular energy economy within digital infrastructure itself."

Maudite soit la guerre : une pensée pour tous·tes les victimes de #1418 et de toutes les guerres !

Foire le roi à #ToursPour autant le souvenir des sacrifié·es de la #GrandeGuerre ne doit surtout pas faire oublier le présent : guerres et génocides du Caucase à l'Afrique des grands lacs... 1/2

Matignon annonce la suppression du SNU au 1er janvier, « dans un contexte de création prochaine du service militaire volontaire (SMV) », annoncent les services du Premier ministre. Encore un grand projet de notre président qui tombe à l’eau… et l’une de ses promesses de campagne. Et Attal qui annonçait dans son discours de politique générale en 2024 la généralisation du SNU à partir de la rentrée scolaire 2026. Comme le temps file…

Loin d’être une bonne nouvelle, on se retrouverait avec une mesure récupérant le pire du SNU et évacuant les aspects « positifs » qui lui servaient de vitrine.

Macron montre toute sa considération pour la protection des enfants en nommant l'ancienne ministre Sarah EL Haïry haut-commissaire à l'enfance. Pas de ministère de plein exercice donc, et une apparatchik issue du MoDem plus connue pour ses "maladresses" de communication sur le SNU et la biodiversité que son travail sur ces sujets... "Du travail? Je traverse la rue, je vous en trouve", répète notre président. Enfin une promesse tenue... pour ses affidés.
